FAQ
- How does compound interest work?
- Compound interest earns returns on both your original principal and the returns already accumulated, so growth accelerates over time — especially with regular contributions.
- What return rate should I use?
- Use a realistic long-term estimate. Historically broad stock-market index funds have averaged roughly 6–8% per year after inflation, but past performance does not guarantee future results.
- Does this account for inflation or tax?
- The calculator shows nominal growth before tax and inflation. For real purchasing power, subtract your expected inflation rate from the return you enter.
