Doing a little redecorating or rearranging of your YNAB budget categories?
A common YNAB rookie (or not-so-rookie) error is getting too granular with budget categories. I once experimented with separating my chocolate purchases out from our general grocery spending. Huge mistake!
For one thing, it turned out to be information I did not want to know. And B, it was a huge PITA (pain in the tuchus). All those split transactions kept me from entering my transactions right there in the grocery store — never a good idea.
Anyway, whatever your reason for wanting to merge or combine existing categories, it’s actually a simple task. But if you don’t follow the right steps you can really muck up your budget. And untangling the mess can be a nearly impossible task (ask me how I know).
3-Step Process for combining YNAB categories
Step 0: Establish terms and define project
Make sure you’re clear about what your goal is before you start. If you have several categories to be eliminated, complete all three steps for a single category before proceeding to the next category. Trying to combine steps could result in a hairy, tangled mess. [The new web-based YNAB’s lack of “walled months” makes it impossible to pick apart what went wrong, where puzzles. Ignore my advice at your own peril.
Terminology:
- Host category – the category that will remain and be expanded
- Abandoned category – the category this is being eliminated
For demonstration purposes, I’m going to merge my Non-grocery Grocery Store category into my Groceries category.

In the search box on the All Accounts screen, begin typing in the name of the category to be abandoned. In my demo case I started typing “non” and YNAB’s search function suggested several options including everything categorized to Non-grocery Grocery Store (see below).
Click on the line: Category: [your abandoned category name] and YNAB will display all of the transactions assigned to that category.

Now you’ve got a full list of transactions assigned to the category you want to eliminate. Select all of the transactions by clicking on the checkbox in the header column (see top screenshot below).
Once all of the transactions are selected, use the Edit menu to move them, en masse, to the Host category — in this case, to Groceries (see bottom screenshot below).
Click on Edit => Categorize => then hover over your category group names until you see the Host or destination category name. Click on the Host category name to finish the process.


Step 2: Clean Up the Budget
Now that all of your transactions have been recategorized, it’s time to clean up the Budget screen.
This is an important step in the process. Don’t skip it.
In the Budget screen, you need to remove all allocations made to the Abandoned category and add them into the Host category allocations. This process needs to be repeated for every single month in your budget file.
Start in your most recent month and move backward or start in your very first YNAB month and move forward. Either way, make sure you move methodically through your entire budget.


Any transactions or allocations you miss will end up as free-floating numbers once you delete the category. These free-floating allocations, in particular, can create a real mess.

Step 3: Remove or Rename the Category
The final step is to either repurpose the now-empty category by renaming it.
Or you can delete it and be done with it.
If the purpose is to cut back on the number of categories and simplify, then deleting the category is the best choice. But if you’re reorganizing, save yourself a few steps by repurposing the category.

And that’s it!
Don’t be afraid to customize YNAB and make it your own. In that process, you might find that your categories aren’t set up quite right. Combining categories is a great way to clean up your data and make it work for you.
What categories did you experiment with only to discover they were useless or redundant or too granular?
Thank you so much for this article. It was very helpful to me, and saved me from a mess.
Thanks for your comment, Joanne. Happy to have helped!
My issue is that I have Master Categories for Truck (Pre 2015), Car (2015-2019), Van(2019-now); each with sub categories for gas, insurance, etc.
I thought it might be a good idea to merge those categories into “Transpo”. But apparently, unless I want to go back and individual update 8 years of budget entries (96 months, “not all that many”.), there is not a “simple way ” to do this.
Nerts. YNAB is a good budgeting program, but not necessarily a good “accounting” program. I’ll just live with it.
Well, the merging part of the process would be fairly straightforward. And you *could* skip step 2, if you wanted to and simply fix the allocation discrepancies in the current month. This would make your budget history look messy but in the end all the numbers would be the same.
I happen to disagree with your statement that “YNAB is a good budgeting program, but not necessarily a good ‘accounting’ program” but I understand your position.
Very helpful. Thanks for the walk-thru.
