Kundali Milan Explained: The 36 Gun Ashtakoot System
Kundali Milan is the Vedic process of matching two birth charts before marriage. In Nepal and across the Hindu world, families use it to judge how well a prospective bride and groom suit each other. The most common method is the Ashtakoot system, which scores compatibility out of 36 points.
The word ashtakoot means "eight factors" (ashta = eight, koot = category). Each factor, called a koota or guna, tests one dimension of compatibility, from temperament to health and progeny. The points are added up to give a single score that astrologers and families read at a glance.
This guide explains all eight kootas, how the 36 points are split, what the score bands mean, and how the two big doshas, Nadi and Bhakoot, can affect a match.
What is Kundali Milan and why does it matter?
Kundali Milan, also called Gun Milan or Ashtakoot Milan, compares the Moon's position in two birth charts to score marital compatibility out of 36 points. It looks at temperament, health, family harmony, and progeny. A higher score suggests a more harmonious match in traditional Vedic assessment.
The method rests almost entirely on the Moon sign (Rashi) and birth star (Nakshatra) of each person, not the Sun sign used in Western astrology. Because of this, accurate birth details, date, exact time, and place, matter a great deal. A small error in birth time can shift the Nakshatra and change the result.
If you are new to Rashi, our explainer on the 12 Rashi and their traits is a useful starting point, since every koota is built on the Moon Rashi of the two charts.
What are the 8 kootas and their points?
The Ashtakoot system splits 36 points across eight kootas, weighted by importance. Varna carries 1 point and Nadi carries 8, the maximum. Each koota tests a different layer of compatibility, so the eight scores together build a full picture rather than a single yes-or-no verdict.
| Koota | Max Points | What It Tests |
|---|---|---|
| Varna | 1 | Spiritual compatibility and ego balance between the couple |
| Vashya | 2 | Mutual attraction, influence, and who leads in the relationship |
| Tara | 3 | Health, well-being, and overall destiny (birth-star compatibility) |
| Yoni | 4 | Physical and sexual compatibility, intimacy, and instincts |
| Graha Maitri | 5 | Mental compatibility, friendship, and intellectual bonding |
| Gana | 6 | Temperament and nature (Deva, Manushya, or Rakshasa type) |
| Bhakoot | 7 | Family welfare, love, and long-term prosperity together |
| Nadi | 8 | Health, genes, and progeny (the most heavily weighted factor) |
Notice the points run 1, 2, 3, 4, 5, 6, 7, 8, which add up to exactly 36. This ascending weight reflects tradition: factors tied to health and children (Nadi, Bhakoot) carry more weight than surface-level ones (Varna, Vashya).
The three most important kootas
Among the eight, Nadi, Bhakoot, and Gana draw the most attention. Nadi alone is worth 8 points and is linked to genetic health and childbearing. Bhakoot governs family prosperity, and Gana measures basic temperament. A match that scores well on these three is generally considered strong.
How are the 36 Gun scores interpreted?
Most astrologers treat 18 points as the minimum acceptable threshold for marriage. Below 18 is usually discouraged, 18 to 24 is considered acceptable, 25 to 32 is very good, and 33 to 36 is rare and excellent. The score is a guide, not an absolute verdict on a relationship.
Here is how the bands are commonly read in practice:
Below 18: Considered a weak match in traditional terms; many families hesitate or seek remedies.
18 to 24: Acceptable. The most common range for approved marriages.
25 to 32: A very good, harmonious match.
33 to 36: Excellent and uncommon; an ideal pairing on paper.
One important caveat: the raw score can be misleading on its own. An astrologer always reads the doshas (defects) alongside the total. A couple can score above 18 yet still carry a Nadi or Bhakoot dosha that needs review, so the headline number is never the whole story.
What are Nadi dosha and Bhakoot dosha?
Nadi dosha occurs when both partners share the same Nadi, scoring 0 of 8 points. Because Nadi is tied to health and progeny, it is treated as a serious flaw. Bhakoot dosha arises from certain unfavorable Rashi distances and affects family harmony, scoring 0 of 7 points when present.
Nadi dosha
There are three Nadis: Aadi, Madhya, and Antya. If the bride and groom fall in the same Nadi, the koota scores zero, and this is called Nadi dosha. Classical texts link it to health and childbearing concerns. However, several cancellation (parihar) rules exist, for example when both share the same Rashi but different Nakshatras, which can neutralize the defect.
Bhakoot dosha
Bhakoot dosha appears when the two Moon Rashis sit at specific distances, commonly the 6-8 (Shadashtak) or 2-12 (Dwirdwadash) positions. It is associated with financial strain or family discord. Like Nadi, Bhakoot dosha has cancellation conditions, such as a friendly planetary relationship between the two Rashi lords.
Doshas are not the only marriage check Nepali families run. A separate concern is Mangal Dosha, which our guide on what Manglik dosha means and its remedies covers in detail. Many families review both Ashtakoot and Manglik status together.
How does the Nepali Calendar (Katigate) app compute Kundali Milan?
The Nepali Calendar (Katigate) app calculates the full Ashtakoot Milan automatically from two sets of birth details. You enter each person's date, time, and place of birth, and the app derives the Moon Rashi and Nakshatra, scores all eight kootas, totals the 36 points, and flags any Nadi, Bhakoot, or Mangal dosha along with applicable cancellation rules.
This removes the manual table lookups that traditional matching required. The result shows each koota's individual score, the grand total, a plain-language verdict, and the dosha summary for both partners. You can save results and revisit them later.

Frequently Asked Questions
Is a score below 18 a definite no for marriage?
Not necessarily. Below 18 is traditionally discouraged, but the total alone never decides a match. Astrologers weigh the doshas, their cancellation rules, and the wider chart. Many couples with lower scores marry happily, while compatibility in real life depends on far more than the Ashtakoot number.
What is the most important koota in the 36 Gun system?
Nadi is the most heavily weighted koota at 8 of 36 points, because it relates to health, genes, and progeny. Bhakoot (7 points) and Gana (6 points) follow closely. Together these three carry 21 of the 36 points, so they dominate the overall compatibility verdict.
Can Kundali Milan use the Sun sign instead of the Moon sign?
No. The Ashtakoot system is built on the Moon Rashi and birth Nakshatra, not the Sun sign used in Western horoscopes. This is why exact birth time matters. For daily Moon-based forecasts, see our explainer on what Rashifal is and how it works.
Does a high Ashtakoot score guarantee a happy marriage?
No. A high score, even 33 to 36, indicates strong traditional compatibility but cannot guarantee a happy marriage. Vedic matching is one input among many. Communication, values, family support, and individual choices shape a relationship far more than any single compatibility score on paper.
