Formula for interest rate percentage
The annual percentage rate (APR) of a loan is the interest you pay each year represented as a percentage of the loan balance. For example, if your loan has an APR of 10%, you would pay $100 annually per $1,000 borrowed. When you know the principal amount, the rate, and the time, the amount of interest can be calculated by using the formula: I = Prt. For the above calculation, you have $4,500.00 to invest (or borrow) with a rate of 9.5 percent for a six-year period of time. To find simple interest, multiply the amount borrowed by the percentage rate, expressed as a decimal. To calculate compound interest, use the formula A = P(1 + r) n, where P is the principal, r is the interest rate expressed as a decimal and n is the number of number of periods during which the interest will be compounded.

In the example shown, the formula in C10 is: = FV ( C6 / C8 , C7 * To use compound interest, you need to adjust several numbers. Change the annual rate to a monthly rate: 5% divided by 12 months becomes 0.004167. Next, convert the number of periods to 12. To calculate for more than one year, you’d use 12 per year. For example, four years would be 48 periods.

A percentage (the interest) of the principal is added to the principal, making your initial investment grow!
To calculate the periodic interest rate for a loan, given the loan amount, the number of payment periods, and the payment amount, you can use the RATE
R = Rate of Interest per year as a percent; R = r * 100 t = Time Period involved in months or years From the base formula, A = P(1 + rt) derived from A = P + I and I = Prt so A = P + I = P + Prt = P(1 + rt) Multiple the principle borrowed or invested (P) by the interest rate (r) and by the number of periods the interest is applied. For example: $100 at 8 percent for 10 years, with interest applied annually, will yield simple interest of $80. To find simple interest, multiply the amount borrowed by the percentage rate, expressed as a decimal. To calculate compound interest, use the formula A = P(1 + r) n, where P is the principal, r is the interest rate expressed as a decimal and n is the number of number of periods during which the interest will be compounded.
