Given:
Principal, P = 26500
term=5 years
Monthly payment, A = 695
Question: Find interest rate
Solution:
Unless there is a table available, there is no explicit formula to calculate interest. However, the interest rate can be solved for using the formula to calculate the monthly payment, as follows.

Substituting
P=26500
i=monthly interest rate to be found
A=monthly payment=695
n=5*12=60 months

Rearrange to give successive estimates of i by
I(i)=(695/26500)*((1+i)^60-1)/(1+i)^60
Try initial estimate of i=0.02 (2% per month)
I(0.02)=0.0182
I(0.0182)=0.01736
I(0.01736)=0.01689
....
Eventually we get the value to stabilize at i=0.016265, or
Monthly interest =
1.6265% (to four decimal places)
