FROM HASHNEST DOC https://www.hashnest.com/contracts/new?contract_id=2
Profit Calculation Method
Unpaid principal (BTC) * 0.45 (satoshis per BTC per second) * time to find a block (seconds)
For every block found, the remaining payout after the profit is paid will count towards the principal payment. After each principal payment is made, the amount is subtracted from the amount of remaining principal.
Please note: information on blocks found will only be transfered to Hashnest.com from AntPool after receiving six network confirmations. Because of this, profit and principal payments will be on a slight delay from the network.
