Finance Calculators
17 free tools
Free calculators for India: GST, income tax (new regime), HRA, EMI, loan prepayment, SIP, FD, PPF, EPF, NPS, gratuity and CTC to take-home pay, each with a worked guide.
These calculators put numbers behind common money decisions in India: how much a loan costs, what a monthly SIP could grow to, how much tax you owe, and what your salary looks like after deductions. Each tool has a written guide that shows the formula, a worked example and the simplifications it makes, so you can judge how far to trust the result.
The set covers GST, income tax under the new regime for FY 2026-27, HRA exemption, EMI, loan prepayment and eligibility, SIP, lumpsum, fixed deposits, compound interest, mutual fund returns, PPF, EPF, NPS, gratuity and CTC to take-home pay. Results are estimates based on the assumptions you enter. Everything is calculated in your browser, and nothing you type is sent to a server.
