how much do you need to invest in an account earning an annual interest of 5% compounded monthly, so that your money grows to $10000 in 3 years?

To find out how much you need to invest now (the present value $ P $) so that it grows to $10,000 in 3 years with an annual interest rate of 5% compounded monthly, you can use the formula for compound interest:

\[
A = P \left(1 + \frac{r}{n}\right)^{nt}
\]

Where:
- $ A $ is the amount of money accumulated after $ n $ years, including interest ($10,000 in this case).
- $ P $ is the principal amount (the initial investment).
- $ r $ is the annual interest rate (5% or 0.05).
- $ n $ is the number of times that interest is compounded per year (12 times for monthly compounding).
- $ t $ is the time the money is invested for, in years (3 years).

We need to solve for $ P $:

\[
P = \frac{A}{\left(1 + \frac{r}{n}\right)^{nt}}
\]

Substituting the given values:

\[
P = \frac{10000}{\left(1 + \frac{0.05}{12}\right)^{12 \times 3}}
\]

Let's calculate this.You need to invest approximately **$8,609.76** today to grow your investment to $10,000 in 3 years with an annual interest rate of 5% compounded monthly.
