1. Enter monthly fixed costs
Include overhead that does not materially change with each additional walk for the month modeled.
2. Enter variable cost per walk
Use the incremental labor, transport, supplies, or transaction cost attributable to one completed walk.
3. Enter planned monthly volume
Use completed billable walks rather than inquiries or scheduled visits that are routinely canceled.
4. Review the break-even price
The result is the average revenue required per walk to cover the entered costs at that volume.
5. Add business margin separately
If you need owner profit, tax reserves, or reinvestment, add those goals above the break-even threshold rather than treating break-even as the final selling price.
