Open Compound Interest CalculatorCompound interest is interest calculated on both the initial principal and the accumulated interest from previous periods. It makes your money grow faster than simple interest.
More frequent compounding (daily vs annually) yields slightly higher returns because interest starts earning interest sooner. The difference is more noticeable with higher rates and longer periods.
The Rule of 72 estimates how long it takes to double your money: divide 72 by the interest rate. At 8% interest, money doubles in approximately 9 years (72/8 = 9).
