You need to know the principal amount, the rate and the time. Then a very simply formula for calculating interest is I = PRT where P is the principal amount, R is the interest rate and T is the period of time in years.

What is simple interest?

Simple interest does not compound. In other words, If you start off with $500 and get $5 in interest, the $5 you got in interest will not be included when calculating the amount of interest you will get next year. Simple interest can be calculated by the formula i = prt, where i is the amount of money earned from the interest, p is the principle (starting money), r is the rate (as a decimal,) and t is the time in years. Another formula is used to calculated the accumulated amount: A = p(rt + 1), where A is the accumulated amount.

How many years does steven need to invest his 3000 at 7 percent tp earn 210 in simple interest?

Answer : 1 year The formula for calculating simple interest is I = PRT/100, where I = Interest, P = Principal Amount, R = Rate of Interest, T = Time. Then, 210 = 3000 x 7 x T/100 : 21000 = 21000T : Then T = 21000/21000 = 1
