Are We Compatible? Reading Two Charts Together

Most people arrive at this question holding one number. They have run a free kundli matching tool, it returned something out of 36, and now they are trying to work out whether 25 is a yes and whether 17 is a no. The number is real and it is worth having. It also answers only one of the four things the question is actually asking, which is why a good score and an unhappy marriage are not a contradiction, and why a low score sends so many couples looking for a second opinion that agrees with them.

This page shows what a full two-chart reading contains, using two example couples whose charts were computed end to end with the same sidereal calculation that runs AstroMedha's free tools. Every placement, score, dosha severity and date below came out of that computation. The birth details themselves are invented so that two complete charts can be shown in public, and the arithmetic on them is the real arithmetic.

The four questions hiding inside "are we compatible"

The single question splits into four the moment you try to answer it with charts.

Do the two temperaments fit? That is what the 36-point score measures, and it measures it entirely from the two Moons. Every one of the eight kootas, the eight qualities scored in Ashtakoota matching, is derived from where each person's Moon sits by rashi, the sidereal sign it occupies, and by nakshatra, the twenty-seventh part of the zodiac it was crossing at birth. The Sun, ascendant, Venus, Mars and every house placement play no part in the score at all.

Is there a specific affliction on either chart that classical matching flags? Mangal Dosha is the one people know about, and it is checked per chart, not per couple. Two charts can each carry it and cancel each other, or one can carry it alone and not cancel at all.

Is each person's own marriage axis in a state to carry a marriage? Before the two of you are compared, each chart says something on its own about partnership: the condition of the seventh house and its lord, the condition of Venus, and what the navamsha, the ninth divisional chart, does to both. A person whose seventh lord is weak does not become strong by being matched with someone who scores well against them.

Do the two timelines run supportively across the years the decision covers? Each chart is running a dasha, a planetary period in Vimshottari, the system that divides a 120-year cycle among the nine planets and colours a span of years at a time. Two people are always in different periods. Where those periods sit over the next five years decides whether the early marriage is smooth, stretched, or simply busy.

The score answers the first question. Five instruments together answer all four, and the rest of this page runs each one on computed charts.

The worked example: two charts, computed end to end

Arjun, born 18 June 1992 at 05:40 in Delhi (28.61 N, 77.21 E). Meera, born 7 December 1994 at 14:10 in Bengaluru (12.97 N, 77.59 E).

Arjun's lagna, the sign rising on the eastern horizon at the moment of birth, is Gemini at 6.13 degrees, in Mrigashira nakshatra pada 4. Four bodies sit with it in the first house: Sun at 3.26 Gemini, Venus at 4.44 Gemini, Ketu at 7.10 Gemini, and Mercury at 21.90 Gemini in its own sign, which means the sign Mercury rules. Venus sits 1.7 degrees below the rising degree itself. His Moon is at 4.68 Capricorn in Uttara Ashadha pada 3, in the eighth house, alongside Saturn at 24.40 Capricorn, which is retrograde, meaning it appears to move backwards against the zodiac as seen from Earth, and is in its own sign. Mars is at 8.70 Aries in its own sign in the eleventh. Jupiter is at 14.16 Leo in the third. Rahu is at 7.10 Sagittarius in the seventh house.

Meera's lagna is Pisces at 22.45 degrees, in Revati pada 2. Sun, Mercury and Jupiter cluster in Scorpio in the ninth house at 21.22, 17.47 and 5.76 degrees. Her Moon is at 20.66 Capricorn in Shravana pada 4, in the eleventh house. Venus is at 12.14 Libra in its own sign, in the eighth house, with Rahu at 19.28 Libra beside it. Saturn is at 12.57 Aquarius in its own sign in the twelfth. Mars is at 4.90 Leo in the sixth. Ketu is at 19.28 Aries in the second.

Both Moons are in Capricorn. That single fact drives most of what the score does next, in both directions.

