Equal room-night revenue can leave different cleaning costs. Boutique hotel and apartment operators should count departure cleans separately from services during a stay, then multiply each by its own cost assumption. Less work does not automatically mean cash savings: if paid shifts remain unchanged, do not reduce payroll in the calculation. This fictional example helps identify which costs actually change before making a pricing decision. Contribution here means revenue after the listed costs, not the property's net profit.
Define the service unit first
A room-night means one room sold for one night. Here, a departure clean prepares a room for the next guest; an interim service is one scheduled cleaning visit during a stay. These are modelling definitions, not universal standards. Separate towel delivery, full cleaning and waste collection if they involve different costs. Do not change the promised guest service simply to improve the calculation. Oracle's version 24.4 documentation distinguishes service tasks. Mews describes reservation-level cleaning instructions. Both were reopened on 22 October 2026; neither supplies the costs below. They do not establish Stayax capabilities. Record planned and completed services consistently. Exclude cancelled visits from completed work and show repeat cleaning separately.
A calculation you can reproduce
Assume two booking mixes each produce 120 sold room-nights at 100 accounting units per room-night: 120 × 100 = 12,000 units. No currency, tax treatment or market rate is implied. All relevant departures occur within the period, with no stay crossing its boundary. Otherwise align the service period with the revenue period before comparing. Mix A has 60 stays × 2 nights, 60 departure cleans and 60 interim visits. Mix B has 30 stays × 4 nights, 30 departure cleans and 90 interim visits. Both assume one interim visit after each night except departure day. This frequency is an assumption, not a recommendation; rebuild the counts for your service promise. Assume each departure costs 18 units and each interim visit 6, initially treating all of that cost, including labour, as variable with completed tasks. A costs 60 × 18 + 60 × 6 = 1,440. B costs 30 × 18 + 90 × 6 = 1,080. Contribution after those cleaning costs is 12,000 − 1,440 = 10,560 for A and 12,000 − 1,080 = 10,920 for B. B's difference is 360 units. This does not establish that longer stays are always more profitable; revenue and the stated assumptions are held equal.
Recalculate when paid shifts are fixed
Split a departure's 18 units into 12 labour and 6 supplies; split an interim visit's 6 into 4 labour and 2 supplies. If paid shifts do not change, supplies cost 60 × 6 + 60 × 2 = 480 for A and 30 × 6 + 90 × 2 = 360 for B. The variable supplies difference is only 120. The remaining 240 of the first model's difference is a labour allocation difference, not a cash saving. Examine it as capacity. Without a common fixed payroll amount, do not calculate a total contribution for this second model.
Checklist before a decision
- Record service definitions, promised frequency and completed counts for the same period.
- Separate labour, supplies and outsourced work. Never count the same payroll as both fixed and variable.
- Check whether wages, invoices or overtime actually change. Otherwise record released capacity.
- Review the daily departure pattern: fewer tasks across a period can still conceal one busy day.
- Before discounting, calculate demand, revenue changes and omitted expenses separately.
Commission, breakfast, energy, maintenance, tax and fixed overhead are excluded. Do not add laundry again if already included in supplies. The practical decision is to create separate departure and interim cost lines and verify which labour costs are avoidable before changing the booking mix. Compare both models with your own service counts; if no invoice can fall, prepare a work plan rather than a savings budget.
