What it does
A calculator design that gives visitors a real answer they can defend to their boss, and still brings in good leads. Many calculators are bait: made-up multipliers and the result hidden behind a form. This one earns trust instead. The skill first decides if a calculator is the right tool for your audience. Then it designs the inputs, keeps the questions few, and shows the method so the result can be questioned. It sets out a fair trade. People get a useful result first, and a deeper report can sit behind an email address. It cites sources for any benchmark numbers. It also suggests how to judge lead quality from the answers people give.
