Behind the Scenes: How It Works
The script uses the following calculation steps:
- APY to Monthly Interest Conversion Monthly Rate=(1+APY100)1/12−1\text{Monthly Rate} = \left(1 + \frac{APY}{100}\right)^{1/12} - 1Monthly Rate=(1+100APY)1/12−1
- Monthly Compounding Formula
For each month: Balance=(Previous Balance×(1+Monthly Rate))+Monthly Contribution\text{Balance} = (\text{Previous Balance} \times (1 + \text{Monthly Rate})) + \text{Monthly Contribution}Balance=(Previous Balance×(1+Monthly Rate))+Monthly Contribution - Result Formatting
Final numbers are neatly formatted with commas and two decimal places.
