Everything rests on the Moon
All eight kootas are computed from the Moon's sign and nakshatra in each chart. Nothing else — not the ascendant, not Venus, not the 7th house — enters the 36 points.
That is why an accurate birth time matters less here than for a full chart reading, but also why a high score alone is a narrow verdict. Experienced astrologers read Gun Milan alongside the 7th house, its lord, and the condition of Venus and Jupiter.
How the score is usually read
Below 18 is conventionally regarded as insufficient; 18 to 24 acceptable; 25 to 32 good; and above 32 excellent. Very few real pairings score a perfect 36. Half points occur legitimately — Graha Maitri awards 0.5 where one lord is an enemy and the other neutral — so a total of 28.5 is normal, not a rounding error.
Nadi and Bhakoot carry the most weight
Nadi alone is worth 8 points and Bhakoot 7, so together they are nearly half the total. A Nadi dosha, where both partners share the same nadi, is the most commonly cited objection in traditional matching, and classical texts describe several conditions under which it is considered cancelled.
Mangal Dosha
Mangal (or Kuja) dosha is assessed separately from the 36 points. It arises when Mars occupies the 1st, 2nd, 4th, 7th, 8th or 12th house, counted from the ascendant, the Moon or Venus depending on the tradition followed.
Classical practice holds that the dosha is neutralised when both partners have it, and several other cancellations are recognised. It is a factor to weigh, not a verdict.
What the score cannot tell you
Gun Milan says nothing about whether two people communicate well, share values, or want the same life. It is one traditional input among many, and it should never be the sole basis for a decision about a relationship.
Regional differences
Ashtakoota is the northern method. In much of southern India, Dashakoota — a ten-factor system — is preferred, and its weightings differ. Neither is more correct; they are different regional traditions, and a match may score differently under each.
