it’s swings and roundabouts

-na mostu izgubiš, na ćupriji dobiješ

also:  what you lose on the swings, you gain on the roundabouts

If you make more money, you have to pay more tax, so what we gain on the swings, we lose on the roundabouts.
It’s swings and roundabouts, really. If you save money by buying a house out of town, you pay more to travel to work.
