How this is worked out
Compares the effective tax rate and liability under both regimes based on your deductions.
The formula behind it:
Tax (Old) vs Tax (New)
| Symbol | What it means |
|---|---|
IT (O) |
Income Tax under Old Regime |
IT (N) |
Income Tax under New Regime |
Nothing is rounded away quietly and nothing is assumed on your behalf. If a figure appears in the result, it came from something you entered.
A worked example you can follow
Evaluating tax at ₹12L income with ₹2L deductions.
Change any one input and watch the result move — that sensitivity is the real lesson. It is far more useful than memorising a single outcome, because your own rate, tenure or contribution will never match the example exactly.
