Compound Interest Calculator FAQ

What does “compounding frequency” mean?
Compounding frequency is how often interest is added to your balance (monthly, quarterly, or yearly). More frequent compounding usually results in a slightly higher final balance.
Should I include expected inflation in the rate?
This calculator works with a nominal annual interest rate. If you want to account for inflation, you can compare different rate scenarios (for example, expected return minus estimated inflation).
Is this a guarantee of future returns?
No. The results are hypothetical examples based on the rate you enter. Real returns vary depending on the savings or investment product and market performance.
