21 out of 36 gunas falls in the acceptable band (18-24) in kundli matching (Gun Milan) — three points above the classical pass mark of 18. That band is traditionally read as madhyam: middling but workable. An 18 and a 21 sit in the same band and get the same reading; what separates one 21 from another is which kootas earned the points.
A 21 that clears the two heaviest kootas — Nadi (8 points) and Bhakoot (7 points) — reads very differently from a 21 that loses one of them and makes the total up elsewhere. The headline number never shows which kootas actually cleared.
Where the number comes from: the Ashtakoot system
Kundli matching in North-Indian Vedic astrology uses Ashtakoot Milan — the "eight-fold" (ashta = eight, koot = category) comparison of the bride's and groom's birth charts, based mainly on the Chandra rashi (Moon sign) and nakshatra (birth star) of each person. Each of the eight kootas is worth a fixed number of points, adding up to 36:
| Points | Koota | What it weighs |
|---|---|---|
| 1 | Varna (वर्ण) | Ego / work-nature compatibility |
| 2 | Vashya (वश्य) | Mutual influence, give-and-take |
| 3 | Tara (तारा) | Birth-star health & wellbeing |
| 4 | Yoni (योनि) | Instinctive / physical compatibility |
| 5 | Graha Maitri (ग्रह मैत्री) | Mental affinity, friendship of the two Moon-sign lords |
| 6 | Gana (गण) | Temperament type (dev / manushya / rakshasa) |
| 7 | Bhakoot (भकूट) | Emotional bond & family wellbeing |
| 8 | Nadi (नाड़ी) | Constitution (Aadi / Madhya / Antya) & progeny |
Add the eight and you get a score out of 36. That single figure — the गुण guna score — is what "21/36" or "18/36" refers to.
Is 21 a good score?
It's an acceptable one. 18 is the floor of the band and 21 clears it by three points, but both sit in the same 18-24 madhyam range. A 33-36 total is rare because it needs full marks on Nadi (8) and Bhakoot (7) at the same time, on top of near-perfect scores across the six smaller kootas. So the useful question at 21 is not "is it high enough" but "which of the eight kootas earned it".
| Score | Traditional reading |
|---|---|
| Below 18 | Not recommended on gunas alone |
| 18 – 24 | Acceptable (madhyam) — 21 sits here, as does 18 |
| 25 – 32 | Very good compatibility |
| 33 – 36 | Excellent (rare in practice) |
Different lineages draw these band lines slightly differently; Ravitra's own in-app summary uses the same three grades with marginally different cut-offs, and always shows the eight kootas alongside — never the total alone.
What the guna score does not tell you
This is the part most score-only reports skip, and it matters more at 21 than the number suggests. Two kootas carry most of the weight, and a total can hide both:
- Nadi dosha (नाड़ी दोष) — worth 8 points, the single biggest koota. If both partners share the same Nadi, those 8 points are lost. A 21/36 that includes the full 8 Nadi points is a fundamentally different match from a 21/36 that lost them and made the total up across the smaller kootas.
- Bhakoot dosha (भकूट दोष) — worth 7 points, tied to the Moon-sign positions between the two charts. Certain rashi combinations trigger it.
Both have recognised cancellation (parihara) conditions in the classical texts — a same-Nadi or Bhakoot flag can be nullified by other factors in the charts, which a raw number never shows. Separately, Mangal dosha (मंगल दोष / manglik) is not part of the 36-guna count at all — it's checked independently, so a 21/36 score tells you nothing about whether either person is manglik.
The honest takeaway: a 21/36 is a real, acceptable score — three points past the classical pass mark — but it's still a filter, not a verdict on a marriage. Two matches can share the same 21 and clear completely different kootas. If a chart doesn't clearly support something, the honest answer is to say so, not to hide it inside one blended number.
How Ravitra reads a match
Ravitra runs the full Ashtakoot Milan the classical way — all eight kootas scored and shown individually, so Nadi and Bhakoot are never hidden inside one blended number, plus a separate Mangal-dosha read whose own classical cancellation conditions are checked against both charts — then explains the result in plain words: what the score means for you, where the strengths are, and where the chart stays quiet. No fear, no fake muhurat dates, nothing to buy.

Is 21 out of 36 gunas a good score?
21/36 falls in the acceptable band (18-24), three points above the classical pass mark of 18 — traditionally read as madhyam: middling but workable. An 18 and a 21 sit in the same band; what separates them is which kootas scored. 25-32 is read as very good, 33-36 as excellent.
Is 21 gunas enough to proceed with marriage?
On the guna count alone, 21 clears the traditional bar. But the total is one input. The same 21 could include a same-Nadi dosha (0 of 8 points there, made up elsewhere) or clear Nadi cleanly — the two charts read very differently even at an identical total. A real reading checks the kootas individually, not just the sum.
Why do two 21/36 matches feel so different?
36 points split across eight kootas of very unequal weight (1 to 8 points each), so the same total of 21 can be built in different ways. One chart might clear the two heaviest kootas — Nadi (8) and Bhakoot (7) — and lose points on smaller ones. Another might lose the Nadi points entirely and make the total up elsewhere. The headline number hides which kootas actually cleared.
What is the maximum guna score?
36 is the maximum — the eight kootas total 36 points (Varna 1, Vashya 2, Tara 3, Yoni 4, Graha Maitri 5, Gana 6, Bhakoot 7, Nadi 8). A perfect 36 is very rare — it needs full marks on Nadi (8) and Bhakoot (7) together, on top of near-perfect scores across the six smaller kootas.
Does a high guna score guarantee a happy marriage?
No. A high score means the two charts align well on the eight Ashtakoot factors — but no number can promise a marriage. Compatibility is one part; the rest is the people. An honest reading tells you what the chart supports and where it stays silent.
