Why does the exchange rate change what Cowork costs?

Copilot Credits are priced in US dollars - $0.01 each on pay-as-you-go - and billed through Azure. A UK business pays in pounds, so the cost of a fixed amount of usage rises and falls with the exchange rate. This site deliberately converts at a cautious £1 = $1.27, below every rate seen in 2026 ($1.31 to $1.39), so its pound figures carry a small buffer. At October 2026's rate of about $1.32, the same usage costs roughly 4% less than we show.

For most businesses this is a rounding error on a modest bill. For a 30-desk business spending £3,500 a month on usage, a 5% currency move is £175 a month - noticeable on a budget line, not a crisis. The licence line doesn't move; Microsoft sets UK licence prices in pounds and changes them rarely.

Two ways to handle it. Budget the usage line with a buffer and forget about it - this is the sensible default, and it's exactly what this site's cautious rate does for you. Or, if usage is large and predictable, the pre-purchase plan fixes a year's credits at a known dollar amount, which you can convert once; that removes the month-to-month wobble, though not the dollar exposure itself.

If you want a sharper figure for today, the credits-to-pounds converter lets you type the current rate. We review the site's rate monthly, and keep it below the market on purpose.
