Your campaign budget is the amount you want to spend over the duration of your campaign. Your Ads Manager campaigns are billed using the currency you selected when creating your ad account

There won't be additional charges if your campaign delivers over the amount you set. If your goal isn’t reached, you’ll only be billed for what was delivered.

Lifetime budget

Lifetime budgets are required on all campaigns and must be $500 or more. They define the amount of money you'd like to spend over the course of your campaign's scheduled flight. Roku Ads Manager will deliver your budget throughout your scheduled flight, optimizing automatically based on your pre-selected objectives, goals, and targeting.

Understanding budget pacing
Roku only bills you on delivered spend that fits within the lifetime budget and schedule you set.

When campaigns overdeliver

You won't be charged for any spend over your planned lifetime budget. If your campaign overdelivers and budget is spent above your lifetime budget goal, you'll only spend what you planned.

When campaigns underdeliver

You'll only be charged for what delivers and you're never charged for any remaining budget. If your campaign underdelivers and there's money left but your schedule has ended, the unspent budget is yours to reallocate.

Schedule

The schedule defines the date and time period in which your video creatives will be shown to the audience you’ve selected within your specified geographic location.

Date range
When choosing the date range for your campaign, you must set it to start on a future date.

Time zone
When creating your ad account, you’ll set the time zone. Choose carefully as this can’t be changed once you create the account. You'd need to create a new ad account to utilize a different time zone.
​
Your report data will be shown in the time zone you selected, and your campaigns will also deliver in that time zone.
