Unit economics is the financial model of a single production unit or transaction — its revenue, direct costs, and contribution margin. It answers whether a business can be profitable at the level of one sale, before scale effects, and is the building block from which credible market sizing and cashflow forecasts are assembled. A strategy whose unit economics don't work at one unit rarely works at a million.
Unit economics anchors the Financial Logic dimension of the BRI Strategy Framework and feeds the Viability judgment in the Desirability–Feasibility–Viability (DFV) evaluation. In Growth Forge® Software it is one of the financial-modeling tools that let teams build credible economics without specialist finance expertise.
