This is what the calculation gives for the numbers you entered. It is an estimate, not advice, and it knows nothing about your situation beyond those numbers. Rules for India change on a published schedule; the effective date is shown on every rule-based tool.
How this is calculated
Compare two positions: yours, and someone earning exactly the threshold. The law will not allow the extra tax to exceed the extra income, so relief is the amount by which it otherwise would. At a hundred rupees over fifty lakh the raw surcharge is over a lakh, and relief cuts it to a few tens of rupees.

Frequently asked questions
- Is marginal relief automatic?
- It is part of the computation rather than something claimed separately, so a correctly filed return already reflects it. It is worth checking, because it is the item calculators most often get wrong.
