Microsoft has revealed that titles downloaded from Xbox Live's new games-on-demand channel will cost between 1600 and 2400 Microsoft Points.
In real money that equates to between £13.60 / €19.20 and £20.40 / €28.80.
Those prices were confirmed to Joystiq, a US website, but the MSP values should remain the same across all Xbox Live regions.
Individual prices for each of the 21 confirmed games-on-demand launch titles have not been announced.
The service arrives as part of the Xbox Live summer dashboard update, which rolls out on Tuesday 11th August.
