Real ADR: has your room rate risen, or only inflation?

Real ADR is your average daily rate restated in the money of a chosen base period, calculated by dividing nominal ADR by a price index and multiplying by 100. It answers whether the room earned more purchasing power than before. A lira ADR that rises more slowly than the index has fallen in real terms.

The owner asks one question: did the room earn more this year? The spreadsheet answers with a lira figure that is larger than last year's, and that figure cannot answer the question on its own, because the lira it is measured in is not the same lira. After reading this you will be able to compute a real ADR inflation adjusted from your own numbers, state an ADR in euro under a rule you can defend, and put all three on one page for the owner.

What is real ADR, and why can a rising lira rate be a fall?#

Real ADR is nominal ADR divided by a price index and multiplied by 100, which restates the rate in the money of the index's base period. A lira ADR that grows more slowly than the index has lost purchasing power, even though the number on the invoice went up.

Start with ADR itself, defined plainly: room revenue divided by rooms sold. Sold rooms, not available rooms. Fix both halves of that definition before comparing any two months, because a change in what counts as room revenue, or in which rooms count as sold, will quietly contaminate the comparison.

The three versions answer three different questions. Nominal lira ADR answers what the guest paid. Real lira ADR answers what the hotel can buy with it. Euro ADR answers what a buyer who thinks in euro sees. The lira number misleads because the unit changed: a larger number can buy less. That is the whole mechanism, and it needs no theory beyond that.

Deflating ADR is legitimate because ADR is already a price per room-night. Deflating total room revenue is a different operation, because revenue also carries volume and mix, and a deflator cannot separate those. Keep the deflator on the price, and handle volume separately.

One warning before you call anything a price increase: a rise in ADR can come from mix rather than price. More suites sold, fewer discounted channels, fewer group rooms. Check rooms sold by room type before describing the movement as a rate change.

Decide which version leads your reporting. Market-facing pricing conversations use nominal. Owner and investor conversations use real. Contracts with foreign counterparties use euro.

Three ADRs for one hotel: a worked example#

One month of one hotel produces three different ADR figures from the same room revenue, and each is correct for its own question.

For example, a hotel sells 2,400 room-nights in the month and records 4,800,000 lira of room revenue, so nominal ADR is 2,000 lira. In the same month last year ADR was 1,500 lira, so the nominal change is about +33 percent.

For the real figure, suppose the index for this month is 160.0 and for the same month last year 125.0 on the same base. Real ADR is 2,000 × 100 ÷ 160 = 1,250, against 1,500 × 100 ÷ 125 = 1,200 last year. That is a real gain of about +4 percent.

For the euro figure, suppose the written rule is the TCMB indicative rate on the last business day of the month: 40.00 this year and 34.00 last year. Euro ADR is 50.0 against 44.1, about +13 percent.

Illustrative example; all numbers are invented.

Read the three together: nominal +33, real +4, euro +13. All three are true, and each tells the owner something the other two cannot. These figures are invented for illustration and must be replaced with the hotel's own numbers before any decision.

Before trusting the comparison, check the comparability condition: same rooms-sold definition, same room mix, same revenue scope, meaning whether breakfast or other inclusions sit inside room revenue, in both months. Otherwise part of the change is mix, not price.

How do you deflate a lira ADR with TÜİK's consumer price index?#

Divide the month's nominal ADR by that month's index number and multiply by 100; the result is ADR expressed in the purchasing power of the index base period.

Step one: take ADR from your own system for the month, on the fixed definition you wrote down. Step two: take the index number for the same month from TÜİK's monthly bulletin. TÜİK publishes the consumer price index monthly on a 2025=100 base (opens in a new tab) and gives the change against the previous month, against December of the previous year, against the same month of the previous year, and against twelve-month averages (TÜİK, Tüketici Fiyat Endeksi, Ekim 2026, 3 November 2026).

Step three: real ADR = nominal ADR × 100 ÷ index. Step four: repeat for the comparison month, then compare two real figures with each other. Never compare one real figure with one nominal figure.

Step five, if you prefer to work with growth rates: real change = (1 + nominal change) ÷ (1 + index change) − 1. In the example above, 1.333 ÷ 1.280 − 1 gives about +4 percent.

Choose one of the four published change measures and keep it. The same-month change matches the season and suits a year-on-year comparison; the twelve-month average smooths one-off moves but lags them. On timing, the October 2026 bulletin was published on 3 November 2026 at 10:00, and TÜİK states the next one is due on 3 December 2026, so a monthly report can be closed within days of the index appearing.

