Divide your interest rate by the number of payments you’ll make in the year (interest rates are expressed annually). So, for example, if you’re making monthly payments, divide by 12. 2. Multiply it by the balance of your loan, which for the first payment, will be your whole principal amount.
How do you calculate interest annually?
A = P(1 + r/n)nt
- A = Accrued amount (principal + interest)
- P = Principal amount.
- r = Annual nominal interest rate as a decimal.
- R = Annual nominal interest rate as a percent.
- r = R/100.
- n = number of compounding periods per unit of time.
- t = time in decimal years; e.g., 6 months is calculated as 0.5 years.
