Frequently Asked Questions
- How much will $2,000 grow in 20 years?
- At a typical 8% annual return (roughly the long-term stock market average), $2,000 grows to about $9,854 in 20 years with no additional contributions, thanks to compound interest.
- What return rate should I assume?
- The S&P 500 has historically returned about 10% per year before inflation (roughly 7% after inflation). For conservative planning, many advisors suggest 6%–8% for a diversified stock portfolio.
- Does adding monthly contributions change the result a lot?
- Yes, dramatically. Regular contributions compound alongside your initial amount. Use the calculator below to see how adding even $100–$500/month changes your 20-year outcome.
- Is compound interest the same as simple interest?
- No. Simple interest is calculated only on the original principal. Compound interest is calculated on the principal plus all previously earned interest, so growth accelerates over time instead of staying flat.
