The 2026 Hidden Running-Cost Index: What 41 Popular Devices Really Cost Over 3 Years
The price on the box is only the down payment. Many devices now come with plans, and some stop doing the thing you bought them for without one. Others quietly eat filters, pads, bags or ink. We priced 41 popular devices, and what it costs to keep each one running for three years, directly from each maker's own US store.

devices cost at least twice their sticker price over three years of typical use

the biggest gap: the Canon PIXMA TR4720 ($108 sticker, $705 over three years)
$300
median three-year spend on top of the sticker price, among devices with any recurring cost

How we calculated it
Sticker price is the maker's US list price in September 2026 (or typical street price where the maker doesn't sell direct, noted per device in the sources).
Per year adds every recurring cost: subscriptions at their published annual (or 12× monthly) price, and consumables at the maker's own recommended replacement interval, priced from the maker's store.
3-year cost is the sticker price plus three years of what a typical owner pays: any plan required for the core feature, the plan the maker presents as the default, and consumables. A strict minimum (sticker plus required plans only) is in the downloadable data.
We use regular list prices, not today's sale, and we don't subtract free trials or a first year included with the device (where one applies, the three-year figure is one year of the plan too high). Taxes, shipping, electricity and repairs are not included. Where a maker no longer sells a model, we priced its current replacement and say so in the sources. Prices change; each device lists the date its prices were checked. This is research from published prices, not a hands-on test.
