Built to be accurate
Every calculator uses the standard formulas banks, fund houses and the Income Tax Department use: reducing-balance EMI, compound growth for SIP and FD, quarterly compounding for RD, and the exact slab, rebate, surcharge and cess rules for income tax, including marginal relief.
The tax rules were last checked on 7 October 2026 against the Finance Act 2025, Budget 2026 and the Income-tax Rules 2026. Each calculator shows its full working so you can check every step.
Estimates, not advice
Results are for planning. Your bank’s EMI may differ by a rupee because of rounding, and your final tax depends on details such as capital gains or arrears that these calculators don’t cover. For filing, check with a chartered accountant or the official income tax portal.
Private by design
Everything is calculated on your device. Your salary, loan and investment figures are never sent anywhere.
Frequently asked questions
Are these calculators up to date for 2026?
Yes. The income tax calculator covers FY 2025-26 and Tax Year 2026-27 (the first year under the Income-tax Act 2025). Slabs and rebates are unchanged in Budget 2026; the HRA calculator includes the eight cities that get the 50% limit from 2026-27.
How accurate is the EMI calculator?
It uses the standard reducing-balance formula banks use. The result usually matches your bank to the rupee; small differences come from how a bank rounds or counts days in the first month.
Do I need to enter my PAN or any personal details?
No. You only enter amounts. Nothing is stored or uploaded, and there is no signup.
Can I use the results to file my return?
Use them to plan and to cross-check. When filing, rely on the income tax portal’s computation or a chartered accountant, as your return may include income these calculators don’t cover.
