The “Display per unit” checkbox in the Percent block changes how percentages are calculated and shown. Instead of calculating percentages based on total values, it shows them relative to each operational unit — like per room night, guest, or cover.

Use “Display per unit” if you want to:

• Break down a percentage cost by unit (e.g., linen cost per room or food cost per cover)
• Compare costs across departments or properties with different volumes
• Monitor per-unit efficiency, not just total contribution

Example 1: Laundry Cost per Guest Night

• Laundry total cost: $1,200
• Guest nights: 600
• Revenue: $15,000

With Display per unit:

• $1,200 / 600 guest nights = $2 per guest
• $2 / $25 revenue per guest = 8% per unit

Without Display per unit:

• $1,200 / $15,000 = 8% total

Same percentage, but “Display per unit” clarifies it’s tied to per guest night, not overall totals.

Where it appears:
You’ll find this option in the Planning module when editing a line and choosing the Percent value type. It works together with account links and custom lines.
