Contractors bidding an overseas contract for the first time often want a single number for DBA. There isn't one — but the structure behind the number is straightforward enough to estimate against once you understand the three variables that drive it.
Rate per $100 of payroll
DBA is priced like other workers' compensation lines: a rate applied against payroll, expressed per $100. Your total premium is a function of how much payroll you have in each job classification, and what rate applies to that classification in that country.
This means payroll estimates matter. Understate them and you face an audit adjustment later; overstate them and you tie up cash in premium you didn't need to pay upfront.
Variable one: job classification
Classification is the largest single driver. An administrative role working inside a secured facility and an armed security operator conducting movements outside the wire represent enormously different loss expectations, and rates reflect that.
Common classification groupings include administrative and clerical, logistics and supply, construction and skilled trades, technical and IT, medical support, aviation support, and security. The spread between the lowest and highest classifications is substantial.
Accurate classification is a financial issue and a compliance issue at once. Misclassifying a security role as administrative to reduce premium creates audit exposure and can create disputes at claim time.
Variable two: country of performance
Where the work happens changes the rate. A contract performed in a stable host nation with functioning infrastructure prices differently from one performed in an active conflict environment, where war-hazard considerations enter the picture.
If your contract spans multiple countries, expect the submission to break payroll out by country rather than treating it as one pool.
Variable three: the specifics of your operation
Beyond classification and geography, underwriters look at headcount, contract duration, prior loss history, the safety and security protocols in place, whether personnel are housed on secured facilities, and the nature of movements required by the work.
Loss history matters more than contractors expect. A clean record on prior overseas work is a genuine asset in negotiation.
Audits and payroll reporting
Most DBA policies are auditable. You provide estimated payroll at binding and report actual payroll during and after the policy period, with premium adjusted accordingly. Contracts that grow, shrink, or add countries mid-term will produce adjustments.
The practical discipline is keeping payroll records clean by classification and country throughout the contract rather than reconstructing them at audit.
What this means for bidding
Get an indication before you finalize your bid, not after you win. Contractors who price DBA as an afterthought sometimes discover the coverage cost erodes a margin they'd already committed to. A realistic estimate during proposal development is a competitive advantage, not an administrative chore.
