Ad funnel calculator

CPM, CTR, CVR, CAC and ROAS aren't five separate numbers - they're one equation. Pick the metric to solve for, set a benchmark and a target, and watch a small lift on one ripple through the rest.

Pick the metric to calculate. Set the rest. It is all one equation - move CTR or CVR and watch CAC and ROAS move with it.

Same spend, better funnel. Moving your target inputs takes CAC from $60 to $16 and ROAS from 1.33x to 5.04x. A small lift on CTR and CVR compounds through the whole funnel - that is the leverage most accounts leave on the table.

CAC = (10 × CPM) ÷ (CTR% × CVR%)  ·  ROAS = AOV ÷ CAC

We find the metric holding your funnel back - and the fastest way to move it.
