answer:
To calculate the amount that will be in your account when you retire, we can use the formula for compound interest:
A = P(1 + r/n)^(nt)
Where:
A is the final amount in the account
P is the principal amount (initial deposit)
r is the annual interest rate (as a decimal)
n is the number of times the interest is compounded per year
t is the number of years
Given:
P = $2000
r = 5.25% = 0.0525 (as a decimal)
n = 12 (monthly compounding)
t = 65 - 25 = 40 years
1. Plug in the values into the compound interest formula:
A = 2000(1 + 0.0525/12)^(12*40)
2. Simplify inside the parentheses:
A = 2000(1.004375)^(480)
3. Calculate the exponent:
A = 2000(2.42742962062)
4. Multiply the principal amount by the result:
A = $4,854.86
Therefore, when you retire at 65 years old, there will be approximately $4,854.86 in your account if you deposit $2000 and earn an annual interest rate of 5.25% compounded monthly.
