Build the employee baseline and contractor capacity separately
The employee fixture produces 91,000 of net annual work value after direct costs. Contractor capacity is 30 billable plus eight non-billable hours a week for 46 weeks. Do not apply a fixed uplift to salary or assume every working hour can be billed.
- Employee base pay, variable pay and entered benefits
- Employee direct work costs and all committed time
- Contractor billable hours per week and working weeks per year
- Recurring non-billable hours for admin, sales and other work
- Contractor benefits and annual business costs
Understand why the two parity formulas answer different questions
Annual-value parity solves for the rate that makes contractor annual value equal 91,000 after entered contractor benefits and 12,000 of business costs. Committed-time parity first matches the employee’s value per committed hour, then funds that value across the contractor’s committed hours.
Both formulas divide the required contractor revenue by 1,380 billable hours. The committed-time formula also accounts for 1,748 total contractor hours, including 368 non-billable hours.
Worked rate bridge
| Rate bridge row | Result |
|---|---|
| Employee net annual work value | 91,000 |
| Contractor billable capacity | 30 × 46 = 1,380 hours |
| Contractor committed time | (30 + 8) × 46 = 1,748 hours |
| Annual contractor business costs | 12,000 |
| Annual-value parity rate | 74.64/billable hour |
| Committed-time parity rate | 62.96/billable hour |
| Proposed rate for context | 65/billable hour |
| Annual difference at proposed rate | -13,300/year |
Stress-test utilization instead of relying on an uplift rule
These are scenario directions, not utilization benchmarks. Demand, payment delay, project gaps, insurance needs and compliance costs must be assessed and entered where relevant. Check local tax and classification obligations separately, and use Employee vs Contractor for a complete proposed arrangement.
| Assumption change | Expected threshold effect |
|---|---|
| Fewer billable hours | Both parity rates rise |
| More non-billable hours | Committed-time parity rises |
| Higher business costs | Both parity rates rise |
| Higher contractor benefits | Both parity rates fall |

Worked example: Contractor Rate Equivalent Calculator
The calculator normalizes the inputs above, applies Committed-time parity rate, and returns the outputs below. The displayed result is therefore reproducible in the linked calculator.
| Measure | Result | Interpretation |
|---|---|---|
| Committed-time parity rate | 62.96 currency units/billable hour | Rate needed to match employee effective value per committed hour. |
| Annual-value parity rate | 74.64 currency units/billable hour | Rate needed to match employee net annual value. |
| Difference at proposed rate | -13,300 currency units/year | Contractor net annual value minus employee value at the proposed rate. |
| Employee net annual work value | 91,000 currency units/year | Employee compensation less entered direct work costs. |
