It makes sense; it is as I expected or might have guessed. A: "Sally already broke up with that new boyfriend of hers." B: "Yeah, it figures. The dude looked like a total creep!" Fired from another job, huh? Well, it figures. You were showing up late most days of the week!
It makes sense.; It confirms what one might have guessed.; I'm not surprised. Bob: Tom was the one who broke the window. Bill: It figures. He's very careless. Ann: Mary was the last one to arrive. Sally: It figures. She's always late.
Also, that figures. It's (or that's) reasonable; it makes sense. For example, Hanging it upside down sounds like a weird idea, but it figures, or It figures that they won't be coming this year, or So she's complaining again; that figures. This idiom alludes to reckoning up numbers. [Colloquial; mid-1900s]
