Compound interest is the accrual of interest on both the initial investment amount and on the interest earned over the previous years of the investment, ie. For example, after making a deposit, interest for the first year is accrued on the initial amount invested. In the second year, interest is accrued on the initial amount deposited and on the interest received in the previous year. In the third year, interest is accrued on the initial deposit and all the interest previously received. Assuming you’re asking how much interest you’ll earn on your savings account balance, the answer depends on the account’s interest rate and how much money is in the account.

  • “Interest on interest,” or the power of compound interest, will make a sum grow faster than simple interest, which is calculated only on the principal amount.

That amount then accrues interest over each quarter until the end of the three years. It compounds according to the compound interest formula eleven times. Recall that the exponent on that formula is the number of compounding periods. Now let’s take a look at what happens at the end of the second quarter.
