Final answer:
To have a balance of $1,000 at the end of five years with a 4% interest rate compounded quarterly, you need to deposit approximately $819.40 today, using the compound interest formula.
Step-by-step explanation:
To determine how much must be deposited in an account today to have a balance of $1,000 at the end of five years with an interest rate of 4%, compounded quarterly, we can use the formula for compound interest:
P = A / (1 + r/n)(nt)
Where:
- P = the present value (the amount of money you must deposit today)
- A = the future value ($1,000)
- r = the annual interest rate (0.04 for 4%)
- n = the number of times interest is compounded per year (4 for quarterly)
- t = the number of years the money is invested (5)
Plugging in the values gives us:
P = $1,000 / (1 + 0.04/4)(4*5)
P = $1,000 / (1 + 0.01)20
P = $1,000 / (1.01)20
P = $1,000 / 1.21989
P ≈ $819.40
So, you would have to deposit approximately $819.40 today to have $1,000 in your account after five years, with a 4% interest rate compounded quarterly.
