The short answer
18 out of 36 is the traditional minimum for a match to proceed. But the number alone is only half the story — experienced astrologers care just as much about which kootas matched. A score of 21 with full marks in Nadi and Bhakoot is often viewed more favourably than 27 with a Nadi dosha.
Here is how the score bands are traditionally read:
Why 18 is the minimum
The 18-point threshold is simply half of 36 — the traditional line at which the matching forces are seen to outweigh the mismatching ones. It is a rule of thumb passed down through classical practice, not a scientifically derived cutoff.
Worth knowing: the threshold is about the first check, not the final decision. Many astrologers will green-light a 19 with a clean Nadi and Bhakoot while advising caution on a 23 with a Nadi dosha. The total opens the door; the koota-by-koota breakdown decides how comfortable everyone feels walking through it.
Which kootas matter most
Not all points are equal. The three heavyweight kootas — Nadi (8), Bhakoot (7) and Gana (6) — together make up 21 of the 36 points. Their status shapes the reading of the whole score:
- Full Nadi (8/8): the single most reassuring result in the system. It removes the most feared dosha entirely.
- Full Bhakoot (7/7): traditionally read as strong emotional harmony between the two Moon signs.
- Full Gana (6/6): similar temperaments — Deva with Deva, Manushya with Manushya.
Conversely, zeros in these heavy kootas — Nadi Dosha or Bhakoot Dosha — are what pull scores down hard and worry families most. Light kootas like Varna (1) and Vashya (2) fine-tune the score but rarely decide anything on their own.
What if the score is low?
A low score can be alarming — especially when families see a number like 14. But tradition offers several paths before anyone concludes anything:
- Check for cancellations. Nadi Dosha is cancelled when both partners share the same nakshatra in different padas; Bhakoot Dosha is cancelled when both Moon signs share the same lord. These classical exceptions can restore points.
- Look beyond the eight kootas. Guna Milan is a first check. A full reading also considers Mangal dosha, planetary periods (dashas), the strength of both complete horoscopes, and yogas that the koota system ignores entirely.
- Consider remedies. For doshas that stand, astrologers traditionally prescribe remedies — pujas, mantras, donations — that give families confidence to proceed.
- Weigh the human factors. Values, temperament, life goals and mutual respect decide marriages far more than star scores. Many happy couples exist at every point on the 36-point scale.
A low score is information, not a verdict. Treat it as the start of a deeper conversation — with each other, with your families, and with a qualified astrologer — rather than the end of one.
A respectful note
Guna Milan comes from centuries of Vedic tradition, and millions of families consult it with genuine faith. It is meant here as a traditional guide and a starting point for conversation — entertaining and meaningful to many, but not a verdict on two people. For important decisions, families traditionally consult a qualified astrologer who studies both complete horoscopes, not just the eight kootas.
