Apple Ads cost: CPT bids, budgets and the CPI math

How does Apple Ads decide what you pay?

You pay per tap, and the max CPT bid you set is a ceiling, not a price. Apple's bidding guide says the max CPT bid "is the most you'll ever pay for a tap — many times you'll pay less."

Whether your ad shows depends on two things together: how relevant your app is to the search, and your bid. Apple is explicit that money cannot buy relevance: if your app does not match what the person searched for, it is not shown "regardless of how much you may be willing to pay". You also cannot choose or bid for a particular ad position.

Bids live at two levels. The default max CPT bid on an ad group applies to every keyword in it; a bid you set on one keyword overrides that default for that keyword only. New keywords added later still get the ad group default.

Apple Ads Basic works differently: you pay per install, up to a max CPI that Apple suggests or you set, and the budget is monthly (up to 10,000 USD per app).

How does the daily budget work?

The daily budget is the average you want to spend per day over a month, not a hard daily stop. Apple caps the month instead: a campaign's monthly spend won't be more than daily budget × 30.4, the average number of days in a calendar month. On days with more opportunity, spend can go over the daily figure.

The campaign keeps spending every month until you pause it, remove it or reach its end date. With an end date, it won't spend more than its number of days × the daily budget.

Which metrics turn a tap into a cost per install?

Apple's reports use these definitions (from the Apple Ads glossary):

• Average CPT: spend ÷ taps.
• TTR (tap-through rate): taps ÷ impressions.
• CR (tap-through): installs from ad taps ÷ taps.
• Average CPA (tap-through): spend ÷ installs from ad taps. This is your cost per install from taps.
• ROAS: revenue ÷ ad cost × 100.

Installs count as tap-through when they happen within 30 days of the tap; view-through installs (seen, not tapped) are counted within one day of the view. Both new downloads and redownloads are included unless you look at those columns separately.

The link that matters: CPA = average CPT ÷ CR. A page that converts twice as well halves your cost per install at the same bid.

A worked example

The numbers below are invented to show the arithmetic. They are not benchmarks, averages or expectations for any country or category.

A habit tracker called Stepwise runs one category campaign for 30 days:

At 80% ROAS the campaign returns 0.80 for every 1.00 spent within that window. Whether that is acceptable depends on how much those users pay after the window, which only your own data can tell.

How do you work out the CPT you can afford?

Start from what an install is worth to you, not from someone else's average.

1. Value per install. Revenue from a group of users over a fixed window (for example 30 or 90 days), divided by the number of users. Use organic users first if you have no paid ones yet.
2. Target CPA. The most you will pay per install. Set it below value per install if the campaign must pay back inside the window.
3. Affordable average CPT = target CPA × CR. With an invented target CPA of 4.00 and a 40% CR, you can afford an average of 1.60 per tap.
4. Max CPT. Because you often pay less than your max, the max CPT bid can sit above the affordable average; start near Apple's suggested bid, then let the CPA tell you where to move it.

For Maximize Conversions campaigns, the target CPA is the input itself: Apple's auto-bidder aims for it on average, so a single day can be over or under. Apple recommends waiting at least two weeks before changing it, and using the daily budget if you want to control total spend.

Why is there no "average CPT" for your country?

Apple does not publish average CPT or CPI figures by country, category or keyword, and a single average would mislead you anyway. Each search term has its own auction, with its own advertisers and its own relevance to your app. Your CR depends on your product page, your ratings and the term's intent. Two apps bidding on the same word can end up with very different costs per install.

What Apple does give you is your own context:

• a suggested max CPT when you create an ad group, based on what Apple knows about your app and what advertisers with similar apps are willing to pay;
• recommended bids in the Max CPT Bid column on the All Keywords dashboard;
• the Recommendations page, with impression share, rank, search popularity, installs, spend, average CPA and CPT, and estimates of installs, spend and average CPA.

The most reliable estimate is a small test: a few exact match keywords per theme, a budget you accept losing, and one to two weeks of data before you judge.

When should you raise or lower a bid?

Apple's help lists the scenarios:

Apple also recommends a tiered setup: the most aggressive bids on important exact match keywords, strong bids on similar broad match keywords, and more moderate bids on Search Match discovery. In the bidding guide's words: "For optimal performance, most of your traffic should come from exact match." Keep broad and exact keywords in separate ad groups or campaigns so each tier has its own bid. The four-campaign template behind this is in Apple Ads campaign structure.

Seasons matter too: Apple suggests adjusting bids on existing keywords, or adding new keywords with stronger bids, around seasonal peaks.

Where does Uptika fit?

Uptika does not set your bids and has no budget calculator; the arithmetic above is meant for your own spreadsheet. On paid plans, after you connect your Apple Ads account, Uptika's Performance page shows spend, taps, installs, CPT and CPA against the previous period, and Opportunities flags keywords far above your target cost and terms that spend without installs. Ads and search rank shows, per keyword, your organic rank next to the paid results, so you can see where you already rank well organically before raising a bid. Any change needs your confirmation. Setup steps are in Apple Ads setup; check keyword popularity first in the free Keyword Atlas, or create an account.
