Acquisition Costs
Understanding how much it costs you to attract a prospect at each stage of the sales process.
Overview
| KPI | What It Measures | How to Read It |
|---|---|---|
| CPL | Cost per Lead | Ad spend / number of leads |
| CPAPP | Cost per Application | Ad spend / applications received |
| CPB | Cost per Booking | Ad spend / appointments booked |
| CPA | Cost per Acquisition | Ad spend / sales closed |
General Principle
The lower the cost, the more efficient your acquisition. But be careful: a very low CPL with a very high CPA may indicate a lead quality problem.
CPL: Cost per Lead
The average amount spent on advertising to obtain a lead (a prospect who submitted their contact information).
Example: $5,000 in ads generating 250 leads = CPL of $20
CPL helps you evaluate whether your ads are attracting people efficiently. A rising CPL may mean:
- Your target audience is saturated
- Your ads need refreshing
- Competition is stronger right now
TIP
Compare your CPL week-over-week rather than day-over-day. Daily variations are normal.
CPAPP: Cost per Application
The average amount spent to obtain a completed application (a detailed form, qualification questionnaire, etc.).
Example: $5,000 in ads generating 80 applications = CPAPP of $62.50
CPAPP measures the efficiency of your qualification process. A high CPAPP relative to CPL indicates many leads are dropping off before completing the application.
CPB: Cost per Booking
The average amount spent to obtain a booked appointment. This is often the most important KPI for evaluating your pipeline.
Example: $5,000 in ads generating 30 bookings = CPB of $166.67
Why CPB Is So Important
A booking is a qualified prospect who took the time to schedule a call. It's the step right before the sale. If your CPB is stable and your close rate is good, you can reliably predict your revenue.
CPA: Cost per Acquisition
The average amount spent to generate a sale. This is the ultimate efficiency KPI: how much it costs you to get a new client.
Example: $5,000 in ads generating 8 sales = CPA of $625
CPA must always be evaluated relative to your average ticket. A CPA of $625 is excellent if your product sells for $3,000, but problematic if it sells for $500.
Complete Example
Here's a scenario showing all 4 costs together:
| Stage | Quantity | Cost |
|---|---|---|
| Ad Budget | $8,000 | |
| Leads | 400 | CPL = $20 |
| Applications | 120 | CPAPP = $67 |
| Bookings | 45 | CPB = $178 |
| Sales | 12 | CPA = $667 |
Reading: it costs $20 to attract a lead, $67 for them to fill out an application, $178 for them to book an appointment, and $667 to close a sale. If the average ticket is $2,500, the ROI is 3.75x: very good.
Why Do Some KPIs Not Appear?
Acquisition costs only display when there is data at the corresponding stage.
- No CPL displayed? No leads recorded in the selected period.
- No CPA displayed? No sales closed in the period.
This is normal behavior, not an error. If your campaign just started, the first KPIs to appear will be CPL and CPAPP. CPB and CPA will follow once the first appointments and sales are recorded.
TIP
When a cost isn't displayed, it means there isn't enough data to calculate it meaningfully. That's better than displaying a misleading number.
