Procurement KPI sheet: definitions and formulas
A KPI is only useful when everyone calculates it the same way. This reference gives a plain definition, a formula, and a review frequency for the procurement measures most teams start with. For the reasoning behind choosing them, read the procurement KPIs guide.
Cost and savings
| KPI | Definition | Formula | Review |
|---|---|---|---|
| Savings against baseline | Reduction in price versus the previous price or a reference price. | (Baseline price − awarded price) × quantity | Per award, reported monthly |
| Spend under management | Share of total spend that goes through a controlled, competitive process. | Managed spend ÷ total spend × 100 | Quarterly |
| Price variance | Gap between the agreed price and the price actually invoiced. | (Invoiced price − PO price) × quantity | Monthly |
Process efficiency
| KPI | Definition | Formula | Review |
|---|---|---|---|
| Requisition-to-PO cycle time | Time from an approved requisition to a purchase order being issued. | PO date − requisition approval date | Monthly |
| Sourcing cycle time | Time from issuing an RFQ or auction to making the award. | Award date − RFQ issue date | Per event, reviewed quarterly |
| Touchless invoice rate | Share of invoices that match their PO and receipt without manual work. | Auto-matched invoices ÷ total invoices × 100 | Monthly |
Supplier and risk
| KPI | Definition | Formula | Review |
|---|---|---|---|
| On-time delivery rate | Share of deliveries received on or before the promised date. | On-time deliveries ÷ total deliveries × 100 | Monthly, by supplier |
| Quality acceptance rate | Share of delivered items accepted without rejection or rework. | Accepted units ÷ received units × 100 | Monthly, by supplier |
| Supplier compliance rate | Share of active suppliers with current documents and approvals. | Compliant active suppliers ÷ active suppliers × 100 | Quarterly |
| Spend concentration | How much of a category's spend sits with its largest supplier. | Top supplier spend ÷ category spend × 100 | Quarterly |
Frequently asked questions
Which procurement KPIs should we start with?
Start with five or fewer you can measure reliably, for example savings against baseline, spend under management, requisition-to-PO cycle time, on-time delivery rate, and touchless invoice rate. Add more only when the first set is trusted.
How do we define the savings baseline?
Agree the reference price before the sourcing event: usually the last paid price or a documented market benchmark. Using one definition consistently matters more than which one you choose.
How often should procurement KPIs be reviewed?
Operational measures such as cycle time and invoice matching are usually reviewed monthly. Strategic measures such as spend under management and concentration are reviewed quarterly.
