Three things set what an iPhone costs: the tier a model sits in, the storage it ships with, and what its parts cost Apple. In this post's record the tier does the most work, because a new model added at the top moves the lineup further than any repricing of an existing one. Storage is the quieter lever: the 2025 iPhone 17 kept its $799 price and doubled base storage to 256GB. Parts are the newest pressure. The Wall Street Journal, citing TechInsights, estimated memory and storage chips at about $196 in an iPhone 18 Pro, against roughly $52 in an iPhone 17 Pro.
Look closely at the year-over-year record and a pattern emerges: it's new tiers at the top of the lineup, not steep repricing of the phones people already know, that do the real work. In 2017 the base and Plus tiers moved only modestly - iPhone 8 to $699, a $50 increase on the iPhone 7, and iPhone 8 Plus to $799, a $30 increase on the iPhone 7 Plus - while Apple introduced an entirely new tier above them: the iPhone X at $999, the first iPhone ever to cross the four-figure mark. That new $999 tier, not the modest bump on the base and Plus tiers, is what pulled the lineup's average sharply higher that year.
This is the mechanism in its clearest form: the biggest price move in a lineup rarely comes from repricing a phone that already exists - it comes from inserting a new tier above it. The base and Plus tiers absorbed only a small, incremental increase in 2017; the iPhone X's $999 debut is what actually dragged the lineup's average sharply upward that year. Anyone drawn to the new design, screen, or camera system paid a real premium for a genuinely new product - that premium, not a hike on the familiar models, is where most of the year's price growth actually happened.
The 2020 iPhone 12 generation is the exception that proves the rule: this is the one year the base tier itself was directly repriced, from $699 in 2019 to $799, a straightforward $100 increase rather than a new tier absorbing the difference. The Pro ($999) and Pro Max ($1,099) held at exactly what the iPhone 11 Pro and 11 Pro Max had already reached the year before - and that three-tier Base/Pro/Pro Max structure wasn't new in 2020 either; it dates back to the iPhone XS Max in 2018. What actually changed in 2020 was Apple finally moving the entry price after three years of the base tier drifting between $699 and $749. Tier creation is Apple's most-used lever, but 2020 shows the company will also move an existing sticker price directly when it decides to.
The ladder has kept growing since 2020. The iPhone Air arrived in September 2025 at $999, a new slim tier above the $799 iPhone 17 and $100 over the $899 Plus it replaced in this dataset. The iPhone 17e followed in March 2026 at $599 with 256GB of storage, a rung below the base model. On September 9, 2026, Apple unveiled iPhone Duo, its first foldable, at $1,999, far above the iPhone 18 Pro Max's $1,299. Each one added a tier instead of nudging the price of an existing phone.
Memory and storage chips are why that ladder is getting steeper. On Apple's July 30, 2026 earnings call, Tim Cook said the company was in "a 100-year flood on memory pricing" and had "reluctantly raised prices" on Macs and iPads. Six weeks later, on launch day, Apple raised the online-store prices of the iPhone 16, iPhone 17, iPhone Air and iPhone 17e by $100 each, as MacRumors reported, while pricing the iPhone 18 Pro at $1,199 and the Pro Max at $1,299, each $100 above its predecessor. Where Apple sets the price, it still decides by tier; where it does not, the pressure comes from memory and storage chips.
