Final answer:
To have $10,000 in ten years in a bank account with an annual compounded interest rate of 10%, you need to deposit approximately $3855.43 today. This is calculated using the formula for present value of a lump sum.
Step-by-step explanation:
To determine how much money needs to be deposited into a bank account that pays 10% interest compounded annually to have $10,000 in ten years, we must calculate the present value of the $10,000. We do this by using the formula for the present value of a lump sum:
PV = FV / (1 + r)^n
Where:
PV is the present value (initial deposit needed).
FV is the future value (the amount we desire in the future).
r is the annual interest rate (expressed as a decimal).
n is the number of periods (years in this case).
Given that FV = $10,000, r = 10% or 0.10, and n = 10 years, we substitute these values into the formula:
PV = 10000 / (1 + 0.10)^10
Now, we calculate the value inside the parentheses first:
(1 + 0.10)^10 = (1.10)^10
Next, we calculate the power of 1.10:
(1.10)^10 = 2.59374
Finally, we divide $10,000 by 2.59374 to find the present value:
PV = 10000 / 2.59374
PV ≈ $3855.43
Therefore, you need to deposit approximately $3855.43 today to have $10,000 in your bank account after ten years, assuming the account pays 10% interest compounded annually.
