See which tax regime costs you less
India offers two income tax regimes, the old one with deductions and the new one with lower rates but fewer deductions, and which is cheaper depends on your situation. This calculator compares your estimated tax under both from your income and deductions, so you can see which regime suits you.
Why there is no universal answer
The old regime rewards people who claim substantial deductions, for investments, insurance, home loan interest, rent; the new regime rewards those who claim few, with its lower rates. The break-even depends on how much you actually deduct: below a certain level of deductions the new regime wins, above it the old one does. That is why the choice is personal, and comparing both on your real numbers is the only way to know rather than following a rule of thumb.

Frequently Asked Questions
Which tax regime is better?
It depends on your deductions. The old regime rewards substantial deductions; the new one offers lower rates for those who claim few. The break-even is personal.
When does the new regime win?
When your total deductions are below the level at which the old regime’s deductions would save more than the new regime’s lower rates. The calculator finds this for your numbers.
What deductions matter?
Investments, insurance, home loan interest and rent among others, which the old regime allows and the new one largely does not.
Can I switch regimes?
The rules on switching depend on your income type and year; the calculator helps you decide which is cheaper, but confirm the switching rules for your case.
