Step 3 Multiply by your car loan principal Multiply the number by the loan’s principal amount — the total amount of your car loan. Write this number down, as it will be used in your final calculation.

Step 5 Multiply sum by itself, using number of payments as exponent Take the sum from step 4 raised to the power of the number of months included in the term of your loan. For example, if you will make 36 monthly payments, multiply the sum from step 4 by itself 36 times.

Step 6 Calculate 1 divided by this sum Calculate 1 divided by the result from step of your multiplication.

Round this number to the nearest hundredths place to make it easier to work with.

Step 7 Subtract sum from 1 Subtract this number from 1. Jot this number down for use in your final calculation.
