The $0.01 that you see is an estimate. The value may increase or decrease depending on how much of the reward pool is used up.

Also, the reward that you see is rounded up. This means that even if the reward payout is $0.005, it will show up as $0.01 as there is no third digit next to your post payout. But when you get a payment, you will end up with something like 0.002 SBD and 0.003 SP.

That being said, you also need to bear in mind that you only get 75% of the reward and 25% of the reward is given to curators (Those who upvoted you)
