The desired future accumulated amount is 120,000 after 7 years invested in an account with 7% interest compound quarterly. How much should you invest presently.

We can use the formula for compound interest to solve for the present value:

A = P(1 + r/n)^(nt)

where A is the future value, P is the present value, r is the annual interest rate, n is the number of times the interest is compounded during the year, and t is the number of years.

In this case, we have:

A = 120,000
r = 7% = 0.07
n = 4 (quarterly compounding)
t = 7

So we can solve for P:

P = A / (1 + r/n)^(nt)
P = 120,000 / (1 + 0.07/4)^(4*7)
P = 78,313.61

Therefore, you should invest $78,313.61 presently to accumulate $120,000 after 7 years invested in an account with 7% interest compound quarterly.

To calculate the present amount you should invest to reach a desired future accumulated amount, we can use the formula for compound interest:

A = P(1 + r/n)^(nt)

Where:
A = Future accumulated amount
P = Present amount
r = Annual interest rate (as a decimal)
n = Number of times interest is compounded per year
t = Number of years

In this case, we have:
A = $120,000
r = 7% = 0.07 (as a decimal)
n = 4 (since interest is compounded quarterly)
t = 7 years

We need to solve for P.

120,000 = P(1 + 0.07/4)^(4*7)

Simplifying the right side of the equation:
120,000 = P(1.0175)^(28)

Next, divide both sides by (1.0175)^(28):

P = 120,000 / (1.0175)^(28)

Using a calculator, we find that (1.0175)^(28) is approximately 1.135.

P = 120,000 / 1.135 ≈ $105,538.61

Therefore, you should invest approximately $105,538.61 presently to reach a desired future accumulated amount of $120,000 after 7 years.
