How to Stay on Budget with Two Simple Numbers

Satisfied young woman holding hand behind head and drinking coffee because she has any easy budgeting plan with Think and Talk Money.

Most of us humans are pretty good at avoiding things we don’t like. The things I’ve done to avoid mayonnaise…

Budgeting falls into this category of avoidance. Even though most of us can appreciate that budgeting is a crucial step in money wellness, we still avoid it.

Some of us give it a shot, and usually quit before we notice meaningful improvements. Just as problematic, some of us obsess over our budgets in an unhealthy and unsustainable way. This was me for a while. My obsession was mint.com.

I didn’t have a healthy relationship with budgeting apps.

If you used mint.com like I did before it ended, do you also have nightmares about those red tracking bars? Mint.com users know exactly what I mean. Overspend $11 on groceries? Red bar. One too many lunches downtown? Red bar! A last minute Saturday morning yoga class? RED! BAR!

It still pains me to think about how many hours of my life I wasted trying to recategorize expenditures so those red bars would turn green. If I just move this box of cereal from Groceries to Social Life, that Groceries bar will turn green. Oh wait, now Social Life is red. OK, move those movie tickets to Car Repairs.

When my wife was still courting me, I introduced her to mint.com. You might be thinking, “Matt, why on earth would you introduce her to something that drove you crazy!?” Valid question.

She was a good sport and gave it a shot for a little while. Thankfully, she was smart enough to realize tracking every penny wasn’t for her. The whole thing gave her more anxiety about money. Think about that. The idea was to create a plan for her next dollar so she didn’t have to worry about money. All I did was make it worse by introducing her to a budgeting app.

There’s an alternative to tracking every penny for the rest of your life.

That experience paved the way for my preferred budgeting method that my wife and I still use today. We discussed this method briefly in our recent Q&A post.

Please keep in mind this method is for people who have already created a Budget After Thinking and are honestly dedicated to creating fuel for their Later Money. Only when you get to that point will you no longer need to track every penny. At that point, your money motivations will be so strong that you’ll stay on track without needing to track every expenditure.

If you’re not there yet, don’t worry. You will be soon. Follow my top ten budgeting strategies until good habits become second nature. Then, move on to this simple plan.

My preferred tracking method is a version of zero-based budgeting.

Zero-based budgeting was first introduced in the 1970s by Peter Pyhrr. (I don’t love the name, either.) The main idea is that every dollar has a job, something we already talked about in our conversation about eliminating disappearing dollars.

In my version of zero-based budgeting, you don’t need to track every penny. You don’t need budgeting apps or complicated spreadsheets.

You’ll only need to focus on two numbers each month to know whether you are on track or falling behind. I’ll show you those two numbers below.

Before you get too excited, I need to reiterate this key point: if you want to succeed with zero-based budgeting, you still need to first create a Budget After Thinking. Otherwise, you won’t be able to figure out the key two numbers that you need to focus on.

This step is for those people who have already tracked their spending for at least three months, made thoughtful adjustments so their spending is in line with their values, and now know exactly how much fuel they can generate for their Later Money every month.

OK, so how does this all work?

I mentioned there are only two key numbers you’ll need to focus on each month:

  1. Your checking account cushion.
  2. Your Later Money transfer amount.

Let’s explore each number.

1. Your checking account cushion is your safety net.

A checking account cushion is the amount of money in your checking account that you don’t plan to spend. The purpose of the cushion is to give you a little breathing room so you can pay your bills, even if you overspend in one month.

Without the cushion, if you have a tough spending month, you either need to skip paying certain bills or skip making your Later Money transfer. Neither option is acceptable. The first option leads you into debt. The second option halts progress on your most important life goals.

The checking account cushion gives you protection.

How much of a checking account cushion do you need?

How much of a cushion do you need? It depends on whether you have consistent income (regular paychecks), or are paid inconsistently (commissions, freelance, contract, etc.)

If you are paid with consistent paychecks, I recommend your checking account cushion equal the amount you’ve planned to spend in your Now Money category from your Budget After Thinking (don’t worry, example below). This amount should give you a comfortable safety net without leaving too much money in your checking account that could be better used elsewhere.

If your pay is inconsistent, you’ll need a larger cushion to cover the larger gaps between pay days. I recommend you have double the amount of your Now Money. Note, you may have to tweak this amount based on your unique situation.

In our really lost boy example, he received paychecks biweekly. A good checking account cushion was $3,600 (equal to his Now Money).

This means that there should be $3,600 in his checking account to start each month. At the end of the month, after paying all of his bills and making his Later Money transfers, he should still have $3,600 left in his checking account. That’s his checking account cushion.

It’s OK if your checking account cushion temporarily dips below the amount you started the month with. This could happen during the time of the month when you pay certain bills, like your rent or mortgage. Don’t worry. The amount in your account will climb back up once you receive your next paycheck.

A final point: don’t spend this cushion. Fight the temptation to use your checking account cushion to pay off bills or debt. Without that safety net, zero-based budgeting does not work.

2. Your Later Money transfer is the main reason you’re budgeting in the first place.

This number reflects the whole purpose of budgeting in the first place: to create fuel for your ultimate goals in life. If you don’t know what your goals are, revisit our conversation on why you should want to be good with money. It all starts with what you truly want from your life and how you can use your money to get it.

