a single vocabulary item as synonym for hidden fees

There is a word I remember seeing some time ago, but unfortunately I have now forgotten.

The definition was like this: to pay an amount which is more than expected, similar to hidden fees.

I think it was a verb or noun. For example, you buy something but there are hidden fees and you have to pay extra.

Please help me out.
