Understanding Compound Interest
1
Interest on Interest
Compound interest is the interest you earn on both your principal and the accumulated interest from previous periods.
2
Time is Your Ally
The longer your money is invested, the more time it has to compound, leading to exponential growth.
3
Frequency Matters
The more frequently interest is compounded, the faster your money grows, assuming the same annual rate.
4
Regular Contributions
Adding regular contributions significantly boosts the power of compounding.
5
Rule of 72
Estimate how long money takes to double by dividing 72 by the annual rate. For example, at 8%, money doubles in about 9 years (72÷8=9).
