A 1,200 average annual tax refund invested at 7% for 30 years grows to roughly 113,000. Over a full career, tax refunds are real wealth-building opportunities most people spend rather than invest. Setting up an automatic transfer from the refund-receiving account to an investment account is the simplest fix.
Why tax refunds are high-leverage
They're 'unexpected' money — not part of your monthly budget — so investing them doesn't cut into lifestyle. That makes them psychologically easier to save than regular income. Automating the save-refund habit removes the spending temptation.
Run it with sensible defaults
Using average annual refund of 1,200, annual return of 7%, years remaining of 30 years, the calculation works out to 113,352.94. Nudge the inputs toward your own situation and the output recalculates instantly. The defaults are meant as a starting point, not a recommendation.
The levers in this calculation
The inputs — Average Annual Refund, Annual Return, and Years Remaining — do not pull with equal force. The rate and the time horizon usually dominate — compounding means a small change in either reshapes the final figure more than a similar shift in contribution size. Test this by doubling one input at a time.
How the math works
Standard future value of annual annuity. Assumes refund is invested once per year when received, at the annual return rate. The working is transparent — you can verify every step yourself in the formula section below. No black box, no opaque "proprietary model".
Using this well
Treat the output as one point on a wider map. Run it three times — a pessimistic case, a central case, and a stretch case — and plan against the pessimistic one. That habit alone separates people who stick with an investment plan from those who bail at the first wobble.
What this doesn't capture
Steady-rate math ignores real-world volatility. Actual returns are lumpy; sequence-of-returns risk matters most in drawdown; fees and taxes drag on compound growth; and behaviour changes in drawdowns can reduce outcomes below the projection. Treat the number as one scenario, not a forecast.
