# Working with reservations in MediaLive
<a name="reservations"></a>

A reservation is a one-year commitment to a particular input or output configuration. The reservation is allocated and billed on a monthly basis through that year. You can configure reservations to renew automatically.

You can purchase a reservation for processing resources that you are billed for, such as input processing, output processing, and add-ons like codec licenses. Each reservation gives you a reduced rate for the processing of the relevant resources. 

You pay an hourly rate for a pool of minutes that your channels consume for one month. For information about charges for reservations, see [the MediaLive price list](https://aws.amazon.com/medialive/pricing/).

**Important**  
If some or all of the minutes in a reservation are not used in the month, those minutes are lost. The minutes are not transferred to the next month.
