How Many Gunas Should Match for Marriage — and What If It's Under 18?

In Ashtakoota Guna Milan you are scored out of 36 gunas, and the traditional minimum considered acceptable is 18. But the headline number is the least important part: which of the eight kootas matched — and whether Nadi or Bhakoot dosha is present — tells you far more than "we got 28."

The 36 gunas, and what 18 means

Guna Milan compares the two Moon positions across eight kootas (factors), weighted to total 36 points: Varna (1), Vashya (2), Tara (3), Yoni (4), Graha Maitri (5), Gana (6), Bhakoot (7), and Nadi (8). As a rough traditional reading:

• Below 18 — not conventionally recommended on score alone.
• 18–24 — acceptable / average.
• 25–32 — very good.
• 33–36 — excellent (and a perfect 36 is rare).

Notice that Nadi alone carries 8 points and Bhakoot 7 — together nearly half the total. That is the key to reading a score properly.

What if it's under 18?

A score under 18 is a prompt to look closer, not an automatic "no":

• See which points were lost. Losing easy low-weight kootas (Varna, Vashya) is very different from failing Nadi or Bhakoot. The quality of the shortfall matters.
• Check for dosha and for its cancellation. A low score driven by Nadi or Bhakoot dosha is the real concern; but both have traditional exceptions that can cancel them. See Nadi dosha and Bhakoot dosha cancellation.
• Remember Guna Milan is one layer. Classical matching also weighs both 7th houses, Mars (Manglik) compatibility, and the dasha periods — a chart-level reading, not just the koota tally.

So "under 18" sometimes reflects a couple of minor mismatches with no dosha at all — workable — and sometimes a Nadi dosha that needs a proper check.

What about a very high score?

A high score is reassuring but not the whole story either; the Brihat Parashara Hora Shastra and the matchmaking tradition treat Guna Milan as a screening layer, after which the full charts are compared. A 32/36 with an unaddressed dosha still deserves scrutiny.

Run a real match

A meaningful score needs both partners' real Moon nakshatras, which come from date + time + place — not a name (see kundli by name vs date of birth). Match both charts with the calculator below to see the koota-by-koota breakdown, not just the total.

FAQ

Is 18 a hard cutoff?

It's the conventional minimum, not a law. A 17 with only minor kootas missing and no dosha can be perfectly workable; a 20 carrying Nadi dosha may warrant more care. Read the breakdown.

Which koota is the most important?

Nadi (8 points) and Bhakoot (7 points) carry the most weight and the most significant doshas, so they dominate both the score and the interpretation.

Is a 36/36 the best possible match?

It's the maximum, and rare but astrologers still examine the full charts. The score screens compatibility; it doesn't replace a chart reading.
