Budgeting. There! I have said one of the scariest words someone struggling with financial freedom can hear.

 

There are many different types of budgets out there and many different ways to track them. Today I am going to teach you about my favourite method of budgeting: Zero-Sum Budgets.

Zero-Sum Budgeting

 

Rules:

There are two main rules that drive a Zero-Sum Budget:

 

1. Every dollar needs a job.

Each dollar of your income should be allocated for a specific purpose. When allocated correctly your income minus your expenses will equal zero.

Why would you ever want to have NO leftover money? Well, “extra” money can lead to frivolous spending. After paying all of your fixed expenses, if you have a balance remaining in your budget you may end up spending this extra money on things you don’t need. You may see $100 remaining on your budget, feel like you have a lot of extra cash, and decide to treat yourself to a night on the town. This will only drive you further away from your financial goals.

By assigning a job to this “extra” money, you are less likely to spend it on something you do not need. When you decide you want to go out for a night out, instead of looking at your bank balance, you will take a look at the ‘Dining Out’ category of your budget to see if you have enough money allocated for the night.

 

2. Live on last month’s income.

This is the rule that will allow you to stop living pay cheque to pay cheque. It is also the rule that I have struggled with the most.

This rule requires you to save enough money to go an ENTIRE month without touching your regular income. Then next month, you spend the previous month’s income while earning this month’s income.

How is this possible? When you start using this budget, you will allocate as much leftover income (after paying your fixed expenses) to a Buffer category. For example, if you have $1,000 left after paying for fixed expenses, you may choose to budget $500 to your Buffer and the remaining to discretionary spending categories. After saving for a few months your Buffer should equal your income for one month. Once you have that money saved, you’re golden! Simply use the money in your Buffer to pay for this months income.

By living on last month’s income you reduce the amount of stress your finances can cause on your life. You will always have some money in your bank account in case an emergency arises.

 

You Need A Budget

Does this sound way to complicated? I promise it’s not!

I was introduced to Zero-Sum budgeting through a post on Budget’s Are Sexy. The software seemed super easy to use and I loved all of the learning tools they provided (for FREE).

The program looks something like this every month:

You Need a Budget

On the left-hand side, you can set the categories of your budget. There are many different ways to set up your categories. Personally, I like to categorize the majority of my categories into Fixed Expenses and Flexible Expenses.

Fixed expenses are all of the non-variable expenses that I have to pay. This means that the cost of these expenses is the same month over month.

Flexible Expenses is my “everything else” group. This is where I put the expenses that vary in cost month by month. This grouping includes categories such as groceries, dining out, and clothing. I choose to categorize my expenses this way because it allows me to see what areas I can cut back on spending. I know I cannot easily change my fixed expenses, so sorting my expenses in this way allows me to see which variable categories I am overspending on.

Stuff I Forgot To Budget For

Regardless of what budgeting method you decide to use, it is important to remember that budgets are meant to be flexible. By allowing yourself to be flexible with your budget you are less likely to become discouraged if you happen to go over in one category.

So, how can you have a flexible budget? If you are using a zero-sum budget it is super easy to maintain some flexibility. You may have budgeted $50 to dining out for the month of January, but near the end of the month, you notice that you accidently went over budget and your category is now over budget at $75. This is okay! Look at your budget and see if there are any categories are under budget. You may find that you are under budget on groceries for the month. All you need to do is remove $25 from your grocery budget and slot it into your Dining Out category. Now you are back on track with your budget!

In my budget, I also choose to include a “Stuff I Forgot to Budget For”. Sometimes, strange expenses come up and you won’t know where to categorize the expenses. By having this category available for those smaller random expenses, I am able to have additional flexibility while budgeting.

I love zero-sum budgeting because it is motivating, goal-orientated, and extremely flexible.

  1. Great post! Normally my budget always has a balance. However, after reading this, I am going to create a “Forgotten Items” category and put the funds there.

    1. Hi, Sylvia. Thanks for commenting! I honestly love having a ‘Stuff I Forgot to Budget For’ category. Sometimes random expenses pop up and it’s nice to know you have some flexibility!

  2. I personally like to use Personal Capital as my budgeting tool but I have definitely played around with YNAB and enjoyed it’s interface. It definitely took me a couple of years before I completely understood the concept of why a zero based budget was so important. But now that I do it’s so much easier. Knowing where each dollar belongs is so much easier.

    1. It also took me quite a while to understand zero based budgeting but I absolutely love it now. I am constantly reading up on how to make my budget an even more useful tool.

  3. I use the website calendarbudget.com for my budget needs. It’s super simple and allows you to see into the future how much money you’re going to have at any given point. So you can program in all of your recurring bills and incomes and see where you’re really at. I was in really bad shape when I started using it and now I’m doing so much better. I actually have money in savings for the first time in a long time.

    1. I’ve never heard of calendar budget before. I’ll definitely have to take a look. Thanks for sharing!

    Really helpful advice. I usually do not budget for anything but this time I’m definitely going to try budgeting.

    1. Thanks for commenting! I definitely used to think budgeting was overrated. But now that I’ve learned how to be flexible with it, it has actually become sort of fun!

  5. Yes! Love this method of budgeting. It works! We use Every Dollar for our budget every month.

    1. It really is a great way to budget!

  6. This is a great idea. I have 3 young adult children just really starting out. 1 in college and with 2 jobs is struggling financially, 1 21 y/o about to move out on her own and is a little afraid and 1 who just came home from the military and starts his first day of school tomorrow. He’s hoping to move out soon but just doesn’t know how he will do it. I will be sending them all your way!

    1. Oh wow! Sounds like they are all in some tough places! As someone who struggled for many years after moving out, I HIGHLY recommend starting to budget and tracking where you spend your money. It really is eye opening. Every little expenditure adds up!
