What Is Ashtakoot?
Ashtakoot (ashta = eight, koota = factor) is the eight-factor compatibility scoring system used in Vedic astrology to assess the Moon-level compatibility between two people. It is the foundation of traditional Kundli matching — both people's Moon nakshatras are compared across eight dimensions, each assigned a specific maximum point value, producing a total score out of 36 gunas.
Each koota measures a genuinely distinct dimension of compatibility — not redundant variations on the same theme, but eight different aspects of how two people's fundamental natures interact. Understanding what each factor actually measures — beyond the names — makes your Compatibility Score interpretable rather than just a number.
The Eight Kootas, Explained
1. Varna Koota — 1 Point
What it measures: Spiritual compatibility and evolutionary alignment.
In traditional classification, the 27 nakshatras are divided into four varna categories corresponding to the four dharmic stages: Brahmin (highest — spiritual and intellectual), Kshatriya (warrior, protective), Vaishya (merchant, prosperity-oriented), and Shudra (service-oriented).
How points are awarded: The man's varna must be equal to or higher than the woman's varna for the full 1 point. If the woman's varna is higher, 0 points are awarded.
In practice: This factor carries the lowest weight (1 point) and in contemporary relationships, its significance is largely symbolic — it originally related to caste and social structure. Most modern Vedic astrologers treat it as an indicator of whether both people are at compatible stages of spiritual or values development. Misalignment here (0 points) has minimal practical impact given its low weighting.
Score interpretation: 0 or 1 point. A 0 here with a high overall score is not concerning.
2. Vashya Koota — 2 Points
What it measures: Natural attraction, influence, and the dynamic of mutual draw.
Vashya means "control" or "influence" — but in the relational context, it refers to which Moon signs naturally draw or are drawn to others. The 12 Moon signs are classified into five groups (human, quadruped, water, wild animal, insect), and specific group relationships are considered vashya (naturally attractive to each other).
How points are awarded: If both Moon signs are vashya to each other, full 2 points. If one is vashya to the other, 1 point. If neither, 0 points.
In practice: This factor measures the natural magnetic draw and comfort in the relationship. High Vashya Koota indicates the two people naturally gravitate toward each other — there is ease of attraction and a sense of natural fit. Low Vashya suggests the attraction requires more conscious effort to sustain.
Score interpretation: 0–2 points. 2 is excellent; 1 is acceptable; 0 indicates limited natural draw.
3. Tara Koota — 3 Points
What it measures: Health, wellbeing, and long-term fortune compatibility.
Tara means "star" — this factor counts the nakshatra distance from one person's birth nakshatra to the partner's birth nakshatra and divides by nine. The remainder determines the tara (birth star compatibility) of that direction. This calculation is done in both directions (Person A to Person B, and B to A) and both must produce auspicious taras for full points.
The nine taras have specific qualities: Janma, Sampat (wealth), Vipat (danger), Kshema (wellbeing), Pratyari (obstacles), Shatru (enemy), Vadha (harmful), Mitra (friend), Atimitra (great friend). Auspicious taras (Sampat, Kshema, Mitra, Atimitra) produce points; inauspicious taras (Vipat, Pratyari, Shatru, Vadha) reduce points.
How points are awarded: Full 3 points if both directions produce auspicious taras; partial points if one direction is auspicious; 0 if both directions produce inauspicious taras.
In practice: This is a health and prosperity compatibility factor. High Tara Koota suggests the relationship is conducive to the physical wellbeing and overall fortune of both people. Low Tara suggests the relationship may be accompanied by health challenges or fortune fluctuations for one or both partners.
Score interpretation: 0–3 points. 3 is excellent; 1.5 is acceptable; 0 is a meaningful flag.
4. Yoni Koota — 4 Points
What it measures: Physical, sensual, and intimate compatibility.
Each of the 27 nakshatras is assigned an animal symbol (yoni) — horse, elephant, sheep, serpent, dog, cat, rat, cow, buffalo, tiger, deer, monkey, lion, or mongoose. The 14 animals are paired into male-female pairs, and each pairing is classified as either friendly, neutral, or enemy.
How points are awarded: Same yoni (perfectly matched pair) = 4 points. Friendly yoni = 3 points. Neutral yoni = 2 points. Enemy yoni = 1 point. Extremely hostile yoni (specific pairs) = 0 points.
