From privileges page of vote-down

What happens when I vote down?

When you vote down, you are nudging that content "down" the page, so it will be seen by fewer people. Voting down answers is not something we want you to take lightly, so it is not free.

  • Downvotes remove 2 reputation from the post owner.
  • Downvotes on answers remove 1 reputation from you, the voter.

So you will have to pay 1 reputation to down-vote the answer.
