Finance
Loans, EMI, investments, tax and everyday money decisions.
Money questions usually come down to one of three things: what something will cost you each month, what a sum will grow into, or which of two options is better. The calculators here cover all three, from loan repayments and EMI schedules to SIP growth, tax and retirement planning.
Most of them share the same underlying arithmetic — a rate, a period, and a balance that changes as one is applied to the other. Understand how one works and the rest tend to follow.

What these calculators have in common
Assumptions worth knowing before you rely on any result here.
Rates are quoted in more than one way
A "12% loan" might mean 12% nominal compounded monthly, which works out to 12.68% effective across a year. Lenders quote whichever number flatters the offer. When comparing, compare APRs — they must include compulsory fees.
Compounding frequency changes the answer more than people expect
₹1,00,000 at 10% for 10 years grows to ₹2,59,374 compounded annually and ₹2,70,704 compounded monthly. Same rate, same period, about ₹11,000 apart.
Results exclude tax and inflation unless stated
A 12% return with 6% inflation is roughly 6% in real terms. For anything long-term, subtract expected inflation from the rate before you enter it, and remember interest is usually taxable in the year it is earned.
Shortening the term beats lowering the payment
When you prepay a loan, cutting the tenure stops interest accruing sooner. Cutting the monthly amount stretches the loan out and leaves total interest almost unchanged.
