What is a price escalation clause?
A price escalation clause is a term in a supplier contract that lets the agreed price rise over the life of the contract by a rule both parties accepted, such as a fixed percentage on each anniversary or the change in a named price index. It protects the supplier against rising costs and gives you a ceiling on how quickly the price can move. If your job is to hold suppliers to what was agreed, the clause is also the rule you check every later invoice against, because an increase that does not follow it exactly is an overcharge, however small it looks.
What kinds of escalation clause appear in supplier contracts?
Clauses generally take one of three forms, the same three the Federal Acquisition Regulation describes for fixed-price contracts with economic price adjustment: an adjustment based on the supplier’s established prices, one based on its actual costs of labor or material, and one based on a cost index the contract names. Private supplier contracts also often use a fixed step, a stated increase on each anniversary of the start date, which needs no index at all.
- Fixed step: the price rises by a stated amount or percentage on a stated date, usually each anniversary.
- Index-linked: the price moves with a published index, such as a Consumer Price Index or a Producer Price Index, between two named months.
- Cost-based: the price moves with the supplier’s documented cost of a named input, which the supplier must be able to show you.
- Established price: the price follows the supplier’s published price list, often less a discount that stays fixed.
A fixed step is the easiest kind to check and also the easiest to get wrong without anyone noticing, because the arithmetic looks too simple to question.
What should a price escalation clause say?
A clause you can actually check names six things: the price it adjusts, the index or step, the months compared, how often the price moves, the formula, and any cap or floor. The Bureau of Labor Statistics guide on how to use the Consumer Price Index for escalation lists the same elements and warns that a bare reference to “the CPI” is ambiguous, so a well-drafted clause names the full series, its geographic area and whether it is seasonally adjusted. The same guide recommends indexes that are not seasonally adjusted, because seasonally adjusted figures can be revised for years after their first publication.
Check, too, which part of the price the clause covers. A lease may allow base rent to rise while operating expenses follow a separate rule, and a supply contract may allow the price of materials to rise while the labor rate stays fixed. An increase applied to a part of the invoice the clause never mentioned is an easy error to make, and easy to overlook precisely because the percentage itself is correct.
For goods and materials, the BLS price adjustment guide for contracting parties adds two points worth writing into the clause: which version of the index applies, since Producer Price Index figures can be revised for up to four months after they first appear, and what happens if the named series is discontinued.
How do you work out an index-linked increase?
You take the index for the later month the clause names, subtract the index for the earlier month, divide the difference by the earlier figure and multiply by 100, which gives the percentage change to apply to the price. The BLS escalation guide works through an example in which an index moves from 229.815 to 232.945, a rise of 3.130 index points and a change of about 1.4%. Apply the percentage, never the point change, because the guide treats them as different numbers and a contract almost always means the percentage.
Then apply any cap or floor. When the clause caps each increase at a stated percentage, the price can rise by the index change or the cap, whichever is lower, and a floor works the opposite way. A clause with no floor may also allow the price to fall when the index falls, which a supplier is unlikely to mention on its own.
Worked example: the office lease at Larch & Plover
Larch & Plover Advisory is an invented company, one of the Demo companies Ressura uses to demonstrate its checks, and every figure below is made up for the example. It is a management consultancy in Denver that leases a 3,100 square foot suite from Union Station Office Partners on a 36-month lease.
The lease bills two lines each month, base rent of $9,815.00 and $1,420.00 for operating expenses and parking, so the monthly invoice in the first year is $11,235.00. Its escalation clause reads: “Base rent rises 3 percent on each anniversary of the commencement date.”
What the clause allows in year two. Base rent rises by 3 percent of $9,815.00, which is $294.45, to $10,109.45. The operating expenses line is not base rent, so it remains $1,420.00, and the correct monthly invoice for year two is $11,529.45.
