Your guna milan score: what a high or low number actually means

Guna milan (Ashtakoot matching) reduces two birth charts to a single number out of 36 — which is convenient, and also the reason it gets misread more than almost any other part of Vedic astrology. A number invites a threshold: “18 or above is fine, below is a problem.” The tradition itself is more specific than that.

What's actually being scored

Ashtakoot checks eight separate factors (koots) between two charts — primarily based on each person's Moon nakshatra — and each carries a different maximum weight because they're not considered equally important:

• Varna (1 point) — spiritual/psychological compatibility
• Vashya (2 points) — mutual influence and control in the relationship
• Tara (3 points) — general wellbeing and health compatibility
• Yoni (4 points) — physical and sexual compatibility
• Graha Maitri (5 points) — mental compatibility, friendship between the Moon lords
• Gana (6 points) — temperament compatibility
• Bhakoot (7 points) — overall fortune and relationship longevity
• Nadi (8 points) — health of offspring and genetic compatibility

Notice that Nadi alone is worth almost a quarter of the entire score. This is exactly why a flat total misleads more than it informs: two couples can land on the identical overall number while scoring it in completely different places, and those are not equivalent situations.

Why Nadi and Bhakoot get special treatment

Classical texts don't just weight these two koots heavily — they treat a zero score on either as worth a second look even when the total elsewhere is strong, because Nadi speaks to long-term health compatibility and Bhakoot to the relationship's overall stability. But — and this is the part a bare number never shows — both Nadi Dosha and Bhakoot Dosha have recognised classical cancellations: specific chart conditions (such as both partners sharing the same nakshatra but a different pada, or particular lordship relationships between the Moon signs) under which the dosha is considered void. A calculator that reports “Nadi Dosha: yes” without checking for these is doing the same incomplete job as a Mangal Dosha check that skips the cancellation rules.

How to actually read your number

Rather than asking “did we pass,” it's worth asking three narrower questions: is there a Nadi or Bhakoot dosha, and if so is it cancelled; how did the Mangal Dosha status compare on both sides (see our note on that here); and where does the bulk of the score actually come from. A 24/36 built mostly on the smaller koots with a clean Nadi and Bhakoot reading is a different picture from a 24/36 that only reached that total because Nadi and Bhakoot maxed out while everything else was weak. The number is a starting point for a conversation with an astrologer, not a verdict to accept or reject on its own.
