Ashtakoot (literally “eight categories”) is the foundation of Vedic kundli matching the system that produces the famous “X out of 36 guna” score most matchmaking sites show. But almost every online tool stops at the number. They never tell you which of the eight kootas you actually failed, which failure is fixable, and which one is non-negotiable.
This guide breaks down all 8 kootas Varna, Vashya, Tara, Yoni, Graha Maitri, Gana, Bhakut, and Nadi with their exact point weightage, what they really test, and what a low score in each one means for a real marriage.
Quick Verdict: What Ashtakoot Score Actually Means
A total of 18 out of 36 is the minimum acceptable Ashtakoot score for marriage in classical Vedic astrology. But the composition of those points matters more than the total. A 26/36 score with a failed Nadi koot is a worse match than a 19/36 score where all 8 kootas score at least partial points.
Two kootas: Bhakut and Nadi are weighted so heavily that failing them can technically cancel a 30+ guna match unless specific dosha-cancellation rules apply.
The 8 Kootas at a Glance: Points and Purpose
- Varna (1 point): Spiritual/work compatibility ego and life-orientation.
- Vashya (2 points): Mutual attraction and dominance who has the upper hand.
- Tara / Dina (3 points): Health, well-being and longevity of the union.
- Yoni (4 points): Sexual chemistry and physical/biological compatibility.
- Graha Maitri (5 points): Mental and intellectual compatibility friendship of moon-sign lords.
- Gana (6 points): Temperament Deva, Manushya or Rakshasa nature.
- Bhakut (7 points): Financial prosperity, progeny, family harmony.
- Nadi (8 points): Genetic/Ayurvedic compatibility health of children.
Total: 36 guna. Acceptable: 18+. Excellent: 28+. Below 18 = match generally rejected unless strong cancellations apply.
1. Varna Koot (1 point): Spiritual & Work Compatibility
Varna refers to the four classical varnas based on Moon sign: Brahmin (highest), Kshatriya, Vaishya, and Shudra. It indicates your inner orientation spiritual, warrior, mercantile, or service-oriented.
How Varna is calculated
- Brahmin: Cancer, Scorpio, Pisces (water signs)
- Kshatriya: Aries, Leo, Sagittarius (fire signs)
- Vaishya: Taurus, Virgo, Capricorn (earth signs)
- Shudra: Gemini, Libra, Aquarius (air signs)
Pass/fail rule
You get 1 point if the groom's varna is equal to or higher than the bride's. If the bride's varna is higher, you score 0. Modern interpretation treats this as compatibility of life-orientation rather than caste hierarchy.
What a Varna mismatch really means
A 0 in Varna alone is the least serious failure it only costs you 1 point. It tells you that one partner may pursue more spiritual/idealistic goals while the other is more practical or material. Easily managed with awareness.
2. Vashya Koot (2 points): Attraction & Influence
Vashya measures who naturally has emotional pull over whom. Each Moon sign belongs to one of five vashya groups: Chatushpada (four-footed), Manava (human), Jalachara (aquatic), Vanachara (wild), and Keeta (insect).
Scoring
- Same vashya group: 2 points (full)
- Friendly groups (e.g. Manava with most others): 1 point
- Hostile groups (e.g. Keeta with Manava): 0 points
Real-world reading
A low Vashya score predicts a relationship where one partner constantly tries to control or convince the other. Not fatal most modern couples adapt but worth knowing before marriage.
3. Tara / Dina Koot (3 points): Health & Destiny
Tara koot examines the relative nakshatra positions. Count the nakshatras from the bride's birth star to the groom's, divide by 9. The remainder determines which of the 9 taras applies.
Auspicious vs. inauspicious taras
- Auspicious (full points): Sampat (2nd), Kshema (4th), Sadhaka (6th), Mitra (7th), Param-Mitra (9th)
- Inauspicious (zero points): Janma (1st), Vipat (3rd), Pratyari (5th), Vadha (8th)
Both directions (bride-to-groom and groom-to-bride) are checked. Each direction is worth 1.5 points, totaling 3.
What a Tara failure signals
Health concerns, accidents, frequent illness in the marriage, or sudden disruptive events. Strong remedial scope through nakshatra-based remedies.
4. Yoni Koot (4 points): Sexual & Biological Compatibility
Yoni assigns each nakshatra to one of 14 symbolic animal yonis (Horse, Elephant, Sheep, Snake, Dog, Cat, Rat, Cow, Buffalo, Tiger, Deer, Monkey, Mongoose, Lion). It measures instinctive sexual and emotional chemistry.
Scoring rule
- Same yoni: 4 points (max)
- Friendly yonis: 3 points
- Neutral yonis: 2 points
- Unfriendly yonis: 1 point
- Enemy yonis (e.g. Cat–Rat, Snake–Mongoose, Cow–Tiger, Lion–Elephant, Dog–Deer, Monkey–Sheep, Horse–Buffalo): 0 points
Why this is the most ignored koot
Most apps quietly show “2 out of 4” in Yoni and you tick it. But a 0 in Yoni enemy yoni historically predicts long-term physical and intimacy issues. Worth a deeper look before commitment.
