When families ask about kundli milan, the number 36 comes up almost immediately. It is the maximum score in the ashtakuta system, the eight-category framework that most North Indian astrologers use to assess compatibility between a bride and groom. The system is old, practical, and widely misunderstood. Many people know the total but not what it measures or why certain kutas matter more than others.

What the ashtakuta system measures
The word ashtakuta means eight kutas, or categories. Each kuta examines a different dimension of compatibility: temperament, health, children, prosperity, emotional harmony. The Moon's nakshatra in each chart is the starting point for most calculations. Scholars derive the rules from classical texts including Muhurta Chintamani and the marriage chapters of Brihat Parashara Hora Shastra, though regional traditions differ in small ways.
The eight kutas are varna, vashya, tara, yoni, graha maitri, gana, bhakut and nadi. Each carries a maximum number of points. When the charts meet the condition for that kuta, the points are awarded. The total runs from zero to 36.
The eight kutas and their point values
| Kuta | Maximum points | What it measures |
|---|---|---|
| Varna | 1 | Spiritual compatibility, ego balance |
| Vashya | 2 | Mutual attraction, control dynamics |
| Tara | 3 | Health, well-being, longevity |
| Yoni | 4 | Sexual compatibility, physical nature |
| Graha maitri | 5 | Emotional friendship, mental rapport |
| Gana | 6 | Temperament: deva, manushya or rakshasa |
| Bhakut | 7 | Prosperity, family growth, children |
| Nadi | 8 | Health of offspring, genetic harmony |
Nadi carries the most weight because it relates to progeny and the continuation of the family line. Bhakut and gana follow. Varna, with only one point, is often the least decisive.
How points are awarded
Each kuta has its own rule. Varna awards one point if the groom's varna is equal to or higher than the bride's, reflecting traditional ideas about household leadership. Vashya checks whether the two nakshatras fall into compatible groups: human, quadruped, water-dwelling, wild or insect. Tara counts the lunar mansions from one Moon to the other and checks whether the resulting number falls into an auspicious group.
Yoni assigns each nakshatra an animal symbol and checks for natural friendship or enmity. Graha maitri compares the lords of the two Moon signs. Gana classifies each nakshatra as divine, human or demonic in temperament; deva-deva pairs score six points, deva-rakshasa pairs score zero. Bhakut examines the distance between the Moon signs. Nadi divides the 27 nakshatras into three groups, vata, pitta and kapha; if both belong to the same nadi, zero points are given and a condition called nadi dosha is said to exist.
What the total score means

Tradition holds that 18 points or more indicates acceptable compatibility. Many families today look for 24 or higher, especially in urban communities where choice is wider. A score below 18 is not a prohibition, but it prompts closer examination of the individual kutas and the charts as a whole.
The number alone does not tell the full story. A couple might score 20 points overall but have zero in nadi, which some families consider a serious concern. Another pair might score 28 but have weak graha maitri, suggesting emotional distance despite surface compatibility. Astrologers weigh the kutas differently depending on what the family values most.
Nadi dosha and other exceptions
Nadi dosha occurs when both charts fall into the same nadi. Classical texts treat it as a significant obstacle, linked to health and fertility. Some traditions cancel the dosha if the bride and groom have the same nakshatra or the same Moon sign, reasoning that the charts are already deeply aligned. Others allow exceptions if the couple belongs to different gotras or if other factors in the charts are exceptionally strong.
Bhakut dosha arises when the Moon signs are six-eight or two-twelve positions apart. Gana dosha appears in certain deva-rakshasa pairings. These conditions reduce the score but do not always prevent the match. Families consult astrologers to see whether other chart factors balance the deficiency.
Regional and scholarly differences
South Indian traditions often use a ten-kuta system called dashakuta, which includes papa-samya and other factors not part of the North Indian ashtakuta. Some Gujarati and Marwari families use a twelve-kuta framework. The points and thresholds differ, but the underlying idea remains the same: measure compatibility across multiple dimensions rather than relying on one factor.
Scholars also differ on whether to use the sidereal or tropical zodiac, though most Vedic astrologers use sidereal. The choice of ayanamsa, the correction applied to account for precession, can shift a nakshatra boundary by a few minutes of arc and change the kuta score in borderline cases.
Using the system today
Families in Toronto and New Jersey often request a kundli milan report before proceeding with a match. The free matchmaking page on this site calculates the ashtakuta score and explains which kutas are strong and which need attention. The compatibility page offers a broader view, including planetary dashas and the seventh house, which the guna score does not address.
The 36-guna system is a starting point, not a final answer. It works best when both families understand what the numbers represent and are willing to look at the whole chart, the individuals involved, and the practical realities of building a life together.
A framework, not a formula
The ashtakuta system has survived because it is systematic and transparent. Each kuta has a rule, each rule has a reason, and the points add up in a way that families can discuss. It does not replace conversation, character or common sense, but it offers a shared language for a decision that matters deeply.
