Compare Your Birth Chart With Your Partner's: Beyond 36 Gunas
Pick two strangers at random and 69% of them pass the 36-point guna test. Here is what a real Vedic compatibility reading compares in both charts, and which services actually do it.
Most people who ask me to compare their chart with their partner's arrive holding a number: 24 out of 36, or a frightening 14. That number reads only your two Moons, never your 7th house, your Navamsa or the dashas you will share. It is a first glance, never a verdict.
Supastro wrote this. Where another service does a job better, I say so.
Explain kundli matching: what does the 36-point score measure?
Kundli matching, or guna milan, scores a couple out of 36 with eight tests called kootas. All eight read the two Moons: four the Moon's sign, four its nakshatra (one of the 27 star segments of the sky). Nothing else in either chart enters the score.
| Test (koota) | Points | Reads | What it is said to describe |
|---|---|---|---|
| Varna | 1 | Moon sign | Outlook and values |
| Vashya | 2 | Moon sign | Pull and give-and-take |
| Tara | 3 | Moon nakshatra | Luck and well-being together |
| Yoni | 4 | Moon nakshatra | Physical and sexual fit |
| Graha Maitri | 5 | Moon sign lords | Friendship and how you think |
| Gana | 6 | Moon nakshatra | Temperament |
| Bhakoot | 7 | Moon signs | Emotional rhythm, money, family |
| Nadi | 8 | Moon nakshatra | Health and children |
Eighteen is the usual pass mark. The two heaviest tests carry the scary words: Nadi dosha (both Moons in the same Nadi group) and Bhakoot dosha (Moon signs 2/12, 5/9 or 6/8 apart). Both have published cancellations.
Is guna milan alone enough to decide a marriage?
No. Matching on the 36 points alone is pop astrology, and arithmetic proves it. The score can see only 38 distinct Moon positions (each nakshatra, split where it crosses a sign, plus the halfway line Vashya uses in two signs). So every couple on Earth falls into one of 1,444 boxes, and strangers born years apart get identical scores.
I scored every box with Supastro's own matching code, weighted by the share of the sky each covers, then checked it on 20,000 random couples with real Moon positions. 69% of random couples pass 18. One couple in three has Nadi dosha; one in two has Bhakoot dosha. Seven random strangers in ten "match". That tells you nothing about the one you love.
The classics agree. Parashara gives no points table at all. The one classical chapter in our library on marriage agreement, the Prasna Marga's, lists 14 factors, including each partner's Ashtakavarga, and says that if the couple love each other they may marry even when the other agreements fail. Its translator, B. V. Raman, adds that real compatibility has to exist in the two horoscopes themselves, and that the points system comes from the electional manuals, not this text.
What Vedic astrology service can compare my chart with my partner's?
Supastro, an AI Vedic astrology app built in Bengaluru by Quantum Karma, compares the whole of both charts on its free compatibility tool, no sign-up. Both charts are computed first (true Lahiri ayanamsa, whole-sign houses), then scored in eight layers; the 36-point table is one of them, not the headline.
- Core charts (20%): both 7th houses and lords, Venus, Jupiter, and how your rising signs and Moons sit from each other.
- Marriage points (15%): your Upapadas, Darapadas and Darakarakas (the spouse planet).
- Navamsa (15%) and dasha timing (15%): the spouse chart, and whether you both run relationship periods at once.
- Ashtakavarga (10%), Manglik for both (10%), the 36 points (10%) and planet links (5%).
One more thing I rate: you can make a private link with only your own birth details and send it to your partner. They add theirs and you both see the same layer-by-layer result. Nothing is stored in a database (the details travel encrypted inside the link), and it expires after 30 days.
Honest gaps: the free tool does not score the ten-koota system (the paid dashboard reading does), there is no KP, it is English only, and no human astrologer sits on the other end.
What does a real two-chart compatibility reading check?
A real reading runs every check below in both charts, then compares them.
- Both 7th houses and their lords. The 7th is the partner; a strong 7th lord gives happiness through marriage, one in the 6th, 8th or 12th strains it.
- Both Navamsa charts. Parashara reads the spouse from the Navamsa; a birth-chart promise the Navamsa denies does not deliver.
- The Upapada and the 2nd from it. The strongest single test of whether the marriage holds once it starts.
- The Darapada (A7). Daily life together: intimacy and shared money.
- The Darakaraka. The planet with the lowest degree among seven; it describes the partner you attract.
- Venus and Jupiter in both charts. Dignity, combustion, company.
