Per section 18.6 of FanDuel's Terms of Use, if your account is inactive (no free/paid entries, deposits, or withdrawals) for a twenty-four (24) month period, you will be assessed a $2.99 inactivity fee. This fee would be deducted from existing funds in your FanDuel account balance. No outside payment sources would be charged.
You can avoid an inactivity fee by entering any contest (free or paid), depositing funds, or withdrawing funds.
If you're having trouble accessing your account or withdrawing your balance, please contact our Support team.
