Procurement savings: how to measure and report them
Procurement savings are a reduction in total cost of ownership (TCO) through better prices, terms, and specifications, as well as optimization of demand and processes. Distinguish realized from negotiated savings and cost reduction from cost avoidance.
What the metric measures
The effect of price reductions, rebates, better Incoterms, VE/VA, supplier consolidation, alternative materials, optimized MOQ/batch sizes and logistics, and lower quality and energy costs.
Calculation
- Savings, % = (Baseline − Actual) / Baseline × 100 (excluding VAT, single currency)
- PPV = (Standard price − Actual) × Quantity; break it down into price and mix
- TCO savings = (Price + logistics/duties + storage + quality + energy + disposal)Baseline − (…)Actual
- Rebates/cash discounts — by accrual/receipt date; track cost avoidance separately
- FX/inflation — calculate net-of-inflation/FX; lock in the exchange rate/baseline
- Realized vs Negotiated — savings are “realized” only once they are reflected in orders/invoices
Clarify the baseline: historical, budget, market index, or should-cost; document the accounting rules.
Calculation example
Last year steel was bought at 42,000 per tonne, after a tender at 39,900. For 120 tonnes a year the saving = (42,000 − 39,900) × 120 = 252,000, or 5% of the baseline. If market prices fell 4% over the same time, purchasing’s real contribution is about 1%.
Data sources
ERP/1C (PO, GR/IR), accounting (GL), contracts/catalogs, TMS (rates/Incoterms), WMS (storage), QMS (cost of quality), energy costs, market indices.
Interpretation
- Savings↑ — effective negotiations, VE/VA, consolidation, optimized batches/logistics
- Savings↓ — inflation/FX, “maverick spend,” over-specification, more expensive logistics
- Check the impact on COGS, margin, and CCC (MOQ/lead time → inventory)
Useful breakdowns
- Categories (direct/indirect), suppliers, countries
- Incoterms/transport mode, currency
- On-contract/off-contract; SKUs/material groups
- Savings type (price/TCO/avoidance); status (negotiated/realized)

How to set targets
Aim for 2–5% (direct) and 5–10% (indirect) net-of-inflation; ≥80% of spend under management; maverick ≤ 5–10%. Maintain a savings book with the baseline, method, exchange rate, and realization schedule.
Common mistakes
- Double counting, wrong baseline/mix
- Counting FX/inflation as “savings”
- Ignoring TCO; booking avoidance to the P&L
- Mixing amounts with/without VAT, different currencies
- Savings at the cost of failing OTIF/quality
Questions for discussion
- Which categories account for 80% of the potential?
- What is the effect of supplier consolidation and changing Incoterms?
- Where will VE/VA deliver the greatest TCO effect without quality risk?
- How can negotiated savings be turned into realized ones in the coming quarters?
