They have been running a daily 2,000,000 token distribution cap. So basically that figure of tokens is split between all participating in that days distribution cap.
e.g. today at the moment of writing there is 1,676 ether in the pot, so everyone would get  1,193 EOS per ETH.

It fluctuates, some days are better than others in terms of how many people contribute.
After 350 days, that will be all the tokens distributed. We are at day 200.

Alternatively you can take the market price on any Exchanges which will be based on how many EOS have been distributed so far.
