Linen Service Calculator

Hotels and other hospitality operations don't launder a set of linens per room per day — they launder linens for the rooms that were actually occupied, so this calculator starts from occupied-room count rather than total room count. It multiplies your total rooms by the occupancy percentage to get daily occupied rooms, then multiplies that by the weight of one complete linen set (sheets, pillowcases, towels — whatever "one set" means for your property) to get daily pounds of linen processed. Monthly and annual costs come from that daily weight times your per-pound service rate, scaled by 30 and 360 days respectively — a simplification that treats every month as a flat 30 days rather than tracking the actual calendar, so it's an estimate suited for budgeting, not for reconciling an invoice line by line.

Separately, the calculator computes total par sets — the total inventory of linen sets you need on hand, found by multiplying total rooms (not occupied rooms) by your par level (sets per room in rotation, typically 2-5). Par levels exist so that soiled linen can be in the wash while clean linen is already on the bed; a higher par level buys more buffer against laundry-service delays at the cost of more linen sitting in inventory. The most common mixup is confusing the "sets per room" par figure with the daily usage rate — par is a static inventory target that should stay fixed regardless of occupancy swings, while the daily linen weight and its downstream costs scale directly with how full the property actually is on a given day.
