The short answer: attrition is the percentage of your room block you are contractually obligated to fill — and if you fall short, you pay for the empty rooms. The details of how it is measured decide whether that clause is fair or a trap.
TL;DR: Negotiate cumulative (not night-by-night) pickup, a realistic allowance, and a resell credit before you sign.
The three clauses that move the money
- Attrition percentage. 80% is common; whether it is measured on rooms, revenue, or room-nights changes your exposure dramatically.
- Cumulative vs. nightly pickup. Cumulative measures the block as a whole; nightly penalizes you for every soft night even if the total lands.
- Resell credit. If the hotel resells rooms you released, you should be credited — many contracts stay silent on purpose.
Frequently asked questions
Is attrition negotiable?
Almost always — the first draft favors the hotel. Allowance, measurement basis, and resell credits are all standard points to negotiate.
