Income Tax Old Regime Calculator (2025-26)

How this calculator works

It takes your gross salary, subtracts the standard deduction and any exemptions and deductions you're eligible for — HRA, home loan interest, 80C investments, 80CCD contributions, mediclaim, and donations — then applies old-regime slab rates plus the Section 87A rebate and 4% health & education cess to arrive at your final tax.

Using it:

Enter your gross salary — the standard deduction is applied automatically.
Fill in exemptions such as HRA and home loan interest, and any other deductions that apply.
Add your 80C investments and 80CCD (NPS) contributions.
Read your taxable income, rebate, and final net tax in the summary panel.
