That is affordable? Is it not right?

It isn't. "cheap" and "affordable" are not the same thing.

A Ferrari costing $40.000 would be a cheap Ferrari, but not affordable for me.

A chocolate bar costing $10 would be an expensive chocolate bar, but still affordable for me.

What could affordable mean in German?

erschwinglich

Why is "This is cheap" wrong?

[mizinamo]

It's not wrong. It's one of the accepted answers.

"That is low budget" is correct and "That is low cost" is incorrect?!?! Come on.

[Buddha_Bunny]

If anything, the first should be excluded. Budget and cost are two different concepts. Planned vs actual.
