The 36-point answer
Kundli matching, or guna milan, compares two birth charts using the Ashtakoota system: eight kootas (compatibility factors) worth 1 to 8 points each, totalling 36. Each koota is scored from the two partners' Moon signs and janma nakshatras. Traditionally, 18 or more points is considered an acceptable match, with higher totals indicating stronger natural alignment.
The word Ashtakoota literally means 'eight categories'. Every point in the final score traces to one of these eight comparisons — there is nothing hidden in the total, which is why two correctly computed reports from any source should agree exactly.
The eight kootas and what each measures
The kootas are weighted by how central classical astrologers considered each dimension, from 1 point up to 8. In order of weight:
- Varna (1 point) — temperamental class and ego compatibility, from the Moon sign
- Vashya (2 points) — mutual influence and adaptability between the two Moon signs
- Tara (3 points) — birth-star compatibility, counted between the two nakshatras, read as shared wellbeing and fortune
- Yoni (4 points) — instinctive and physical compatibility, from the animal symbol assigned to each nakshatra
- Graha Maitri (5 points) — friendship between the lords of the two Moon signs, read as mental rapport and shared outlook
- Gana (6 points) — temperament type (deva, manushya, or rakshasa nakshatra groups), read as behavioural compatibility
- Bhakoot (7 points) — the distance between the two Moon signs, read as emotional harmony and the practical rhythm of shared life
- Nadi (8 points) — the nakshatra's nadi group (adi, madhya, or antya), traditionally linked to health and progeny; the heaviest-weighted koota
How the score is computed
Everything starts from two accurately cast charts. Each partner's birth date, time, and place fixes the Moon's sidereal position; on MyAstro360 that computation uses the Swiss Ephemeris with the Lahiri (Chitrapaksha) ayanamsa — the standard reference of Indian panchangs. The process is deterministic: the same inputs always produce the same chart and the same score.
From the Moon's degree, each person gets a Moon sign (rashi) and a janma nakshatra. The eight kootas are then scored one by one from classical lookup tables — for example, Gana compares which of the three temperament groups each nakshatra belongs to, while Bhakoot counts the sign distance between the two Moons. Each koota awards between zero and its maximum, and the eight results are summed to a total out of 36.
Because the whole system reads only the two Moon positions, kundli matching does not require the full charts to agree on everything else — which is also its main limitation, discussed below.
Reading the score without fear
The traditional thresholds: below 18 points is classically considered weak, 18 to 24 acceptable, 25 to 32 very good, and 33 to 36 excellent. But the total alone is an incomplete reading. Astrologers pay close attention to which kootas scored zero — Nadi dosha (0 in Nadi) and Bhakoot dosha (0 in Bhakoot) are traditionally weighted more seriously than a modest total spread evenly across categories, and classical texts also describe specific cancellations for both.
A low score is an indicator to discuss, not a verdict on a relationship. It flags specific dimensions — temperament, mental rapport, emotional rhythm — where the two Moon placements differ, so a couple or their families know what to look at more carefully. Many practitioners follow up a low guna count by examining the full charts: the seventh house, Venus, the navamsa, and any manglik considerations on both sides.
Honest limits of guna milan
Ashtakoota is an interpretive tradition, not a measured fact about two people. It reads exactly two data points — the Moon positions at each birth — and says nothing about shared values, communication, or circumstance. Treat the score as a structured conversation starter grounded in a specific classical method, alongside everything else you know about each other.
It is also worth knowing that guna milan is the North Indian convention; South Indian traditions use a related but different set of porutham factors. Neither is more 'correct' — they are different classical lenses on the same two charts.
