Formula
Paid revenue target
paidRevenueTarget = max(0, revenueTarget - currentOrganicOrExistingRevenue)
Customers required
customersRequired = paidRevenueTarget / (averageOrderValue + repeatRevenuePerCustomer)
Traffic required
clicksRequired = (customersRequired / leadToCustomerRate) / visitorToLeadRate
Estimated ad spend
estimatedAdSpend = clicksRequired × averageCpc
Maximum affordable CPC
maximumAffordableCpc = (targetCAC or grossProfitPerAcquiredCustomer) × visitorToCustomerRate
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.
Worked example
Example: revenue target backsolve
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.
Why is existing non-paid revenue subtracted from the target?
Only the remaining revenue gap needs to be modeled as paid acquisition demand, so existing organic or retained revenue reduces the paid target.
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.
