In which E is the amount of interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.

Compound interest:

The compound interest formula is given by:

Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.

Total amount in compound interest:

$3,000 in a certificate of deposit that pays 2.8% interest, compounded annually for 4 years. This means, respectively, that

So

Total amount in simple interest:

So
