Frequently Asked Questions
What is the difference between simple and compound interest?
Simple interest is calculated only on the principal. Compound interest is calculated on the principal PLUS accumulated interest, so your balance grows faster over time — this is the "interest on interest" effect.
How does compounding frequency affect my returns?
More frequent compounding means slightly higher returns. Daily compounding earns a bit more than monthly, which earns more than annual. The difference grows with larger balances and longer time horizons.
Can I include regular monthly contributions?
Yes — enter a monthly contribution amount in the Additional Contribution field to see how regular deposits accelerate growth through compound interest.
What is the Rule of 72 and how does it relate to this calculator?
The Rule of 72 estimates how long it takes to double your money: divide 72 by your annual interest rate. At 8%, money doubles in about 9 years. Verify this by running the calculator with your rate.
Is this calculator accurate for savings accounts or investments?
