Kundli matching
Nadi Dosha
Nadi is the heaviest of the eight kootas, worth 8 of the 36 points. When the bride and groom share a nadi it scores zero, and that is Nadi dosha.
The three nadis
Every nakshatra belongs to one of three nadis, which tradition links to the three Ayurvedic constitutions. Partners of the same nadi are said to share a constitution, and the texts read this for health and, above all, for the health of children.

How common it is
Because each nadi holds exactly nine nakshatras of equal span, any two people share a nadi exactly one time in three. Once the cancellations below are applied, it stays in effect for about 29% of all possible pairs. Of all matches scoring under 18, 71% have Nadi dosha.
When Nadi dosha is cancelled
- Both Moons in the same sign, but in different nakshatras. (Later classical)
- The same nakshatra, but the Moons in different signs, which happens with the six nakshatras that span two signs. (Later classical)
- The same nakshatra and sign, but different padas. (Regional: not accepted everywhere)
Some astrologers apply further exceptions, for example when the sign lords are the same or friendly, or when the rest of the match is strong. The calculator shows only the three above, because they are the ones most widely agreed.
