Enter the marginal costs of accommodating one additional guest — extra breakfast, additional linen and laundry, higher utility use — and your target margin. The tool calculates a recommended per-extra-guest surcharge and shows how it compares to your standard room-only rate.
| Cost Item | Cost per Guest |
|---|
Only include costs that genuinely change with one extra guest — additional breakfast, extra linen and laundry, incremental utility use. Do not include a share of fixed room costs (rent, rates, base staffing) — these are already covered by the standard rate.
A surcharge set too high discourages families and groups from booking, or encourages under-declaring guest numbers. A surcharge set too low leaves margin on the table on every group booking. The target margin % lets you tune this balance to your market.
Many properties apply a lower or waived surcharge for young children, given their genuinely lower marginal cost (breakfast, linen use) compared to an additional adult. Consider a simple age-tiered structure if your guest mix includes many families.
Extra guest surcharges should be clearly stated at the point of booking, not added as a surprise at check-in. Ambiguity here is one of the most common sources of guest complaints and negative reviews in accommodation.
