Demand component
Billed kW × $/kW
Use billed demand after any applicable ratchet or minimum. Excludes other components and taxes.
Choose the tariff quantity, check units, and reconcile the selected charge. Read the demand-charge estimator explanation →
Energy per room-night
Included cost ÷ occupied room-nights
Match service dates and cost boundaries. This spending ratio differs from physical energy efficiency.
Define matching cost, occupancy, fuel, and service-date boundaries. Read the energy cost per occupied room explanation →
Price-component difference
kWh × (fixed $/kWh − assumed index $/kWh)
Positive means the fixed component costs more under your assumption. Compare equal inclusions. The assumed index is a scenario.
Compare equal components under your own index-price assumption. Read the fixed versus index components explanation →
How should you use the results?
Keep the original bill, tariff, occupancy record, or supplier offer beside the output. The demand tool uses a tariff-defined billing quantity. The room-night tool requires matching dates and cost boundaries. The component comparison requires equal inclusions and a clearly labeled assumption.
Read the linked explanations before using these calculations in a budget or purchasing decision. The Hotel Bill Teardown, occupied-room framework, and contract guide provide the wider context.
