Average daily rate is the simplest number in hotel performance reporting and the one most often quoted without its two companions. This hotel ADR calculator takes net rooms revenue, rooms sold and rooms available, and returns ADR, occupancy and RevPAR at once — because those three figures are bound together by an identity, and reading any one of them alone will mislead you.
Arb Digital publishes free calculators for operators who need a defensible number quickly, and hospitality yield is a good example of where the arithmetic is trivial but the definitions do all the work. The industry definitions used here are the published ones; what the tool contributes is showing the relationship between them on your own figures, with no market data, no benchmark rates and nothing assumed about your property.
What This ADR Calculator Does
It divides net rooms revenue by rooms sold to give ADR, divides rooms sold by available room nights to give occupancy, and divides net rooms revenue by available room nights to give RevPAR. It then checks the identity between them and reports it back to you, so you can see that RevPAR really is ADR multiplied by occupancy rather than taking it on trust.
Two extras sit alongside. The first is total revenue per available room, which adds the non-room revenue you enter — food and beverage, meetings, spa, parking — back into the numerator. ADR deliberately excludes all of that, which is why a resort with a large food and beverage operation can look modest on ADR and strong on total revenue. The second is a comparison scenario: enter a target or prior-period ADR and occupancy, and the tool shows what RevPAR those two figures would produce and how it compares with your actual.
Nothing in this page is a market rate. Every figure is one you enter, from your own property management system or from a benchmarking service you subscribe to.
How to Use It
- Enter net rooms revenue for the period. Rooms only. If your report bundles resort fees or parking into the same line, split them out first or your ADR will be overstated.
- Enter the room count and the number of nights. The product is your available room nights. If rooms were genuinely out of order for the whole period, decide whether to exclude them — and be consistent about that decision across periods.
- Enter rooms sold. Occupied room nights, not reservations and not guests. A four-night stay is four rooms sold.
- Add non-room revenue if you want the total revenue per available room figure. Leave it at zero for a pure rooms view.
- Add a comparison ADR and occupancy — budget, last year, or a benchmark you pay for — and press Calculate to see all figures and the comparison update together.
The Formulas and How They Interlock
Three definitions, one identity. ADR = rooms revenue ÷ rooms sold. Occupancy = rooms sold ÷ rooms available. RevPAR = rooms revenue ÷ rooms available. Because rooms revenue appears in the first and third and rooms sold cancels, RevPAR = ADR × occupancy exactly — not approximately, and not as a rule of thumb.
Work the default figures through. A 150-room hotel over 30 nights has 4,500 available room nights. It sold 3,600 of them, so occupancy is 3,600 ÷ 4,500 = 80.00%. Net rooms revenue of $594,000 over 3,600 rooms sold gives an ADR of $594,000 ÷ 3,600 = $165.00. RevPAR is $594,000 ÷ 4,500 = $132.00. Check the identity: $165.00 × 0.80 = $132.00. It closes. Run it backwards too — $132.00 ÷ $165.00 = 0.80, recovering occupancy — and it closes in that direction as well. These definitions are the ones set out in the industry's standard references, including the hotel industry terms published by STR and the Uniform System of Accounts for the Lodging Industry maintained by HFTP, which is the accounting standard that decides what counts as rooms revenue in the first place.
Total revenue per available room follows the same shape with a wider numerator: (rooms revenue + non-room revenue) ÷ rooms available, or ($594,000 + $180,000) ÷ 4,500 = $172.00. It is not an ADR variant and should never be reported as one.
Why ADR Alone Is the Wrong Number to Manage To
Because RevPAR is the product of ADR and occupancy, any decision that raises one usually moves the other. Push rates up and ADR rises while occupancy falls; discount into a soft period and occupancy recovers while ADR drops. Whether the trade was worth making shows up only in RevPAR, which is why RevPAR is the figure most operators manage to and ADR is the figure most often quoted to outsiders.
A concrete case: raising ADR from $165 to $180 — a 9.1% rate increase — while occupancy slips from 80% to 72% produces RevPAR of $180 × 0.72 = $129.60, below the original $132.00. The rate story sounds like a win and the revenue story is not. The comparison fields in the calculator exist precisely so you can test that trade before committing to it rather than discovering it in the month-end report.
The reverse trap is just as common. Discounting to fill rooms lifts occupancy and the property looks busy, but each occupied room also carries variable cost — housekeeping, linen, amenities, utilities, commissions — that an empty room does not. RevPAR is a revenue measure and says nothing about those costs, so a RevPAR-positive discount can still be margin-negative. That is a profitability question, not an ADR question, and it needs a cost model this page does not attempt.
What ADR Excludes, and Why That Matters
ADR is rooms revenue per occupied room. It excludes food and beverage, meeting and banqueting revenue, spa, parking, and anything else booked outside the rooms line. That exclusion is deliberate and it is what makes ADR comparable across very different properties — but it also means ADR systematically understates what a guest is worth at a full-service resort compared with a limited-service property.
