**Formula**

The formula for calculating the monthly car note is derived from the standard formula for a fixed-rate loan:

$M=P×((+r)n−r×(+r)n )$

Where:

- $M$ is the monthly payment.
- $P$ is the loan amount.
- $r$ is the monthly interest rate (annual rate divided by 12).
- $n$ is the total number of payments (loan duration in years multiplied by 12).

Let’s consider a scenario where you borrow $20,000 for 5 years with an annual interest rate of 4.5%.

$M=20000×((+)5×12−×(+)5×12 )$

After calculating, the monthly car note would be displayed.
