Certified Service Technician Labor Rate Calculator

Calculate the appropriate billable labor rate for a certified service technician based on base wage, overhead costs, labor burden, and desired profit margin.

Base Hourly Wage ($/hr)

Labor Burden Rate (%)Payroll taxes, benefits, insurance, etc.

Overhead Rate (%)Rent, utilities, equipment, admin costs as % of labor cost

Certification Premium ($/hr)Additional hourly cost for certifications/training

Annual Billable HoursProductive hours billed per year (typical: 1,200–1,600)

Total Annual Hours PaidTotal hours paid per year (typical: 2,080)

Desired Profit Margin (%)Net profit as a percentage of the billable rate

// ── Core Calculations ──────────────────────────────────────────────────────

// 1. Effective hourly cost = (base wage + cert premium) × (1 + burden rate) // This is the true cost per hour PAID (including all burden) var effectiveHourlyCost = (baseWage + certPremium) * (1 + burdenRate / 100);

// 2. Annual labor cost (total cost for all paid hours) var annualLaborCost = effectiveHourlyCost * annualHours;

// 3. Annual overhead cost = annual labor cost × overhead rate var annualOverheadCost = annualLaborCost * (overheadRate / 100);

// 4. Total annual cost to recover var totalAnnualCost = annualLaborCost + annualOverheadCost;

// 5. Cost per billable hour (spread total cost over only billable hours) var costPerBillableHour = totalAnnualCost / billableHours;

// 6. Billable rate with profit margin // Rate = Cost per billable hour / (1 - profit margin %) // This ensures profit margin is a % of the selling price (rate), not cost var billableRate = costPerBillableHour / (1 - profitMargin / 100);

// 7. Utilization rate var utilizationRate = (billableHours / annualHours) * 100;

// 8. Annual revenue at this rate var annualRevenue = billableRate * billableHours;

// 9. Annual profit var annualProfit = annualRevenue - totalAnnualCost;

// 10. Markup on cost (for reference) var markupOnCost = ((billableRate - costPerBillableHour) / costPerBillableHour) * 100;

// ── Format output ────────────────────────────────────────────────────────── function fmt(n, dec) { dec = dec === undefined ? 2 : dec; return n.toLocaleString('en-US', {minimumFractionDigits: dec, maximumFractionDigits: dec}); }

#### Formulas Used

1. Effective Hourly Cost (with Burden): Effective Hourly Cost = (Base Wage + Certification Premium) × (1 + Burden Rate)

2. Annual Labor Cost: Annual Labor Cost = Effective Hourly Cost × Total Annual Hours Paid

3. Annual Overhead Cost: Annual Overhead Cost = Annual Labor Cost × Overhead Rate

4. Total Annual Cost to Recover: Total Annual Cost = Annual Labor Cost + Annual Overhead Cost

5. Cost per Billable Hour: Cost per Billable Hour = Total Annual Cost ÷ Annual Billable Hours (Spreads all costs — including non-billable time — across only productive billable hours)

6. Recommended Billable Rate: Billable Rate = Cost per Billable Hour ÷ (1 − Profit Margin %) (Profit margin is expressed as a percentage of the selling price, not cost)

7. Utilization Rate: Utilization Rate = (Annual Billable Hours ÷ Total Annual Hours Paid) × 100
