The short version
About this site
Most Indian alimony calculators multiply a salary by a number somebody made up. This one starts from what courts actually ordered, and shows its working.
Why it exists
If you search for an Indian alimony calculator you will find a dozen tools that take a salary, multiply it by a fixed percentage, and print a figure with no source and no range. Some of them still quote the Rs 500 monthly ceiling under Section 125, which was removed by amendment in 2001.
Meanwhile the actual answer is sitting in reported judgements that are public, free, and almost unreadable unless you already know how to read case law.
This site is an attempt to put those two things together: a figure you can get in ninety seconds, and the judgements it came from, one click away.
Three things done differently
Old awards are restated in today's money
An award of Rs 500 a month in 1985 reads like a rounding error and is quoted that way all over the internet. It is about Rs 8,100 a month now. Every rupee figure on this site carries its value in today's money, computed from annual consumer price data. We have not found another Indian maintenance site that does this, and it changes how most pre-2010 case law reads. The method is set out in full in our note on inflation.
The estimate is a range, not a number
Anyone quoting a single figure is overselling. Quantum is discretionary and the honest output is a band, with the reasoning shown line by line underneath.
The evidence is one click away
Every estimate comes with the reported judgements nearest your own facts, and each of those links to a page explaining it and to the full text on IndianKanoon. If you think the estimate is wrong, you can go and check.
What it is built from
292 reported judgements from the Supreme Court and nineteen High Courts, 1970 to 2026, covering Section 125 CrPC and its replacement Section 144 BNSS, Sections 24 and 25 of the Hindu Marriage Act, the Special Marriage Act, the Muslim Women (Protection of Rights on Divorce) Act 1986 and the Domestic Violence Act.
The whole dataset is public: browse it, or take it as JSON. There is also an MCP endpoint so an AI assistant can answer questions from cited judgements rather than from a forum post.
What it is not
It is not a law firm and it is not legal advice. Nobody here is acting as your lawyer. It is a research tool that got useful enough to publish. Read the terms before you rely on anything.
It is also free, with no advertising, no lead generation and nothing sold to anybody. There is no business model, which is worth knowing when you are weighing whether to trust a figure.