Instrument one: the 36 gunas, and what they are made of

Run through Ashtakoota Guna Milan, the eight-part scoring system that totals 36 points, the pair scores 25 of 36, or 69.4%, which the scale calls a Very Good Match. The breakdown is where the information is.

The five kootas the table names without explaining, in order. Varna assigns each Moon sign a class from its element and scores when the two classes sit well together; both Moons here came out Vaishya, the class the earth signs carry. Vashya sorts the signs into categories such as quadruped, human and water-dwelling, and scores how naturally one holds sway over the other; both fall in Chatushpada, the quadruped group, so neither dominates by default. Tara, the count from one person's birth star to the other's and back again, came out favourable in both directions, which is the harder of the two conditions to meet. Yoni pairs each birth star with an animal and scores physical compatibility, and Mongoose against Monkey is a neutral pairing rather than a hostile one, which is why it took half marks instead of none. Gana sorts the birth stars into Deva, Manushya and Rakshasa temperaments, and a Deva-Manushya pairing loses one point of six. Ashtakoot matching takes each of the eight in turn.

Five kootas are at full marks, one is one point short, one is at half, and one is at zero. Both Moons being in Capricorn is what produced the perfect Graha Maitri, the friendship between the two Moon-sign rulers, since Saturn rules both signs and so is trivially friendly with itself. The same fact produced the perfect Bhakoot at 1/1, because Bhakoot penalises particular distances between the two Moon signs and zero distance is not one of them.

And the same fact is close to why Nadi returned zero. Nadi sorts the twenty-seven nakshatras into three groups and scores 8 points when the two people fall in different groups. Uttara Ashadha and Shravana are neighbours in the zodiac and both fall in the Antya group, so the pair takes the largest single deduction in the system. Nadi carries more weight than any other koota because it is traditionally read as the health and progeny axis, and a zero there is the flag that stops most family negotiations.

That zero needs one clarification. The 36-point score reports the raw koota, without applying any of the classical conditions under which a same-Nadi match is set aside. Whether one of those conditions applies to a specific couple is a separate check against both charts, and the conditions themselves are set out in Nadi Dosha in matching. Two things follow. A 25 with Nadi at zero and a 25 built from six mediocre kootas are not the same match, and no total tells them apart. And a Nadi zero is a reason to read the two charts properly, since it is exactly the case the score is worst at settling. The related deductions are covered in Bhakoot Dosha, and the threshold question itself in Minimum gunas for marriage.

You can produce this table for any two people, free and without an account, at free kundli matching. It is the only instrument of the five that needs nothing but two dates.

Instrument two: Mangal Dosha, checked in each chart separately

Mangal Dosha, the affliction counted when Mars occupies particular houses from the ascendant or from the Moon, is not a property of a couple. It is computed once per chart, and the two results are then compared.

Arjun. Mars is in the fourth house counted from his Moon, which puts the dosha on the chart. Two cancellation factors are present. Mars is in its own sign, Aries. And Jupiter aspects Mars from the fifth. The severity returned is therefore Cancelled, described as a dosha that is technically present while the cancellation factors nullify its marital effect under the classical rules, so that no special matching is required.

Meera. Mars is in the eighth house counted from her Moon, with no cancellation factor present. The severity returned is High, described as a strong Mangal Dosha affecting marriage and partnerships, with Mars in the seventh or eighth from the Moon indicating intense energy in relationships, and matching with another Manglik partner recommended.

Together. Both charts carry the dosha, which triggers the most widely known rule in Vedic matching: two Manglik charts cancel each other. The joint verdict is Compatible, and the reading records that the marriage is considered safe from Mangal Dosha affliction. Both charts had a real birth time and place, so the ascendant leg of the check ran on both, and the verdict is complete rather than partial.

Notice how much reading the word "Manglik" alone would have lost. One partner's dosha is cancelled by two independent factors and would not have needed a matching partner at all. The other's is live and severe. The pair still clears, because presence on both sides is what the cancellation rule keys on. Someone matching Meera against a chart with no dosha would be reading a different situation entirely.

