In short: The device lab cost calculator compares 12 months of a cloud device farm with a lab of your own Android phones. Enter your phones, their hours of use and what new phones would cost; vendors' list prices checked on 23 October 2026 and BenchFleet Pro at £12 a month + VAT are prefilled, every formula is shown, and nothing leaves your browser.
Over 12 months, in pounds at 0.748 pounds per dollar. List prices before tax and discounts.
Rented devices in a cloud
The page also offers a one-time 1,000 free device minutes, left out here.
The page says "per slot per month": one slot is one device at a time, counted here as one per phone.
From 1 parallel. The page does not show how the price changes with more parallels ("lower price per parallel with higher volume"), so the formula multiplies by parallels. The App Automate prices (native apps) could not be read on the page that day and are not used.
The page offers 1 to 5 concurrent sessions and does not say how the price changes with more, so the formula multiplies by parallels. Annual plans are charged up front.
The page offers 1 to 5 concurrent sessions and does not say how the price changes with more, so the formula multiplies by parallels.
Parallel options from 1 to 5+. The page shows no price per added parallel, so the formula multiplies by parallels.
Your own phones
Runs on devices you own: the first device is free, then $99 per device per month. The phones are yours to buy.
A flat plan price: it does not change with how long the phones are used. VAT is extra where it applies and is not added here.
A cloud's price includes the devices and their upkeep, which with your own phones you buy and look after yourself, and clouds offer iPhones and many models you may not own.
Cloud prices checked on 23 October 2026 on each vendor's own page; they change, so check before you buy. We make BenchFleet. The defaults are the 12-month example from the guide to a self-hosted device lab against a device cloud: 5 phones used about an hour each working day, with phones you already have. Change any number to match your lab.
Free for up to 3 phones, with no account. Pro adds workflows, schedules and AI for up to 25 phones from £12 a month + VAT.
Every total is a list price multiplied by the numbers you enter. Nothing else is added.
List prices in US dollars, before tax and discounts, each checked on the vendor's own page on 23 October 2026.

Firebase Test Lab is not in the table: its price per device hour was not checked on Google's own page on 23 October 2026, and Google shuts the service down on 30 September 2027. See the Firebase Test Lab alternative for what to move to, and the Firebase Test Lab migration page for a calculator of Test Lab usage.
For the cloud side in more detail, see the BrowserStack alternative, the Sauce Labs alternative and the AWS Device Farm alternative.
Each cloud price was checked on the vendor's own pricing page on 23 October 2026 and is linked in the table on this page. BenchFleet's prices come from the same plan catalogue the app and checkout use. Prices change, so check before you buy, or type in a quote you were given.
Zero means phones you already have. Type what one phone you would buy costs, in dollars or pounds, and the calculator adds phones × that price to the options that run on your own phones. A cloud's price already includes its devices.
Prices per parallel are multiplied by the parallels you enter, one per phone unless you change it. The vendors' pages do not say how the price changes with more parallels, and some mention volume prices, so treat that total as a list-price estimate and ask the vendor for a quote.
No. BenchFleet's prices, Pro at £12 a month + VAT and Team at £20 per seat a month + VAT, are without VAT, which is added where it applies. The cloud prices are list prices before tax, as their pages show them. The calculator adds no tax to any option.
No. It runs in your browser and sends and stores nothing. The exchange rate is the ECB reference rate written into the page, not fetched, and you can change it to today's rate or your bank's.
Free for up to 3 phones, with no account. Pro adds workflows, schedules and AI for up to 25 phones from £12 a month + VAT.