- Manglik in both, with cancellations. Parashara's rule: if both carry the Mars combination, it cancels. One chart cannot tell you that.
- Ashtakavarga points in each 7th house. Can the house carry the load?
- The dashas you will both run. A good match in a bad shared period still struggles.
- Transits over both charts for the wedding year.
- Exact degrees. A planet at a sign's edge, or burnt by the Sun, changes the reading.
- Last and least, the 36-point Moon table. A first glance, never the final word.
Same 36-point score, opposite verdicts: a worked example
I searched 12,000 hypothetical births for two couples with identical Moons and ran both through Supastro's layered engine. Couple one: he was born 25 April 1994, 11:33 pm, Bengaluru; she 3 August 1991, 6:24 pm, Hyderabad. Couple two: he 30 September 2000, 6:51 am, Mumbai; she 20 October 1994, 11:30 pm, Bengaluru. Both men have the Moon in Libra (Swati), both women in Aries (Bharani). Both couples score 28.5 out of 36. Any matching site calls both a strong match.
Compare the full charts and they split. Couple one scores 89 out of 100: their marriage points sit opposite each other (the partner axis), their spouse planets work together, their Navamsa rising signs face each other, and both carry the Mars combination, so it cancels. Weak spots remain: his 7th lord is burnt by the Sun and both 7th houses score below average.
Couple two scores 8 out of 100. Their marriage points sit 6/8, the axis of friction; their Darapadas and Navamsa rising signs are 2/12; their spouse planets pull against each other; his 7th lord sits with Saturn; and the Manglik picture is one-sided (his from Parashara's verse, hers only from a later convention), so nothing cancels. Same 28.5. Opposite marriages.

What else has to be computed before this becomes a prediction?
| Layer | What I compute | How it can change the answer |
|---|---|---|
| Birth charts (D1) | Both 7th houses, 7th lords, Venus, Jupiter, rising signs and Moons | A strong guna score with a ruined 7th lord is still a hard marriage |
| Navamsa (D9) | Both D9 charts, vargottama planets, the D9 rising signs | Can confirm or cancel what the birth charts promise |
| Arudhas | Upapada, the 2nd from it, Darapada (A7) for both | Shows whether the marriage holds once it starts |
| Karakas | Each Darakaraka and Atmakaraka | Whether the two spouse planets cooperate or fight |
| Strength and degrees | Shadbala, dignity, combustion, retrograde, edge-of-sign degrees | A planet that looks good can be too weak to deliver |
| Ashtakavarga | Bindus in each 7th house; the Moon's points at the partner's Moon sign | A low score means the house cannot carry the load |
| Manglik | Mars in both charts, the verse and later conventions, every cancellation | Two Manglik charts cancel; a one-sided case needs a closer look |
| Dashas and transits | Vimshottari for both, Yogini as a cross-check, transits for the wedding year | Decides when the bond is switched on and when it is tested |
Frequently asked questions
Is 18 gunas enough for marriage?
Eighteen is the conventional pass mark, but it means little: 69% of random couples clear it. Treat 18 as "no obvious Moon clash", then compare the 7th houses, the Navamsa, the Upapada, Manglik for both and your shared dashas.
We have Nadi dosha. Should we cancel the wedding?
Not on that alone. One couple in three has it by definition, and the usual cancellations apply: same nakshatra in different Moon signs or quarters, or same Moon sign in different nakshatras. Check the cancellation, then judge the full charts.
Does Manglik matter if both partners are Manglik?
Parashara answers it himself: if a man and a woman who both carry the Mars combination marry, it ceases to have any effect. So check Manglik in both charts, with every cancellation, before anyone panics. Run the Manglik check on each chart.
Is synastry the same as kundli matching?
Not quite. Western synastry overlays two tropical charts and reads the aspects between planets. Vedic matching is sidereal and adds what synastry has no word for: the Navamsa, the Upapada, the Darakaraka, Manglik and both people's dashas. Supastro's planet-links layer is the closest thing to synastry, worth 5% of the verdict.
Can we marry with low gunas if we love each other?
The Prasna Marga says yes: if the couple love each other, they may marry even when other agreements fail. A low score is a reason to look harder at both charts, not a ban.
Do we both need exact birth times?
For the 36 points, mostly no: they come from the Moon. For everything that matters more (the 7th house, the Navamsa, the Upapada, the dashas), yes. A wrong time moves the rising sign and every house with it. Use hospital records for both.
