Nakshatra Compatibility — Ashtakoota Matching Guide
Complete guide to the 8-Koota (Guna Milan) system for Hindu marriage compatibility
What is Ashtakoota Matching?
Ashtakoota (Ashta = eight, Koota = category) is the traditional Vedic system for assessing marriage compatibility based on the birth Nakshatras of the bride and groom. Also known as Guna Milan, it evaluates 8 different aspects of compatibility and assigns a score out of 36 points.
The system uses the Moon's Nakshatra at birth (Janma Nakshatra) for both partners. To find your birth Nakshatra, you need your exact birth date, time, and location. Use our Nakshatra Finder to determine yours.

1. Varna Koota (1 point)
Spiritual compatibility
Compares the spiritual or ego level of the couple. The four Varnas (Brahmin, Kshatriya, Vaishya, Shudra) are assigned to Nakshatras. If the groom's Varna is equal to or higher than the bride's, full points are given.
Interpretation: Determines the couple's spiritual and intellectual compatibility. Mismatch may indicate ego clashes.
2. Vashya Koota (2 points)
Mutual attraction & dominance
Assesses the mutual control and attraction between partners. Five categories: Chatushpada (quadruped), Manava (human), Jalachara (water creature), Vanachara (wild), and Keeta (insect). Some categories naturally attract or dominate others.
Interpretation: Higher score indicates natural attraction and willingness to adjust. Low score may mean power struggles in the relationship.
3. Tara Koota (3 points)
Destiny & luck compatibility
Calculated by counting Nakshatras from bride to groom and vice versa, then dividing by 9. The remainder determines compatibility. Certain remainders (3, 5, 7 — Vipat, Pratyari, Vadha) are inauspicious.
Interpretation: Ensures the couple's destiny patterns are harmonious. Good Tara score indicates mutual luck and fortune enhancement.
4. Yoni Koota (4 points)
Physical & sexual compatibility
Each Nakshatra is assigned a Yoni (animal symbol) — there are 14 animal pairs. Same Yoni gives full points, friendly animals give partial points, and enemy animals give zero. This koota assesses physical and intimate compatibility.
Interpretation: Critical for marital harmony. Low Yoni score may indicate physical incompatibility or dissatisfaction.
5. Graha Maitri Koota (5 points)
Mental & intellectual compatibility
Compares the Moon sign (Rashi) lords of both partners. If the lords are friends, full points; neutral gives partial; enemies give zero. Based on the natural friendship table of the 9 planets.
Interpretation: Determines mental wavelength alignment. High score means the couple thinks similarly and resolves conflicts effectively.
6. Gana Koota (6 points)
Temperament & nature matching
Each Nakshatra belongs to one of three Ganas: Deva (divine — gentle, cultured), Manushya (human — balanced, practical), or Rakshasa (demon — assertive, independent). Same Gana is best; Deva-Rakshasa combination is least compatible.
Interpretation: Major factor in daily compatibility. Mismatched Gana can lead to frequent arguments and lifestyle conflicts. However, Rakshasa Gana individuals are not "bad" — they are simply more independent and assertive.
7. Bhakoot Koota (7 points)
Love, family & financial compatibility
Based on the relative positions of Moon signs (Rashis). Certain combinations are Bhakoot Doshas — 2/12 (financial loss), 6/8 (health/conflict), and 5/9 (progeny issues). These give 0 points. All other combinations score full 7.
Interpretation: Highest weight among the 8 Kootas. Bhakoot Dosha can indicate significant challenges in the marriage, but is often mitigated by other factors like Nadi score.
8. Nadi Koota (8 points)
Health & genetic compatibility
Each Nakshatra is assigned one of three Nadis: Aadi (Vata), Madhya (Pitta), or Antya (Kapha). Same Nadi gives 0 points (Nadi Dosha), different Nadis give full 8 points. Nadi Dosha is considered the most serious defect.
Interpretation: Critical for health and progeny. Same Nadi (Nadi Dosha) traditionally indicates health issues for children and genetic incompatibility. However, certain Nakshatra combinations are exceptions to Nadi Dosha.
Score Interpretation
| Score Range | Rating | Description |
|---|---|---|
| 0–17 | Not Recommended | Below acceptable threshold. Marriage is generally not recommended unless other strong mitigating factors exist (same Rashi, Nadi exceptions, etc.). |
| 18–23 | Acceptable | Minimum acceptable score. The marriage can proceed but may face challenges. Remedial pujas may be recommended. |
| 24–29 | Good | Good compatibility. The couple is well-matched in most aspects. Minor issues can be managed with understanding. |
| 30–36 | Excellent | Excellent compatibility. Highly harmonious match across all dimensions — spiritual, physical, mental, and emotional. |
Important Doshas (Defects) to Watch
Nadi Dosha (0 in Nadi Koota)
Considered the most serious defect. Occurs when both partners have the same Nadi. Traditionally associated with health issues and difficulty in having children. Remedies include Nadi Dosha Nivarana Puja and specific charitable donations.
Bhakoot Dosha (0 in Bhakoot Koota)
Occurs in 6/8 (conflict), 2/12 (financial loss), or 5/9 (progeny issues) Moon sign combinations. Considered significant as Bhakoot carries 7 points. Can sometimes be cancelled if Nadi scores full 8 points.
Gana Dosha (0 in Gana Koota)
Deva-Rakshasa combination scores 0. Indicates very different temperaments and lifestyles. Less serious than Nadi or Bhakoot Dosha and can be managed with mutual understanding and effort.

Frequently Asked Questions
What is the minimum score required for marriage?
The traditional minimum is 18 out of 36 points (50%). Scores of 24+ are considered good and 30+ are excellent. However, the total score alone is not sufficient — certain individual Kootas carry more weight. For example, a score of 20 with Nadi Dosha (0 in Nadi) is considered worse than a score of 18 without any Dosha.
Is Kundli matching the same as Nakshatra matching?
Nakshatra matching (Ashtakoota / Guna Milan) is one component of Kundli matching, but not the entirety. Full Kundli matching also examines: Mangal Dosha (Mars placement), planetary aspects, Dasha compatibility, house positions, and overall chart strength. Ashtakoota scoring is the initial screening, after which a detailed Kundli analysis is recommended.
Can marriage succeed with a low Guna Milan score?
Yes. Many successful marriages have low Guna Milan scores, and some high-scoring matches face difficulties. Guna Milan is a traditional guideline, not a guarantee. Factors like mutual respect, communication, shared values, family support, and individual maturity play a far larger role in marital success. Astrologers often recommend remedial pujas for specific Doshas rather than rejecting a match outright.
