FUTURE AFFORDABILITY CALCULATOR

You earn well. Is the future you want moving faster than your assets?

Price one goal, add what's working toward it, and see the annual rate your future requires — and whether you're on pace.

STEP 1 — THE FUTURE YOU WANT

What are you trying to afford?

Want to understand the output before using your numbers? Open a clearly labeled example.

Optional. Use a zip or metro when location drives the cost.

This costs about
today. I want it in
years.

STEP 2 — YOUR CURRENT TRAJECTORY

What do you have working toward it?

Ready to see your gap? Add assets and monthly contributions. Asset and contribution amounts stay in this browser unless you choose to save a result.

Include the assets you would realistically use to reach this goal. Round numbers are fine.

Calculated in your browser — we never see this number.

Optional. This helps the Simulator estimate how your trajectory changes if you keep adding.

Assumptions behind this estimate
  • Cash & savings: assumed 4.0% — illustrative cash/HYSA assumption (FDIC national savings rate: 0.38%, Apr 2026)
  • Stocks & index funds: assumed 13.1% — S&P 500 total return over the latest source window
  • Real estate: assumed 6.5% — Case-Shiller over the latest source window
  • Other: assumed 6.0% — configurable blended default

Add total assets to calculate your result.

Enter total assets to calculate Aspire Rate and Aspire Gap at these assumptions.

The Simulator opens after the calculator has a real result to carry forward.

WHY THE GAP EXISTS

Your future does not move at one inflation rate.

Markets, homes, healthcare, tuition, and everyday life compound at different rates. Aspire uses the mix behind your goal and your assets to make that difference visible.

These annualized source rates are context, not your result. Your result depends on the future you choose and the assumptions shown with it.

What you earn adds. What you want compounds. The gap is the whole story — recalculate yours or read The Escalator Problem.

THE RECEIPT

We publish our work.

The Aspire Index is our dated, source-stamped record of what a starter home costs in hours of ordinary work — every number traceable to a public source, every print shipped with its data and method. It exists so you can check us, not so you have to learn it.
