Compounding rate of interest

Generally, simple interest paid or received over a certain period is a fixed percentage of the principal amount that was borrowed or lent. For example, say a student obtains a simple-interest loan to pay one year of their college tuition, which costs $18,000, and the annual interest rate on their loan is 6%. For periodic compounding, the exact doubling time for an interest rate of r percent per period is t = ln ⁡ (2) ln ⁡ (1 + r / 100) ≈ 72 r {\displaystyle t={\frac {\ln(2)}{\ln(1+r/100)}}\approx {\frac {72}{r}}}, where t is the number of periods required. The formula above can be used for more than calculating the doubling time.
