Before most traditional Indian weddings, an astrologer runs Ashtakoot Milan and returns with a number out of 36. But what does that number actually measure? Here's the full breakdown — including what it misses.
Before almost every traditional Indian wedding, two Kundalis go to an astrologer. The astrologer runs the Ashtakoot Milan and comes back with a number out of 36. The family nods, discusses, and — depending on the score — either celebrates or reconsiders.
Most people who go through this process — whose marriages may partly depend on it — have never been told what the 8 categories are, why they're weighted the way they are, or what the score actually means in practice. Here's the complete explanation.
The Foundation: Why Everything Comes from the Moon
"Ashta" means eight. "Koota" means category or compatibility dimension. The entire Ashtakoot system calculates compatibility from the Moon's Nakshatra (lunar mansion) of each person — not the Sun sign, not the Ascendant.
This reflects Vedic astrology's core belief about marriage: it's fundamentally an emotional, psychological, and biological partnership. The Moon governs your mind, emotional instincts, daily behavioral rhythms, and inner world — exactly what you're actually living with in a marriage, day after day. The Sun sign tells you who someone is in the world. The Moon's Nakshatra tells you who they are at home.
The 8 Kootas Explained
Varna (1 point) — spiritual and ego-level alignment. Checks whether both partners are at a similar level of personal and spiritual development. Carries the least weight because this type of friction is the easiest to consciously overcome with growth and communication.
Vashya (2 points) — mutual attraction and power dynamics. Which partner has natural influence over the other? Healthy Vashya indicates mutual respect and gravitational attraction, not dominance over someone who can't say no.
Tara (3 points) — auspiciousness and wellbeing. Checks whether the partners' Nakshatras are in favorable positions relative to each other — essentially whether being together is fortunate for both people's health and longevity, not just emotionally but energetically.
Yoni (4 points) — physical and intimate behavioral compatibility. Each Nakshatra is assigned an animal symbol. Yoni checks how compatible those energies are in terms of physical chemistry and instinctive behavioral rhythms when two people are close.
Grah Maitri (5 points) — intellectual and emotional friendship. Checks whether the planetary lords of each partner's Moon sign are friendly, neutral, or hostile to each other in classical planetary relationships. Strong Grah Maitri means natural rapport and shared values — the foundation of good friendship, which is what sustains most long marriages after the initial chemistry fades.
Gana (6 points) — temperament compatibility. Each Nakshatra belongs to one of three Ganas: Deva (gentle, idealistic), Manushya (balanced, pragmatic), or Rakshasa (intense, fierce). Matches within the same Gana score highest. Deva-Rakshasa mismatches score zero — not because the relationship can't work, but because the behavioral friction is structural and requires continuous conscious effort rather than something that resolves naturally over time.
Bhakoot (7 points) — emotional bonding and shared prosperity. Checks the relative position of each partner's Moon sign from the other's. The second-highest weighted factor — certain Bhakoot combinations are associated with financial difficulties or reduced family harmony, and because these effects are material rather than personal, they're harder to address through individual effort alone.
Nadi (8 points) — genetic and constitutional compatibility. The highest-weighted factor. Each Nakshatra belongs to one of three Nadis (Adi, Madhya, Antya). Matching Nadi creates Nadi Dosha — the most feared result in Ashtakoot, associated with potential health complications or challenges with children. Classical texts provide specific cancellation conditions: if both partners share the same Moon Nakshatra, or both are in the same Rashi, the Dosha is considered cancelled. Most charts flagged for Nadi Dosha have at least one cancellation present. Always check before concluding anything.
What the Score Actually Means
Below 18 signals significant incompatibility across multiple dimensions. 18-24 is workable — most actual marriages in practice fall in this range. 24-32 reflects natural harmony across most categories. Above 32 is rare and considered highly auspicious, though some classical practitioners note that very high scores can indicate charts that are too similar, reducing the complementary dynamic that makes partnerships energizing.
The total alone is incomplete information. A score of 22 with active Nadi Dosha is categorically different from a score of 22 where Nadi is cancelled. A 30 with an active high-weight dosha needs specific examination. Always read the breakdown, not just the number.
What Ashtakoot Doesn't Cover
The 36-point system deliberately measures only Moon-based compatibility. It does not assess Mangal Dosha, the condition of each partner's 7th house (the primary house of marriage), Dasha compatibility (whether both people are in life phases that support commitment), Venus's condition in each chart, or Jupiter's placement. A complete Kundali matching analysis uses Ashtakoot as a starting foundation and adds these dimensions. Our Kundali Matching tool covers the full picture.
The system was never designed as a binary pass/fail verdict. It's a compatibility map — here's where you naturally align, here's where friction is likely, here's what will need conscious attention. Use it that way.
