Given:

Final Balance = $160,000

rate = 8% or 0.08

Compounding period = daily = 365 days

time in years = 10

Find: Principal or Initial Amount

Solution:

To determine the principal or the initial amount to be invested in order to have $160,000 at the end of 10 years with the given compounding rate, we have the formula below:


P=(F)/((1+(r)/(m))^(mt))

where:

P = Principal

F = Final Value = $160,000

r = annual rate = 0.08

m = compounding period = 365 days

t = time in years = 10

Let's plug into the formula above the given information.


P=(160,000)/((1+(0.08)/(365))^(365*10))

Then, solve for P.

a. Add the terms inside the parenthesis and multiply its exponent.


P=(160,000)/((1.000219178)^(3,650))

b. Apply the exponent to the term in the denominator.


P=(160,000)/(2.22534585)

c. Divide the numerator by the denominator.


P\approx71,898.94

Answer:

Therefore, one must invest $71,898.94 in order to produce a final balance of $160,000 at the end of 10 years given that the rate is 8% compounded daily.
