November 2019 edit: MV Crush is now paid out at 90% for one year! Details: https://www.manyvids.com/Article/5461/MV-Crush-Club-Upgrades/
The exact percentage of your ManyVids payout will depend on the type of service/what function is being used to pay for it. These numbers do change from time to time, but they are recent as of April 2020!
Custom videos, tips (either sent through Make it Rain or FundMe), Store Items, texting, video chat, phone calls, and
MV Crush are all paid out at 80%.
Videos from your store and contest votes are paid out at 60%.
Exceptions for ManyVids Payout
Vid sales made on your first MV Anniversary (anniversary from making your account) are paid out at 100% – this only happens once!
