An annuity is a series of equal payments made at regular intervals. Calculating the future value of an annuity allows you to determine the total value of the annuity at a future date. This can help you plan for retirement, savings goals, or other financial objectives. Here’s how to calculate the future value of an annuity:
How to calculate the future value of an annuity?
To calculate the future value of an annuity, you can use the formula:
FV = Pmt * ((1 + r)^n – 1) / r
Where:
FV = Future Value of the annuity
Pmt = Payment amount per period
r = Interest rate per period
n = Number of periods
Let’s break down the formula with an example. Suppose you invest $500 every month into an annuity for 10 years with an annual interest rate of 5%. The future value of this annuity can be calculated as:
FV = $500 * ((1 + 0.05/12)^(10*12) – 1) / (0.05/12)
After solving this equation, you will find the future value of your annuity.
