Profit-driven budgeting builds the plan from an attributed cost model, so each driver, volume, mix, price and cost-to-serve, is set on purpose, instead of inflating last year numbers and inheriting all of last year hidden losses.
A percentage uplift treats a loss-making customer and a star account exactly the same: it grows both. Build the budget from a cost model instead and the conversation changes. You plan which customers to grow, which to re-price, and which to step back from, and the margin target is the sum of deliberate choices rather than a hopeful round number.
The budget inherits a cost-to-serve model, so it already knows what each customer and product really costs.
Volume by segment, planned re-pricing, mix shift, cost-to-serve initiatives. Every assumption is explicit and owned.
The drivers roll up into a margin you can walk a board through, line by line, instead of defending a single percentage.
When actuals diverge, the model says which driver and which dimension moved, so the next budget is sharper than the last.
The budget is the deliberate target. Forecasting is the running projection of where you will land. Both sit on cost-to-serve, so variance is explainable down to the layer and the team.
