How it works

How this calculator works

Enter your salary and other income, then the deductions you can claim (80C, 80D, NPS, home loan interest, HRA and more). The calculator shows slab-wise tax, rebate, surcharge and cess under both regimes side by side, which one saves more, and how much old-regime deduction you need before it beats the new regime.
