Compounding Formula:
| From: | To: |
Compound interest is interest calculated on the initial principal and also on the accumulated interest of previous periods. It causes wealth to grow faster than simple interest because you earn interest on interest.
The calculator uses the compounding formula:
Where:
Explanation: The more frequently interest is compounded, the greater the future value will be due to the effect of compounding.
Details: Compounding is a powerful concept in finance that allows investments to grow exponentially over time. It's fundamental to retirement planning, savings strategies, and debt management.
Tips: Enter principal amount in dollars, annual interest rate as percentage, number of compounding periods per year, and investment duration in years. All values must be positive numbers.
Q1: What's the difference between annual and monthly compounding?
A: Monthly compounding calculates interest 12 times per year, resulting in slightly higher returns than annual compounding at the same rate.
Q2: How does compounding frequency affect returns?
A: More frequent compounding leads to higher returns. Daily compounding yields more than monthly, which yields more than annual compounding.
Q3: What's a typical compounding period?
A: Savings accounts often compound daily, CDs monthly or quarterly, and bonds typically compound semiannually.
Q4: Can this calculator handle continuous compounding?
A: No, this calculator uses periodic compounding. Continuous compounding uses a different formula (FV = Pe^(rt)).
Q5: How important is the interest rate in compounding?
A: Extremely important. Small differences in rates can lead to large differences in outcomes over long periods due to compounding effects.
