Kundali matching — also called Guna Milan or Ashtakoota Milan — is the Vedic astrological system for assessing matrimony compatibility. Before a marriage is finalised in most Indian families, both horoscopes (kundali/jatakam/janam patri) are matched. This guide explains exactly how the system works, what each Koota assesses, and how to interpret a kundali score.
What Is Kundali Matching?
Kundali matching compares two birth charts — calculated from the exact birth date, time, and place of each person — to determine compatibility across eight categories. Each category awards a certain number of points, totalling 36. The higher the score, the more compatible the couple is considered.
The 8 Kootas: What Each Measures
1. Varna Koota (1 point)
Varna assesses the spiritual development and general temperament of each person. The four Varnas are Brahmin (spiritual), Kshatriya (warrior), Vaishya (merchant), and Shudra (service). The groom's Varna must be equal to or higher than the bride's for full compatibility. Score: 0 or 1 point.
2. Vashya Koota (2 points)
Vashya measures the natural dominance or attraction in the relationship — who leads and who follows in different aspects of life. Compatibility here indicates mutual attraction and influence. The 12 zodiac signs are grouped into Manav (human), Chatushpad (quadruped), Jalchar (aquatic), Vanchar (wild), and Keet (insect) categories for this calculation.
3. Tara Koota (3 points)
Tara compares the birth stars (Nakshatras) of the bride and groom to assess health, well-being, and longevity in the relationship. There are 27 Nakshatras. The groom's Nakshatra is counted from the bride's, and vice versa. Even numbers indicate compatibility; odd numbers may indicate challenges.
4. Yoni Koota (4 points)
Yoni represents sexual compatibility and intimacy between the couple. Each Nakshatra is associated with an animal symbol (horse, elephant, sheep, serpent, dog, cat, rat, cow, buffalo, tiger, hare, monkey, lion, or mongoose). Compatible animal pairs score 4 points; enemies score 0.
5. Graha Maitri Koota (5 points)
Also called Rashyadhipati Koota. This assesses intellectual compatibility and the emotional bond between the couple by comparing the lords of their Moon signs (Rashi). Friendly lords = 5 points; neutral = 3; enemies = 0. This is considered one of the most important Kootas for long-term compatibility.
6. Gana Koota (6 points)
Gana measures temperament and personality type. The 27 Nakshatras are divided into three Ganas: Deva (divine/gentle), Manushya (human/balanced), and Rakshasa (intense/passionate). Deva-Deva and Manushya-Manushya matches score full points. Deva-Rakshasa combinations traditionally score 0 and are considered challenging, though modern astrologers note that personality balance can compensate.
7. Bhakoot Koota (7 points)
Bhakoot (also called Rashi Koota) assesses the emotional compatibility and financial well-being of the couple based on their Moon signs. Certain Rashi combinations (1–7, 2–12, 3–11, 4–10, 5–9, 6–8) are considered incompatible and score 0 — these are called Bhakoot Dosha. This is the second-highest scoring Koota and is taken very seriously.
8. Nadi Koota (8 points) — The Most Important
Nadi is the highest-scoring Koota and is given the most weight in matching. Nadi assesses the genetic and physiological compatibility — specifically, whether the couple's Prakriti (constitution) is compatible. The three Nadis are: Aadi (Vata constitution), Madhya (Pitta constitution), and Antya (Kapha constitution). If both persons have the same Nadi, it is called Nadi Dosha and scores 0 — it is one of the three major doshas in kundali matching.
The three major doshas that can override an otherwise good score are: Nadi Dosha (same Nadi), Bhakoot Dosha (incompatible Moon sign positions), and Gana Dosha (Deva-Rakshasa or Manushya-Rakshasa combination). Experienced astrologers check for cancellation conditions before declaring any dosha active.
What About Manglik Dosha?
Manglik (or Mangal) dosha is assessed separately from the 36-Guna system. It occurs when Mars (Mangal) is placed in the 1st, 2nd, 4th, 7th, 8th, or 12th house of the birth chart. While important in matrimony matching (especially in South India, where it is called Chevvai dosham in Tamil or Kuja dosham in Telugu/Kannada), it does not reduce the 36-Guna score.
Importantly: if both the bride and groom have Mangal dosha, it is widely considered to neutralise — the dosha cancels itself. There are also several other cancellation conditions that a qualified astrologer can assess.
Interpreting Your Kundali Score
- 32–36: Excellent match — very rare
- 27–32: Very good match — highly recommended
- 24–27: Good match — recommended
- 18–24: Average match — acceptable with consideration
- Below 18: Potentially challenging — consult a qualified astrologer
How VivahSphurthi's Kundali Matching Works
VivahSphurthi's kundali matching tool uses the same Ashta Koota method. When you enter your birth date, time, and place (and the profile you are matching with has their data entered), the system calculates both birth charts and provides the full 36-Guna breakdown — including individual Koota scores, Mangal dosha status, and Nadi/Bhakoot/Gana dosha flags.
Premium members can access a full Kundali PDF report with a detailed compatibility narrative, auspicious months, and suggested remedies if doshas are present.
