Tips
- Even small rate differences compound hugely over long periods — compare carefully.
- The year-by-year table shows when growth really speeds up, usually in later years.
- This tool ignores tax and inflation, so treat results as the nominal outcome.
- Try different compounding frequencies to see how they change the total.
