ADR Calculator is useful when you want a fast answer without losing sight of the assumptions behind it. It calculates average daily rate for sold rooms from room revenue and the number of rooms sold.

What this calculator does

ADR Calculator calculates average daily rate for sold rooms from room revenue and the number of rooms sold. The visible inputs are rooms revenue earned and number of rooms sold. Its result is driven by those values, so the calculation can be reproduced or stress-tested without relying on a hidden live-data feed.

How to use it

Enter Rooms revenue earned and Number of rooms sold. Keep all monetary inputs in the same currency; the currency selector formats results and does not perform foreign-exchange conversion. Before calculating, recheck Rooms revenue earned, Number of rooms sold against the source values you intend to model. Use the labels on ADR Calculator as the source of truth and recheck any prefilled value before relying on the result.

How the calculation works

ADR = room revenue ÷ rooms sold. ADR Calculator applies that relationship only to the inputs represented on its form. If the result looks surprising, verify the entered values, units, and signs before interpreting the number.

Example

If a hotel earns $24,000 of room revenue from 150 rooms sold, ADR is $160 per sold room. The example is a math check for ADR Calculator; replace the sample values with your own inputs rather than treating the example as a target or recommendation.

How to interpret the result

A higher ADR means more room revenue per occupied room, but it does not show occupancy or total revenue by itself. ADR is best read alongside occupancy and RevPAR when evaluating hotel performance. The number is most useful when compared with another scenario built from the same definitions.

Limitations and notes

Use room revenue consistently; taxes, food and beverage, resort fees, cancellations, comps, and other non-room revenue can distort ADR if mixed into the numerator. Zero rooms sold cannot produce a meaningful ADR. Recalculate when rates, prices, balances, dates, or policy assumptions change.
