Dog walking Overtime versus Extra Staff
Overtime cost difference = extra hours × overtime rate − extra staff monthly cost
Gather booking history, care schedules and cleaning records. Include walking time, travel, and scheduling. The starting figures are examples. Replace them with your own records.
Formula and worked example
Overtime cost difference = extra hours × overtime rate − extra staff monthly cost
| Input | Example |
|---|---|
| Extra hours needed monthly | 80 |
| Overtime hourly cost | 45 |
| Monthly extra staff cost | 4,000 |
| Calculated result | -400 monthly cost difference |
Choose reliable inputs
Include travel, preparation, cleaning and staffed capacity for each booking. For this dog walking calculation, use booking history, care schedules and cleaning records and a consistent definition of one walk booking.
- Walking time: include the portion belonging to this walk booking or reporting period, and record where the value came from.
- Travel: include the portion belonging to this walk booking or reporting period, and record where the value came from.
- Scheduling: include the portion belonging to this walk booking or reporting period, and record where the value came from.
Use the same currency for every money input. Do not mix weekly costs with monthly revenue, or count the same expense in both an itemised cost and allocated overhead.
Does the cheaper option always have enough capacity?
Check actual available hours, skills, schedules, and service requirements before using a cost-only comparison.
Negative means overtime is cheaper on entered costs only; fatigue, coverage, and hiring costs are excluded.
What if this input changes?
If extra hours needed monthly rises by 10%, this example changes by 360 monthly cost difference. This shows the effect of one change; it does not predict what will happen.
Open the calculator, save your baseline, then change the input supported by the least reliable estimate in your records. Compare both scenarios before committing to a price or capacity promise.
