Collect comparable records and keep classification outside the result
Use gross, pre-tax amounts on both sides. The employee scenario needs pay, entered benefits, committed time and direct work costs. The contractor scenario needs a proposed rate, billable capacity, recurring non-billable time, entered benefits and business costs.
A contract label or calculator result does not establish worker status across markets. Check the actual relationship and applicable local rules with official or professional guidance.
- Employee base pay, variable pay and benefits
- Employee paid, unpaid and commute time
- Contractor billable hours and realistic working weeks
- Recurring contractor admin, sales and delivery-support hours
- Contractor benefits and annual business costs
Do not use billable hours as the whole time denominator
Contractor revenue is hourly rate multiplied by annual billable hours. Committed time also includes recurring non-billable work such as administration and business development. The fixture has 1,380 billable hours but 1,748 committed hours, so revenue and hourly-value calculations use different time concepts.
Worked example: one proposed rate and two parity rates
| Measure | Employee | Contractor |
|---|---|---|
| Core pay/rate | 80,000 base + 4,000 variable | 65 per billable hour |
| Entered benefits | 10,000 | 0 |
| Direct/business costs | 3,000 | 12,000 |
| Annual billable hours | — | 1,380 |
| Annual committed hours | Employee schedule basis | 1,748 |
| Annual value difference | Baseline | -13,300 |
| Hourly value difference | Baseline | +1.61/hour |
| Annual-value parity rate | — | 74.64/billable hour |
| Committed-time parity rate | — | 62.96/billable hour |
Use the two thresholds for different questions
The 74.64 rate matches the employee’s 91,000 net annual work value after contractor costs and benefits. The 62.96 rate matches the employee’s value per committed hour using contractor committed time. They differ because matching a year’s value is not the same as matching value for each hour committed.
- Lower billable hours or working weeks
- Higher recurring non-billable hours
- Higher business or insurance costs entered by the user
- Payment gaps and collection risk kept outside the deterministic result
- Local classification, tax and statutory obligations checked separately
