How to Calculate a $40,000 Loan Payment

The monthly payment formula uses the principal amount, annual interest rate, and loan term in months:

Monthly payment formula:
M = P × [r(1+r)^n] / [(1+r)^n − 1]
P = principal · r = monthly rate · n = number of payments
Example: $40,000 at 7% for 36 months
Monthly rate r = 7% ÷ 12 = 0.005833
Monthly payment = $1,235.08
Total interest = $4,463.02
