Doesn't Understand fine tuned model cost

I’m not sure how you would do a finetune with only 500 tokens unless you were just doing 1 or 2 word prompts and completions.

I’m near my hard limit of $120 for fine tuning and I have a similar question on the calculation of the pricing. I have 270700 tokens in my doc and the cost should be (270700 / 1000 * $0.03) $8.12. I’m wondering if the fine tunes are double, triple or quadruple counted because they have to be processed multiple time? I did the napkin math on the token usage I’ve had and it seems like I’m being over-charged, unless there is something more to the calculation I don’t understand.
