Start with the Growth Economics Calculator if you do not yet know your LTV:CAC ratio or maximum affordable CAC — it is the foundation every other calculator assumes you have. If you already know your unit economics and the question is whether a specific paid media plan pencils out, go straight to the Break-even ROAS Planner or the Paid Media Scenario Forecaster.
If the question is “what does it take to hit a revenue number,” use the Pipeline Backsolver. All five calculators are free, run in your browser, and let you save results to a free Kando account.
