Unity processes payments at the end of each month on a net 60 cadence, which means that your outstanding balance is paid in full within 60 days of each payment period, so long as your earnings met or exceeded the minimum payout amount.
Because the minimum payment amount is $100, if you earn $50 in March, then $50 in April, the accumulated balance meets the minimum payment amount in April and is paid by the end of June.
Please also be aware that it can take a few days for the payout to be made to your account. Additionally, any changes made in Payout Profile might not affect payouts for the current month.
For additional information, please refer to the Unity Ads Revenue and Payment documentation.
