Does the calculator tell me whether to hire or use overtime?

No. It reports modeled cost and productive capacity without making a staffing recommendation.

How does training ramp affect a hire?

During the entered ramp weeks, productive capacity rises from the scenario's starting productivity toward the common utilization assumption.

How is a contractor minimum commitment used?

Weekly billed hours are the greater of entered billable hours and the minimum commitment before the fee is applied.

What does unfilled demand mean?

It is modeled required productive hours minus modeled productive capacity, never below zero. It is not a service-level or legal conclusion.

Does the contractor result validate worker classification?

No. The contractor card is a financial scenario only and makes no classification finding.

Four-way capacity and cost model

Overtime vs Hiring Calculator

Set one productive-hours demand, then compare continue-overtime, part-time, full-time, and contractor modeled scenarios on cost, usable capacity, ramp time, unfilled demand, and break-even timing.

Model overtime, two hires, and a contractor

Use utilization to convert scheduled or billable time into productive capacity. Hiring scenarios ramp toward that utilization; all four results remain comparisons, not recommendations.

Currency Required additional productive hours / week Duration (weeks) Utilization (%) Training ramp (weeks)

Continue overtime modeled scenario

Existing employee count Base hourly wage Overtime multiplier OT payroll burden (%) Differential per OT hour Maximum modeled OT hours / employeeA capacity assumption only; it is not described as a legal limit.

Hire part-time employee modeled scenario

Hourly wage Scheduled hours / week Benefits / week Payroll burden (%) Recruiting cost Onboarding / training cost Equipment cost Recurring overhead / week End-of-project cost Starting ramp productivity (%)

Hire full-time employee modeled scenario

Contractor modeled scenario

Contractor hourly rate Billable hours / week Agency / platform fee (%) Minimum weekly commitment Setup cost

Cost comparison only: inputs are not saved. The modeled scenarios do not assess classification, morale, fatigue, safety, quality, turnover, legal risk, or whether any staffing choice should be made.

Four cost structures answering one demand question

The overtime scenario is primarily variable: modeled hours multiplied by the overtime wage, differential, and burden. Employee-hire scenarios add recruiting, onboarding, equipment, benefits, and overhead to recurring wages. The contractor scenario combines rate, agency fee, minimum commitment, and setup cost.

The overtime vs hiring calculator applies the same duration and utilization assumption across the comparison. That shared baseline makes the cost structure visible without pretending that the four forms of labor are operationally equivalent.

Productive hours are not the same as scheduled hours

Utilization converts scheduled, overtime, or billable hours into modeled productive capacity. If twenty productive hours are required at 80% utilization, a scenario needs 25 scheduled hours to fill that demand. A zero utilization input produces zero productive hours rather than a divide-by-zero result.

Part-time and full-time productive capacity ramps from the entered starting productivity toward the common utilization percentage. The capacity table retains each week's value, while total unfilled demand compares accumulated productive hours with accumulated required hours.

Cost, capacity, and break-even model

A break-even week is shown only when the modeled cumulative cost crosses within the selected duration. It compares financial inputs; it is not a point at which hiring becomes legally, operationally, or ethically required.

The sensitivity table changes required demand to 80%, 100%, and 120% while preserving scenario cost assumptions. It exposes capacity risk even when the cost bars do not change.

productiveHours = scheduledHours × utilization × rampFactor
hireTotal = fixedStartCosts + weeklyWageAndBurden × duration
contractorWeekly = max(billableHours, minimumCommitment) × rate × (1 + fee)
unfilledDemand = max(totalDemand - productiveCapacity, 0)
breakEvenWeek = first week scenario cumulative cost ≤ overtime cumulative cost

Worked project comparison

Imagine a 26-week project requiring 24 additional productive hours each week at 85% utilization. Four existing employees with a ten-hour maximum modeled overtime capacity provide at most 34 productive hours, but their cost remains tied to the hours needed for the demand. A part-time schedule may carry lower fixed costs but lose capacity during ramp weeks.

A contractor billed for 24 hours with a 20-hour minimum is charged for 24; if billable hours fall to 12, the minimum raises billed time to 20. The comparison reports that commitment explicitly rather than hiding it inside an effective rate.

Factors no bar chart can resolve

This model does not score morale, fatigue, turnover, safety, quality, knowledge retention, recruiting lead time, contractor classification, employee-status rules, or legal exposure. It also does not assume the least expensive total is the best scenario.

Use the output to inspect assumptions and ask better operational questions. Staffing, classification, wage, benefit, tax, accounting, and human-resources decisions require separate current evidence and qualified review.
