# Sailbox Pricing

> Observed usage billing dimensions and rates for Sailboxes

Sailboxes bill for observed usage: the CPU, memory, and disk a Sailbox
actually uses while running, plus a one-time charge when it is created. How
that works, what each size includes, and where to see your spend are on the
[Billing overview](/sailboxes-billing). These are the rates:

| Dimension                                                                                                                                                                                | Price    |

Usage accrues only while a Sailbox is running. Sleeping, paused,
checkpointing, and cold-starting time is not sampled and not billed. Usage is
sampled about every 15 seconds.