The formation, the house set, the severity bands and the classical remedies are covered in depth in Mangal Dosha in matching and Mangal Dosha explained. If you want only this one check on a single chart, the free Manglik check runs it. And if you are wondering how unusual the flag really is, we measured it across 100,000 charts in How common is Mangal Dosha.

When a high score and a live Manglik flag point opposite ways

A second computed couple shows that the score and the dosha check are independent instruments which can disagree.

Partner A, born 27 January 1991 at 23:15 in Mumbai. Partner B, born 19 August 1993 at 06:55 in Chennai. Their Ashtakoota total is 28.5 of 36, rated Excellent Match, three and a half points ahead of Arjun and Meera. Their Nadi is a clean 8 of 8, different nadis, recorded as excellent for health compatibility. Their Gana is a full 6 of 6, both Manushya, an excellent temperament match.

Their Mangal Dosha result is Caution. Partner A has Mars in the twelfth house from the Moon, severity Medium, with no cancellation factor. Partner B does not carry it from the lagna: Mars sits in the second house, which is not one of the afflicting houses (1, 4, 7, 8, 12) counted from the Lagna or the Moon. One qualifier belongs with that, because it decides who agrees: Mars is in the 2nd house from the Moon, which the South-Indian Kuja-dosha set counts and the North-Indian set does not. One live dosha, one chart that is clean by the North-Indian reckoning, no mutual cancellation. The traditional remedy named for that configuration is Kumbh Vivah, the symbolic marriage performed before the wedding.

So the higher-scoring couple is the one carrying the unresolved Manglik mismatch, and the lower-scoring couple is the one whose dosha question is already settled. Rank the two pairs by the number out of 36 and you get one order. Rank them by the dosha check and you get the opposite order. Neither instrument is wrong, because they are measuring different things, and a family that has only ever seen the number has no way to know which of the two situations it is looking at.

The two charts have more to say. Partner A's seventh lord is Jupiter, exalted, which means it sits in the sign where it is strongest, in this case Cancer, and it is placed in the eleventh house and retrograde. Partner B's seventh lord is Saturn, in its own sign Aquarius, sitting in the seventh house itself and retrograde. Both marriage axes are in unusually good condition, which is the layer neither the score nor the dosha check touched.

Instrument three: each person's seventh house and Venus

The seventh house is the house of marriage and partnership, and its lord is the planet ruling the sign that falls on it. Where that lord sits, and in what dignity, which is the strength label a planet earns from the sign it occupies, says how the person's own partnership life is built. Venus is read alongside it as the natural significator of the spouse, meaning the planet that stands for that part of life in every chart regardless of where it sits.

Arjun. His seventh house is Sagittarius, so Jupiter is his seventh lord. It sits at 14.16 Leo in the third house, in neutral dignity and direct motion. A seventh lord in the third is a partnership life shaped by initiative and by what he goes out and does, rather than one that arrives and settles. Venus is the more striking placement: at 4.44 Gemini it sits 1.7 degrees below his rising degree, in the first house, in neutral dignity. Venus on the ascendant puts partnership at the centre of how he presents himself and how others read him. Rahu sits in his seventh house at 7.10 Sagittarius, which classically reads as strong and unconventional pull in partnership, and as an appetite that wants more than the ordinary version of the thing. His darakaraka, the planet holding the lowest degree in the chart and read in the chara-karaka scheme as the significator of the spouse, is the Sun, placed in the first house in Gemini.

Meera. Her seventh house is Virgo, so Mercury is her seventh lord. It sits at 17.47 Scorpio in the ninth house, in neutral dignity and direct motion, with Sun and Jupiter in the same sign. A seventh lord in the ninth ties partnership to belief, teachers, distance and the family's larger frame, which in practice reads as a marriage that has to make sense inside a worldview and not only inside a household. Her Venus is at 12.14 Libra in its own sign, which is the strongest thing in her chart on this axis, and it sits in the eighth house with Rahu in the same sign. Venus strong by sign and placed in the eighth reads as depth of attachment held privately, with the intensity turned inward rather than displayed.

