If you are looking at marriage, parents looking at marriage for you, or a partner who has been asked to share birth details, you have already met kundali matching. What you may not know is what the score actually measures, what it does not measure, and why a "good" score is not the same thing as a good marriage.
Quick Answer
Kundali matching (also called guna milan or Ashtakoot) compares two birth charts using eight criteria. Each criterion (guna) carries a fixed maximum of points; the total maximum is 36. A score of 18 or higher is traditionally considered acceptable for marriage. The system also checks for Mangal dosha and other compatibility flags. Online tools calculate the score automatically, but the score is the start of the analysis, not the end.
The 8 Gunas (Ashtakoot)
Each guna scores a different layer of compatibility. Both partners' Moon signs and nakshatras are the basis for almost every calculation.
- Varna (1 point), spiritual and temperamental class. Tests broad psychological compatibility.
- Vashya (2 points), mutual influence between partners.
- Tara (3 points), well being and longevity in the relationship, based on nakshatra distance.
- Yoni (4 points), physical and sexual compatibility, drawn from the animal symbolism of nakshatras.
- Graha Maitri (5 points), mental and emotional compatibility from Moon sign lords.
- Gana (6 points), temperamental nature: deva, manushya, rakshasa.
- Bhakoot (7 points), emotional and economic prosperity, based on Moon sign distance.
- Nadi (8 points), genetic and health compatibility, based on nakshatra grouping.
Maximum total: 36.
What the Score Actually Means
- Below 18, traditionally not recommended.
- 18 to 24, acceptable; workable with effort.
- 25 to 32, very good match.
- 33 to 36, exceptional, rare.
The catch: a high Ashtakoot score is necessary but not sufficient. The score measures the surface layer of compatibility (temperament, communication, physical alignment, emotional rhythm). It does not measure the deeper layers: career chart compatibility, joint dasha timing, the seventh house and its lord, Venus and Jupiter for the woman, Mars for the man, the navamsha (D9) chart, and the joint progression of both lives.
What Mangal Dosha Means in Matching
Mangal dosha (or Manglik dosha) refers to Mars placed in the 1st, 2nd, 4th, 7th, 8th, or 12th house from the lagna in one partner's chart. Traditional matching considers a Mars affected chart problematic if matched with a non Manglik chart, particularly affecting the 7th house and marriage longevity.
In practice, Manglik analysis has nuance. Mars placed in a friendly sign, aspected by Jupiter, or paired with another Manglik chart often cancels the dosha. Modern astrology also weighs Mars's overall strength and the navamsha placement. See the full Mangal dosha explanation for detail.
Is Online Kundali Matching Accurate?
The calculation is accurate. Any reputable Vedic software will produce the same Ashtakoot score given the same birth data. What online tools cannot do is interpret. Two pairs with identical 28 of 36 scores can have radically different chart level realities.
The score is the starting point of the conversation, not the conclusion. Skilled kundali matching reads:
- Both 7th houses and their lords
- Venus (for both) and Jupiter (for the woman)
- Mars (for both, but especially the man)
- Joint dasha sequence over the next 10 to 20 years
- Navamsha (D9) compatibility, often more telling than the rashi chart
- Specific yogas affecting marriage
"A 32 of 36 score with a 7th house Saturn afflicting both charts will hurt more than a 22 of 36 score with strong Venus and Jupiter in both."
What Online Kundali Matching Is Good For
The free online tools are genuinely useful as a first filter. If the score is high and Mangal compatibility is clean, the broad compatibility is good and you can proceed to deeper reading. If the score is below 18, especially with Nadi or Bhakoot dosha, the underlying friction is real and warrants careful evaluation.
What online tools cannot replace is a personal reading from an astrologer who looks at both navamshas, both dasha sequences, the timing of marriage in each chart, and how the joint future looks across the next two decades.

Book a Kundali MatchingFrequently Asked Questions
Do I need exact birth time for kundali matching?
Yes. The Moon position, nakshatra, and lagna all depend on birth time. A 30 minute uncertainty can shift the score meaningfully.
Can a low matching score be remedied?
Vedic tradition lists several remedies. The bigger question is whether the underlying compatibility justifies the remedy. A thoughtful matching reading distinguishes ritual remedies from situations where the score is signalling a deeper issue.
What if one of us does not believe in kundali matching?
That is fine. The matching is a tool, not a verdict. It can still surface things worth being aware of, which makes for better conversations even if neither partner uses it for decision making.
How does Medha do kundali matching?
Both charts are read in full, not just the Ashtakoot score. Medha looks at the 7th house and its lord, navamsha (D9), joint dasha sequence, Mangal nuance, and the broader life direction of each partner. Most matchings are delivered via WhatsApp within 5 days.
Is kundali matching only for arranged marriages?
No. Many love marriage couples request matching to understand their joint chart before committing. The reading is the same; the framing differs.
