## The Formula to Calculate Simple Interest Rate

The simple interest formula is I = PRT

I is the amount of interest expressed as a dollar value

P is the principal

R is the annual rate of interest

T is the loan term expressed in years or a fraction of a year

For example, if you borrow \$5,000 at a 5 percent annual interest rate for one year, you’ll pay \$5,250 — \$5,000 x 0.05 x 1 — on the maturity date.

In the same way, if you borrow \$3,000 at a 5 percent annual interest rate for six months, you’ll pay \$3,075 — \$3,000 x 0.05 x 6/12 — on the maturity date.

The formula is P/loan term in months.

The monthly payment on a 12-month, \$5,000 loan will be \$5,000/12 or \$416.67 each month.

The monthly payment on a six-month, \$3,000 loan will be \$3,000/6 or \$500 each month.

The monthly interest on a \$5,000 loan at a 5 percent annual interest rate for one year will be \$5,000 x 0.05 x 1/12 or \$20.83.

The monthly interest on a \$3,000 loan at a 5 percent annual interest rate for six months will be \$3,000 x 0.05 x 1/12 or \$12.50.

Add the monthly principal and interest payment to get the monthly loan payment:The monthly loan payment on a \$5,000 at a 5 percent annual interest rate for one year will be \$416.67 + 20.83 or \$437.50.The monthly loan payment on a \$3,000 at a 5 percent annual interest rate for six months will be \$500 + \$12.50 or \$512.50.
