Stuff-to-Wealth Calculator
See what the things you no longer use could become if you sold them and invested the money instead. Uses hypothetical return assumptions only — not forecasts, funds, or brokerage offers.
One Item
I sold something today. What could that money become if I invested it?
Investment returns are uncertain. This is a mathematical scenario, not a forecast.
Advanced assumptions
Spend it or invest it?
Spending gives you the sale amount of value today. Investing changes what that same money could potentially become over time.
Compare return assumptions
These are mathematical scenarios, not forecasts. Higher returns are not necessarily realistic or preferable.
| Scenario | Return | Final value | Investment growth |

Investment value over time
Chart updates as you change inputs.
How much money is hiding in your home?
Estimate resale value by category, then see what the total could become if invested.
You estimate that you could sell $0 worth of unused items.
How we calculate this
This calculator models hypothetical compound growth. It does not include taxes, account fees (unless you later enable fee support in the model), or guaranteed returns.
- Lump sum: future value = amount × (1 + return)^years.
- Recurring contributions: end-of-period contributions (ordinary annuity). Monthly mode compounds monthly; yearly mode compounds annually.
- Stopping early: contributions grow until the stop age, then the accumulated balance compounds with no new contributions until the final age.
- Inflation toggle: when enabled, today's purchasing power ≈ future value ÷ (1 + inflation)^years.
- All figures are educational scenarios. Actual investment results will differ.
FAQ
Is 7% a guaranteed return?
No. Seven percent is only a common long-term modeling assumption. Returns can be lower, higher, or negative for long periods.
Does this include taxes or fees?
No. Version 1 excludes taxes and default investment fees so the math stays transparent.
Why might monthly results differ from the guide examples?
Some guide examples use annual compounding for simplicity. This calculator uses monthly compounding for monthly contributions, which is more precise.
Is this investment advice?
No. It is an educational planning tool for understanding compound growth scenarios.
