"Accurate" can mean two different things here. Is the calculation correct? And does the score predict how a marriage will go? The first has a clear answer. The second does not, and a trustworthy site should say so plainly.
Is the calculation correct?
It can be, and you can check it. The inputs are astronomical facts: where the Moon was in the sky, at a given time and place. From there the method is a set of fixed lookup tables written down centuries ago. Given the same inputs, same tables and same ayanamsa, any correct calculator returns the same number.
Where calculators differ, the difference is traceable:
- Ayanamsa. The offset between the tropical and sidereal zodiac. Lahiri is the Indian standard. Others shift the Moon by a fraction of a degree, which matters only near a nakshatra boundary.
- Birth time. An error of an hour or two can move the Moon into another nakshatra. This is the biggest practical source of wrong results. Read how to find your birth time.
- Table conventions. Tara and Varna are counted slightly differently across sites, and the boy-and-girl asymmetry is handled in different ways.
- Place. Birth place sets the local time and the ascendant, which matters for Manglik but not for the Moon-based score.
If two sites give you different totals, the cause is usually one of these four. We show every koota with its points so you can compare line by line, and we use the classical tables, not a number tuned to match any other site.
Does the score predict a marriage?
There is no evidence that it does. We are not aware of any controlled study showing that couples with higher guna scores have longer or happier marriages, and astrology is not accepted as a predictive science. What the tradition offers is a structured conversation, a shared ritual that families have used for a very long time, and a way to line up some rough questions: temperament, health, family fit.
That does not mean it is worthless to you. Many people find the process meaningful. It gives families a common language and a reason to talk about differences. What the evidence does not support is treating a score as a verdict.
What the score can honestly tell you
- Whether a pair clears the traditional bar. That is a fact about the tables, not about you.
- Which specific points were lost, and whether a named dosha is involved.
- Where a pandit might want to look further, which is why our result ends with questions you can take to one.
What it cannot tell you
- How well you communicate when you disagree.
- Whether you share views on money, children, work or where to live.
- Anything about health, fertility or longevity.
- Anything about the other person's character.
Fear-based claims, such as "this match will fail" or "this couple will face loss," are beyond what any table can support. We do not write them, and we do not sell remedies.
How to use it sensibly
- Run the match, and check that the birth times are right. If one is unknown, use matching without a birth time so the uncertain parts are marked.
- Read the doshas and their cancellation rules, not only the total. How kundli matching works explains why.
- If the score is low, read what next after a low guna score before reacting.
- Spend more time on the conversations that no chart covers. If you are already together, the guide on kundli matching for a love marriage covers when it is worth running at all.
A fair way to hold it
Treat the score as one input, the way you might treat a family tradition: worth understanding, worth respecting if it matters to the people you love, and not a substitute for knowing the person. If your families care about it, the honest approach is to get the number, understand what it measures and decide together how much weight to give it.
Check yours
Use the matching form to see every koota, every dosha rule and every point. The working is shown, so you can check it against any other source. Birth details are never kept on our servers.
