Final answer:
To calculate the future value of an investment with compound interest, we can use the formula FV = P(1 + r/n)^(nt). In this case, John's $1,000 investment at an interest rate of 4.8% compounded monthly will be worth approximately $1,048.64 after 1 year.
Step-by-step explanation:
To calculate the future value of an investment with compound interest, we can use the formula:
FV = P(1 + r/n)^(nt)
Where:
- FV is the future value
- P is the principal amount (the initial investment)
- 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 the money is invested for
In this case, John's initial investment is $1,000, the interest rate is 4.8% (or 0.048 as a decimal), and the interest is compounded monthly (so n = 12). We want to calculate the future value after 1 year, so t = 1.
Plugging these values into the formula:
FV = 1000(1 + 0.048/12)^(12*1)
Calculating the result:
FV ≈ $1,048.64
