Common Questions Answered

Quick help
Q1 What is the difference between APR and APY?
APR is the simple interest rate over a year, while APY accounts for compound interest, yielding a higher effective annual rate.
Q2 How does compounding frequency affect APY?
More frequent compounding (e.g., daily vs. annually) increases the effective yield and results in higher overall earnings on the same principal.
Q3 Can I input negative interest rates?
No, the calculator limits inputs to positive numerical values to reflect standard financial deposit rates.
Q4 Does the calculator support custom compounding frequencies?
Yes, you can choose daily, weekly, bi-weekly, monthly, quarterly, semi-annual, or annual compounding presets.
Q5 Are my financial variables saved on a database?
No, all interest math is calculated client-side in the browser sandbox. None of your data is sent to external servers.
