Is there an average CPM for Facebook ads in Turkey I can plan a budget around?

Not one that stays true long enough to plan with. Any lira average carries an exchange rate embedded in it from the date it was measured, so it drifts even when the auction does not move at all. Plan from your own account's recent spend converted at a stated rate, and treat any published figure as a rough starting orientation you replace with your own data as soon as you have a few weeks of it.

Should I open my Turkish ad account in lira or in dollars?

It depends on which currency your revenue and your reporting sit in. A lira account matches local revenue and makes ratios like ROAS clean, while a dollar or euro account matches head office reporting and makes the P&L clean. Whichever you pick, the account currency is not something you can casually change afterwards, so confirm the current rules in Meta's official documentation before creating the account.

My CPM rose 30% in lira. Does that mean competition is increasing?

Not until you divide it out. Convert the CPM at each period's own exchange rate and compare the converted figures. If the lira price of a dollar rose 20% over the same window, a 30% lira rise is roughly 1.30 divided by 1.20, so about 8% in dollar terms. If the rate was flat, the whole 30% is genuine auction pressure and deserves a response.

Do global benchmark tables apply to advertising in Turkey?

Use them as orientation, never as targets. Most public benchmark tables are built from accounts in other markets and other currencies, with sample sizes and definitions the report itself usually discloses somewhere. Read the methodology note before you read the numbers, and check whether the report breaks out Turkey or EMEA at all before treating any row in it as your goal.

Does a weaker lira mean cheaper advertising for a foreign company entering Turkey?

In your home currency the cost of buying impressions can fall, which is the part most entrants notice. The part they miss is that local purchasing power moves too, which affects conversion rates and order values in the same market. Judge entry on the ratio between what you pay and what a customer is worth in one consistent currency, not on the impression price alone.

Facebook Ads Cost in Turkey: Read It in Ratios

There is no single number that answers what Facebook ads cost in Turkey, and any page that hands you one in lira is quietly hiding how fast that figure expires. Two independent things move underneath a quoted cost in this market: the auction, which is advertiser demand for the same audience, and the exchange rate, which changes what a lira bid is worth without anyone bidding differently. A figure that bundles both together cannot be acted on, because you cannot tell which half moved.

Why a lira figure for Facebook ads cost in Turkey ages faster than the article it sits in

When someone publishes a CPM for this market, that number was true for a particular set of campaigns, in a particular month, against a particular level of competition, at a particular exchange rate. The first three you can reason about. The fourth silently rescales every lira figure ever published about the market, including the one you are reading.

This is why cost tables age differently depending on the currency they are denominated in. A dollar CPC table from a stable-currency market two years ago is at least roughly comparable to today. A lira cost table from two years ago is comparable to nothing at all unless you also know the rate on both dates and are willing to do the conversion yourself. Most readers do not, so the number gets copied forward and quoted as if it were current.

The practical consequence: stop looking for the right number and start reading cost in relative terms, as a ratio to something that moves alongside it.

Splitting a cost rise into the currency part and the auction part

Take a made up but arithmetically clean case. Your account averaged a CPM of 100 lira in one quarter and 132 lira two quarters later. In lira, that is a rise of 32%, because 132 divided by 100 is 1.32.

Now suppose that over exactly the same window, the lira price of one dollar in your own billing records went from 30 to 36. That is a rise of 20%, because 36 divided by 30 is 1.20.

Convert both CPMs at their own dates. 100 divided by 30 is about 3.33 dollars. 132 divided by 36 is about 3.67 dollars. The ratio between them is 1.32 divided by 1.20, which is exactly 1.10. So the cost of reaching a thousand people rose 10% in dollar terms while the headline lira figure rose 32%. Most of what looked like an auction getting more expensive was the currency.

The same arithmetic protects you in the other direction. Had the rate been flat across those two quarters, the entire 32% would be real auction pressure, and writing it off as a currency artefact would mean ignoring a genuine competitive shift. You cannot know until you divide.

