Compound Interest Calculator

Change any of the displayed values, and the calculator will automatically update the other values to account for compound interest and regular payments. (Equivalent to the Excel functions PV, FV, and PMT.)

Examples: Loan | Savings | Retirement | Investment | Endowment

Save or share your custom scenario pictured above:


The calculator automatically computes whichever value you least recently updated: present value, future value, or payment amount.

All interest rates shown are annual rates.

Interest is compounded once per payment (even if payment amount is $0).

Full precision is used internally, but displayed values are rounded to the nearest $1 and 0.01%.
