About the Old vs New Tax Regime Calculator
"Old regime or new regime, which is better" is one of the most debated questions every tax season, and the honest answer is: it depends entirely on how many deductions you actually claim. This calculator does the comparison for you — enter your income, your 80C/80D-style deductions, and home loan interest if any, and it computes your tax liability under both regimes side by side.
The new regime offers lower slab rates and a flat ₹75,000 standard deduction, but no other exemptions or deductions. The old regime has higher rates but lets you subtract things like Section 80C investments (PPF, ELSS, insurance premiums, up to ₹1.5 lakh), 80D health insurance premiums, HRA exemption, and home loan interest under Section 24 — so if your combined deductions are large enough, the old regime can still work out cheaper despite the higher rates. As a rough rule of thumb, if your total deductions (excluding standard deduction) exceed roughly ₹3.5-4 lakh, the old regime often starts winning — but the exact crossover point depends on your income level too, which is exactly why a side-by-side calculation beats a rule of thumb. Run this whenever your deductions change meaningfully, such as after taking a new home loan or increasing your 80C investments.