The lira falling 20% and the dollar rising 20% are not the same sentence

This trips up more reports than it should. If the lira price of a dollar goes from 30 to 36, the dollar rose 20%. The lira did not fall 20%. A lira was worth one thirtieth of a dollar and is now worth one thirty sixth, so 0.0278 divided by 0.0333 is about 0.833, a fall of roughly 16.7%. Two correct numbers describing one event, and they are not interchangeable. Pick one direction, state it in the sentence, and hold it for the whole report.

Your account currency decides which of the two clocks you can see

An ad account bills in the currency it was set up with, and platforms generally treat that as a fixed property of the account rather than a setting you flip later. Confirm the current rule in Meta's official documentation before you open the account, not after, because billing thresholds, time zone and currency behaviour are exactly the sort of thing platforms revise.

The choice matters more than it looks. A lira account produces numbers that line up with your local revenue and completely hide the exchange rate movement. A dollar or euro account produces numbers your head office can read straight into the P&L and hides the local auction movement instead. Neither is wrong. What causes damage is forgetting which clock you chose and then reading a trend line as if it were the other one.

One habit regardless of the choice: when your bank converts, the dashboard total and the amount that leaves your account are not the same figure. Reconcile against the billing statement for the period before you calculate anything downstream from spend.

Cost only means something next to what a customer is worth

CPM and CPC are input prices, and an input price on its own cannot be judged good or bad. Whether they are the right unit to be watching at all is a separate question worth settling first, and the differences between CPA, CPC and CPM decide which of them your decisions should hang on.

The measures that survive a currency move are the ones where the numerator and the denominator are denominated in the same currency. ROAS is revenue over spend. MER is total revenue over total spend. Cost per acquisition divided by average order value is the same idea expressed per customer. If both sides of the ratio are in lira, a 20% move in the lira price of a dollar cancels out of the ratio entirely and you are left looking at performance rather than at foreign exchange. That, not tidiness, is the real reason to steer this market on ratios.

There is one condition on that cancellation, and many Turkish accounts may fail it when costs are tied to foreign currency.

The case where your ceiling moves and your cost does not

Ratios stay currency neutral only while your cost base sits in the same currency as your revenue. For an importer, a chunk of it does not.

Say your average order value is 1,000 lira. Cost of goods is 600 lira, split into 200 lira of local cost and 400 lira of imported goods priced in dollars. Contribution before advertising is 1,000 minus 600, so 400 lira, a margin of 40%. Break even ROAS is 1 divided by 0.40, which is 2.5.

Apply the same 20% move in the lira price of a dollar used earlier. The imported component becomes 400 times 1.20, so 480 lira. If your shelf price stays at 1,000, cost of goods is now 200 plus 480, so 680 lira. Contribution falls to 320 lira and the margin to 32%. Break even ROAS becomes 1 divided by 0.32, which is 3.125, or about 3.13. Check it the other way: 3.125 times 0.32 returns 1.00.

Nothing on Meta changed. Your CPM, your CPC and your delivered ROAS are all exactly what they were. What moved is the ROAS you need, from 2.5 to about 3.13, which is 25% higher. An advertiser watching cost sees a calm quarter. An advertiser watching the gap between cost and margin sees a ceiling that just dropped onto their head. Recompute yours whenever the rate moves materially, using a break even ROAS calculator rather than the figure you wrote down last year.

An operating rule for reporting cost across two currencies

Fix one currency per analysis and put it in the report title, so nobody has to guess which clock a chart is running on.
Quote cost as an index against your own trailing period rather than as an absolute, and state the window in the same breath.
Take the rate from your own billing records for those exact dates, not from a headline rate on the day you build the deck.
When head office reports in euros or dollars, publish two lines, the local one for campaign decisions and the reporting one for the P&L, and say plainly which one you are steering on.
Never place a lira CPM next to a global or US sector table without converting first. Those tables are orientation, not targets.
Re check break even ROAS on a schedule if any part of your cost base is imported.

This choice also decides what an automated system ends up optimising toward, so if you are evaluating automated budget scaling, settle the unit question before the rules go live rather than after a currency move gets logged as a performance problem.

Building a rolling baseline from your own account is the other half of this work and deserves its own treatment. The short version is that your own trailing periods, measured in one currency and set against the same weeks a year earlier, will beat any published table, because they are the only figures denominated in the currency you actually pay in.
