Ashtakoot Guna Milan: What the 36 Points Actually Measure

Guna Milan is the best-known procedure in Indian astrology and the least understood. Families quote scores out of 36 with great confidence and rarely know that the entire calculation rests on one variable per person — the Moon's Nakshatra — or that half the total comes from a single Koot.

Here is what the eight Koots weigh, how the arithmetic works, and where the system's own authorities disagree.

What the inputs are

The Moon's Nakshatra and Rashi for each person. That is all.

Nothing else enters the Ashtakoot calculation. Not the Ascendant, not the seventh house, not the seventh lord, not Venus, not the Dashas. This is worth stating plainly because it explains both the system's convenience — two data points per person — and its limits.

The eight Koots

Note the weighting. Nadi and Bhakoot together are 15 of 36 — more than 40 percent. A couple can be well matched on the six other Koots and still score badly because these two dominate.

Varna (1 point)

Divides the twelve signs into four groups: Brahmin (water signs), Kshatriya (fire), Vaishya (earth), Shudra (air). The point is awarded if the man's Varna equals or exceeds the woman's in a traditional hierarchy.

This is the Koot most obviously carrying assumptions of its period, and it is worth one point out of thirty-six — the system's own weighting treats it as marginal.

Vashya (2 points)

Groups signs by a different scheme — quadruped, human, water-dwelling, insect, wild — and scores mutual influence. It is read as which partner has more natural sway over the other.

Tara (3 points)

Counts the Nakshatra distance between the two Moons in both directions, divides each by nine, and reads the remainder. Remainders of 3, 5 and 7 are inauspicious. Points are awarded according to whether one, both or neither direction lands on a bad remainder.

Yoni (4 points)

Each of the 27 Nakshatras is assigned an animal — horse, elephant, sheep, serpent, dog, cat, rat, cow, buffalo, tiger, deer, monkey, mongoose, lion. Compatibility follows a table of natural relationships between the animals.

Same animal scores the full 4. Natural enemies — cat and rat, serpent and mongoose, cow and tiger, elephant and lion — score 0 or 1. This is read for physical and sexual compatibility.

Graha Maitri (5 points)

Compares the lords of the two Moon signs and scores their natural friendship. Mutual friends score 5, mutual enemies 0, mixed relationships fall between.

This is the Koot most directly about mental and intellectual affinity, and at 5 points it carries real weight. Because it depends on sign lords, two people with Moons in different signs ruled by the same planet — Gemini and Virgo, say, both Mercury — score full marks here automatically.

Gana (6 points)

Sorts the 27 Nakshatras into three temperaments: Deva (divine — gentle, principled), Manushya (human — mixed, practical), Rakshasa (demonic — forceful, self-directed).

Same Gana scores the full 6. Deva with Manushya scores 5 or 6. Deva with Rakshasa scores 0 and is the pairing the texts treat most seriously here.

The names are unhelpful. Rakshasa Gana does not mean a bad person — it describes a forceful, independent, sometimes blunt temperament, and includes Nakshatras associated with considerable achievement.

Bhakoot (7 points)

Counts the distance between the two Moon signs in both directions. Certain relationships score zero outright:

Everything else scores the full 7. Bhakoot is therefore all-or-nothing: seven points or zero, with no middle. A single unlucky sign relationship removes nearly a fifth of the total score.

Nadi (8 points)

The largest single Koot. Each Nakshatra is assigned one of three Nadis — Aadi, Madhya, Antya — loosely corresponding to the Ayurvedic constitutional types Vata, Pitta and Kapha.

Different Nadi scores the full 8. Same Nadi scores 0.

There is no partial credit. Nadi Dosha is the single most common reason a match fails, and because it is 8 points, a same-Nadi couple starts from a maximum possible score of 28.

The traditional reasoning is genetic — that constitutionally similar parents produce weaker progeny. Whether one accepts that reasoning or not, it is the stated basis.

How the score is read

18 is the conventional minimum. In practice most astrologers treat anything above 21 as workable and anything below 18 as requiring the rest of the chart to make the case.

The exceptions

The texts list conditions under which Nadi and Bhakoot Dosha do not apply. These are routinely omitted from automated reports.

Nadi Dosha is cancelled if:

Bhakoot Dosha is cancelled if:

These exceptions are common enough in practice that a raw score reported without checking them is frequently misleading. Our matching tool applies them and reports which cancellation fired.

What the system does not check

This is the honest part, and it matters more than the score.

Ashtakoot uses two data points per person. It does not look at:

A high Guna score with a badly afflicted seventh house in both charts is not a good match, and a low score with strong seventh houses and a supportive Navamsa is frequently a workable one. Competent practitioners treat the 36 points as a first filter, not a verdict.

An honest closing note

Guna Milan was designed for arranged marriages between families who did not know each other, as a screening tool. It is very good at that job and it was never intended to be the last word.

If two people who know each other well are given a score of 19 and take it as a reason not to marry, the system is being asked to do something it was not built for. The scores are a starting point for a conversation with someone who can read both charts properly — not a result to act on directly.

Run a match

The Kundali matching tool computes all eight Koots from both Moon positions, applies the classical cancellation conditions, and reports which Koot lost points and why — rather than only a total out of 36.