In practice: Yoni Koota is the physical and intimate compatibility factor — it measures the natural resonance (or friction) in the physical dimension of the relationship. High Yoni Koota (3–4) indicates natural physical compatibility and a comfortable intimate dynamic. Low Yoni (0–1) suggests the physical and sensual dimensions of the relationship require more conscious effort and communication.
Score interpretation: 0–4 points. 3–4 is excellent; 2 is moderate; 0–1 is a significant consideration for intimate relationships.
5. Graha Maitri Koota — 5 Points
What it measures: Mental compatibility and intellectual resonance.
Graha Maitri means "planetary friendship." This factor examines the natural relationship between the lords of both people's Moon signs. If the two Moon sign lords are natural friends, the two minds naturally understand each other. If they are neutral, understanding requires effort. If they are enemies, the two minds approach life from fundamentally different cognitive orientations that create persistent misunderstanding.
How points are awarded: Both lords are mutual friends = 5 points. One friend, one neutral = 4 points. Both neutral = 3 points. One friend, one enemy = 2 points. Both neutral and one enemy = 1 point. Both enemies = 0 points.
In practice: This is the mental compatibility factor — how naturally the two people's minds work together. High Graha Maitri indicates the two people think similarly, understand each other's reasoning, and find intellectual engagement natural and comfortable. Low Graha Maitri indicates persistent cognitive friction — the two people approach problems, make decisions, and process information in fundamentally different ways that require conscious bridging.
Score interpretation: 0–5 points. 4–5 is excellent; 3 is adequate; 0–2 is a meaningful consideration — these relationships work but require active effort to bridge cognitive differences.
6. Gana Koota — 6 Points
What it measures: Temperamental and dispositional compatibility.
Each nakshatra belongs to one of three ganas — fundamental temperamental categories:
Deva Gana (Divine temperament): Gentle, refined, spiritually oriented, peace-loving. Nakshatras: Ashwini, Mrigashira, Punarvasu, Pushya, Hasta, Swati, Anuradha, Shravana, Revati.
Manushya Gana (Human temperament): Moderate, balanced, practically oriented, able to navigate both gentleness and intensity. Nakshatras: Bharani, Rohini, Ardra, Purva Phalguni, Uttara Phalguni, Purva Ashadha, Uttara Ashadha, Purva Bhadrapada, Uttara Bhadrapada.
Rakshasa Gana (Intense temperament): Forceful, intense, passionate, willing to engage with difficult and dark dimensions of experience. Nakshatras: Krittika, Ashlesha, Magha, Chitra, Vishakha, Jyeshtha, Mula, Dhanishtha, Shatabhisha.
How points are awarded: Same gana = 6 points. Deva-Manushya or Manushya-Deva = 5 points. Deva-Rakshasa or Rakshasa-Deva = 0 points. Manushya-Rakshasa or Rakshasa-Manushya = 0 points.
In practice: Gana Koota is one of the most practically significant factors. Temperamental compatibility determines the texture of daily life together — whether the relationship feels naturally peaceful or perpetually edgy. A Deva-Rakshasa pairing (0 points) does not mean the relationship cannot work, but it does mean one person's natural gentleness will repeatedly encounter the other's intensity, and vice versa — requiring significant conscious adjustment from both.
Score interpretation: 0 or 5–6 points (rarely in between). A 0 here is worth taking seriously — not as a veto but as a significant temperamental difference to understand and work with consciously.
7. Bhakoot Koota — 7 Points
What it measures: Overall life direction, prosperity alignment, and the long-range trajectory of the relationship's effect on both people's lives.
This factor examines the Moon sign distance between the two people — specifically, what bhava (house) relationship the signs have. Certain sign relationships are considered bhakoot dosha — unfavourable configurations traditionally associated with one person's prosperity coming at the cost of the other's, or the two life trajectories being fundamentally misaligned:
- 6-8 relationship (one Moon sign is the 6th from the other's): Associated with health issues and obstacles
- 2-12 relationship (one sign is the 2nd from the other's): Associated with one-sidedness — one person giving significantly more than the other
Auspicious Bhakoot relationships: 1-1 (same sign), 1-7 (opposite signs), 3-11, 4-10, 5-9.
How points are awarded: Auspicious Bhakoot relationship = 7 points. 6-8 or 2-12 relationship = 0 points (Bhakoot Dosha).
In practice: Bhakoot is the second-highest weighted factor and one of the most practically significant. High Bhakoot (7 points) suggests the two people's life trajectories naturally support each other — the relationship creates mutual prosperity and forward movement. Bhakoot Dosha (0 points) suggests the relationship may involve one person advancing at the cost of the other, or both people working hard but finding the relationship itself draining rather than supportive.