Error one: the increase applied to the whole invoice. Suppose the landlord’s billing system applies 3 percent to the entire $11,235.00 and bills $11,572.05. The percentage and the date are both correct, so the invoice passes a quick review, but it is $42.60 a month more than the lease allows, which adds up to $511.20 over year two.
Error two: the increase billed a month early. If the invoice for the final month of year one already carries the new amount, Larch & Plover pays $11,572.05 for a month that should cost $11,235.00, which is $337.05 too much on that one invoice.
Error three: the error compounds. In year three the correct base rent is 3 percent above $10,109.45, which is $10,412.73 rounded to the cent, and the correct invoice is $11,832.73. A landlord who escalates last year’s overbilled total instead bills 3 percent above $11,572.05, which is $11,919.21, so the difference has grown to $86.48 a month, or $1,037.76 over year three.
If the increase is applied to the whole invoice on the first anniversary and compounded on the second, Larch & Plover pays $1,548.96 more than the lease allows over its final two years, although every one of those invoices looks reasonable on its own. The only way to see it is to calculate the increase again from the clause, starting from the base rent the lease originally set.
How do you check invoices after an escalation date?
You calculate the price the clause allows before the first invoice under it arrives, then compare each invoice with that price, line by line, from the escalation date onward. Start by recording every anniversary or index date in the contract in your calendar, so the first invoice after each one gets a careful look rather than a routine approval at the matching step of the procure-to-pay process. Always work each year’s increase out from the price the contract originally set, never from last year’s invoice, so an earlier error cannot carry forward into the new figure.
- Record each escalation datePut every anniversary or index date in your calendar.
- Work it out from the original priceNever from last year’s invoice, so an earlier error cannot carry forward.
- Apply it only to the lines namedFees, freight and operating expenses stay where the contract puts them.
- Compare every invoice, line by lineA change on any other date needs an amendment or price notice to explain it.
Apply the increase only to what the clause names, and confirm that every other line, such as fees, freight or operating expenses, stays where the contract or its own separate rule puts it. For an index-linked clause, look up the named series for the named months yourself, and confirm both the percentage and any cap before you accept the supplier’s figure. Finally, line up the same item across several invoices, because a price that changes on any date other than the escalation date needs another document, an amendment or a price notice, to explain it.
That last comparison also catches price drift, the gradual rise between invoices that no document explains. For the complete line-by-line comparison, see how to check supplier invoices against agreed prices, and for the broader warning signs, how to tell if a supplier is overcharging you.
What do you do when the increase is wrong?
You raise it with the supplier in writing, with the clause, the invoice and your calculation side by side, and ask for a credit note covering the difference on every invoice it affects. Show the original price, the percentage or index months, the price the clause allows and the price billed, so the supplier can follow each step and agree with it. Raise it inside the dispute window your contract allows, because a late claim is easier for a supplier to refuse, and file the reply with the contract for the next anniversary.
If the supplier never applied an increase it was entitled to, record that as well, as a separate figure. It may be billed later as a catch-up, and it is never subtracted from what the supplier owes you on lines billed above the clause.
What should you ask for when you negotiate one?
Ask for a clause you could check from the contract alone: the exact series and months for an index, a cap on each increase, a floor if the index can fall, and the parts of the price it covers, named individually. Ask, too, for written notice of each increase, with the calculation, before the first invoice that carries it. A clause that says only “prices may be adjusted annually” gives you nothing to check against, so it is worth negotiating before you sign rather than disputing after the first increase.
How does Ressura help with escalation clauses?
When you add an agreement to the Data Room, Ressura reads its terms, including any price change on renewal as an escalation term, and shows each value it read for you to review. The Procure-to-Pay Module then checks every unit price on a supplier invoice against the price your agreement sets for that item on that date, applies amendments from their start dates, and raises a price that moves between invoices, by more than the tolerance you set, with no amendment, notice or new agreement behind it, so an increase reaches you with the documents beside it. Any gap is shown in dollars with the arithmetic, and if every line matches, the result reads All in order and lists exactly what was checked.