When you’ve created your Budget After Thinking, you’ll know exactly what this amount is. In our really lost boy example, the total Later Money transfers added up to $2,050. In future posts, we will discuss where to transfer and what to do with this Later Money. No matter what, the goal is to put this money to work for you to progress towards your goals.

By focusing on just these two numbers, (1) your checking account cushion and (2) your Later Money transfer amount, you don’t have to track every penny. You’ll know if you are hitting your goals or falling behind just by looking at these numbers.

Now that we know the two key numbers to focus on, let’s see how this all works.

How to ensure you are on track with your money goals with just two numbers.

Sticking with our really lost boy, he predetermined that his checking account cushion is $3,600 and his Later Money transfer amount is $2,050.

At the start of the month, that means he had $3,600 in his checking account. Throughout the month, his checking account balance increased when he got paid (our really lost boy earned $7,500 per month). His checking account balance decreased whenever he paid for things like rent ($2,200) and any other bills.

The checking account cushion ensured that he had enough to cover all of his expenditures throughout the month. For example, if his rent was due on Wednesday, and he wasn’t getting paid until Friday, his checking account cushion ensured that he had enough in his account to pay the rent on time. His cushion might fall temporarily below $3,600, but his next paycheck would soon replenish his account.

As the month went on, various bills came due. Utilities may be due on the 7th of the month. Credit card bills on the 15th. These payments can all be automated so he didn’t have to actively worry about them. Again, his checking account cushion guaranteed he had enough in his checking account to pay them.

Towards the end of the month, in a perfect world, our really lost boy would have exactly $5,650 left after paying all of his bills. He could then transfer the predetermined $2,050 of Later Money to his various Later Money accounts. He’s then left with a checking account cushion of $3,600 and is ready to begin the next month.

This is not a “set it and forget it” budgeting method.

This is not a “set it and forget it” budgeting method. Think and Talk Money is all about exerting a little bit of mental energy on your money every week. This budgeting method is a good illustration of what that means. You don’t need to track every penny, but you still need to pay attention to your money choices.

To help you with that, I suggest that you glance at your banking or credit cards apps once a week to monitor your spending. If you use credit cards or electronic payments for most expenditures, it is quick and simple.

The reason it’s a good idea to glance at your banking apps is to make sure you are relatively close to your spending targets. If you notice that you’re overspending in the first half of the month, you can make the appropriate adjustments before the month ends.

This small amount of effort throughout the month is worth it. Every time you make that Later Money transfer at the end of the month, you’ll feel exactly what I mean.

Don’t strive for perfection.

I said above “in a perfect world” to highlight that we’re not striving for perfection. That’s an impossible standard. One month, our really lost boy might have only had $3,300 left after making his Later Money transfer. That’s fine. It’s a temporary blip that he could easily fix, if he’s honestly dedicated to his life goals. He had a couple of options.

His first option was to course correct the next month by spending $300 less. That could mean temporary adjustments in his Now Money or Life Money, such as skipping a couple dinners out, doing yoga at home, and buying chicken instead of steak at the grocery store.

His second option was to replenish his checking account cushion from his specific budget busters savings account. What is that, you ask? It’s a separate savings account to cover you if you have one of these higher-spending months so you can keep your money plan progressing.

In some months, you will actually underspend.

Where do you get the funds for such an account? Believe it or not, in some months, your spending will come in under budget. Let’s say our really lost boy had one of these good spending months in January. Maybe he did Dry January and ate all his meals at home for health reasons to compensate for all the holiday celebrations.

In this example, the result was he spent $500 less in January than he had budgeted for. Instead of leaving that $500 in his checking account (bringing his cushion up to $4,100) where it turns into disappearing dollars, he transferred it to his budget busters savings account.

Then, when he had a high spending month, he could make a transfer back into his checking account to keep his cushion at $3,600. All while continuing to make his Later Money transfers every month.

If you constantly run out of money before making your Later Money transfers, this method is not for you, yet.

Always remember the goal of your Budget After Thinking is to generate fuel for your life goals. If you’re not making these Later Money transfers, you’ve defeated the purpose of having a budget in the first place.

Don’t feel embarrassed or sad if that happens to you. Take it as a sign that you need to explore your Now Money and Life Money spending to see what adjustments you can make. Once you’ve found those adjustments, you can come right back to my version of zero-based budgeting.

If you want this plan to work, where you only need to focus on two numbers instead of tracking every penny, you need to be honest with yourself that you’re ready for this.

Decide for yourself what budgeting method works best for you.

If you’ve been successful tracking your spending in a spreadsheet or a budgeting app, and enjoy the process, you should continue to do so. If it ain’t broke, don’t fix it, right?

On the other hand, if you’ve created a Budget After Thinking and consistently hit your Later Money goals, you’re probably ready to stop tracking every penny, if you’d like.

To recap, my version of zero-based budgeting is for those people who want to continue to fuel their Later Money goals without the anxiety of the spreadsheet. Instead, focus on those two numbers: (1) your checking account cushion and (2) your Later Money transfers. This is what I’ve been doing for years and it has worked.

Happy boy with a bundle of money dollars cash who has a checking account cushion and Later Money.

If your cushion falls short one month, that’s OK. We are not striving for perfection. Make up for it the next month or use your budget buster savings account to replenish your checking account. And, keep making your Later Money transfers.

Has anyone else experienced mint.com anxiety? Are you currently using a budgeting app? How do you like it? Has any tried zero-based budgeting?
