Worked example
Use two technician-hours at $35, $30 of product, $20 travel, $10 equipment, a $15 revisit allowance, $100 overhead, 5% contingency and a 30% target margin. The result keeps the planned callback allowance visible instead of hiding it in labor.
| Result | Calculated value |
|---|---|
| True job cost | $257.25 |
| Break-even price | $257.25 |
| Target selling price | $367.50 |
| Planned profit at target price | $110.25 |
These are fictional defaults for explaining the calculation, not a price or outcome claim.
How the calculation works
The revisit allowance is an expected planning cost. This tool does not recommend pesticides, treatment methods or regulatory practices.

Frequently asked questions
What is a revisit allowance?
It is a planning estimate for expected return cost, not a treatment promise or a substitute for your own history.
Does this choose a pesticide or treatment?
No. Product choice, labeling, licensing and treatment requirements remain outside this financial calculator.
Is this a local price benchmark?
No. It uses your cost and margin assumptions and does not claim a prevailing local selling price.
Should labor use person-hours?
Yes. Count each worker’s time so crew size and elapsed time translate into total labor consumed.
How should callbacks be handled?
Use a documented reserve based on your own history and do not count the same expected cost in contingency twice.
Can I use the result as a final quote?
Use it as a planning check, then verify scope, taxes, permits, technical requirements and job-specific risk.