Score interpretation: 0 or 7 points. Bhakoot Dosha (0) is a significant flag, especially in combination with Nadi Dosha (0 from factor 8).
8. Nadi Koota — 8 Points
What it measures: Constitutional health compatibility, genetic compatibility, and progeny potential.
Nadi refers to the three fundamental energy channels in Ayurvedic and yogic anatomy: Adi Nadi (Vata energy, associated with Air), Madhya Nadi (Pitta energy, associated with Fire), and Antya Nadi (Kapha energy, associated with Water and Earth). Each nakshatra is assigned to one of the three nadis:
Adi Nadi (Vata): Ashwini, Ardra, Punarvasu, Uttara Phalguni, Hasta, Jyeshtha, Mula, Shatabhisha, Purva Bhadrapada.
Madhya Nadi (Pitta): Bharani, Mrigashira, Pushya, Purva Phalguni, Chitra, Anuradha, Purva Ashadha, Dhanishtha, Uttara Bhadrapada.
Antya Nadi (Kapha): Krittika, Rohini, Ashlesha, Magha, Swati, Vishakha, Uttara Ashadha, Shravana, Revati.
How points are awarded: Different nadis = 8 points (full compatibility). Same nadi = 0 points (Nadi Dosha).
In practice: Nadi Dosha (same nadi, 0 points) is considered the most serious dosh in Ashtakoot matching. Traditionally, it is associated with health issues and difficulty with children. The underlying principle is that same-nadi partners share constitutional vulnerabilities — they reinforce each other's weak qualities rather than balancing them, potentially amplifying health susceptibilities.
Cancellation conditions: Nadi Dosha is considered cancelled in several circumstances: same Moon sign, same nakshatra, or when the 7th house lords are mutual friends. Fliyp applies standard cancellation rules automatically.
Score interpretation: 0 or 8 points. Nadi Dosha (0) without cancellation is the most significant single flag in Ashtakoot — worth noting, though not automatically a dealbreaker when other layers are strong.
Interpreting Your Total Ashtakoot Score
| Score | Traditional Assessment | Practical Reading | |-------|----------------------|-------------------| | 32–36 | Exceptional (Uttama) | Natural alignment across all or most factors. Very rare. | | 28–31 | Excellent (Madhyama Uttama) | Strong multi-dimensional compatibility. Most factors support the relationship. | | 24–27 | Good (Madhyama) | Solid compatibility with some areas requiring attention. | | 18–23 | Acceptable (minimum threshold) | Adequate compatibility — relationship can work with awareness and effort. | | Below 18 | Below traditional threshold | Significant incompatibilities in key factors. Requires careful consideration. |
The most important flag combination: Nadi Dosha + Bhakoot Dosha simultaneously (0 points in both the 7- and 8-point factors) = only 21 points possible from the remaining six factors. This combination is the most serious in traditional Vedic astrology and warrants genuine reflection, though it does not automatically rule out the relationship.
Frequently Asked Questions
Q: Which koota matters most? Nadi (8 points) carries the highest weight and is traditionally considered the most serious dosha. Bhakoot (7 points) is the second most significant. Gana (6 points) has high practical importance for daily relationship texture. These three — totalling 21 of 36 points — determine the majority of the Ashtakoot outcome.
Q: Is an Ashtakoot score of 18 genuinely sufficient? Traditionally yes — 18 is the minimum threshold. In practice, the composition of the 18 matters as much as the number. 18 points with Nadi and Bhakoot both scored (15 points) plus a few small factors is more meaningful than 18 points with Nadi Dosha and Bhakoot Dosha (requiring 18 from only 21 remaining points — very high performance elsewhere to compensate).
Q: Can two people with Nadi Dosha have a healthy relationship? Yes — many couples with Nadi Dosha have healthy, enduring relationships. Traditional concerns about health and progeny are not deterministic — they indicate an area requiring more attention, not a guaranteed outcome. The cancellation conditions, the strength of other kootas, and the additional compatibility layers (ascendant, Venus, 7th house) all contribute to the full picture.
Q: Do same-sex couples use the same Ashtakoot calculation? The Ashtakoot system was developed with male-female marriage in mind and some factors (Yoni, Bhakoot direction, Varna direction) have built-in gender assumptions. For same-sex couples, Fliyp calculates both directional versions and takes the more auspicious reading, focusing primarily on the factors (Nadi, Gana, Graha Maitri, Tara) that are not gender-dependent.
