Pro Tips

  • The S&P 500 has returned ~10% annually before inflation (~7% after) over the long term, but any single year can be -30% or +30%
  • Fees matter enormously: a 2% annual fee vs 0.1% on $100,000 invested for 30 years at 7% costs you $190,000 in lost growth
  • Dollar-cost averaging (investing the same amount regularly) reduces the risk of buying at market peaks

Common Mistakes to Avoid

  • Chasing past performance: last year's top fund is rarely this year's top fund. Past returns don't predict future results
  • Panic-selling during market drops: investors who stayed invested through the 2008 crash recovered all losses within 3 years. Those who sold at the bottom locked in permanent losses
  • Ignoring taxes: capital gains taxes can take 15-20% of your investment profits. Use tax-advantaged accounts (IRA, 401k) when possible

Frequently Asked Questions

What's a good annual return on investment?

The historical average for the S&P 500 is ~10% nominal (7% after inflation). A 'good' return depends on your risk tolerance. Conservative portfolios (bonds) may earn 3-5%. Aggressive portfolios (stocks) may earn 8-12% long-term. Use our investment return calculator to model different scenarios.

How do I calculate my investment return?

ROI = (Current Value - Initial Investment) / Initial Investment × 100. Example: $10,000 grows to $13,000 = 30% total return. For annualized return: use CAGR = (Ending Value / Starting Value)^(1/years) - 1. Our calculator does both instantly.

What's the difference between nominal and real return?

Nominal return is the raw percentage gain. Real return adjusts for inflation. Example: 8% nominal return with 3% inflation = ~5% real return. Always plan retirement using real (inflation-adjusted) returns — your future expenses will be in future dollars.
