# Execution Time

By default, each UbiFunction times out after 30 seconds. To extend this limit, [contact our support team](https://help.ubidots.com/en/articles/4683984-need-support-find-ubidots-in-app-chat-channel).

{% hint style="info" %}
UbiFunctions are billed per million executions. If an execution runs longer than 2 seconds, it counts as 2 executions or more, based on its duration. **The cost is $5 per million UbiFunction executions.**

Keep this in mind when increasing the execution time. You can check your UbiFunctions usage in your [account profile](https://industrial.ubidots.com/accounts/me/usage).
