Frequently asked questions

Are these returns guaranteed?

No β€” projections assume your inputs hold steady. Real markets fluctuate; treat results as planning estimates.

What's a reasonable long-term return?

Diversified U.S. stock portfolios have averaged 7–10% before inflation over the long run.

Should I include inflation?

Yes if you care about purchasing power. Use a real return = nominal return βˆ’ inflation rate.

Do taxes affect this?

Inside tax-advantaged accounts (401k, IRA, HSA) growth is tax-deferred or tax-free. Taxable accounts pay annual tax on distributions and on gains when sold.

Does dollar-cost averaging help?

It smooths timing risk and is a behavioral win even if a lump-sum invested earlier has higher expected return.
