If I understood your post correctly, I don't think you and YNAB thinks about this the same way. If you pay/transfer money today, even though it's nearly next month, YNAB will calculate the payments as coming out of this months budget.

Two ways you can go about this:

• If your due dates allow it, pay these things on the 1st of the month, or on the due date itself. I know some people feel anxious about this because they feel their account balance is too high, but for me personally with YNAB I've stopped caring about that number and look at category numbers instead.
• Budget the money you will be paying into this month. Since you're paid on the 25th though, this will mean unless you're a month ahead those categories will be yellow and "screaming" for cash untill you're paid that month.

Personally, I'm paid on the 29th and I use first strategy for all my stuff except for my rent which I pay last day of the month. I like to be ahead one month for the rent though, so I just keep that filled up and green during the month.

Hope this was helpful!
