How to calculate appliance repair marketing costs.
Blended lead cost conceals appliance, brand, route, warranty, and parts differences. A refrigeration call in the core route and an unsupported small-appliance request should not be valued equally.
Keep each cost definition separate
| Metric | Formula | Decision |
|---|---|---|
| Cost per inquiry | Spend ÷ tracked calls and forms | Capture efficiency |
| Cost per qualified lead | Spend ÷ repair leads the team can handle | Traffic and intake quality |
| Cost per booked diagnostic | Spend ÷ tracked appointments | Marketing plus office execution |
| Cost per completed repair | Spend ÷ completed attributable repairs | Acquisition economics |
| Return on marketing spend | Tracked job profit ÷ marketing spend | Economic efficiency |
What changes appliance repair marketing cost?
- Appliance categories and urgency mix
- Supported brands, model coverage, and parts availability
- Core versus extended service routes
- Diagnostic fee and customer expectation-setting
- Phone answer, form response, and appointment availability
- Approval, completion, cancellation, and callback rates
- Channel mix, competition, seasonality, and market size
Use the appliance lead-generation system to standardize qualification before judging any source.
Calculate allowable cost from contribution
Repair job profit before marketing = collected revenue − parts − variable technician cost − payment and fulfillment costs − expected callback burden
Allowable cost per completed repair = repair job profit before marketing × acquisition share the business can support
Allowable cost per qualified lead = allowable completed-repair cost × qualified-lead-to-completion rate
If job profit before marketing is $220, the company permits 25% for acquisition, and 45% of qualified leads become completed repairs, the implied ceiling is $55 per completed repair and $24.75 per qualified lead. Replace every assumption with current company data.
Build the budget from capacity
Start with available technician slots by appliance and territory, then estimate qualified leads needed to fill them.
| Input | Why it matters |
|---|---|
| Available diagnostic slots | Sets demand capacity |
| Qualified-to-booked rate | Converts leads into schedule demand |
| Show and completion rates | Adjusts for operational leakage |
| Service contribution | Sets allowable marketing cost |
| Route density | Changes technician productivity |
| Learning allowance | Supports a test large enough to evaluate |
Use the broader local service budget model and pace spend against real availability.
Report ROI by service and source
Join the advertising or organic source to appliance, brand-support status, ZIP, booked diagnostic, diagnosis outcome, approval, completion, collected revenue, parts, and callback. Use the attribution framework for the full source-to-revenue chain.
Marketing ROI = (tracked job profit after acquisition − marketing spend) ÷ marketing spend
Attribution coverage = completed repairs with usable source ÷ comparable completed repairs
A 30-day economics audit
- Define inquiry, qualified repair lead, booking, diagnosis, approval, completion, revenue, and callback.
- Segment historical outcomes by appliance, brand support, territory, and source.
- Calculate actual funnel rates and job profit before marketing.
- Set allowable costs by service group.
- Reallocate budget toward demand the team can handle and available capacity.
- Review results weekly without treating early samples as permanent benchmarks.
