Salary calculators

The previous chapter works one salary through by hand. This one does it with your numbers.

Everything here applies the FY 2026-27 rules set out in Old regime vs new regime and EPF, EPS, Form 11 and gratuity: the seven-slab new regime with its ₹60,000 rebate and marginal relief, the four-slab old regime, surcharge with marginal relief, and 4% cess. Nothing is sent anywhere; it all runs in your browser.

What the first calculator is doing

It splits your CTC the way an Indian payroll does, then taxes the result twice (once under each regime) and reports the monthly credit to your bank account under both.

• Basic defaults to 50% of CTC, the floor the Labour Codes have required since 21 November 2025.
• Employer PF, gratuity provision, employer NPS and insurance premiums are subtracted from CTC before the special allowance is worked out, because none of them reach your bank account.
• Employer NPS is excluded from taxable salary in both regimes, up to 14% of Basic, under Section 124(2).
• HRA exemption is the least of actual HRA, rent minus 10% of Basic, and 50% or 40% of Basic. It applies only in the old regime.
• Break-even is solved numerically: the deduction total at which the old regime produces exactly the new regime's tax. Claim more than that and the old regime wins.

What it deliberately does not model

Variable pay and joining bonuses, which are taxable in the year received and distort a monthly figure. Capital gains, including RSU sales, which are taxed separately and may trigger advance tax. Perquisites valued under the Rules, such as an employer-provided car or accommodation. And any state's professional tax other than the figure you enter.

Treat the output as an estimate accurate to the rules, not a payslip. Where a number matters, check it against the numbers page and your own Form 130.
