Our mission
Money decisions in India are made harder than they need to be — by jargon, by cluttered apps demanding your phone number, and by calculators that hide their assumptions. PaisaTools exists to fix that: every tool here is free, loads in under a second, works on any phone, shows its exact formula, and never asks you to sign up.
Our methodology
We use the same standard formulas used by banks, AMCs and the Income Tax Department: reducing-balance EMI, monthly-compounded SIP maturity, quarterly-compounded FD maturity, and slab-wise tax computation including the Section 87A rebate, marginal relief, surcharge and cess. Rates that change — tax slabs, PPF and small savings rates — are updated whenever the government notifies changes (most recently checked against Budget 2026 and the Jul–Sep 2026 small savings notification).
What we are not
We are not financial advisors, and nothing on this site is investment, tax or legal advice. Calculators produce estimates based on your inputs; your bank, fund house or CA's computation is final. For personalised advice, consult a SEBI-registered investment advisor or a chartered accountant.
Privacy by design
All calculations run entirely in your browser. Nothing you type into any calculator is transmitted, logged or stored. See our privacy policy.
