EMICalcs is a free hub of 32 finance calculators built for India: loan EMIs, SIP and step-up SIP projections, income tax for FY 2026-27 (new vs old regime), PPF/EPF/NPS, FD/RD, salary CTC-to-in-hand, HRA, TDS, brokerage and more — plus side-by-side comparison tools like SIP vs lumpsum and rent vs buy.

Why I built it: every Indian finance calculator I found was either buried in ads, out of date on tax rules, or wanted a signup for a simple EMI number.

What I'm proud of:

Every calculator ships with automated math tests — the site won't build if a formula drifts more than 0.5% from verified values.

Tax rules are already current for FY 2026-27 (₹75,000 standard deduction, 87A rebate taking tax to zero up to ₹12L taxable).

Results are shareable as URLs or WhatsApp messages, and amortisation schedules export to CSV.

Any calculator can be embedded free on your own site with a single iframe.

Static site, no signup, no app, no paywall.

Which money decision should I build a calculator for next?
