1. Define what the service includes
List the vehicle type, service scope, expected condition, and exclusions. A quick maintenance visit and a heavily soiled interior need different time assumptions. Record add-ons separately so the quote explains changes in scope.
2. Put a cost on the working time
Estimate hands-on hours and a labor cost per hour. Include your own working time even if you are the only person doing the job. Owner labor compensation and business profit are different amounts; do not count the same payment twice.
3. Add the costs around the work
Estimate consumed supplies, job-related travel costs, and an allocation of overhead such as insurance or software. Use actual records when available. Spread overhead consistently across a realistic number of jobs; update the assumption when your workload changes.
4. Choose a pricing method
In this simplified example, all four cost categories are included before applying the pricing percentage. The toolkit separately distinguishes direct-cost gross margin and profit after overhead.
| Fictional input | Calculation | Amount |
|---|---|---|
| Labor | 2 hours × $30 | $60 |
| Materials | Per job | $12 |
| Travel | Per job | $8 |
| Allocated overhead | Per job | $10 |
| All entered costs | Sum | $90 |
$90 ÷ (1 − 0.40) = $150 before tax.
The $60 difference is the surplus after these entered costs. Additional expenses, discounts, or a longer job reduce it. These numbers are teaching examples, not typical detailing rates.
5. Check the price against real work
Compare service scope with relevant local alternatives and customer feedback. After each job, record actual time and costs. Investigate the gap between the estimate and the outcome before changing every price.
