What is actually being compared
Both people’s birth details are used to find the Moon’s position, and from that the Moon’s nakshatra and the rāśi it falls in. Every one of the eight factors is derived from those two values. Nothing else in either chart enters the calculation — not the ascendant, not the 7th house, not Venus, not the running daśā.
This is worth stating plainly because it explains both the method’s usefulness and its limits. It compares two people’s Moon positions against a classification scheme, quickly and reproducibly. It is not looking at the individuals, and it is not looking at most of either chart.
The eight kūṭas and their weights
The numbers below are the points each factor can contribute, not an ordering. They run 1 through 8 and therefore total 36.
- varṇa (1) — a fourfold grouping of the rāśis, read as temperamental orientation
- vaśya (2) — mutual influence and ascendancy between the signs
- tārā (3) — the count between the two nakshatras, read as well-being
- yoni (4) — the animal symbol assigned to each nakshatra, read as physical and instinctive compatibility
- graha maitrī (5) — friendship or enmity between the lords of the two Moon signs, read as mental rapport
- gaṇa (6) — the deva, manuṣya and rākṣasa classification of the nakshatras, read as disposition
- bhakūṭa (7) — the count between the two Moon rāśis, read as the welfare of the household
- nāḍī (8) — the ādi, madhya and antya grouping, read as constitution and progeny
Where low scores actually come from
Bhakūṭa and nāḍī carry 7 and 8 points, which is 15 of the 36 between them. Each is also scored close to all-or-nothing. A pair that fails both loses well over a third of the total before any of the other six factors is considered, and this is the single commonest reason a match is reported as unacceptable.
The tradition treats both as cancellable. The conditions most often cited for nāḍī doṣa are that the two share a nakshatra but fall in different pādas, or share a rāśi while occupying different nakshatras, or share a nakshatra while occupying different rāśis; bhakūṭa doṣa is commonly held to lapse where graha maitrī is strong or the two Moon lords are the same or friendly. Lineages differ on the details. What matters for a reader is that a “fail” on either factor is a prompt to look further, and that an astrologer who reports one without checking whether it is cancelled has stopped halfway.
Reading the score
The conventional bands are: below 18 discouraged, 18 to 24 acceptable, 25 to 32 good, above 32 very good. Two cautions belong with them.
First, the bands are conventional rather than textual, and practitioners apply them with varying strictness. Second, the total conceals its own composition. A pair scoring 20 with the weak points scattered across small factors is in a different position from a pair scoring 20 because nāḍī and bhakūṭa both failed, and a pair at 28 who fail nāḍī are in a different position again — many astrologers weigh that single factor above the total. The number is a summary, and summaries lose the thing that mattered.
This is not the only Indian system
Aṣṭakūṭa with its 36 points is the North Indian method. Much of South India uses a different scheme, generally counted as ten pōruttam, with an overlapping but not identical set of factors and its own conventions for what constitutes an acceptable match. A couple assessed under both can receive materially different verdicts. The 36-point score is often presented as the traditional method; it is one of the traditional methods, and knowing that is a reasonable defence against being told a single number is the tradition’s final word.
What a full assessment adds
Guṇa milan is the opening move. Beyond it an astrologer examines the 7th house and its lord in both charts, the condition of Venus and Jupiter, Mangal Dosha and whether the conventions that define it are even in agreement, the dignity of the grahas involved, and the daśā periods both people are running — because timing affects a marriage at least as much as compatibility does.
Beyond the points
Guṇa milan compares nakshatra-derived categories. It does not measure affection, character, shared values, financial sense or the willingness of two people to be reasonable with each other, and the tradition never claimed it did. A modest score has never prevented a good marriage, and a high one has never guaranteed one. Used as intended, it is a considered input into a decision that belongs to the people making it. Used as a veto, it is being asked to carry weight it was not built for.

Frequently asked questions
What is a good Guna Milan score?
Out of 36, the conventional bands are 18 or more acceptable, 25 to 32 good and above 32 very good. The bands are conventional rather than textual, and which factors produced the total matters more than the total.
Is Kundali Milan based on the Sun sign?
No. Every one of the eight factors is derived from each person’s Moon nakshatra and the rāśi it falls in. Sun-sign compatibility is a Western convention that classical Jyotisha does not use.
Why did we score badly?
Usually because of bhakūṭa and nāḍī, which carry 7 and 8 points — 15 of the 36 — and are scored close to all-or-nothing. Both are traditionally cancellable, and the cancellation conditions should be checked before any conclusion is drawn.
Does a low score mean we cannot marry?
No. Astrologers weigh the whole picture — the 7th house and its lord, Venus and Jupiter, Mangal Dosha, dignity and the running daśās — and the standard cancellation rules. A low guṇa total on its own is not decisive.
Is the 36-point system used everywhere in India?
No. Aṣṭakūṭa is the North Indian method. Much of South India uses a ten-pōruttam system with a different set of factors and its own conventions, and the two can reach different verdicts on the same couple.
What details are needed for matching?
The exact date, time and place of birth of both partners, so that each Moon position — and from it the nakshatra and rāśi — can be calculated accurately.
