Kundli matching, explained properly
Kundli matching, also called Kundli Milan or Guna Milan, compares two birth charts against eight traditional criteria and produces a score out of 36. It is one of the oldest parts of the Indian marriage conversation, and one of the least well explained.
Most families are handed the number and nothing else. This page explains what the number is made of, which parts of it carry real weight, and where the tradition itself disagrees with the tradition.
Free. You will need a birth date, and a birth time if you have one.
The score is eight separate tests, not one
The 36 points are divided across eight Kootas, and they are not divided evenly. Two of them carry nearly half the total between them, which is why a score can collapse without anything else changing.
- Nadi — 8 points. Constitutional compatibility. Scores zero or eight, nothing between.
- Bhakoot — 7 points. The angular relationship between the two moon signs. Also all or nothing.
- Gana — 6 points. Temperament, sorted into three groups.
- Graha Maitri — 5 points. Whether the planets ruling the two moon signs are considered friendly.
- Yoni — 4 points. Instinctive compatibility, read from animal symbols.
- Tara — 3 points. Counted distance between the two birth stars.
- Vashya — 2 points. Mutual influence.
- Varna — 1 point. The smallest weight of the eight.
Why a low score is usually one thing, not everything
Nadi and Bhakoot together are 15 of the 36 points, and both are scored all-or-nothing. If both come out at zero, the couple loses 15 points before any of the other six are considered — a pair that agrees on everything else still cannot score above 21.
This is why the breakdown matters more than the total. A score of 18 built from six strong Kootas and one Nadi failure is a completely different picture from 18 spread evenly as mediocrity, and the single number cannot tell the two apart.
Where astrologers legitimately disagree
Several of the tables involved have more than one accepted form. The Vashya categories for Dhanu and Makara are split in the classical text and simplified in common North Indian practice. Manglik cancellation rules vary widely — some traditions accept half a dozen, others almost none. The mean lunar node is standard in Panchang work, while some software uses the true node, and the two differ by up to 1.6 degrees.
None of this makes anyone wrong. It does mean that if two astrologers give you different totals for the same couple, the likely explanation is a difference of convention rather than an error, and it is worth asking which convention each of them used.
Birth time is the weak link
The eight Kootas are all calculated from the Moon’s position, which moves about 13 degrees a day. That makes them relatively forgiving: an hour of uncertainty in the birth time rarely changes a Koota.
The ascendant is a different matter. It moves a full degree every four minutes, so an hour’s error moves it fifteen degrees — half a sign. Anything derived from the ascendant, including houses, the Dasha timeline and the strictest form of the Manglik assessment, is meaningless without an accurate time. Software that quietly assumes noon when the time is unknown is not producing a weaker reading; it is producing an invented one.
What Kundli matching cannot tell you
It cannot tell you whether a marriage will work. No study has shown a relationship between Guna scores and marital outcomes, and anyone who tells you otherwise is selling something.
It cannot tell you anything about a person’s character, conduct, honesty or intentions. A birth chart is calculated from a date, a time and a place; it contains no information about how someone has behaved.
It cannot verify that a person is who they say they are. That is a separate question with separate evidence, and it is the one VerifyShaadi was built to answer.
Common questions
What is a good Guna score for marriage?
Traditionally 18 or more out of 36 is treated as an acceptable match, and above 28 as a strong one. These thresholds are conventions, not measurements, and the breakdown across the eight Kootas is more informative than the total — a score of 18 can come from one heavily weighted failure or from mediocrity across the board, and those are very different situations.
Is Kundli matching necessary for marriage?
No. It is a cultural and interpretative practice, not a legal or medical requirement, and many families marry without it. Whether it matters is a decision for the people involved.
Can Kundli matching be done without a birth time?
Yes, for the eight Kootas. They are calculated from the Moon’s sign and birth star, which do not need a precise time. The ascendant, the houses and the Dasha timeline do need one and should be left out rather than estimated.
Why do two websites give different Guna scores for the same couple?
Almost always a difference of convention: a different ayanamsa, a different Vashya or Manglik table, or the true lunar node instead of the mean node. Ask which settings each used. A reputable calculation states its ayanamsa, house system and methodology alongside the result.
Does a low Guna score mean the marriage will fail?
No. There is no evidence linking Guna scores to marital outcomes. A low score most often reflects one or two heavily weighted Kootas scoring zero rather than a broad incompatibility.
How this fits with verification
VerifyShaadi is a matrimonial background verification service. We check claims — identity, education, employment, court records — against the sources that hold the answer, and a named analyst reviews every finding.
Astrological compatibility is a separate thing entirely, and we keep the two apart. A Kundli report is calculated from birth details that people give us and that we have not independently checked. It is never described as verified, and a compatibility score is never part of a verification result.
