You can go to Steem Now, plug in your username, and play around with the slider to see what your upvote is worth.

ATM your power is at 29%, and a 100% upvote is worth 4 cents. So we might expect a 13 cent vote when you're fully recharged.

If your goal is to have a $1 upvote, you'd need to have something like 8x more SP.
