Baseline Spend
Baseline spend is the reference level of spending for a category, usually based on historical data, against which savings and future performance are measured.
Before you can claim a saving, you need a fair starting point, and that is what a baseline provides. It is typically built from historical spend over a defined period — often a year — capturing prices, volumes and terms as they were before any sourcing intervention. A clean baseline makes it possible to demonstrate the impact of a negotiation or category project credibly.
Setting a baseline involves judgement: which period to use, how to treat one-off purchases, and how to adjust for changes in volume or scope. Because savings figures are only as trustworthy as the baseline behind them, procurement and finance usually agree the methodology up front. That shared baseline then anchors savings realisation and variance analysis for the category.

- How is a spend baseline set?
- It is built from historical prices, volumes and terms over a defined period, with adjustments for one-offs and scope changes — agreed between procurement and finance so savings claims are credible.
