Find how much money needs to be deposited now into an account to obtain [tex]$4,100 (Future Value) in 15 years if the interest rate is 6% per year compounded annually.

Round your answer to 2 decimal places.

The final amount is $[/tex] _______


Sagot :

Certainly! To determine how much money needs to be deposited now (the present value) in order to obtain [tex]$4,100 after 15 years with an annual interest rate of 6%, we use the formula for the present value of a future sum of money. This formula is derived from the compound interest formula and can be expressed as: \[ PV = \frac{FV}{(1 + r)^n} \] where: - \( PV \) is the present value (the amount of money to be deposited now), - \( FV \) is the future value (the amount of money to be received in the future, which is $[/tex]4,100 in this case),
- [tex]\( r \)[/tex] is the annual interest rate expressed as a decimal (6% or 0.06 in this case),
- [tex]\( n \)[/tex] is the number of years the money is invested (15 years in this case).

Let's break down the calculation step-by-step:

1. Start with the future value (FV), which is [tex]$4,100. 2. Use the annual interest rate (r), which is 6% or 0.06. 3. Identify the number of years (n), which is 15 years. 4. Plug these values into the present value formula: \[ PV = \frac{4100}{(1 + 0.06)^{15}} \] 5. Add the interest rate to 1: \[ 1 + 0.06 = 1.06 \] 6. Raise 1.06 to the power of 15: \[ 1.06^{15} \approx 2.39656 \] 7. Divide the future value by this compounded factor: \[ PV = \frac{4100}{2.39656} \] 8. Perform the division: \[ PV \approx 1710.79 \] So, the amount of money that needs to be deposited now to obtain $[/tex]4,100 in 15 years with a 6% annual interest rate, compounded annually, is approximately $1,710.79.
