Guide
How the compound interest calculator works
The calculator applies interest repeatedly within each year, which produces a more realistic long-term estimate than simple interest alone.
- Use it to compare scenarios before you commit to a financial decision.
- Check the assumptions carefully, especially rates, time periods, and taxes.
- Treat the result as a planning estimate rather than a formal quote.
