Step 1
Gather the following information: payments for the annuity, interest rate on annuity and the period of the annuity. For example, you have to pay an annual lease of $10,000 for the next 10 years at a rate of 5 percent.
-
Step 2
Calculate the future value of the ordinary annuity with the following formula: Payment x (((1+interest rate)^term -- 1)/interest rate). In the example above, the future value of the ordinary annuity is $62,889: $5,000 x (((1+.05)^10 - 1)/.05).
-
Step 3
Multiply future value of the ordinary annuity by 1 plus the interest rate to get the future value of the annuity due. In our example, this would be $66,033.94 ($62,889 x 1.05).
