Estimate tools

What-if calculators for essays and teaching. Every output is an estimate under editable assumptions — not a forecast. Formulas and default provenance are documented in methodology.

Estimates only. These tools are illustrative what-if calculators for teaching and writing — not forecasts, quotes, fab plans, or legal/compliance advice. Defaults are curated teaching values; replace them with your own inputs.

How to use these tools

  1. 1Pick a calculator below for the story you want to explore.
  2. 2On each tool page, edit Assumptions on the left. Amber badges are teaching estimates; they flip to Your input when you change a value.
  3. 3Read Estimated results on the right (~ means estimate). Open Methodology for formulas and default provenance.
