For families across the diaspora, kundli matching is usually the one piece of the tradition everyone still insists on — and the one most often done badly. A quick online tool returns a number out of 36 and a verdict. That number is real, but it is the first step of a proper match, not the last, and treating it as the whole answer is how good matches get rejected and poor ones get approved.
What Ashtakoot Guna Milan actually scores
The 36-point system compares eight kootas — attributes derived almost entirely from the two Moon nakshatras: Varna (1 point), Vashya (2), Tara (3), Yoni (4), Graha Maitri (5), Gana (6), Bhakoot (7) and Nadi (8). Eighteen or above is traditionally acceptable; twenty-four and above is considered strong. Because it rests on the Moon alone, it measures emotional and temperamental compatibility — nothing about timing, longevity or the couple's individual promise for marriage.
The three doshas that override the score
- ✦Nadi dosha — the same Nadi in both charts, worth 8 points, classically the most serious. Several cancellations exist (same rashi with different nakshatras, and others) that most online tools ignore entirely.
- ✦Bhakoot dosha — Moon signs in 6/8, 2/12 or 5/9 relationship. Often cancelled when the sign lords are friends or identical.
- ✦Mangal dosha — Mars in the 1st, 2nd, 4th, 7th, 8th or 12th house in either chart. The most over-diagnosed factor in the whole tradition; most cases cancel on inspection, and a match where both partners are manglik is considered balanced, not doubly afflicted.
What a full match adds beyond the score
A competent compatibility reading places both birth charts side by side: each person's 7th house and its lord, Venus and Jupiter in each chart, the two Navamshas, and — critically — each person's dasha timeline. Two charts that score 30/36 can still describe very different marriage timing, and two that score 20 can be more durable than the number suggests. The score tells you whether the temperaments align; the charts tell you what the marriage will actually be like.
Practical notes for matching across time zones
Birth details entered in the wrong time zone shift the Moon nakshatra and can change the Guna score outright. Always enter the birth place and local birth time, never a converted time. If either partner was born outside India, the sidereal calculation still applies — the zodiac does not change with geography — but the software must know the actual coordinates and the historical time zone rules for that place and year.
