I used Claude about a week ago to do a pretty intensive refactoring. Cleanup, initial modularisation, beginnings of a test suite, and better isolated build. In a span of couple of hours, and over a sequence of 20+ new commits, I burned a hair over $100 in tokens.

If you are working on a seriously large legacy code base, I can see how you'd get to >$250 on a bad day.
