What annual return rate should I use?
The S&P 500 has historically returned about 10% annually (7% after inflation). For diversified portfolios, 6–8% is a common conservative estimate. For bonds or conservative portfolios, 3–5% is more realistic. This calculator does not predict future performance — use conservative estimates for planning.
How does compounding frequency affect returns?
More frequent compounding (monthly vs. annually) results in slightly higher returns because interest is calculated on a larger base more often. The difference is modest but grows over long time horizons.
Why does time in the market matter so much?
Compound growth is exponential — the longer your money is invested, the more powerful the effect. Starting 10 years earlier can easily double or triple your final balance, even with the same monthly contribution amount.
