How to use this tool
- Enter the deal details and your assumptions.
- Run the calculation and review cost, risk and sensitivity—not just price.
- Save locally, export JSON or print the report to PDF.
Most important rule: compare the same scope, condition and use period. Otherwise a seemingly cheaper deal may win only because some costs were omitted.
Result limitations
WartoTo does not automatically fetch marketplace prices, assess images or verify seller claims. Result quality depends on input quality. Change assumptions and see whether the decision remains stable.
FAQ
Is the result a market valuation?
No. It uses the inputs you provide. Your benchmark should come from genuinely comparable offers.
Is my data sent to a server?
No. JavaScript performs the calculations in your browser. History is stored locally only when you choose to save it.
Does the verdict replace an inspection or expert?
No. The tool structures the decision and exposes assumptions; it cannot verify condition or listing accuracy.
