Usage rights fee calculator
Work out what a brand owes when it keeps running a creator's ad after the usage window ends. Enter the deal's rate and how long the ad ran past the end date. Free, no sign-up, nothing saved.
Enter the usage end date and the date the ad was last seen.
How the amount is worked out
The amount is the deal's usage rate per 30 days, applied to every day the ad ran after the end date:
amount owed = rate per 30 days ÷ 30 × days past the end date
The rate per 30 days is either a fixed amount from your contract, or a percentage of the original fee. For example, a $4,000 deal at 25% per 30 days has a rate of $1,000 per 30 days. If the ad ran 60 days past the end date, the brand owes $1,000 ÷ 30 × 60 = $2,000.
Some contracts charge in whole 30-day periods instead, where any part of a period counts as a full one. On the same deal, an ad that ran 32 days over is 2 periods: $2,000.
Days count from the day after the usage end date to the last day the ad was seen live. This is the same calculation Usage Hawk uses for every confirmed ad.
Where 25% per 30 days comes from
There's no fixed industry rate. 25% of the original fee for each 30 days is a common starting point: one whitelisting rate guide calls 25% of the base deal per 30 days a reasonable rate (Top Growth Marketing, checked October 18, 2026). It's the default here and in Usage Hawk. If your contract names an extension rate, use that instead.
Frequently asked questions
How much should I charge for usage rights after the deal ends?
Use the extension rate in your contract if there is one. If there isn't, 25% of the original fee per 30 days is a common starting point, and many creators charge more for whitelisting or exclusivity.
Do I charge by the day or for a full 30 days?
Check your contract. Charging by the day (rate ÷ 30 × days) is the gentler option and easy to defend. Some contracts bill in whole 30-day periods, so 31 days over counts as 2 periods.
When do the extra days start counting?
From the day after the usage end date, up to the last day the ad was seen live. An ad last seen on the end date itself is within the deal.
What if I don't know when the ad started running?
You don't need to. What matters is the agreed end date and the last day the ad was live after it. Meta's Ad Library shows the date an active ad started running, which helps you check the dates in your notice.
Is the result legally binding?
No. It's a suggestion based on the terms you enter, not legal advice. Your contract decides what the brand owes.
Can Usage Hawk do this for every deal automatically?
Yes. Usage Hawk checks Meta's Ad Library every day once a deal's usage window ends, and when you confirm a match it works out the amount with this same calculation and drafts the notice.
Before you send the number
Check the dates against the Ad Library, screenshot the ad while it's still live, and keep the message friendly: most overruns are a forgotten end date, not a plan. Compare the types of tool that track this for you in our guide to usage rights tracking tools.
