$110 is the future value of $100 invested for one year at 10%, meaning that $100 today is worth $110 in one year, given that the interest rate is 10%. In a nutshell, long-term returns from stocks, exchange-traded funds (ETFs), or mutual funds are technically called compound earnings. However, it can still be calculated in the same manner if you know your expected rate of return. Compound interest is calculated by applying an exponential growth factor to the interest rate or rate of return you’re using. The good news is that there are plenty of excellent calculators that will do the math for you.
Simple Interest versus Compound Interest
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. Now, you deposit $135 again, but this time, this deposit will accrue interest using the compound interest formula ten times. The process repeats until at the end of three years, you deposit your last $135 that will not accrue interest since you are depositing it on the same day you are checking the balance in your account. Remember also that, because you are compounding quarterly, the annual rate must be divided by four since your deposits are earning interest every quarter. The compounding frequency, which is the time period at which interest is added to the principal, can have a slight positive effect on the effective interest rate versus the nominal annual interest rate.
