Calculating Usage Fees for Videography

Question

Hey all! I'm looking for some help calculating usage fees for videography as I can't seem to find a solid answer from Google.

Does anyone have experience in calculating usage fees for brands, for video (not photography)? How does one go about this? I'm a self-shooter and editor, so creating various videos for brands' websites and socials. The usage length is from typically 6 to 12 months and pretty much only online and in the UK.

Thanks in advance for any help!