5. Graha Maitri Koot (5 points): Mental Compatibility
This is the most weight-bearing koot for emotional/intellectual fit. It checks the friendship between the lords of the bride's and groom's Moon signs (Rashi lords).
Scoring scale
- Both lords are mutual friends: 5 points
- One friend, one neutral: 4 points
- Both neutral: 3 points
- One friend, one enemy: 1 point
- Both enemies: 0 points
What this really tests
Graha Maitri predicts whether you will mentally understand each other without explanation. Couples with high Graha Maitri rarely have communication issues; couples with 0 Graha Maitri often describe each other as “living in different worlds.”
6. Gana Koot (6 points): Temperament Compatibility
Each of the 27 nakshatras is classified into one of three Ganas: Deva (divine), Manushya (human), Rakshasa (demonic). This isn't a moral label it describes core temperament.
Gana matching matrix
- Same gana: 6 points
- Deva – Manushya: 5 points
- Manushya – Rakshasa: 1 point (often 0)
- Deva – Rakshasa: 0 points (most problematic)
Cancellation of Gana dosha
Gana dosha is cancelled if (a) Moon sign lords are friends, (b) Rashi lords are the same, or (c) the navamsha lords are friends. Most matchmakers skip this check entirely ask for it explicitly.
7. Bhakut Koot (7 points): Prosperity, Children, Family Life
Bhakut is calculated from the relative position of the two Moon signs in the zodiac (e.g. 1st-7th, 2nd-12th, 6th-8th, etc.). Certain positions are considered destructive.
Bhakut doshas (0 points)
- Dwi-Dwadasha (2/12): financial drain, separation
- Shadashtak (6/8): health issues, conflict, longevity concerns
- Nav-Pancham (5/9): issues with progeny and harmony
Bhakut dosha cancellation
See our detailed guide on Bhakut and Manglik cancellations for the exact conditions a low Bhakut alone is not a deal-breaker if these apply.
8. Nadi Koot (8 points): Genetic & Progeny Health
Nadi is the heaviest single koot in the entire system. Each nakshatra belongs to one of three Nadis: Aadi (Vata), Madhya (Pitta), and Antya (Kapha) the three Ayurvedic doshas.
Scoring
- Different Nadis: 8 points (full)
- Same Nadi: 0 points Nadi Dosha
Why Nadi dosha is treated as severe
Classical texts treat same-Nadi unions as genetically incompatible, with risks to progeny health and miscarriage. This is the one koot where a 0 score historically meant the match was rejected outright.
When Nadi dosha is cancelled
Nadi dosha has 7 well-documented cancellation conditions same Rashi, same nakshatra but different pada, retrograde planets in specific positions, etc. Read our complete Nadi dosh cancellation guide before rejecting a match based on Nadi alone.
Sample Ashtakoot Score Calculation
Suppose Bride is born under Rohini nakshatra (Taurus Moon) and Groom under Mrigashira nakshatra (Taurus/Gemini boundary). A typical breakdown:
- Varna: 0/1 (Vaishya–Shudra)
- Vashya: 2/2
- Tara: 3/3 (Sampat both directions)
- Yoni: 3/4 (Snake–Snake, considered friendly but with caution)
- Graha Maitri: 5/5 (Venus–Mercury, neutral-to-friend)
- Gana: 6/6 (both Manushya)
- Bhakut: 7/7 (no dosha)
- Nadi: 8/8 (Antya vs. Aadi)
Total: 34/36 an excellent classical match.
What Most Kundli Matching Tools Miss
Most websites report only the total guna score. The serious gaps:
- They ignore dosha cancellations. A failed Bhakut or Nadi is often technically cancelled by other yogas in the chart, but apps do not check this.
- They ignore Manglik dosha entirely. Ashtakoot does not include Mangal dosha a 36/36 Ashtakoot score with severe Manglik dosha can still be a hard match.
- They don't weight kootas correctly. A 25/36 with failed Nadi is worse than 22/36 with all 8 kootas passed.
- They use name-based nakshatras, which is astrologically unreliable. Always use the birth-time Moon nakshatra.
How to Read Your Own Ashtakoot Score in 60 Seconds
- Step 1. Note the score in each individual koota don't just look at the total.
- Step 2. Check Nadi first. If 0/8, look up cancellation conditions before doing anything else.
- Step 3. Check Bhakut. If 0/7, check Moon-lord friendship and Navamsa Moon positions.
- Step 4. Check Gana. If Deva–Rakshasa pairing, look for cancellation by Rashi-lord friendship.
- Step 5. Only if all three above are clear (or cancelled), interpret the total score as your final guna count.
Bottom Line
Ashtakoot is a starting filter not a final verdict. The number you see (18/36, 26/36, 32/36) means very little without knowing which kootas failed and whether dosha cancellations apply. A serious analysis must always include Manglik check, Navamsa cross-check, and dasha timing alongside the Ashtakoot score.
If you want a full Ashtakoot breakdown plus dosha cancellation analysis from your actual birth chart not just nakshatra name matching try MatchCheck's free Kundli analysis. It checks all 8 kootas individually and explicitly flags every cancellation rule that applies to your chart.
