Hi Gelo,
I would second Mark's suggestion of building a month's table, this would help you to easily see your budget each month in one place and be able to run reports on those aggregate numbers outside of a summary report. We have an article
Quick Base Analytics: Improve your monthly insights by implementing a Months table that walks through setting up a months table in QB to get insights like this that might help you get started and understand how you would set something like this up.
