What happens if the interest rate is 0%?

When the interest rate is 0%, no interest accrues and the monthly payment equals the total principal divided equally by the number of months (PMT = P / n).

What is the difference between loan principal and total payment?

The principal is the initial amount borrowed. Total payment is the principal plus all interest accrued over the duration of the loan.

Frequently Asked Questions

Monthly payments are calculated using the standard reducing-balance amortization formula, where each installment covers the monthly interest accrued on the remaining balance plus a portion of the principal.

Standard Reducing-Balance Amortization Formula

PMT = P \cdot \frac{r(1 + r)^n}{(1 + r)^n - 1}

PMT = P * [ r(1 + r)^n ] / [ (1 + r)^n - 1 ], where PMT = periodic monthly payment, P = principal borrowed, r = monthly periodic interest rate (Annual Rate / 12), n = total number of monthly payments. If rate is 0%, PMT = P / n.
