As simple as that

Hi,

As simple as that

Could you please explain the meaning of above sentence?

Regards,

In plain words, it means, “it’s quite easy to understand\do = not that complicated as you could think it is.”
–We can’t pay people more money until the company gets more profitable. It’s as simple as that.
–If you don’t know how to build the house, ask professionals. It’s as simple as that.
–Take the hammer and hit the nail on its head. Simple as that.

Thanks.
