Calculating Your Fully-Loaded Labor Rate: A Step-by-Step Guide for Contractors
The seven components of a fully-loaded labor rate, where to find each input, and why memorized multipliers cost contractors money on every billable hour.
Most contractors carry around a "loaded labor multiplier" in their head — 1.4x, 1.5x, "double the wage and call it good." Few can explain where the number comes from. When it's wrong, the contract loses money on every billable hour, every shift, for the life of the contract.
This article walks through how to build a fully-loaded labor rate from scratch using a worked example, and explains where every cost component comes from so you can source accurate numbers for your own business.
1.What "Fully-Loaded" Actually Means
The fully-loaded labor rate is the total hourly cost to employ a worker, including base wage, payroll taxes, insurance, fringe benefits, and any paid time off — everything you pay because that person is on payroll.
It's distinct from two other rates contractors regularly confuse with it:
Base wage — what shows on the employee's paystub. The hourly rate before any employer-side costs.
Billable rate — what you charge the client. Base wage + employer costs + overhead allocation + profit margin.
The relationship looks like this:
Base Wage → Loaded Labor Rate → Overhead-Adjusted Rate → Billable Rate
Each step adds a layer of cost or markup. This article covers the first transformation only: turning a base wage into a fully-loaded labor rate. For the overhead and margin layers, see Article 1: How to Price a Government Contract Bid.
2.The Seven Components of a Loaded Labor Rate
Every fully-loaded labor rate is built from the same seven components:
- Base wage — what you pay the employee per hour.
- FICA (Federal Insurance Contributions Act) — employer share of Social Security and Medicare. 7.65% of wages (6.2% Social Security + 1.45% Medicare).1
- FUTA (Federal Unemployment Tax) — 0.6% effective rate on the first $7,000 of annual wages per employee, capped at $42/year.2 Spread across 2,080 annual hours, this is about $0.02/hour.
- SUTA (State Unemployment Tax) — varies by state and your experience rating. New employers in Georgia pay 2.7% on the first $9,500 of wages.3
- Workers compensation insurance — varies dramatically by industry NCCI class code. Janitorial work runs around $3/$100 of wages; HVAC technicians average $3.14/$100; sheet metal work can hit $10-$12/$100.4
- Health & welfare / fringe benefits — for SCA-covered contracts, currently $5.55/hour (or $5.09/hour for contracts subject to EO 13706 paid sick leave).5 For private-sector work, whatever your company benefits cost per employee divided by hours worked.
- Paid time off (PTO) — vacation, holidays, sick leave. Often calculated as a percentage of base wage. Common ranges: 5% (10 days/year), 7.5% (15 days), 10% (20+ days).
Optional add-ons: 401(k) employer match, life insurance, training time, uniform costs, tool allowances.
One thing not included in the loaded labor rate: overhead. Rent, software, administrative payroll, insurance premiums beyond workers comp — those are allocated separately when you build the billable rate. For overhead allocation, see Article 1 Section 4.
