$3,031 is the Estimated monthly investment to get $250,000 at 12% compounded monthly over 5 years

Step-by-step explanation

Given information's are

Estimated investment= $250,000

Year = 5 years

Interest Rate = 12% compounded monthly

Compound interest = ((P×(1+i)^n) - P)

where P = Principal

I is the annual interest rate, and

n is the number of periods

Compound interest = (( $250,000 ×(1+12÷100)^5) - $250,000)

Compound interest = $68,156.18

Monthly investment needed = Estimated investment - Estimated interest

= $250,000 - $68,156.18 = $181,843.82 ÷ 60 (months) = $3,031


= $250,000 - $68,156.18 = $181,843.82 ÷ 60 (months) = $3,031

Estimated monthly investment to get $250,000 at 12% compounded monthly over 5 years is $3,031
