Ashtakoot Guna Milan —
the 36-point system

Ashtakoot Guna Milan — described in the Prasna Marga and expanded in classical matching texts — assesses eight areas of compatibility between two people's Moon nakshatras and rashis. Each area has a maximum score; the total is out of 36. The Steer app computes all eight kutas, shows where a pair is strong and where they should be aware, and explains what each kuta measures.
Guidance from
both charts together

Compatibility scores tell part of the story. The Steer app's AI astrologer can look at two charts together — comparing 7th house lords, Venus placements, relationship yogas in both D-1 and D-9 — and give guidance on how two people are likely to experience being together, where tensions may arise, and which periods ahead are favorable for the relationship.
What each kuta measures
Ashtakoot (eight-point) Guna Milan assesses eight distinct areas of compatibility between two people's nakshatra placements. Together these total 36 points.
Varna — 1 point
Spiritual compatibility and harmony between the two individuals' work orientation and values. The foundation of mutual respect.
Vashya — 2 points
Mutual influence and attraction. Whether the two natures naturally draw toward each other or require effort to connect.
Tara — 3 points
Longevity and wellbeing of the relationship over time, based on the distance between the two Moon nakshatras.
Yoni — 4 points
Physical and intimate compatibility. Each nakshatra corresponds to an animal symbol; compatible pairs score more highly on this kuta.
Graha Maitri — 5 points
Intellectual and emotional compatibility based on the friendship between the lords of the two Moon signs. The most points in the system.
Gana — 6 points
Temperamental compatibility. Nakshatras are grouped as Deva (divine), Manava (human), and Rakshasa (fierce). Matched ganas score maximum points.
Rashi — 7 points
Compatibility based on the relationship between the two Moon signs and their ruling planets. Scores the general harmony of the partnership.
Nadi — 8 points
Health and progeny compatibility. The single highest-valued kuta. Same-nadi matches score 0 and are traditionally considered a concern requiring attention.
