Stop silent price drift: understand escalators, spot red flags, and negotiate caps and documentation (not legal advice)
By the end of this resource you will:
Important: This is operational education, not legal advice.
Pick one vendor contract and do this:
A price escalator clause is a rule that says:
Your price will increase over time, under certain conditions.
Escalators aren't automatically "bad." The problem is when they are:
Beginner rule: If you can't explain how the price increases in one sentence, the clause is dangerous.
Example: "Rates increase 5% annually."
Good: predictable, easy to model
Risk: if 5% is too high or compounding over long terms
Negotiation goal: lower %, cap, or tie to a reasonable index.
Example: "Rates increase by CPI annually."
Good: ties increases to inflation
Risk: CPI measure not specified; timing unclear; no cap
Negotiation goal: define the CPI index, define the reference period, add a cap.
Example: "Rates increase by CPI + 2% or CPI, minimum 4%."
Risk: can exceed inflation significantly; often hidden in renewals
Negotiation goal: remove margin/minimum, cap the increase.
Example: "Rates may be adjusted to market."
High risk: "market" is undefined; becomes a blank check
Negotiation goal: replace with defined index + cap + notice requirement.
Example: "Fuel surcharge may apply."
Good: sometimes legitimate for logistics-heavy vendors
Risk: often abused without documentation rules
Negotiation goal: documentation required + formula + cap + frequency limits.
Example: "Materials will be billed at cost plus 20%."
Good: can be legitimate if documented
Risk: dangerous if "cost" is undefined and receipts aren't required
Negotiation goal: receipts required + markup cap + no admin stacking.
Flag any of these:
If you can't answer all 6, the clause needs improvement.
Even "reasonable" increases compound:
5% annually over 3 years is not 15%.
It compounds: year 1 +5%, year 2 +5% on the new base, year 3 +5% again.
Beginner rule: Model at least 3 years for any vendor with multi-year terms.

Subject: Pricing escalator revision request — [Vendor] Hi [Name], To align with our pricing controls, we need the escalator language to be: - Clearly defined (index + reference period) - Applied no more than annually - Capped (hard cap %) - Documented (receipts/formula for any variable surcharge or pass-through) Preferred structure: - CPI-based with a cap of [X%], no minimum, and index defined as [index details] OR - Fixed annual increase of [Y%] with a cap and no additional market adjustments Can you propose updated language or confirm your contracting team can accommodate this? Thanks, [Name]
Use this in a spreadsheet:
| Year | Base annual cost | Escalator % | New annual cost | Increase $ | Notes |
|---|---|---|---|---|---|
| 0 | — | — | — | — | Current |
| 1 | — | — | — | — | — |
| 2 | — | — | — | — | — |
| 3 | — | — | — | — | — |
Formula hint (spreadsheet): New annual cost = prior year cost × (1 + escalator %)
Pass-through charges must include documentation: - receipts or tickets - quantity and unit - date and site - description of materials/services Charges without documentation may be returned or partially approved.
Confidence: High (these are standard pricing control concepts).
Assumptions: You can access pricing exhibits and enforce documentation rules.
Where this can fail: If escalators and surcharges are allowed to stack without review, or if AP pays without checks.
