Our displacement analysis guide covers the method — the four numbers, the formula, the break-even rate. This is the companion piece: one realistic group ask taken all the way through, with every complication the clean textbook version skips — commission, comp rooms, concessions, banquet profit, and the wash adjustment that quietly flips the verdict. Follow along with your own numbers.
A 120-room upscale hotel. Sales brings a corporate group: 60 rooms per night, Tuesday–Thursday, at $139, booked through an agency at 10% commission, with a 1-per-40 comp room policy, two suite upgrades plus amenities (~$600 of concessions across the stay), and a two-day banquet lunch program worth $9,000 gross. Answer needed by Friday.
Everything rests on what you would honestly sell anyway — from pickup history and current pace, not from hope:
| Night | Transient demand (rooms) | Transient ADR |
|---|---|---|
| Tuesday | 105 | $189 |
| Wednesday | 112 | $195 |
| Thursday | 82 | $175 |
With the 60-room block, only 60 rooms remain for transient. Displaced = min(demand, 120) − min(demand, 60). Value each displaced room at its ADR minus variable cost ($22/room here — housekeeping, amenities, breakfast):
| Night | Displaced rooms | Contribution each | Displaced value |
|---|---|---|---|
| Tuesday | 105 − 60 = 45 | $189 − $22 = $167 | $7,515 |
| Wednesday | 112 − 60 = 52 | $195 − $22 = $173 | $8,996 |
| Thursday | 82 − 60 = 22 | $175 − $22 = $153 | $3,366 |
| Total | 119 room-nights | $19,877 |
Note the shape: Wednesday does the damage. Thursday barely displaces. This per-night view is what makes the counter-offer possible later.
Work in contribution, same as the transient side:
Group contribution at face value ≈ $20,349 vs $19,877 displaced — ahead by about $470. On the booking report this looks like a yes.
Groups rarely fill their block. Your wash tracking says this account type materializes about 85% — but you hold all 60 rooms until cutoff, so the displacement stays. You displace on the block and get paid on the pickup:
Displacement analysis isn't a yes/no machine — it prices the deal. Three levers, from the per-night table: rate — at $159 (net $143.10, contribution $121.10), the expected-pickup math lands about $440 positive: that's your floor, quote $159–$169; pattern — shifting to Wednesday–Friday halves Wednesday displacement's weight because Friday barely displaces (re-run the table for any shift); and terms — 90% attrition, a guaranteed F&B minimum, and a reviewable block (release unsold rooms at 30 days) all shrink the wash gap that killed the $139 version. The counter that went back: $159, 90% attrition, F&B minimum guaranteed — or $145 on a Sunday–Tuesday pattern. Both work on the math; sales picks the one the client can sell.
The free displacement calculator handles the one-night version in your browser. The Group Displacement Calculator ($39) is this entire walkthrough as a working spreadsheet — multi-night model with per-night forecasts, commission and variable-cost fields, the wash adjustment, a quote builder, and the wash-tracking sheet that gives you a real materialization rate instead of a guess. The concept and the break-even formula live in the displacement analysis guide.
