What is a realistic mutual fund return?

Broad US stock index funds have historically returned 7%–10% annually over long periods (before inflation). Bond funds typically return 3%–5%. A balanced fund might average 5%–7%. Use a conservative rate for planning.

Does this account for expense ratios?

No. Mutual fund expense ratios reduce your effective return. Subtract the fund's expense ratio from your expected return. A fund with 1% expenses and 8% gross return effectively compounds at ~7%.

What about taxes on gains?

Gains in taxable accounts are subject to capital gains tax. Gains inside a Roth IRA or 401(k) grow tax-deferred or tax-free. This calculator shows pre-tax figures.

How does starting early affect results?

Compounding rewards time dramatically. Investing $500/month for 30 years at 8% produces about $745,000 vs. $344,000 for 20 years — 10 extra years nearly doubles the result while only adding $60,000 more in contributions.

Should I use lump sum or monthly contributions?

Both strategies have merit. Lump-sum investing historically outperforms dollar-cost averaging about two-thirds of the time because money is invested sooner. Monthly contributions reduce timing risk and build the habit of regular saving.
