About
Built for the gap between the estimate and the outcome.
TradeUp Tools is a free collection of practical planning calculators created and maintained by Walter Thornton for contractors and home-service operators.
What we make
The tools follow the operating sequence of a job: understand true cost, recover overhead, price the work, measure production, and compare the finished result with the estimate.
What we do differently
The calculation is available before any signup or pitch. Formulas and limitations are visible. Business inputs stay in the browser. Where a partner or owned service is relevant, it is presented as an optional next step after the complete result.
Working status
TradeUp Tools is part of Walter Thornton's broader digital-asset portfolio. The working name and free-hosting address may change after real usage data supports a permanent domain.
