To calculate the initial deposit needed to have $2000 in the account in 10 years with 5% interest compounded quarterly, we can use the formula for compound interest:
A = P(1 + r/n)^(nt)
Where:
- A is the future value (in this case, $2000)
- P is the principal amount (the initial deposit we want to find)
- r is the annual interest rate (5% or 0.05)
- n is the number of times interest is compounded per year (quarterly, so 4)
- t is the number of years (10)
Rearranging the formula to solve for P, we get:
P = A / (1 + r/n)^(nt)
Substituting the values into the formula, we have:
P = 2000 / (1 + 0.05/4)^(4*10)
Calculating this equation gives us the value of P, which is approximately $1,308.69.
