Money, Straight The 20-Year Calculator
Your numbers never leave this screen

See what fees and time do to your money — in dollars, not percentages.

Split your money the honest way — some reachable for emergencies, most invested for years — then watch four real approaches race over 20 years. The gap between the cheapest and the costliest is the fee, shown as the dollars it quietly takes. Move anything. It all computes right here on your device.

Cheapest path ends at $134,684 DIY index fund · $35,000 invested for 20 yrs
Costliest shown loses $32,571 to fees vs the cheapest — that's 93% of what you invested
Your reachable cash — $0 at 4.0% — grows to $0 over the same 20 years, and it's never at risk. Both jobs, side by side.

The 20-year race

Every line starts at the same invested amount and earns the same market return. They only diverge because of fees. The shaded wedge is the money the fees take.

The bad years, in real dollars

Investing means real down years. Here's what history's worst did to your invested amount — and the honest other half: markets recovered. The green bar is 2020, which fell about 34% in the spring and still finished the year up.

What “just 1%” really is

A 1% fee sounds tiny. But it's 1% of everything you own, taken from a return of only a few percent — so it eats a big slice of each year's growth.

A 1.00% fee on a 7.0% return is 14% of that year's growth — handed over every year, up markets and down.

Your safe bucket, growing too

The reachable cash isn't idle. At the savings rate it compounds steadily — no drama, no risk, always there.

Read this — it's not fine print

This is not financial advice. Nothing here is personalized to you — it's a tool to see the math for yourself, with real, current numbers. It doesn't know your job, your debts, your family, or your plans. It can't tell you what to do.

You make the call. The market's future is unknown; every projection here is an assumption you set, compounded forward — not a promise. Past down years are real history, not a forecast. Rates and fees shown reflect mid-2026 and will change.
