The value of your upvote is based on several different factors.
Some factors are current Market Value of Steem, and the number of people using the steemit system. Those factors are controlled by the market.
Other factors are, your current Steem Power and Your Voting Power.
What is Steem Power?
Steem Power or SP is the amount of Steem you have vested in the Steemit community.
You can obtain steem power by buying it, receiving a delegation (someone lets you use their SP), or earning it (by blogging and/or commenting on Steemit).
You can see the amount of SteemPower you have in your steemit wallet.
In this wallet you can see 0.240 Steem, 257.119 STEEM POWER and 10.238 STEEM DOLLARS
What is Voting Power?
Voting Power, is the amount of power your upvote has.
You get Voting Power just for having a steemit account.
Everyone Starts with 100% Voting Power.
Every time you upvote something, your voting power goes lower, your voting power regenerates on its own.
I track my voting power using https://steemworld.org/@metzli. Replace 
The Chart above can be found on the top left corner of steemworld. It tells you what your voting power is and how much your upvote is worth.
If your voting power is too low, stop upvoting and wait for your account to be regenerated.
The Chart above is also on steemworld, towards the middle of the page. The box, with a line that says vp --> 100% (I circled it) that value tells you how long it will take to get your upvote to 100%
Those are the tools I use to see how much value my upvote has.
But how much is an upvote really worth?
By looking at the charts, it would seem that the upvote being shown on the chart is worth $0.050 but $0.050 whats?
SteemUnits
The picture above is from one of my blog posts. You see that the Post is worth $9.68 Steem Units. If you click on that number, a box pops up which tells you what $9.68 Steem Units Converts to. Roughly $4.84 SBD and $1.60 STEEM POWER.
At payout. The author receives 75% of the SBD and 75% of the STEEM POWER. Please note that $75% is a rough estimate.
That is the same way your upvote get valued
This is why steem dust exists, and why it is not recommended to upvote posts or comments that have a total value of $.03 units or less. By the time your upvote gets converted from Steem Units to SteemDollars/SteemPower and then divided amongst author and curator, if the numbers are too small for the system to register, your efforts turn to dust and disappear.
