Fully Burdened Labor Rate

A fully burdened labor rate is the all-in hourly cost or billing rate that includes an employee's base direct labor rate plus all applicable indirect cost pools (fringe benefits, overhead, and G&A) and contractor fee, representing the total price per hour the government pays for that labor category or the total cost the contractor incurs when an employee charges an hour directly to a contract.

What is a Fully Burdened Labor Rate?

The fully burdened rate is the number that actually appears in contract pricing. When a T&M contract lists $145/hr for a Senior Program Manager LCAT, that is the fully burdened billing rate. It is constructed by applying a series of multipliers to the base direct labor rate: fringe benefits (payroll taxes, health insurance, retirement contributions), overhead (facilities, direct management, equipment), G&A (corporate functions such as finance, HR, legal, and BD), and profit or fee.

The general structure is: Direct Labor Rate × (1 + Fringe Rate) × (1 + Overhead Rate) × (1 + G&A Rate) × (1 + Fee Rate). The precise calculation structure varies by the contractor's accounting system, some contractors apply fringe only on direct labor, while overhead and G&A are applied on different bases (total cost input or value added base). FAR Part 31 and CAS define allowable bases for each pool.

"Wrap rate" is a shorthand expression of the total multiplier: if a $50/hr direct labor cost results in an $85/hr billing rate, the wrap rate is 1.70 (or 170%). Contractors use wrap rates to quickly benchmark their cost structure against competitors and to price labor categories without recomputing every indirect rate from scratch.

For GSA Schedule pricing, the fully burdened rates in the approved pricelist reflect the all-in billing rates including Industrial Funding Fee (IFF). For direct award IDIQs and cost-plus contracts, the structure separates direct labor, fringe, overhead, G&A, and fee into distinct proposal line items for government verification.

Why Fully Burdened Labor Rates Matter for Government Contractors

A contractor whose fully burdened rates are above market loses on price-competitive T&M task orders. A contractor whose rates are unrealistically low during the proposal phase will face margin compression during performance when actual indirect costs exceed the rates applied at pricing time. Understanding how the firm's rates compare to the GSA CALC market (calc.gsa.gov) and to historical contract awards in FPDS is central to both price-to-win analysis and responsible pricing decisions.

Example

A mid-tier professional services firm builds a fully burdened rate for its Systems Engineer II LCAT. Direct labor rate: $65.00/hr. Fringe (31%): $20.15. Subtotal: $85.15. Overhead (22%): $18.73. Subtotal: $103.88. G&A (11%): $11.43. Subtotal: $115.31. Fee (9%): $10.38. Fully burdened billing rate: $125.69/hr. Wrap rate: 1.934. The proposal team checks GSA CALC to confirm that Systems Engineer rates in the DC metro market range from $118 to $147/hr, confirming their rate is within the competitive zone.

Frequently Asked Questions

Can fully burdened rates change from year to year on a multi-year contract?

Yes. Most multi-year contracts with T&M or cost-type CLINs include annual escalation provisions. The fully burdened rates for each option period are typically calculated by applying an annual escalation factor (often 3% for labor and 2-3% for non-labor) to the prior period's rates. Some contracts use the Employment Cost Index (ECI) or Consumer Price Index (CPI) as the escalation basis. The escalated rates must be proposed for each option period and appear in the cost/price volume.

How do DCAA-approved indirect rates relate to fully burdened billing rates?

On cost-type contracts, the contractor bills the government using provisional indirect rates (approved billing rates) during contract performance, then adjusts when final audited indirect rates are established. If final rates are lower than the provisional billing rates, the contractor owes the government a refund; if higher (within allowable limits), the government may owe the contractor additional cost recovery. On T&M contracts, the fully burdened rate in Section B is a fixed billing rate regardless of actual indirect cost performance, the contractor absorbs any variance between actual and proposed indirect rates.

What is a "loaded labor rate" versus a "fully burdened rate"?

These terms are often used interchangeably, but in some contexts "loaded rate" includes only fringe and overhead (not G&A or fee), while "fully burdened" always means all indirect costs plus fee are included. When evaluating competitor pricing or reviewing contract vehicles, clarifying which costs are included in a stated "loaded" or "burdened" rate is important, two contractors quoting similar loaded rates may have very different fully burdened rates depending on their G&A and fee structures.

How are fully burdened rates disclosed in GSA Schedule contracts?

GSA Schedule contractors submit a Price Proposal template showing their basis of estimate for each LCAT rate, including the direct labor rate and all indirect rate pools. GSA negotiates the rates and approves a final pricelist. The approved fully burdened rates, including the 0.75% Industrial Funding Fee (IFF) passed through to ordering agencies, are published on GSA Advantage and GSA eLibrary for market transparency. Competitors and agencies can view any Schedule contractor's approved rates as part of the public pricelist.
