Notes

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%.
