Welcome back frugal fanatics! We’re so glad you’re here.

We get a lot of emails from readers asking questionsabouttheir specific situations. Of course, we love engaging with y’alland always try to answer each and every one of them.

Every once in a while, we come across a question we think could help the entire group, which is what happened when we received this email a few weeks ago. It comes from a reader named Georgia, and here is what she asks:

Hello Greg & Holly,

I really enjoy your blog, but I’m not sure that I am grasping the zero-sum base budget. How doI use what I made last month to fund this month? I’m missing something but I’m not sure what it is…Can you give me some enlightenment?

First of all, great question Georgia! Thanks for sending it. Your email hits straight at my heart.

Seriously guys, budgeting questions get me all kinds of excited!!! Itmeans somebody is trying to change their life, so I’m more than happy to oblige. With that said, forward ho!

What is a Zero-Sum Budget?

Let’s begin this discussion by defining one of my favorite topics of all-time – the zero-sum budget. In my opinion, if you learn how to use a zero-sum budget properly, you can totally change the course of your entire life.

Note that I said your entire life, not just your financial life. I truly believe getting your finances under control leads to a happier, less stressful life. Quite frankly, it’s also a life filled with more options. That’s the reason we started this blog, and it’s the thing that keeps us going still today!

So, what is a zero-sum budget?

Whelp, a zero-sum budget – sometimes called a zero-based budget – is a budgeting method that seeks to balance the amount of income you earneach month with the total amount of money you save and spend. To put it another way, you “zero-out” your income with your savings and expenses. Here’s an easy formula for you to remember:

Income – Savings – Expenses =Zero

I don’t want to spend a lot of time explaining how to create a zero-sum budget since we’ve covered itin the past. (Wedig into it even further in our new book, Zero Down Your Debt, hittingstores in January 2017). However, here are the basicsteps:

  1. Createcategories for all of your monthly bills.
  2. Take your monthly income and “spend” it into each category (including savings) until you’ve allocatedall of your income for the month.
  3. When your income, expenses, and savings balance to zero, you’ve created a basic zero-sum budget.

Using Last Month’s Income

Most people create their budget based on themoney they think is coming in. That has the potential to create problems due to income shortfalls. Ideally, you should try tobase your budget on moneyyou have already made. You want to base your budget on last month’s income.

By using last month’s income to budget,youeliminate almost all of the guessing. You already know exactly how much money you have to spend for the following month, which helps you avoid overspending. Even better, you’ve already got the money to pay for it, so you’re not scraping by to find a few extra bucks to pay the bills.

To do this effectively, use last month’s income to pay yourself a “salary” on the first of the month.This salary is based on your fixed and estimated expenses and should include justthe money you need to live that month. Any money you don’t use goes directly into some type of savings plan.

By paying yourself a salary based on your ACTUAL expenses, you’re setting yourself up for budgeting success. Instead of having extra money in your account that might get wasted, you’ll have exactly what you need.

So, instead of guessing how much money you think you have at your disposal, using last month’s income helps you be more exact. This leads to fewer mistakes, increased savings, and more specificity. And since this method provides more success, it usually leads to people sticking with their budget for a longer period of time…which of course perpetuates more success!

How Do I Save a Month’s Income?

Naturally, this leadsto the question, “How in the world do I save a whole month’s worth of income?”

The key is cutting your expenses to free up extra money.Take the money you save and put it in a separate “fund” for your one month nest egg.

Example Time!

Let’s look at an example. Suppose you earn $5,000 a month in take home pay. Your expenses equal $3,500 a month. That means you have $1,500 a month you can put toward saving a full month’s income. In just over 3 months, you should have enough saved to use your last month’s income to pay this month’s bills! Make sense?

Pro Tip: Saving your last month’s income is something that should be done above and beyond your emergency fund of 3 to 6 month’s expenses. If you already have your emergency fund in place, you’re good to start saving up for one month’s income. If not, start with your emergency fund first. Once you have it fully funded, move on to your one month’s income!

How to Use a Zero-Sum Budget Before You’ve Saved One Month’s Income

The fact is, most people who are new to budgeting don’t have a whole month’s income savedup when they start out. But, that doesn’t mean you should throw the zero-sum budget out with the bath water! In fact, the opposite is true. Using a zero-sum budget is an excellent way to stay deliberate with your savings goals!

The cool thing about a zero-sum budget is that you can use it even if you don’t have a full month’s worth of income saved up. Although it works best when you base it on money you have in hand, you can still use it when building that one-month buffer.

You probably have a good idea ofhow much you’re going to make each month; so, go with that! Use the same process and categories you would with any zero-sum budget, just substitute your estimated income for your actual income. Again, your income minus expenses and savings should equal zero. Any money you earn above and beyond what you’ve budgeted for should be squirreled away in your savings!

Tools for Budgeting

Being as exact as possible helps create an environment for budgeting success, and using your last month’s income is one of the best ways to ensure accuracy. You can also use tools – like Personal Captial’s free cash flow app – to help ensure you stay within your budget on a weekly basis.
