Apple's first foldable iPhone ships with a four-tier price list, a storage ladder that quietly changes shape between countries, and several ownership costs the company has not published at all. This is a snapshot of what an iPhone Duo costs on paper right now — list prices in three currencies, the arithmetic of each storage step, trade-in eligibility, and the specific gaps in Apple's own numbers. If you are deciding which configuration to pre-order on 16 October, the decision is less about the phone than about which of these numbers apply to you.
This comparison is based on official documentation, published specifications, and vendor pricing verified as of 13 September 2026. Nothing here is a retail observation: Apple's announcement sets pre-orders for Friday 16 October and availability for Friday 23 October in more than 70 countries, with 28 more on 30 October. No unit has reached a buyer.
The published price list, in three storefronts
Apple published only the $1,999 entry price in its press release. The full ladder appears on the regional store pages, and it is now live in all three markets below.
| Capacity | United States | United Kingdom | South Korea |
|---|---|---|---|
| 256GB | $1,999 | £1,999 | ₩3,290,000 |
| 512GB | $2,199 | £2,199 | ₩3,590,000 |
| 1TB | $2,599 | £2,599 | ₩4,190,000 |
| 2TB | $3,199 | £3,199 | ₩5,090,000 |
The UK and US figures are digit-for-digit identical, which is a presentation coincidence rather than a price equivalence — US store prices exclude sales tax, and Apple's own iCloud+ pricing documentation confirms that the UK and Korea are tax-inclusive storefronts while some US states add tax on top. Converting £1,999 to dollars and declaring the UK more expensive is the error this table is meant to prevent.
The storage ladder keeps its shape but not its size
Every market uses the same incremental pattern: the second step costs twice the first, the third costs three times the first. What changes is how large that first step is relative to the phone. Expressing each step as a percentage of the local base price removes tax and exchange rates from the comparison entirely, because both cancel out in the ratio.
| Upgrade from 256GB | US / UK | South Korea |
|---|---|---|
| to 512GB | +10.0% of base | +9.1% of base |
| to 1TB | +30.0% of base | +27.4% of base |
| to 2TB | +60.0% of base | +54.7% of base |
A Korean buyer moving to the top tier pays a premium roughly five percentage points smaller than an American or British one. It is not a discount anyone advertises, and it is the sort of difference that only appears once the currencies are taken out of the picture. The same logic applies to the gap against the non-folding flagship: in the US the Duo sits $800 above the $1,199 iPhone 18 Pro, in Korea ₩1,300,000 above the ₩1,990,000 model.
Every storage step, priced in months of iCloud+
On-device storage and cloud storage are not interchangeable — local capacity works offline and holds installed apps and games, which iCloud+ does not. But both are ways of solving "I have run out of room," and Apple sells them side by side, so the exchange rate between them is worth knowing. Dividing each storage step by the monthly iCloud+ price in the same market gives the number of months that money would otherwise buy.
| Storage step | Compared against | US | UK | Korea |
|---|---|---|---|---|
| 256GB → 512GB | 200GB iCloud+ | 67 months | 67 months | 68 months |
| 256GB → 1TB | 2TB iCloud+ | 60 months | 67 months | 64 months |
| 256GB → 2TB | 2TB iCloud+ | 120 months | 133 months | 129 months |
The 2TB row is the one that should change behaviour. In every market, the money that separates a 256GB Duo from a 2TB Duo would pay for a decade or more of Apple's largest consumer cloud tier — and that tier holds 2TB regardless of which phone you attach to it. Buyers who stream rather than download, and who are not carrying large offline game installs, are paying a ten-year subscription up front for capacity most of them will not fill.
The 512GB row is the opposite case and the more defensible upgrade. Five and a half years of a 200GB plan is a real cost, and 200GB of cloud does not help when an app needs space on the device itself.
How much of each tier you actually get
Apple's store footnote states that a standard configuration consumes roughly 12GB to 24GB, and that on-device Apple Intelligence models take about 7GB more. Nobody subtracts this when comparing tiers, but the same fixed overhead lands very differently depending on where you start.
| Nominal capacity | System and model overhead, as a share of the tier |
|---|---|
| 256GB | 4.7% – 12.1% |
| 512GB | 2.3% – 6.1% |
| 1TB | 1.2% – 3.0% |
| 2TB | 0.6% – 1.5% |
On a worst-case 256GB unit with Apple Intelligence enabled, close to an eighth of the advertised capacity is gone before a single photo is taken. One thing that genuinely cannot be calculated from official sources: Apple publishes no bitrate for the Duo's 4K120 Dolby Vision recording, so any "hours of video per tier" figure you encounter is an outside estimate, not an Apple number. Anyone weighing tiers on video capacity is working without a published denominator. For a sense of how the A20 Pro powering this recording compares with the previous generation, our flagship chipset comparison covers the A19 Pro baseline Apple measures against.
