How to use this calculator

  1. Set currency, number of temps, and assignment duration.
  2. Enter regular and overtime hours per week per temp.
  3. Add hourly rate, overtime multiplier, and employer tax rate.
  4. Include benefits per hour, agency markup, and per-temp fees.
  5. Adjust overhead, contingency, and any discounts.
  6. Click Calculate, then export CSV or PDF.

Formula used

This model estimates total assignment cost across all temps.
  • Weekly wages = (RegularHours × Rate) + (OvertimeHours × Rate × OvertimeMultiplier)
  • Weekly benefits = (RegularHours + OvertimeHours) × BenefitsPerHour
  • Labor total = (Weekly wages + Weekly benefits) × Weeks × Temps
  • Employer taxes = (Weekly wages × Weeks × Temps) × TaxRate%
  • Fixed fees = (Background + Onboarding + Equipment + Travel) × Temps
  • Agency markup = Labor total × Markup%
  • Overhead = SubtotalAfterMarkup × Overhead%
  • Contingency = SubtotalAfterMarkup × Contingency%
  • Net total = SubtotalAfterMarkup + Overhead + Contingency − Discount

Workforce demand and baseline costing

Temporary staffing is often triggered by demand spikes, coverage gaps, or special projects. Start with headcount, assignment weeks, and weekly hours per worker. Baseline labor cost equals total hours multiplied by the regular hourly rate, then scaled across all temps. For planning, capture the exact shift pattern, minimum guaranteed hours, and premium differentials for nights, weekends, or hazards.

Overtime exposure and schedule stability

Overtime can materially change totals because it compounds rate premiums and tax bases. Estimate expected overtime hours per week, then apply an overtime multiplier to the regular rate. If schedules are volatile, model a conservative overtime scenario and compare it to the target plan. A small weekly overtime increase across many temps can exceed one-time onboarding fees within a few weeks.

Taxes, statutory costs, and benefit loading

Employer taxes typically apply to wages, so separate wages from benefit load when possible. Include payroll taxes, statutory contributions, and required insurance premiums as a percentage of wages. Benefits per hour can represent paid breaks, holiday accrual, stipends, or employer-paid coverage. Converting these to an hourly load keeps costs comparable across different durations and schedules.

Agency markup and pass-through fees

Agency markup is commonly calculated on billable labor, while some items are pass-through. Track background checks, onboarding and training, equipment, badges, and travel support as per-temp fees. If your contract limits markup to wages only, adjust inputs so benefits and fees are treated separately. The component breakdown helps audit what is driving the bill rate.

Budget controls and decision insights

Use overhead and contingency to reflect supervision time, tools, facilities, and risk buffers. Review effective hourly cost to compare temps with overtime, contractors, or permanent hires. Document assumptions, rerun scenarios when rates change, and export results for approvals. Track planned versus actual hours weekly, reconcile invoices line by line, and address variances quickly to strengthen cost transparency across teams. Set a variance trigger, such as 3–5%, to flag unexpected overtime or fee creep. When budgeting, compare at least three scenarios: target, conservative, and worst case. This supports faster approvals and clearer vendor negotiations for staffing levels, rates, and durations.

FAQs

Does the calculator assume markup applies to all costs?

It applies markup to the combined wages and benefits total. If your contract marks up wages only, set benefits per hour to zero and add benefits into overhead or fixed fees to mirror your billing structure.

Should employer taxes be applied to overtime wages too?

Yes, overtime wages are still wages, so taxes generally apply. If your tax base excludes specific premiums in your jurisdiction, reduce the employer tax rate to an effective blended rate that matches your payroll reports.

How do I model shift differentials or hazard pay?

Increase the regular hourly rate by the average premium per hour, or add the premium into benefits per hour. For mixed shifts, compute a weighted average based on planned hours in each differential category.

What fixed fees should I include for temps?

Common items include background checks, onboarding time, badges, uniforms, equipment, drug tests, and travel support. Add only fees you pay directly, then keep pass-through items separate if invoices show them as reimbursables.

What does effective hourly cost represent?

It is the net total cost divided by total scheduled hours across all temps. Use it to compare alternative staffing options, evaluate agency proposals, and identify whether overtime, markup, or overhead is inflating your blended rate.

How can I use exports for approvals and audits?

Download CSV for spreadsheet review and PDF for stakeholders. Attach the exported summary to purchase requests, then compare invoice totals to the calculator breakdown. Updating assumptions after each cycle improves future forecasts and vendor accountability.
