How to Use This Calculator
- Enter the Principal Amount — the initial lump sum you are investing or depositing.
- Set the Annual Interest Rate as a percentage (e.g., 5 for 5%).
- Enter the Number of Years to see how the balance grows over time with daily compounding.
- The calculator uses 365 compounding periods per year: A = P × (1 + r/365)^(365×t).
- Effective Annual Rate shows the true yearly yield after daily compounding — always slightly higher than the nominal rate.
- The timeline chart plots year-by-year balance so you can visualize the exponential growth curve.
