Daily Fees for Hashlets: $0.08 USD per 1 MH/s (Script) and $0.01 USD per 5 GH/s (SHA). On 10/17/2014, GAW gave a 50% bonus to all SHA miners. So a 10 GH/s turned into a 15 GH/s miner. As a result, mining fees for SHA-based Hashlets are now listed in 5 GH/s increments.
Due to the wild fluctuations in BTC value, the maintenance fees reflect those swings. This graph is meant to serve as a companion to the gross and net payout trackers.
