The formula to calculate the initial deposit required to accumulate a certain future value with compound interest is:
Amount=P(1+rn)nt
Where:
Assuming you want to accumulate $5000 in 7 years with an annual interest rate of 5%, you would use the formula as follows:
5000=P(1+0.051)1×7
Rearranging to solve for P:
P=5000(1+0.05)7
So, the initial deposit P is:
P=50001.057≈3553.41
Therefore, you need to deposit approximately $3553.41 to accumulate $5000 in 7 years with a 5% annual interest rate.
