How break-even CPT protects profit

The three-link chain#

Four definitions run every bidding decision. CPT is spend divided by taps, conversion rate is installs divided by taps, and CPA is CPT divided by conversion rate, while tap through rate (taps divided by views) diagnoses relevance upstream. When CPA runs hot, the chain tells you which link broke: auction price, product page, or ad fit.

AppTweak benchmarks (estimated vendor data, built from roughly 3,500 apps and $1B in spend) put the global search results medians near $0.92 CPT with a mid fifties conversion rate, and the US near $1.91. Read their Apple Ads benchmarks as distributions, not targets. Place the chain in context with the Apple Ads hub and the shared vocabulary in our TTR and CPT glossary.

Break-even CPT in one line#

Multiply revenue per install by your conversion rate and the answer is the highest CPT that still breaks even. A subscription app earning $4.00 per install at a 60 per cent tap-to-install rate breaks even at $2.40 per tap, before any return target. Divide again by your target return and you hold the profit-safe ceiling.

Revenue per install must be honest: trial starts that cancel, refunded purchases and lapsed subscribers all dilute it. Value each install through conversion values before trusting the line, and keep the ceiling written down where whoever edits bids can see it.

A worked example#

Take a finance app in the US. SplitMetrics 2025 panel data (estimated vendor data) reports search CPT near $2.25 with CPA near $3.76, tap through near 9.7 per cent and conversion near 66.2 per cent. Read their Apple Search Ads cost study for the panel behind the figures.

Now the maths: at 66 per cent conversion, a $2.25 CPT yields about $3.41 CPA, inside the panel CPA. If your revenue per install is $5.00, break-even CPT is $3.30, so the panel price leaves headroom; at $3.00 revenue it is $1.98, and the panel price loses money. Max CPT ceilings turn that verdict into bids, and US and UK benchmarks sharpen the yardstick by market.

Conversion rate is a bid multiplier#

Every point of conversion rate raises the CPT you can afford. At a $4.00 allowable CPA, a 50 per cent conversion rate supports $2.00 CPT, while 65 per cent supports $2.60: same economics, 30 per cent more bidding power, earned on the product page rather than in the auction.

That makes screenshots, previews and ratings part of bidding strategy. Tune the listing through screenshots and app previews, align each term with a fitting page via custom product pages, and reprice bids only after the page work lands.

Category baselines worth knowing#

US category medians from AppTweak (estimated vendor data) set expectations before you spend: Games near $4.21, Finance near $3.55, Shopping near $2.05, Education near $2.06, Health and Fitness near $1.59 and Productivity near $1.55. A games bid that looks reckless in utilities is simply the market clearing where it clears.

Judge your CPT against your own category and market, never against a global average. Split brand from generic before comparing, because blended figures hide leaks; brand, category and competitor terms shows the split, and discovery versus brand structure keeps the campaigns honest.

From maths to live bids#

Set each max CPT below its break-even ceiling, guard the ad group with a CPA cap near your allowable CPA, and let volume prove the maths before scaling budgets. Bids express the economics; they never repair them.

Wire the ceiling into CPA caps, fund enough days of learning through learning budgets, and if the numbers argue with your instincts, ask our team for a second read before raising anything.
