Compound Interest Formula & Explanation
The Formula for Compound Interest
A = P(1 + r/n)<sup>nt</sup>
Where:
- A = future value
- P = initial deposit
- r = annual rate (as a decimal)
- n = number of times interest is compounded per year
- t = number of years
What Is the Time Value of Money?
Money today is worth more than the same amount in the future. That’s why compound interest works—it lets your money earn interest on top of interest.
What Is the Compound Annual Growth Rate (CAGR)?
CAGR shows the average annual rate of return over time. It smooths out the highs and lows.
Interest Calculation for 5 Years (Example)
Let’s say you invest $5,000 at a 5% annual interest rate, compounded monthly, with $200/month added. In 5 years, your savings can grow to over $20,000.
Additional Contributions and APY
Compounding with Additional Contributions
When you make regular deposits, the compound interest calculator adjusts the math. Your total grows faster, especially when interest compounds frequently.
Savings Account and APY Considerations
A high-yield savings account often has better APY than a regular one. Be sure to check the annual percentage yield before you invest.
What Is the Effective Annual Interest Rate (APY)?
It’s the real rate you’re earning after compounding—use this rate before compounding when comparing options.
