A roll of film and a selling price are not enough to tell you whether a tinting job works financially. You also spend time preparing, fitting, answering questions, cleaning up and dealing with anything that needs attention. Your business has costs even on days when the diary is quiet. Good pricing starts by making those costs visible.
Worked example only: every dollar amount and time allowance below is hypothetical. This is not a TSO student result, a market-average price, a recommended rate or an earnings forecast. The $350 selling price excludes any sales tax collected; the example does not calculate taxes or personal take-home pay.
Start with one clearly defined $350 job
Assume the scope has been inspected and agreed, with no old-film removal or unusual extra work. In this simplified example, the business receives $350 for the service before the separately listed costs. We will account for the owner's time as a planning cost, even if the owner does not process a wage payment for that exact job.
- Service revenue: $350.
- Film used, including expected cutting waste: $65.
- Consumables: $10.
- Payment-processing allowance: $10.
- Customer-acquisition allowance: $15.
- Total of these job-related costs: $100. Revenue remaining after them: $250.
Stopping after film alone would leave $285. Calling that profit would ignore every other item in the example. Even the $250 remaining after the four job-related costs is not the amount left after all the work of running the business.
Include owner labour and a share of overhead
Assume three hours of total owner time for this job, including its share of preparation, communication and cleanup. At an illustrative $30 per hour planning value, that is $90. The rate is an assumption to make the time visible, not a claim about wages or what every owner should charge.
Next assume $900 of monthly overhead allocated across 20 completed jobs: $45 per job. That hypothetical overhead pool covers workspace, utilities, insurance, software and equipment costs not already counted above. Your real categories and allocation will differ. Do not put the same expense into both the job-cost list and overhead.
- Remaining after job-related costs: $250.
- Less owner labour allowance: $90. Remaining: $160.
- Less allocated overhead: $45. Remaining: $115.
- Less an illustrative expected rework allowance: $15.
- Modelled surplus after these allowances, before taxes: $100, or about 28.6% of the $350 revenue.

What that $100 does—and does not—mean
It is a planning result under the stated assumptions. It is not a bank balance, a tax calculation or guaranteed profit on every job. Owner labour treatment depends on how the business is organised, and an expected rework allowance is not necessarily an expense actually paid that day. Ask your bookkeeper or accountant how the real transactions should appear in your records.
The distinction is still useful: the owner's work deserves recognition separately from the return left for running and risking the business. Otherwise a business can appear profitable simply because the owner has valued all of their own hours at zero. The SBA's break-even guidance explains the role of fixed and variable costs in break-even analysis.
Change an assumption and watch the result
- 1Slower work: an extra hour at the assumed $30 planning value reduces the modelled $100 surplus to $70, with other assumptions unchanged.
- 2A quiet month: if the same $900 overhead is spread over ten jobs instead of twenty, its allocation rises to $90 per job. The modelled surplus becomes $55.
- 3A discount: reducing revenue by $50 would leave $50 if all the cost allowances stay unchanged. Real percentage-based fees may also change, so recompute them rather than copying this shortcut.
- 4A scope change: removal, extra glass or travel can change time and material. Recalculate the actual job instead of hiding the extra work inside the original promise.
Replace the assumptions with your own records
Track material used, whole-job time, payment costs, acquisition costs and rework. Review the overhead allocation when volume changes. Then compare the resulting price with the service you offer and the work customers actually choose. A competitor's headline price may describe a different scope, product or cost structure.
Once you understand the calculation, turn the approved scope into a clear quote. If you are choosing a working model, compare mobile and shop costs without assuming either has zero overhead. The goal is not the biggest sales number. It is work that pays for its real requirements and leaves a result you understand.
