The Compound Interest Calculator moved beyond a single lump-sum principal to something more practical.
- Monthly deposits: Enter a monthly deposit separately from the principal, and the calculator factors in the compounding effect of adding the same amount every month.
- 15.4% interest tax: Flip one checkbox to compare the pre-tax and after-tax amounts instantly.
- Currency switcher: Change the displayed currency to USD, EUR, JPY, or type in any custom unit.
- Growth chart: See how the balance builds up over the term in a single chart.
- Copy and shortcuts: Copy the results as text, or move faster with ⌘+⇧+C and Esc.
