Frequently Asked Questions

1 What is the difference between APR and APY?
APR (Annual Percentage Rate) is the simple interest rate without compounding. APY (Annual Percentage Yield) includes the effect of compounding interest. APY will always be higher than APR when compounding occurs more than once per year.
2 How does compounding frequency affect APY?
The more frequently interest compounds, the higher the APY. Daily compounding yields the highest APY, followed by monthly, quarterly, and annual. For example, a 5% APR compounds to 5.12% APY with daily compounding, but only 5.00% with annual compounding.
3 Can I use this calculator for cryptocurrency or other investments?
Absolutely! The APY formula works for any investment that compounds interest, including savings accounts, CDs, bonds, and crypto staking platforms. Just enter the APR and compounding frequency specific to your investment.
4 Does the calculator account for inflation or taxes?
The APY calculator provides the nominal return before taxes and inflation. For real returns, you would need to account for your tax rate and the inflation rate separately. We're working on adding these features in a future update.
5 Is my financial data stored or transmitted anywhere?
No. All calculations run entirely in your browser. Your financial data is never sent to our servers, stored in cookies, or shared with any third parties. The tool uses pure JavaScript to compute results locally on your device, ensuring complete privacy.
