Transcript/notes
Here is the formula for the future value of money, with the definitions for all of the variables. And here are the steps to setting the equation to solve for the interest rate, R.
As an example, let’s say that someone invests $2000 in an account, the interest is compounded quarterly, so 4 times per year. After 5 years, the account equals $2899.90. What is the interest rate?
Using the formula, we have r, the interest rate equals, 4, times the quantity $2899.90 divided by $2000, raised to 1 divided by 4 times 5, minus 1.
From this we have 4, times the quantity 1.4499 rounded off raised to 1 over 20, minus 1. Here are the calculations written out on the screen. And this calculates to .075, or 7.5% as the interest rate on the investment.