Her darakaraka is Mars, at 4.90 Leo in the sixth house, and Mars is the same planet carrying her live Manglik severity. When the significator of the spouse and the afflicted planet are one body, the partnership theme and the Mars theme are not separable in her chart. The practical reading is that conflict style is the thing to work on directly rather than the thing to hope around, and the concrete version of that is agreeing in advance how a disagreement gets paused and picked up again, rather than settling it in the moment.

None of that reading is available from a score. All of it comes out of one chart at a time, and all of it is needed before the comparison means anything.

Instrument four: the navamsha, the chart marriage is judged in

The navamsha, the ninth divisional chart, is built by cutting each sign into nine parts of three degrees twenty minutes each and reading where every planet lands. It is the chart traditionally read for marriage. A planet that looks strong in the birth chart and collapses in the navamsha does not deliver what it promised, and a planet that gains there delivers more than the birth chart suggested.

Arjun's navamsha. His navamsha ascendant is Scorpio. Jupiter, which is his seventh lord, is vargottama, meaning it holds the same sign, Leo, in both the birth chart and the navamsha, which is the strongest form of continuity a planet can show between the two. It also falls in a pushkara navamsha, one of the divisions classically marked as nourishing. His navamsha seventh house is Taurus, ruled by Venus, and Venus in the navamsha sits in Scorpio, which is his navamsha ascendant. So the lord of his navamsha seventh occupies his navamsha first, and the marriage axis folds directly into the self. Mercury also lands in a pushkara navamsha, in Aries. His atmakaraka, the planet at the highest degree in the chart and the one read as carrying the main agenda of the life, is Saturn, the same planet sitting with his Moon in the eighth house.

Meera's navamsha. Her navamsha ascendant is Capricorn, with Sun, Venus and Saturn all placed in it. Her navamsha seventh house is Cancer, ruled by the Moon, and the Moon itself occupies Cancer in the navamsha, so her seventh lord sits in her seventh house in its own sign. That is about as well held as a navamsha marriage axis gets, and it is the single strongest partnership signal in either of these two charts. She has no vargottama planets. Her birth-chart seventh lord Mercury falls in Sagittarius in the navamsha, the twelfth from her navamsha ascendant, which is the one soft place on the axis. The practical form of that is a partnership life lived somewhat away from where she started, geographically or socially, and the thing to do about it is to be deliberate about the distance rather than let it accumulate by default. Her atmakaraka is the Sun.

Read across the two charts, both people carry a well-held navamsha seventh, by different routes. His is held by a vargottama seventh lord and by the navamsha seventh lord sitting in his navamsha ascendant. Hers is held by the seventh lord occupying its own sign in the seventh. Neither of them brings a broken marriage axis into the match, and that is a much better predictor of how a marriage holds than the 25 out of 36 is. If you want the mechanics of the divisional chart itself, Navamsa has them.

Instrument five: whose period runs when, over the next five years

Each person is inside a mahadasha, the major planetary period in the Vimshottari sequence, and inside that an antardasha, which is the sub-period that divides the major one among the same nine planets in the same order.

Arjun is in a Rahu mahadasha that began on 10 November 2011 and runs to 9 November 2029, after which a Jupiter mahadasha begins. As of 26 August 2026 he is in the Sun sub-period of it, from 29 May 2026 to 23 April 2027.

Meera is in a Jupiter mahadasha that began on 8 December 2021 and runs to 8 December 2037. As of 26 August 2026 she is in the Mercury sub-period, from 9 August 2026 to 14 November 2028.

Intersecting the two ladders over the next five years produces four windows of any real length.

Two short handover strips sit between them, in late 2028 and late 2029, where one person has changed sub-period and the other has not yet.

