After people tried to explain a zero-based budget to me, I thought I actually had a good understanding of the method, but I had never actually tried it myself before. People told me that figuring out “which dollar goes where” opens a full new understanding of “how your finances work. ”
So, I took the plunge. I even went the extra mile and did it for a full three months. It was a wild ride, but I accomplished my goal.
What is a Zero-Based Budget?
Up until a few months ago, I had no experience with this type of budgeting. After being explained to me, the theory of a zero-based budget is as follows:
Zero-based budget: Income – Expenses = 0
Every dollar is “assigned” to a budget category. It could be the following: rent, grocery shopping, savings, debt repayment, and even discretionary spending. Categorizing all your assigned budget dollar amounts is supposed to let you zero out at the end of the month.
EX: It breaks down like this: if you make $3,000 a month, you should be able to categorize your budget like this: $1,200 rent, $400 groceries, $300 car, $200 savings, and so on until you assign all your dollars to specific categories.
A lot of people find this method to be very organized, but unfortunately, it is probably the most tedious method out there.
Month 1: The Honeymoon Phase (Everything Was Great)
April 2024. I sat down with a spreadsheet and my bank statement from March.
What I did:
- Listed my income: $2,847 (after taxes)
- Listed every category I could think of (23 categories total – probably too many)
- Assigned dollar amounts until I hit exactly zero
My categories included:
Rent: $875
Car payment: $280
Insurance: $148
Groceries: $250
Gas: $120
Utilities: $85
Phone: $35
Subscriptions: $47
Eating out: $150
Fun money: $100
Emergency fund: $200
Debt payoff: $250
Miscellaneous: $107
Total: $2,847. Perfect zero.
Week 1 felt amazing. I knew exactly what I could spend on groceries. I knew I had $150 for restaurants. Everything was planned.
Week I got cocky. Spent $47 on groceries, felt like a budget genius.
Week 3 reality hit. My car needed an oil change ($65). I’d only budgeted $50 in “car maintenance.” Where does the extra $15 come from?
This is where zero-based budgeting gets annoying.
The Problem Nobody Warns You About
You can’t just spend the extra $15.
In a zero-based budget, every dollar is already assigned. So if you overspend in one category, you have to take money from another category.
My oil change was $65. I’d budgeted $50. I had to “steal” $15 from somewhere.
My options:
- Take it from “fun money” (goodbye coffee shop)
- Take it from “eating out” (one less restaurant meal)
- Take it from “groceries” (eat ramen for 3 days)
I took it from eating out. Made sense. But it was annoying to track.
This happened like 6 times in month 1. Overspent on gas by $18, had to adjust groceries. Bought a birthday gift ($35), had to pull from fun money and miscellaneous.
Did it work? Yeah. I stayed on budget.
Was it tedious? Also yeah.
Month 2: The Adjustment Period (I Almost Quit)
May 2024. I refined my categories from 23 down to 15. Too many categories = too much micromanaging.
New strategy:
- Combined small categories (utilities + phone = $120 total)
- Increased “miscellaneous” buffer from $107 to $200
- This gave me breathing room for unexpected stuff
What went wrong:
- Got sick, needed urgent care ($89 copay) – had to raid the emergency fund category
- Car registration came due ($156) – I’d completely forgotten about this
- Friend’s wedding gift ($50) – didn’t budget for this either
By week 3 of May, I was so frustrated I almost gave up.
The problem wasn’t the budget. The problem was that life doesn’t fit into neat categories.
Month 3: I Finally Figured It Out (Sort Of)
June 2024. I made one big change that saved the whole system:
I added a “sinking funds” category.
Basically, I started saving monthly for expenses I KNEW were coming but couldn’t predict exactly when:
- Car maintenance: $75/month (averaged over the year)
- Medical: $50/month
- Gifts/events: $40/month
- Annual expenses (registration, etc.): $35/month
Total: $200/month into “planned irregular expenses.”
When my car needed brake pads in June ($240), I had $225 saved in the car maintenance fund. Only needed to pull $15 from somewhere else instead of $240.
This made zero-based budgeting actually sustainable.
Budgeting rules like 50/30/20 can serve as a starting point before switching to zero-based budgeting.
What Actually Worked vs What Didn’t
WORKED
1. Forced me to be intentional
Before zero-based budgeting, I’d just spend until my account looked low, then panic. Now I knew exactly what I could spend on everything.
2. Found money I was wasting
Turns out I was spending $90/month on “random Amazon purchases.” When I had to assign that $90 to a category, I realized how dumb it was.
3. Savings became non-negotiable
$200 went to the emergency fund every month because it was assigned. Before this, savings were “whatever’s left” (usually $0-30).
DIDN’T WORK
1. Too extreme to start
23 categories were out of whack. Tracking every $5 coffee separately from “eating out” was an extreme.
2. Didn’t plan for irregular expenses
This was almost the end of the line for the whole system until I added sinking funds.
3. Required endless tweaking
I had to rearrange money every time I overspent by $10 somewhere. It was accurate but mental.
Is Zero-Based Budgeting Worth It?
Depends on your personality.
You will most likely enjoy this if:
- You enjoy paying attention to multiple aspects of things.
- You enjoy having total control over your finances.
- You can dedicate 2-3 hours a month to budgeting.
- You need to hold yourself accountable when managing your expenses (like having a budget for every dollar).
You will most likely dislike this if:
- You prefer things that are simple and automated.
- You dislike having to monitor your spending.
- You have a variable income (this plan works with a steady paycheck).
- You prefer spending 30 minutes budgeting rather than 3 hours.
What I’m Doing Now (4 Months Later)
I still have a modified zero-based budget, and it’s much simpler now:
8 categories total:
- Fixed expenses (rent, car, insurance) – $1,303
- Variable expenses (groceries, gas, utilities) – $455
- Debt repayment – $250
- Emergency fund – $200
- Sinking funds – $200
- Discretionary spending – $150
- Eating out – $100
- $189 buffer (to have an extra spending category)
Total = $2847 with every dollar budgeted (none are unallocated)
Now it only takes 45 minutes to update instead of 3 hours.
The bottom line: zero-based budgeting only works if you adjust it to your life and not just follow an Instagram budget template.
Start with the basics, and if you need to add complexity to your budget, do it. Also, for the love of budgeting, set your sinking funds from the very beginning.
