SNSM Tools offers a comprehensive suite of financial calculators tailored for Indian users. Our EMI Calculator uses the standard reducing-balance formula approved by RBI to compute monthly loan instalments for home loans, car loans, and personal loans, along with a complete amortisation schedule.
The SIP Calculator projects mutual fund returns using the standard future value formula for recurring investments, showing year-wise growth with a stacked chart. The FD Calculator supports all compounding frequencies — monthly, quarterly, half-yearly, and annually — to match real bank FD products.
Our Income Tax Calculatorcovers FY 2024-25 with the new regime's revised slabs (including the ₹75,000 standard deduction) and the old regime with common deductions (80C, 80D, HRA), automatically comparing both to show which saves more tax. The GST Calculator handles both exclusive (adding GST) and inclusive (extracting GST) calculations across all four GST slabs: 5%, 12%, 18%, and 28%.
The HRA Calculator applies the three-condition minimum rule under Section 10(13A), distinguishing between metro (50%) and non-metro (40%) cities. The PPF Calculator uses the current government rate of 7.1% with annual compounding over the 15-year lock-in. Finally, our Age Calculator computes exact age accounting for leap years and varying month lengths, with bonus stats like total days, weeks, hours lived, and next birthday countdown.
All calculators are free, require no login or registration, and run entirely in your browser — no data is sent to our servers. Calculations happen instantly as you adjust inputs, and every tool is fully optimised for mobile devices.
