Most families in India still ask for the kundli before they ask for anything else. The photo, the job, the family background all come later. First comes the question: “How many gunas matched?”
That number gets a lot of weight. Sometimes too much. A score of 28 makes everyone relax, a score of 16 can end a proposal on the spot, and very few people stop to ask what those points are actually measuring. This guide walks through how kundli matching for marriage works, what the 36 gunas mean, and why a good astrologer never stops at the score.
What is kundli matching?
Kundli matching, also called Gun Milan or horoscope matching, compares the birth charts of two people before marriage. The most common method in North and East India is Ashtakoota Milan, which looks at eight factors (koots) based mainly on the position of the Moon in each chart. In the South, many families use a similar system called Dashakoota or Porutham, which checks ten factors.
Both systems try to answer a practical question. Will these two people understand each other, stay healthy together, and build a stable family? The method is old, but the worry behind it is very modern.
The 36 gunas explained, one koot at a time
Each of the eight koots carries a fixed number of points. Add them up and you get 36.
- Varna (1 point) looks at temperament and how each person approaches work and duty.
- Vashya (2 points) checks mutual attraction and who tends to influence whom.
- Tara (3 points) relates to birth stars and is linked with health and general fortune.
- Yoni (4 points) deals with physical compatibility and intimacy.
- Graha Maitri (5 points) compares the lords of the two Moon signs. This one says a lot about friendship and day to day understanding.
- Gana (6 points) groups people into Deva, Manushya and Rakshasa temperaments.
- Bhakoot (7 points) looks at the distance between the two Moon signs and is tied to family growth and finances.
- Nadi (8 points) carries the most weight and is traditionally linked to health and children.
You will notice the points climb as you go down the list. The later koots were considered more serious, which is why a problem in Bhakoot or Nadi worries families far more than a low Varna score.
How many gunas should match for marriage?
The usual rule is simple:
- Below 18: generally not recommended without a deeper look.
- 18 to 24: acceptable, and very common.
- 25 to 32: good compatibility.
- Above 32: excellent on paper.
Here is the part people skip. A couple with 30 gunas can still have a difficult chart, and a couple with 19 can do very well. The score only measures Moon-based compatibility. It says nothing about the seventh house, the condition of Venus or Jupiter, or the dasha each person will be running after marriage.
Nadi dosha and Bhakoot dosha
These two cause the most anxiety, so they deserve a clear explanation.
Nadi dosha happens when both partners fall in the same Nadi (Aadi, Madhya or Antya). The match then gets zero out of eight points. Traditionally it was linked with health issues and difficulty with children. But classical texts also list several cancellations, for example when both people share the same Moon sign but different nakshatras, or when the lords of their Moon signs are friendly.
Bhakoot dosha appears when the two Moon signs sit in certain positions from each other, like 6-8, 2-12 or 5-9. It is often cancelled when the sign lords are the same planet or are natural friends.
So a dosha showing up in software is a starting point. Whether it actually applies needs a person to check the cancellations by hand.
What gun milan does not tell you
I’ll be direct: if your astrologer only gives you a number, ask for more. A proper marriage compatibility reading should also cover:
- The seventh house and its lord in both charts, since this is the house of partnership.
- Venus for both partners, and Jupiter as well, especially in a woman’s chart in traditional reading.
- Manglik status. If one partner is Manglik and the other is not, it needs to be looked at carefully. (We have a full guide on Manglik dosha and its remedies.)
- The current and upcoming dashas, because a couple entering a tough period together is different from one entering a smooth one.
- The Navamsa chart (D9), which many astrologers treat as the real chart of marriage.
Online calculators are fine for a first check. They are quick and free. They just can’t weigh one factor against another, and that weighing is where the actual reading happens.
What if the kundli does not match?
This question comes up more often than you’d think, usually when two people already care about each other and the families are worried.
A low score is not a verdict. First, get the cancellations checked. A large share of “no match” results change once someone looks at the full chart. Second, if a real dosha remains, there are traditional remedies, from specific pujas to mantra practice. Third, and this matters as much as anything in the chart, talk to each other. Values, money habits, how you handle family pressure. Astrology can point out where friction may show up. It can’t replace an honest conversation.
What you need for kundli matching
For an accurate match, keep these details ready for both people:
- Date of birth
- Exact time of birth (from a birth certificate or hospital record if possible)
- Place of birth
Birth time matters more than most people realise. Even a 15 to 20 minute error can shift the ascendant, and sometimes the nakshatra, which changes the whole match.
Frequently asked questions
Is 18 gunas enough for marriage?
Eighteen is the traditional minimum. Many happy marriages sit in the 18 to 24 range. What matters more is whether Nadi or Bhakoot dosha is present and whether it is cancelled.
Can kundli matching be done without birth time?
A rough match can be done using the Moon sign or name-based nakshatra, but it is far less reliable. If the time is unknown, an astrologer can sometimes estimate it through birth time rectification.
Is online kundli matching accurate?
The guna calculation itself is usually correct. The problem is that software rarely checks dosha cancellations or the seventh house properly, so the conclusion can be misleading.
Does Nadi dosha always mean the marriage will fail?
No. Nadi dosha has well known cancellations, and even when it applies, it is one factor among many.
Get your kundli matched properly
If you’re about to make a decision based on a guna score, it’s worth getting a full reading first. Astrologer Koushik Chatterjee at Cosmic Destiny looks at both charts in full, including the seventh house, Navamsa, dashas and dosha cancellations, and explains the result in plain language. Book a consultation and come with your questions. Families usually have a few.
