Leave as 0 to use gross profit per customer.

Results

Results are deterministic scenario outputs, not guarantees.

Enter values and calculate to see the summary, supporting metrics, warnings, and interpretation.

Assumptions

The model assumes ad clicks, leads, customers, and revenue are measured for the same selected period.
Percentages are entered as human-readable values such as 4% and converted to decimals internally.
Required customers, leads, and clicks are rounded up for display while raw calculations remain unrounded.
Outputs are deterministic planning scenarios, not forecasts or guarantees.

Example

If the paid revenue target is $100,000, average order value is $1,000, visitor-to-lead rate is 4%, lead-to-customer rate is 20%, and CPC is $5, the model requires 100 customers, 500 leads, 12,500 clicks, and $62,500 in ad spend.

FAQ

Does this calculator forecast paid media results?

No. It deterministically backsolves from the assumptions you enter and should be used as a planning scenario, not as a prediction or guarantee.

How is maximum affordable CPC calculated?

The calculator multiplies visitor-to-customer conversion rate by either the target CAC you enter or modeled gross profit per customer when no target CAC is supplied.
