Understanding This Calculator
Compounding frequency matters — but not as much as you think. See the exact gap between daily, monthly, quarterly, and annual compounding for your specific numbers.
Core Formula
A_daily = P(1 + r/365)^(365t) vs A_monthly = P(1 + r/12)^(12t)
How much more does daily compounding give?
For typical savings rates (3-5%), daily compounding adds a tiny fraction of a percent per year compared to monthly compounding.
Do all banks use daily compounding?
Most high-yield savings accounts now use daily compounding, but CDs may use monthly or quarterly. Always check the fine print.
