How to predict on demand usage better?

So I wasn’t aware when you selected on demand usage and entered in an amount that it didn’t automatically deduct that money from your account and put it in the app, but instead let’s go use that money then pay it over the next month.

I add maybe $10 every other day and I’m getting these “mid month usage paid” messages in billing on cursor dashboard for a fraction of what I transferred for on demand usage.

Obviously by the end of the subscription for that month I’ll owe all the on demand usage, BUT is there a more reliable way to see when these smaller invoices are going to hit? Just from a money tracking perspective?
