Finding the Interest Rate of an Annuity
Perform the following steps to find the interest rate (
i
) of an annuity where the starting
principal (
p
) is 1,000, number of compounding periods (
n
) is 6, and the future value (
s
) is
2,000.
1.
On the Home screen, enter the equation
to solve for
p
.
2.
Enter the equation to solve for
n
.
3.
Enter the equation to solve for i using the
with
operator.
solve(s=p
†
(1+i)^n,i) | s=2000
and
p=1000
and
n=6
Result: The interest rate is 12.246%.
