Contact the mining pool and inquire about their payment procedures. Most mining pools use the pay-per-share (PPS) and the pay-per-last-n-shares (PPLNS) methods to pay the mining rewards. When you use the PPS method you receive a predetermined amount per portion of the work.

However it is the PPLNS method is based on an algorithm that is weighted. Once a block has been mined it is then divided between the participants after they have mined another block. In this instance, the rewards for mining is calculated using the amount of shares you have submitted multiplied by the total number of shares that are submitted to the pool. The total number of shares submitted will then be multiplied with the reward from the block.

Another thing to keep in mind is that if you own an older ASIC miner that has low hash rates be sure to avoid pools with more high pay-per-hour thresholds. A lower computing power could cause lower revenue.
