Fundbox Plus costs $99/month.
Fundbox Plus renews automatically every month and can be canceled at any time. If you cancel, you can continue to enjoy the benefits through the end of the current billing period. For example, if you upgrade on October 1 and cancel on October 21, you can continue to enjoy the benefits of Plus through October 31—on November 1 you will not be debited for the Plus fee again and you will no longer be eligible for benefits going forward.
