How to Calculate Future Value of Growing Annuity?

Calculating the future value of a growing annuity can be useful for financial planning and investment decisions. A growing annuity is a series of increasing cash flows that occur at regular intervals. To calculate the future value of a growing annuity, you can use the formula:

Future Value of Growing Annuity = CF * ((1 + g)^n – 1) / (r – g)

Where:
– CF = Cash flow at the end of the first period
– g = Growth rate of the annuity
– n = Number of periods
– r = Discount rate

To simplify the calculation, you can also use financial calculators or spreadsheet software.
