Frequently Asked Questions About Compound Interest
Compound interest is the interest calculated on the initial principal and also on the accumulated interest of previous periods. It's often called "interest on interest" and makes your money grow at a faster rate compared to simple interest. The formula for compound interest is: A = P(1 + r/n)^(nt), where:
- A = the future value of the investment
- P = the principal investment amount
- r = annual interest rate (decimal)
- n = number of times interest compounds per year
- t = number of years the money is invested
Compounding frequency significantly impacts your returns. The more frequently interest compounds, the higher your effective returns will be:
- Annual Compounding: Interest calculated once per year
- Semi-Annual: Interest calculated twice per year
- Quarterly: Interest calculated four times per year
- Monthly: Interest calculated twelve times per year
- Daily: Interest calculated 365 times per year
The Rule of 72 is a simple way to estimate how long it will take for an investment to double at a given annual interest rate. You simply divide 72 by the annual rate of return. For example:
- At 6% return: 72 ÷ 6 = 12 years to double
- At 8% return: 72 ÷ 8 = 9 years to double
- At 12% return: 72 ÷ 12 = 6 years to double
Regular contributions dramatically accelerate wealth creation through compounding. Here's why they're so powerful:
- Dollar-Cost Averaging: You buy more units when prices are low and fewer when prices are high
- Compounding on Contributions: Each contribution starts earning returns immediately
- Discipline: Regular investing builds financial discipline
- Long-term Growth: Small regular amounts grow into significant sums over time
