Frequently Asked Questions
How is investment return calculated?
We calculate compound returns: Future Value = P(1+r)^n + PMT[((1+r)^n-1)/r], where P=initial investment, r=annual return, n=years, PMT=monthly contributions. This shows both growth of initial capital and regular contributions.
What's a good annual return?
Historical averages: S&P 500 ~10%, bonds ~5%, real estate ~8-12%, savings accounts ~0.5-4%. Past performance doesn't guarantee future results. Diversified portfolios typically target 6-8% after inflation.
How do I compare investment options?
Our calculator lets you compare: different return rates, time periods, contribution amounts, and fees. Small differences in fees (0.5% vs 1%) can cost tens of thousands over 30 years. Always factor in taxes and inflation.
