It will take 12.5 years to double the amount of $100,000 with a rate of 8%. Simple interest is a way to figure out how much interest will be charged on a sum of money at a specific rate and for a specific duration of time. Unlike compound interest, which adds the interest from the principal of prior years to determine the interest of the following year, the principal amount in simple interest remains constant. Given,What is simple interest?
Principle amount = $100,000
Rate of interest (R) = 8%
Let's say it takes T years then,
Principle amount + Interest = 2 × Principle amount
P + PRT/100 = 2 × P
100000 + 100000×8×T/100 = 200000
8000T = 100000
T = 12.5 years.
Hence "It will take 12.5 years to double the amount of $100,000 with a rate of 8%".
