Compound interestis computed on the initial principal as well as on the interest earned by the principal over a specified period of time. Consider the following example: An investor invests $1,000 in a 5-year term deposit with an interest rate of 8% with the interest compounded annually. Th...
This formula applies if the investment is compounded annually, meaning we reinvest the money annually. For daily compounding, the interest rate will be divided by 365, and n will be multiplied by 365, assuming 365 days a year. So Ending Investment = Start Amount * (1 + Interest Rate / 3...
The interest rate, rr, is 6.8% (or 0.068 as a decimal) and is compounded annually, so n=1n=1. The time, tt, is 6, since we know he opened his account 6 years ago. Plug in the known values into the formula and solve for the missing variable, PP. 1,780.80=P(1+0.0681)1(6)...
Now suppose the interest is compounding continuously with a semi-annual interest rate. So if the investment yields 10% semi-annually, the annual compounding interest will be 20%. For convenience, add an individual term namely Number of Compounding Units Per Year. In the case of semi-annual com...
Suppose, for instance, you have two loans, each with an interest rate of 10%, and one compounds annually and the other twice yearly. Even though they both have a stated interest rate of 10%, the effective annual interest rate on the loan that compounds twice a year will be higher. ...

That's to compound once per year. More generally, if you want to compound n times per year, you use: 2.FV = P (1 + r / n)Yn Example Let's say you want to invest $1000 at 5% interest, compounded annually. At the end of ten years, your balance would be ...
