Answer:
$4,739.34
Explanation:
Step one :
Given data
final amount $1,000,000
initial principal balance??
annual interest rate=7%
time (in years)=30 years
Step two:
Applying the
Simple interest Formula
A = P (1 + rt)
A =final amount
P =initial principal balance?
Let us set this as x
r =annual interest rate
t =time (in years)
Step three :
Plugin our data into the formula We have
1,000,000=x(1+7*30)
1,000,000=x(1+210)
1,000,000=x(211)
Opening bracket we have
1,000,000=211x
Divide both sides by 211 we have
1,000,000/211=x
$4,739.34
Hence the money you have to invest today at a 7% annual interest rate compounded daily to reach your goal in 30 years
Is $4,739.34
Use the compound interest formula.
Let A = the ending amount
Let P = the principal
Let r = the interest rate
Let n = the amount compounded a year
Let t = time
A = P(1 + r/n) ^(n/t)
Substitute your numbers in
1,000,000 = P(1 + .07/365)^(365/30). Divide each side by (1 + .07/365)^(365/30).
365 / 30 = 10,950
1,000,000/(1 + .07/365)^(10,950) = P. Calculate your value for P.
$122,481.09 = P