The shape of the five years is legible from the table. Meera is under Jupiter throughout, and Jupiter sits in her ninth house with her Sun and her seventh lord, so her whole period runs through the part of her chart that ties partnership to belief and to the wider family frame. Arjun spends the first three years finishing a Rahu period and the last two entering Jupiter. The strongest of the four windows for a decision that has to hold is the last one: from 9 November 2029 both people run a Jupiter mahadasha at the same time, his with Jupiter as sub-period lord too, and Jupiter is his seventh lord and is vargottama. The most demanding is 14 November 2028 to 20 October 2029, where his Mars sub-period meets her Ketu sub-period. Mars is the planet carrying the live Manglik severity in her chart, so a Mars year runs on his clock while it is the sensitive point on hers, and that is the year to keep the big decisions out of.

None of that is a verdict on the marriage. It is a calendar. What it changes is which year you schedule a hard conversation in, and which year you do not.

What the five instruments say together

For Arjun and Meera the four questions now have four separate answers, and they do not all point the same way.

Temperament fit is genuinely strong at 25 of 36, with five kootas at full marks and the whole of the large deduction sitting in one place. Nadi is at zero and needs the cancellation conditions checked against both charts rather than argued about. The Manglik question is settled and clean: both charts carry the dosha, his already cancelled twice over, and the mutual rule applies with both ascendants verified. Each person's own marriage axis is in good condition, hers conspicuously so, with the navamsha seventh lord in its own sign in the seventh. The five-year calendar has one demanding year, from 14 November 2028 to 20 October 2029, and opens into a shared Jupiter period from 9 November 2029 that runs into 2031.

Written as one sentence, the reading is that the structural work here is already done, and what remains is about conflict style and about the progeny question, on a calendar that says the harder conversations belong before late 2028 or after October 2029. That sentence is not derivable from 25 out of 36, and it is not derivable from any one of the five instruments alone.

Running this on your own two charts

The first two instruments are free and need no account. Kundli matching gives you the full eight-koota table with the same per-koota descriptions quoted above, plus the Manglik flag for both charts, from two dates. Mangal Dosha runs the dosha check on one chart, with its severity and any cancellation factors named. Kundli gives you a single chart with houses, dignities and the running period.

The other three instruments need both people's full birth records on one account, because they read each chart on its own before comparing them. What a signed-in couples reading adds to the free score is each partner's seventh lord with its house, sign and dignity, the Venus condition in each chart, both navamsha charts with the navamsha ascendant, the navamsha seventh and any vargottama or pushkara placements, and the joint period table with real dates like the one above in place of a general statement about periods. The Marriage Compatibility Report is the written version of the same reading, delivered by email.

The account is not there to hold back the number. The number is free and always will be. It is there because the remaining three instruments are impossible without two complete birth records, and a birth record is not something to type into a page that forgets it.

If one of the two birth times is unknown, run it anyway and read the result correctly. The eight kootas still compute, because they come from the Moon, and the Moon moves slowly enough that the rashi is usually safe from a wrong hour, though the nakshatra is not always. What is lost is the ascendant, and with it the lagna leg of the Manglik check, the house positions, and the navamsha ascendant. A dosha verdict computed without an ascendant is recorded as partial rather than clean, and it says so on the page. Kundli matching without birth time covers what survives and what does not.

What two charts cannot settle

Five instruments answer four questions, and all four questions are about the charts. They say nothing about whether either person wants this marriage, what the two families have agreed, what either person earns, or what a doctor would say about the progeny question that Nadi is traditionally read against. A same-Nadi result is a prompt to ask a medical question that has a medical answer, not a substitute for asking it.

The useful way to hold a two-chart reading is as a description of the terrain two people are walking into, with the difficult ground marked and dated. Arjun and Meera get a demanding year from 14 November 2028 to 20 October 2029, and a supportive one that opens on 9 November 2029 and runs into 2031. Knowing that changes what they schedule and when. It decides nothing for them, and the couples who get the most out of a reading tend to be the ones who already knew that.
