What this episode covers
Why free tools (calculators, estimators, graders) attract buyers, not browsersThe difference between a tool that gets traffic and one that generates leadsWhat makes a calculator "warm" — the user has already done the math before they talk to youHow to gate the result (or not) and what actually convertsExamples mentioned
Baremetrics — revenue recovery calculator that leads directly into a trial signupHubSpot — free website grader drives millions of leads; no sales call needed up frontAhrefs — free backlink checker as a top-of-funnel hook into a paid productA simple "how much are you losing to churn" calculator that a solo founder built in a weekendWhy it works at the bottom of the funnel
Visitors who use a calculator are already thinking about the problem in concrete termsThe tool pre-qualifies them — they know the number before you pitch themIt shortens the sales conversation because the buyer arrives educatedOne thing to do this week
Open a spreadsheet and write down the single most painful number your customers track — churn rate, hours wasted, revenue at risk. Then search "[your category] calculator" and see what already exists. If nothing good comes up, that's your opening.
