kick in

"We are buying a keg of beer for a party. You guys want to kick in something?" Is it OK with the use of "kick in"?

OR

"The more money you get, the more benefits kick in."

"We are buying a keg of beer for a party. You guys want to kick in something?"

That is correct.

That is correct.

What about the second one meaning that the more money you get the more benefits start to heve an influence on your life?

Suppose you had a head ache and took some painkillers, can you say:

"I could feel the pain killers kick in."

"I could feel the pain killers kick in."

Yes. Another example:" Retirement benefits kick in when you turn 65."
I don´t think you can use it as you did in the second sentence, "The more money you get........."
