Worked examples
Worked examples for practical decisions
Worked Toolkit Shelf examples that show the scenario, inputs, formula, result, interpretation, and next tool to use.
Start here
Use examples when the formula is clearer with numbers.
These pages are scenario-first. Each one shows realistic inputs, the formula, the result, and the related calculator to rerun with your own assumptions.
Use them when a single result is not enough context. The example explains why the input values were chosen, which calculator was used, what the answer means, and what would need to change before the result applies to a real household, business, creator, or planning decision.
A worked example that estimates the monthly cost of a manual review queue, then checks what happens if automation covers part of the work.

They make the assumptions visible.
A calculator gives the answer for one input set. A worked example shows how the input set was chosen, where the result comes from, and what to inspect before trusting it.
Each example is reviewed as a companion to a live tool, not as a standalone article stuffed around a keyword. If the formula, units, or assumptions do not fit the scenario anymore, the example should be corrected alongside the calculator it points to.
Review standard
Examples must make the calculation easier to audit.
A good Toolkit Shelf example should answer four questions: what is being estimated, which inputs are known, which method is being used, and what warning would change the interpretation. Examples that only repeat the calculator title do not belong here.
