There's no way I can go traveling now. Even if I ever decide to go, I would have to save up first.

I would say like this. Not 100% confident, though. I can't afford to travel abroard right now. I would do when/if I saved enough money.

Hi, The word-for-word translation would be: It's impossible to travel now. If I travel (/ went), it'll be after I save money. However, I think it sounds unnatural in English and I would do as Kota-san did.

行くとしたら if I went お金を貯めてからです。 it would be when I had saved money. Something like this?

Thank you for your comment. But why is the としたら attached to 行く and not to 貯める？
