Free online Kundali matching (Guna Milan) for marriage, scored on the Ashta Koota system — the eight-fold method that produces the 36 gunas. The eight kootas are weighted unequally: Varna 1 point, Vashya 2, Tara 3, Yoni 4, Graha Maitri 5, Gana 6, Bhakoota 7 and Nadi 8, adding to 36. Traditional practice treats a total above 18 as a match. Ashta Koota is one system among several — the fuller traditional examination weighs further factors beyond these eight.
Kundali matching compares two birth horoscopes to assess marriage compatibility in Hindu astrology. The most widely used method is Ashta Koota — literally 'eight factors' — which scores the pair across eight categories totalling 36 points, commonly called the 36 gunas.
The eight kootas carry different weights: Varna 1 point, Vashya 2, Tara 3, Yoni 4, Graha Maitri 5, Gana 6, Bhakoota 7 and Nadi 8. Added together they give the 36-point total. The weighting matters — Nadi alone accounts for 8 of the 36, more than Varna, Vashya and Tara combined.
In common traditional practice a score above 18 out of 36 is treated as a match. The threshold is a convention of the tradition rather than a fixed rule, and families and astrologers differ on how strictly to apply it.
Nadi, at 8 of the 36 points — the single largest component of the score. Bhakoota follows at 7 and Gana at 6. Because the three together are 21 of 36, a pair can score reasonably overall and still differ sharply on the factors the tradition weights most heavily, which is why the breakdown is usually read alongside the total.
Gana classifies each person's birth nakshatra into one of three temperaments — deva (god), manushya (man) and rakshasa (demon) — and carries 6 of the 36 points. It is one of eight factors, not a verdict on its own.
No. Ashta Koota is a reduced, eight-factor system. The fuller traditional examination considers additional factors beyond these eight, and regional traditions differ in which they weigh. A single 36-point number is a summary of one method, not the whole of the tradition.
No. A 2020 peer-reviewed study by Helgertz and Scott in the journal Genus tested astrological predictions of marriage and divorce against Swedish population register data and found no supporting evidence. This calculator reports what the Ashta Koota tradition computes — it does not claim the result predicts anything about a marriage, and no one should treat a score as a reason to proceed with or call off one.
