Why families match kundalis before a marriage
Where marriages are arranged, the two families are often making a decision before the couple has spent much time together. Kundali matching gives them a structured framework for that conversation — eight named factors, each with a weight, covering the areas a marriage is most likely to be tested on.
That is worth stating plainly, because it explains both the usefulness and the limits of the exercise. Guna Milan is a checklist drawn from classical texts. It is not a prediction, and the tradition itself does not treat it as one — which is why every dosha in the system comes with documented conditions that cancel it.
What each koota means for married life
- Nadi (8 points) — health and children. The heaviest single koota, and the one most likely to sink an otherwise good score.
- Bhakoot (7 points) — money, family harmony and the general prosperity of the household.
- Gana (6 points) — temperament. Whether two natures complement each other or grate under pressure.
- Graha Maitri (5 points) — friendship and shared outlook. Often the koota astrologers weigh most heavily in practice.
- Yoni (4 points) — physical and sexual compatibility.
- Tara (3 points) — fortune, longevity and freedom from disruption.
- Vashya (2 points) — mutual influence, and whether the balance of it feels supportive.
- Varna (1 point) — work ethic and inner temperament. Frequently misread as a caste check; it is calculated from the moon sign and is worth a single point.
North Indian and South Indian systems
The 36-point Ashtakoota used here is the northern system. Across much of South India the equivalent practice is Dashakoota, or the ten Poruthams — Dina, Gana, Mahendra, Stree Deergha, Yoni, Rashi, Rajju, Vedha, Vashya and Nadi. They overlap in places and diverge in others, and they weigh things differently.
A pair can score well under one and poorly under the other. That is not a contradiction to be resolved; they are separate traditions with separate rules, and families generally follow the one their community follows.
If the score comes back low
A total below 18 is where astrologers advise a closer look, not where they advise calling it off. What matters next is which points were lost. Losing Nadi and Bhakoot together costs 15 of the 36 on its own, and both have classical cancellation conditions that a full chart reading may find apply.
Beyond that, the traditions prescribe remedies rather than refusals — pujas, gemstones, charitable acts, timing the wedding to a favourable muhurta. And most astrologers will tell you that the seventh house, the condition of Venus, and the dasha periods both partners are running matter more to a marriage than the raw guna total ever did.
If you do not have exact birth times, the date-of-birth match gives the same guna score. With no birth details at all, there is matching by name.
