Finance & Money

Money calculators in one place: loan and EMI payments, simple and compound interest, APY, plus discounts, tax, tips, unit price, and profit margin.

Frequently asked questions

What is the difference between simple and compound interest?

Simple interest is charged only on the original amount; compound interest is charged on the amount plus accumulated interest. Each has its own calculator here.

What does APY mean?

APY (annual percentage yield) is the real yearly return once compounding is included. The APY calculator turns a nominal rate and compounding frequency into the APY.

Are these financial calculators exact?

The math is exact for the numbers you enter, but real loans and accounts include fees and changing rates, so treat the results as estimates.
