Subcontractor Labor Cost Calculator
Calculate the total cost of hiring a subcontractor, including base hourly rate, hours worked, overhead burden, markup percentage, and applicable payroll taxes.
Base Hourly Rate ($/hr)
Total Hours Worked
Overtime Hours (included in total)
Overhead Burden Rate (%)
Profit Markup (%)
Payroll Tax Rate (%) (FICA, FUTA, SUTA)
Number of Workers
Calculate
### Cost Breakdown
function subCalc() { const errEl = document.getElementById('sub_error'); const resEl = document.getElementById('sub_result'); errEl.style.display = 'none'; resEl.style.display = 'none';
const hourlyRate = parseFloat(document.getElementById('sub_hourly_rate').value); const totalHours = parseFloat(document.getElementById('sub_hours').value); const overtimeHours = parseFloat(document.getElementById('sub_overtime_hours').value) || 0; const overheadPct = parseFloat(document.getElementById('sub_overhead').value); const markupPct = parseFloat(document.getElementById('sub_markup').value); const taxRate = parseFloat(document.getElementById('sub_tax_rate').value); const workers = parseInt(document.getElementById('sub_workers').value) || 1;
// Validation if (isNaN(hourlyRate) || hourlyRate totalHours) { errEl.textContent = 'Overtime hours cannot be negative or exceed total hours.'; errEl.style.display = 'block'; return; } if (isNaN(overheadPct) || overheadPct '$' + v.toFixed(2).replace(/\B(?=(\d{3})+(?!\d))/g, ',');
const rows = [ ['Regular Hours (per worker)', regularHours.toFixed(1) + ' hrs'], ['Overtime Hours (per worker)', overtimeHours.toFixed(1) + ' hrs @ ' + fmt(overtimeRate) + '/hr'], ['Base Labor Cost (per worker)', fmt(baseLabor)], ['Payroll Taxes (' + taxRate + '%)', fmt(payrollTax)], ['Overhead Burden (' + overheadPct + '%)', fmt(burdenedLabor - baseLabor - payrollTax)], ['Burdened Cost (per worker)', fmt(burdenedLabor)], ['Number of Workers', workers], ['Total Burdened Cost (all workers)', fmt(totalBeforeMkp)], ['Profit Markup (' + markupPct + '%)', fmt(markupAmt)], ['Grand Total Cost', '' + fmt(grandTotal) + ''], ['Effective Billing Rate (per hr)', fmt(effectiveRate) + '/hr'], ];

#### Formula
Base Labor Cost (per worker) = (Regular Hours × Hourly Rate) + (Overtime Hours × Hourly Rate × 1.5) Payroll Tax Cost = Base Labor Cost × Payroll Tax Rate Burdened Labor Cost = (Base Labor Cost + Payroll Tax Cost) × (1 + Overhead Rate) Total Before Markup = Burdened Labor Cost × Number of Workers Grand Total = Total Before Markup × (1 + Markup Rate) Effective Billing Rate = Grand Total ÷ (Total Hours × Workers)
#### Assumptions & References
- Overtime is calculated at 1.5× the base hourly rate per the Fair Labor Standards Act (FLSA) for hours over 40/week.
- The default payroll tax rate of 15.3% reflects the combined employer + employee share of FICA (Social Security 12.4% + Medicare 2.9%); adjust for FUTA (0.6%) and SUTA as applicable.
- Overhead burden covers indirect costs such as insurance, tools, vehicle use, administrative expenses, and benefits — typically 20–40% for contractors.
- Profit markup is applied to the fully burdened cost and typically ranges from 10–25% depending on project type and market conditions.
- This calculator assumes the subcontractor is classified as an employee. For 1099 independent contractors, payroll taxes may not apply — consult IRS Publication 15-A.