Two properties can report identical $165 ADR while one earns another $40 per occupied room across its restaurant and spa and the other earns nothing. Total revenue per available room is the figure that separates them, which is the reason it sits in the result grid here. Treatment of resort fees, destination fees and mandatory service charges is a genuine grey area: whether they land inside rooms revenue or outside it is an accounting policy decision, and moving them changes ADR without anything about the hotel changing. If you are comparing your ADR to anyone else's, confirm that both sides treat those charges the same way before drawing a conclusion.
Complimentary and house-use rooms are the other classic distortion. Whether they count as rooms sold changes both occupancy and ADR, in opposite directions. Pick a treatment, document it, and apply it consistently across every period you intend to compare.
How This Differs From the Other Property Tools Here
The live vacancy rate calculator covers occupancy for long-term residential rentals — units, days vacant, lost rent — and has no nightly rate in it at all. Hospitality occupancy is measured in room nights and resets every night, which is why it needs its own page. The rental yield calculator and the gross rent multiplier calculator value an asset from its rent; ADR and RevPAR measure trading performance, not value.
If you are working from RevPAR toward an asset question, the cap rate calculator takes net operating income rather than revenue, so you will need a cost model in between. And the rental property calculator is built around monthly leases rather than nightly stays. This page stops at the revenue line by design.
Choosing the Period, and the Traps in It
ADR calculated over a month blends weekday and weekend, group and transient, into a single figure that may not describe any actual night. That is fine for reporting and poor for decisions. A property whose weekends run at $240 and midweek at $120 has a blended ADR somewhere in between and a revenue problem that only appears when you split the period.
Day-of-week, segment and channel splits are where the useful signal lives. Run this calculator several times on subsets of the same month — weekends only, group only, one channel only — and the picture changes considerably. The arithmetic is identical; only the slice of data changes. Industry bodies such as the American Hotel & Lodging Association publish research and resources on how properties segment and report performance, and their material is a reasonable place to start on segmentation practice.
One more period trap: a partial month has fewer nights, so available room nights shrink. Compare a 28-day February with a 31-day March on RevPAR and the difference is partly calendar, not performance. ADR is immune to that, which is one of the few situations where ADR is the safer comparison.

- Counting reservations instead of room nights — a four-night booking is four rooms sold, and treating it as one inflates ADR fourfold.
- Leaving non-room revenue in the rooms line — resort fees and parking folded into rooms revenue overstate ADR without changing anything about the hotel.
- Quoting ADR growth as a performance win — if occupancy fell further than rate rose, RevPAR is down and the headline is misleading.
- Changing the treatment of out-of-order rooms mid-series — it moves occupancy and RevPAR while the property performs identically.
- Comparing RevPAR across months of different lengths — available room nights differ, so part of the gap is the calendar.

Frequently Asked Questions
Average daily rate is net rooms revenue divided by the number of rooms sold in the same period. It measures the average price achieved per occupied room and excludes food, beverage, spa, parking and every other non-room revenue stream.
ADR divides rooms revenue by rooms sold; RevPAR divides the same revenue by rooms available. RevPAR therefore reflects unsold rooms as well as the rate achieved, and equals ADR multiplied by occupancy exactly.
Yes, provided all three figures are calculated over the same period with the same definitions of rooms sold and rooms available. The identity follows algebraically because rooms sold cancels out. If it does not close on your numbers, one of the three inputs is measured differently from the others.
It depends on whether your accounting treats those fees as rooms revenue or as a separate revenue stream, which is a policy decision rather than a fixed rule. Moving them changes ADR without anything about the hotel changing, so confirm the treatment on both sides before comparing to another property.
If a complimentary or house-use room is counted as sold, it adds to rooms sold without adding revenue, which lowers ADR and raises occupancy. Excluding it does the reverse. Either treatment is defensible; changing between them mid-series is not.
It divides all revenue, rooms plus food and beverage and other departments, by available room nights. It is useful for comparing full-service properties against limited-service ones, and it is a different measure from ADR rather than a variant of it.
No, and deliberately so. Judging a rate requires market, class and season data for your specific competitive set, which comes from a benchmarking subscription. This tool publishes no market rates and takes any comparison figure as an input from you.
Whichever period you intend to act on. A monthly ADR blends weekday and weekend into a figure that may describe no actual night, so splitting by day of week, segment or channel usually reveals more than the blended number does.
This calculator applies published industry definitions to figures you supply. It contains no market data, no benchmark rates and no view on whether any result is good or bad. Revenue reporting policy, the treatment of fees and out-of-order rooms, and any commercial decision that follows are matters for your own accounting standards and your management team.
