The formula for calculating the future value of an annuity due (where a series of equal payments are made at the beginning of each of multiple consecutive periods) is: P = (PMT [((1 + r)n – 1) / r])(1 + r) Where: P = The future value of the annuity stream to be paid in the future.
How does the future value of annuity due formula work?
An annuity due is sometimes referred to as an immediate annuity. The future value of annuity due formula calculates the value at a future date. The use of the future value of annuity due formula in real situations is different than that of the present value for an annuity due.
