Tell us about your operation, price a handful of priority SKUs, and we'll
show you where you sit against the panel of operators Percy already works with.

Step 2 of 4 · Your prices
Enter the prices you actually pay
We've tailored the priority SKUs below to your sector — these are the items whose
prices best signal overall procurement performance for operators like you. Commodity items
(butter, eggs, milk etc.) are shown for per-SKU heat but don't drive the headline saving.

Green = below market · Amber = at market · Red = above market.
Priority items (pink edge) drive the headline prediction. Commodities are diagnostic only.

About this prediction.
v14.0 is calibrated on our first cohort of operators with audit-realised savings as the
benchmark — not theoretical hybrid headroom.
This is an indicative figure, not a maximum.
Three reasons your true headroom may be larger:
Sector coverage varies. Some sectors are better represented in our first cohort than others. Predictions for sectors where our panel is still thin may underestimate the true headroom.
The calculator only sees priority SKUs. It excludes long-tail purchases, specialty ingredients, packaging and niche SKUs that Percy often finds savings in during a full audit.
Already-optimised operators have hidden long-tail headroom. If your priority-SKU prices are below panel, the model holds your prediction at your sector cohort base — because the long-tail typically still carries savings.
How accuracy improves over time
Mean absolute prediction error: 5.7pp · median 4.1pp
58% of operators predicted within ±5pp; 86% within ±10pp · statistical significance p=0.005
The model captures roughly 11% of operator-to-operator variation.