Which index should you use: general TÜFE or the accommodation services index?#

Use the general consumer price index when the question is what the hotel can buy, and the accommodation services index when the question is whether your price moved faster than lodging prices generally. Name the index you used and do not switch mid-series.

The general index tracks a broad household basket. It is the better deflator for an owner's purchasing-power question, because it is the closest public stand-in for the money the hotel spends and the owner withdraws.

The accommodation services index follows lodging prices. Deflating your own ADR with it asks a narrower question: did we move ahead of the market's own price movement, which is not the same as beating inflation. Both come from the same statistical family, so the difference is not accuracy but meaning. Pick the one that matches the sentence you intend to write. If you want the detail of what the accommodation index does and does not measure, read what the accommodation index in Türkiye's inflation data measures before choosing it.

Record the index name, the base period and the bulletin date at the top of every report, so a reader six months later knows what the number means.

How do you state ADR in euro without picking a rate that flatters the answer?#

Write one conversion rule before the year starts, apply it to every month, and print it beside the figure. Which reasonable rule you choose matters far less than applying it without exception.

The Central Bank of the Republic of Türkiye sets indicative rates every business day (opens in a new tab) and posts them at 15:30 the same day, publishing them in the Official Gazette the following day. No rates are set on weekends, public holidays or half working days, and the rates bind no person or institution, since parties to a transaction choose their own rate (TCMB, Indicative Exchange Rates, 7 November 2026).

Three rules survive scrutiny. Rule one: the indicative rate on the last business day of the month, easy to defend and easy to reproduce. Rule two: the average of the daily indicative rates across the month, smoother but more work, and better for volatile months. Rule three: a fixed budget rate set once for the year, good for planning but wrong for year-on-year comparison, so label it as a planning rate.

Avoid the rate on the day the report is written. It moves with the reporting date rather than with the month being reported, and it invites the accusation that the rate was chosen after the result was known.

Convert ADR, not total revenue. Euro revenue mixes price with volume and channel mix, so it cannot isolate the price question. Keep the euro figure and the lira figure built from the same room revenue and the same rooms sold, so the only difference between them is the rate. For the pricing side of this question, see pricing hotel rooms in lira when costs are in lira.

Does real ADR growth cover your cost growth?#

Only if the deflated rate grows faster than deflated cost per occupied room. A real ADR gain and a real margin loss can appear in the same month.

Build cost per occupied room from your own profit and loss statement: total operating cost for the month divided by rooms sold. Use the same rooms-sold figure that produced ADR. Deflate both series with the same index and the same base, then compare growth rates, not levels, because levels from different deflators cannot be subtracted from each other.

Treat the consumer price index as a rough stand-in for a hotel's cost base. Wages, energy, food and the lira price of imported items move differently from a household basket, so use your own cost lines wherever you have them.

Look at flow-through as well: the share of each extra lira of revenue that reaches gross operating profit. A real ADR gain that never reaches profit is a gain on paper. Do not conclude "raise prices" from one month: a real fall can be a mix effect, a deliberate discount policy, or a market-wide move you did not cause. For the underlying mechanics, see GOP margin and flow-through calculated from your own P&L.

Illustrative structure with invented numbers; replace with your own P&L lines.

What should the owner see each month?#

One page carrying the three ADRs, the index with its bulletin date, the exchange-rate rule, and the real cost comparison, all on exactly the definitions used last month.

Start with a fixed definitions block at the top: what counts as room revenue, what counts as a sold room, which index and base period, which exchange-rate rule. Add the index bulletin date and the next publication date, so the reader knows how fresh the deflator is.

Show a rolling twelve months of real ADR rather than a single month, because seasonality and mix swing individual months hard. Show variance against budget in both nominal and real terms, on the same page, so the two are never quoted separately. For the variance itself, see reading the monthly budget-versus-actual variance in a hotel.

End with one short commentary line: what moved and why, naming mix, channel or discount policy. No adjectives. And keep an archive: a monthly series whose definition changed halfway is worth nothing, so save each page as issued.

What to do next#

Pick your definitions this week, then rebuild last month's ADR three ways and put the index name, its bulletin date and the exchange-rate rule at the top of the page. The three figures only become useful together: nominal tells you what the guest paid, real tells you what the hotel can buy, euro tells you what a foreign counterparty sees, and the cost comparison in real terms tells you whether any of it reached profit.
