CBA (Cost Benefit Analysis)

What is a Cost Benefit Analysis (CBA)?

A Cost Benefit Analysis is a structured way of weighing what a decision will cost against what it is expected to deliver. In federal acquisition it is the tool agencies use to justify choosing one course of action over another: buy versus build, one system versus another, or whether an investment is worth making at all. Costs and benefits are estimated over time and compared on a common basis so the choice can be defended.

What it weighs

A sound CBA captures more than the purchase price. It accounts for life-cycle costs, including operation, maintenance, and disposal, and sets them against quantifiable benefits such as savings or efficiency, plus harder-to-measure benefits like improved mission outcomes. The honest ones also state their assumptions and the alternatives considered, since a CBA that only looks at the preferred option is not really an analysis.

Why it matters to contractors

When you propose a solution, you are implicitly making a cost-benefit argument, so make it explicit. Framing your offer in terms of total value over its life, not just bid price, speaks the language evaluators use internally to defend an award. A lower sticker price does not always win if a competitor shows stronger benefits over time. It connects to early estimates like a rough order of magnitude.
