Yesterday, I downvoted an answer that I thought was wrong, and also added a comment that it was I who downvoted and why. Today, I see that I have a -1 in my reputation because of the downvote. Is it expected that the downvoter's reputation is reduced by 1?

It could be justified to prevent frivolous downvoting by making the downvoter pay for the action. I would just like to have that confirmed.

    i think if other users do the same you will get back the subtracted 1 point – Badr Bellaj Nov 23 '17 at 18:23

    Yes, other users downvoting the same thing makes it more likely for the system to remove the item which will give you back the 1 reputation: meta.stackexchange.com/questions/5221/… – eth Nov 26 '17 at 12:57

Yes.

Downvoting an answer will cost you 1 point of reputation. The poster of the answer you downvoted will lose 2 points.

Downvoting a question will cost you nothing.

The full description of every way to gain or lose reputation is on the main meta site:
