Manglik dosha is one of the most-checked factors in Indian marriage astrology. The calculation looks at where Mars sits relative to three reference points in the chart — the Ascendant (Lagna), the Moon, and Venus — and flags afflicting house positions. Astrolium's free Manglik dosha calculator runs the full check on the Swiss Ephemeris with Lahiri ayanamsa and lists the cancellation factors that apply to your chart, no signup required.
The cultural weight of the dosha varies widely across regions and families. Some treat it as a serious bar to marriage; others use it as a starting point for discussion. The calculator gives the technical result and the reasoning behind it; what to do with that result is a separate conversation.
What the calculator returns
The output has four parts. Severity is the headline — none, partial, or full. Mars positions show the house from each of the three reference points, with afflicting houses (1, 2, 4, 7, 8, 12) flagged. Cancellation factors list every classical rule that applies — Mars exalted, Jupiter aspect, own-sign placement, and others. Interpretation translates the technical result into a few sentences about how the placement typically plays out.
Three reference points are checked. Mars from the Lagna affects the 7th house of marriage directly. Mars from the Moon affects emotional security in partnership. Mars from Venus affects romantic and sensual expression. A chart that is Manglik from only one reference point is read as milder than one where Mars afflicts from two or three.
The six afflicting houses
Mars in any of these six houses from the reference point produces the dosha:
| House | What it rules | How Mars plays |
|---|---|---|
| 1st | Self, body | Projects Mars onto the partner; reads as dominant |
| 2nd | Family, speech | Friction around in-laws or financial speech |
| 4th | Home, mother | Domestic conflict, restless household |
| 7th | Marriage | Direct affliction; assertion in partnership |
| 8th | Intimacy, joint resources | Tension around shared finances or sexuality |
| 12th | Bed pleasures, loss | Affects marital privacy and rest |
The 7th house is the most heavily-weighted because of its direct rulership of marriage. The 8th and 12th — which together with the 7th make up the marital and intimacy axis — are read as next-most significant. The 1st, 2nd, and 4th are included because of their indirect bearing on partnership through the chart's domestic and self-presentation layers.
Cancellation rules in plain language
Classical Vedic texts list dozens of conditions under which Manglik dosha is cancelled or significantly reduced. The major ones:
- Mars in own sign — Aries or Scorpio. Mars is comfortable here and expresses his nature without the friction that comes from being placed in a sign that does not suit him.
- Mars exalted in Capricorn — Mars in his sign of exaltation operates at peak strength and disciplined expression; classical texts treat this as a major cancellation.
- Jupiter aspect on Mars — Jupiter's benefic 5th, 7th, or 9th aspect softens Mars and is read as a strong mitigating factor.
- Both partners Manglik — when both charts share the status, the dosha is traditionally cancelled in full. This is the rule that most often resolves the marriage question in practice.
- Mars in own nakshatra — Mrigashira, Chitra, or Dhanishta. Similar to own-sign, the placement is read as well-supported.
- Mars in 2nd house in mutable signs, 4th in Cardinal, 7th in dual, or 12th in fixed — house-by-house refinements where Mars's nature aligns with the sign quality of the house.
Astrolium surfaces the factors that apply to your specific chart in the result panel, so you can see why the severity reading is what it is.
Pair with Kundli matching
The standalone Manglik check is the right tool for understanding one chart. For marriage compatibility specifically — where the partner's status interacts with yours — use the Kundli matching calculator. Kundli matching adds the partner's Manglik status to the 36-point Ashta Koota score and applies the same-status cancellation rule automatically.

How seriously to take the result
The honest framing: Mars-marked relationships often need more direct communication, more space for autonomy, and more patience around conflict. The cancellation rules exist in classical texts precisely because the placement is workable. Many long marriages involve Manglik partners. The calculator gives the technical result and the reasoning; the weight you give it is a personal, family, and cultural decision.
