Reference

To calculate the loan amount we use the following formula:

P = (A / Rate) × { 1 − (1 + Rate) − N }

Where:

P = The loan amount ,

A = The monthly loan payment ,

N = The number of monthly payments (for a 3 year loan N = 3 x 12 = 36) ,

Rate (monthly interest rate) = Decimal Rate / 12 , or Rate = (Annual Interest Rate / 100) / 12

You can also try this calculator to estimate how much your car will be worth after a number of years.
