About the calculator catalogue.

PaisaMath offers 30+ free calculators across investing (SIP, lumpsum, step-up, goal, inflation-adjusted), savings (FD with monthly payout and after-tax view), home loans (EMI, eligibility, prepayment, down payment, on-road price for cars), and goal planning (retirement corpus, child education). Bank-branded and amount-preset landing pages take the total to 100+ URLs.

Yes. Every calculator is completely free, with no paywalls, no premium tiers, no ads gating answers, and no sign-up. Open the page, enter your numbers, get your answer.

Calculations use the same compound-interest and amortisation formulas your bank or mutual fund house uses. Projections assume the inputs you provide hold over the full duration – actual returns from market-linked investments (SIPs, lumpsums) will vary year to year. For loan EMIs the math is exact; for FDs the interest is computed at quarterly compounding (the Indian regulatory standard).

For monthly mutual fund investments, use the SIP Calculator. For a one-time mutual fund investment, use Lumpsum. For a home loan, use Home Loan EMI (and Home Loan Eligibility if you're working out how much you can borrow). For a fixed deposit, use the FD Calculator. If you have a target amount in mind (corpus for retirement, child education, down payment), use the Goal SIP Calculator to reverse-solve the monthly SIP you need.

A few math layers most Indian calculators skip: inflation-adjusted SIP projections (today's rupees, not future-value rupees), prepayment simulators with month-by-month amortisation, on-road price that adds RTO and TCS to ex-showroom so loan EMI matches the cheque, step-up SIP for SIPs that grow with your salary, and goal-anchored reverse-solve for retirement, education, and down payment targets.
