Simplifying Budget Categories and Sinking Funds (or “Future Spending”)

Categories and sinking funds can make budgeting feel way more complicated than it needs to be. If you’ve ever felt overwhelmed by too many budget categories or frustrated by trying to track every little expense, this post is for you.

Let’s make it simple and realistic, the way budgeting should be.

What Even Is a Sinking Fund?

So, here’s the deal. A sinking fund is just money you’re setting aside for future expenses, things you know are coming, like birthdays, Christmas, car insurance, or hair appointments.

I’ve never really loved the term “sinking fund” (my brain just doesn’t get it). I like calling it future spending instead, because that’s what it is, planning ahead for the stuff we know we’ll spend money on later.

Instead of having a bunch of little accounts for each of those categories, I keep one big high-yield savings account. That way, the money earns the most interest while it’s sitting there.

Then I track everything on paper and in my Google Sheets Budget Tracker. Inside the spreadsheet, I label each “fund” separately: birthday, Christmas, insurance, etc., even though the actual money is all sitting together in one place. It’s simple, clean, and easy to manage.

My Simple System for Budget Categories

Here’s where I keep it really simple. Once I’ve written out my transactions, I group them into categories, but not in an overly complicated way.

Here’s what that usually looks like for me:

Aldi + Walmart → Groceries
Target, Amazon, Costco → Each are their own category.

Instead of breaking everything down into tiny pieces like “beauty,” “pets,” or “household,” I group by store. It’s faster, cleaner, and makes more sense to me. Everyone’s brain works differently, but for me, this keeps things easy to track without overthinking it.

Why I Still Write Out My Spending by Hand

Every paycheck, I download my spending from my bank, and then I write it out by hand using my printable Spending Tracker.

I know it sounds old-school, but I swear it helps me stay aware of what’s actually happening with our money. When you see “Aldi, Target, Amazon, Aldi, Walmart, Target” over and over again online, it just looks like noise.

But when you write it out, your brain slows down enough to actually process where that money went. It’s a game-changer.

My favorite tools: I use Frixion erasable pens and highlighters, they’re the only reason I can budget on paper without getting frustrated!

Sometimes I color code, sometimes I don’t; it totally depends on my mood and energy level that day.

How I Pay Bills (and Still Get Reward Points)

When it comes to utilities and other bills, we pay them with our credit card first. Not because we’re carrying debt, but because:

It’s safer online.
We earn reward points and cash back.
It’s easier to track everything in one place.

At the end of each pay period, I pay the balance off from our checking account right away. I don’t wait until the next statement date.

To keep things organized, I make each payment match the exact bill. For example:

Gas bill: $36.66 → Payment: $36.66
Water bill: $175.10 → Payment: $175.10

That way, when I look at my credit card statement, it’s super clear which bill each payment belongs to. Easy-peasy.

Adjusting Your Budget as You Go

Here’s something I’ve learned after years of budgeting: it’s always changing.

Your budget isn’t static, it’s a living document that evolves with your life.

For example, recently I budgeted $200 for my husband’s birthday, thinking it was plenty. The outing alone ended up costing $175. So yeah… lesson learned! Next time I’ll plan for a bit more.

The same goes for things like prescriptions. Some months we spend nothing, and then it all hits at once. It’s totally normal. Tracking helps you see those patterns so you can plan better next time.

Why I Don’t Over-Categorize

If you take one thing away from this post, let it be this: Don’t overcategorize your budget.

If you’re breaking down every Target purchase into “groceries,” “beauty,” “pet,” and “household,” you’re going to drive yourself crazy.

Budgeting should make your life easier, not more complicated.

Keep your categories broad enough to be useful, but simple enough to maintain. The goal is awareness and progress, not perfection.