Trade-in: the ceiling gets the headline, the floor decides eligibility
Apple advertises trade-in as a range, and the top of that range needs a recent flagship in good condition. The more useful number is the bottom — the oldest device that qualifies at all — and that differs by market in a way the headline figures hide.
| Market | Published credit range | Oldest eligible device |
|---|---|---|
| United States | $35 – $885 | iPhone 8 Plus or newer |
| United Kingdom | £25 – £855 | iPhone SE (2nd generation) or newer |
| South Korea | ₩50,000 – ₩1,670,000 | iPhone X or newer |
Three storefronts, three different eligibility baselines spanning roughly three device generations. Apple does not publish a per-model value table in any of them, so the only way to find your actual figure is to run the estimator before ordering.
Financing: the same phone, three different bills
The US store lists $83.29 per month over 24 months for the 256GB model, which totals $1,998.96 — interest-free, and the same money as buying outright. The UK store spreads the identical £1,999 over 30 months at £66.63, totalling £1,998.90. Same phone, same digits, six extra months of payments. Comparing the monthly figures across borders tells you nothing without the term length attached.
Apple Upgrade, the US leasing option, starts at $57.99 per month over 24 months — $1,391.76 in total, after which the device goes back. That is roughly 70% of the purchase price for two years of use with no residual asset, and Apple has not published what the end-of-term buyout costs. There is also a small absence worth noting: the Duo is priced identically for AT&T, T-Mobile, Verizon and unlocked, whereas Apple's own footnote discloses a $30 connectivity discount baked into the iPhone 17's advertised price. No such discount applies here.
What the $1,999 does not include
The box holds the phone and a one-metre USB-C cable. Apple's fastest published wired figure — 50% in around 20 minutes — is measured with its 40W Dynamic Power Adapter, sold separately at $39. The iPhone Duo Case is $79 and the Folio with kickstand is $129 in the US; Korea prices them at ₩119,000 and ₩199,000, which is marginally cheaper as a share of the local phone price.
Then there is the category of things Apple confirms exist but has not priced. AppleCare+ is stated to be available for the Duo, yet no per-device monthly or annual figure appears anywhere; the only published protection prices for this launch are AppleCare One at $19.99 per month for up to three devices and AppleCare One Family at $49.99. No repair price has been published for the folding display, the hinge, or the battery. Apple Pencil support is confirmed but dated only to later in 2026, with no price attached. A realistic budget for this phone therefore has a floor and no ceiling, which is an unusual position for a product this expensive and a fair reason to wait for the October pricing pages before committing. Readers who followed how quietly the handheld console market repriced itself this year will recognise the pattern from our handheld pricing breakdown.
Which configuration fits which buyer
- 256GB, $1,999. Cloud-first libraries, streaming rather than downloading, no large offline game installs. Accept that up to an eighth of the tier is system overhead, and budget an iCloud+ plan alongside it.
- 512GB, $2,199. The step with the best arithmetic. It costs about 10% of the base price and buys more than five years' worth of a 200GB cloud plan, while also solving the on-device app and game problem that cloud storage cannot.
- 1TB, $2,599. Justifiable if you record 4K120 regularly and keep footage on the device before offloading. In Korea this step buys fewer months of equivalent cloud storage than in the US or UK, so it clears the bar there more easily.
- 2TB, $3,199. Hard to defend on published numbers alone. The premium over base equals a decade of 2TB iCloud+ in every market checked, and the overhead advantage over 1TB is under two percentage points.
- Wait entirely. If accidental damage is a realistic risk for you, the two numbers that would let you price that risk — AppleCare+ for the Duo and any repair cost for a folding display — do not exist yet.
Frequently asked questions
Why are the US and UK prices the same number?
Apple set both ladders to the same digits, but they are not the same price. US store prices exclude sales tax while the UK storefront is tax-inclusive, so the comparison is not like-for-like and a currency conversion will mislead you.
Is the 2TB model ever worth it?
On published figures, rarely. The $1,200 premium over the 256GB model equals about ten years of Apple's 2TB iCloud+ tier at $9.99 per month. It makes sense only if you specifically need that capacity available offline.
How much does AppleCare+ cost for the iPhone Duo?
Apple has not published a per-device price. The only protection figures published for this launch are AppleCare One at $19.99 per month covering up to three devices, and AppleCare One Family at $49.99 per month.
Does the iPhone Duo come with a charger?
No. The box contains the phone and a one-metre USB-C cable. Apple's 50%-in-20-minutes figure is measured with a 60W-capable adapter, and its own 40W Dynamic Power Adapter is a separate $39 purchase.
Can I use a physical SIM?
No. The iPhone Duo is eSIM-only worldwide and has no SIM tray, which matters if you rely on local prepaid SIMs in markets where eSIM support is patchy.
