Call & lead acquisition costs.
Do the math.
Calculate media cost per acquired customer, compare it with handling costs, and work backward from a target CPA. Use outcomes from the same campaign cohort.
Campaign cost calculator
Use a consistent cohort.
Choose calls or leads delivered within a defined period, then connect those inquiries to the customers they produced. Give the cohort enough time to complete your normal sales cycle. Comparing this week's new leads with last month's completed sales produces a denominator that does not belong to the spend.
Use accepted inquiries as the count in this calculator. If you prefer to calculate against all delivered inquiries, use that definition consistently and label it separately in your own reporting. Do not combine a conversion rate based on contacted leads with a unit cost based on all delivered leads.
The formulas behind the numbers.
| Measure | Calculation | What it tells you |
|---|---|---|
| Net media spend | Gross spend − applied credits | The media cost assigned to the cohort. |
| Inquiry conversion rate | Customers ÷ accepted inquiries | The observed share that became customers. |
| Media CPA | Net media spend ÷ customers | Media cost per acquired customer. |
| CPA including entered handling costs | (Net media spend + handling costs) ÷ customers | A broader measure using only the additional costs you enter. |
| Maximum media cost per accepted inquiry | Target media CPA × inquiry conversion rate | The unit cost consistent with that target if the observed conversion rate holds. |
CPA is not measurable when no customers have been acquired. The calculator reports that condition rather than presenting zero as the acquisition cost. The maximum unit cost is an arithmetic scenario, not a forecast or a price offered by Scale Club.
Worked example: a call or lead campaign.
Suppose a campaign has $5,000 in gross media spend, $250 in applied credits, 250 accepted inquiries, and 25 acquired customers. These are illustrative inputs, not Scale Club results or market benchmarks.
- Net media spend is $4,750.
- Cost per accepted inquiry is $19.
- The accepted-inquiry conversion rate is 10%.
- Media CPA is $190.
- Adding $1,000 in handling costs makes the broader CPA $230.
- A target media CPA of $300 supports a maximum media unit cost of $30 at the same 10% conversion rate.
If the conversion rate falls, the affordable unit cost falls too. If handling expenses rise, the broader CPA increases even if the call or lead price stays unchanged. Evaluate those changes separately instead of assuming that a lower unit price always means a better campaign.
What to include in handling costs.
Choose costs that belong to acquiring the customers in your selected cohort. Depending on your analysis, this may include attributable sales labor, call handling, appointment setting, or relevant software. State what you included. Do not describe the result as fully loaded customer acquisition cost if material costs are left out.
Keep revenue, gross margin, and customer retention separate from acquisition cost. A CPA calculation alone does not establish whether a campaign is profitable. Where outcomes can reverse or take time to mature, use a consistent review point and update your cohort analysis accordingly.
Use the result to choose the next test.
Compare similar products, markets, formats, and sales-cycle maturity. Review answer rates and follow-up before attributing a poor CPA entirely to the source. If your team missed calls or left records unworked, first measure the operational loss.
Share the campaign criteria and the performance stages you can report when discussing a buying program. Scale Club reviews pricing and available formats for each campaign; the calculator does not quote rates or promise outcomes.
