How do you budget with an irregular income?

Last week, a number of you mentioned a major difficulty in setting up monthly household budgets: irregular incomes. What do you do when you’re self-employed and have a fluctuating income? What if you’re paid on commission? Or what if your income simply varies depending on the time of year?

I don’t pretend to think this is easy, but there are some solutions for you. I’d recommend trying them before brushing off budgeting all together. They may not be pure zero-based budgets, but pulling some ideas from these methods could morph into a custom zero-based hybrid budget for your family.

The “Live This Month on Last Month’s Money” Idea

Like Maureen suggested, you can employ the method of paying your current month’s expenses with last month’s income. In other words, you’d pay for the July phone bill with June’s paycheck. If you have an irregular income, this would give you a month’s leeway, and you could either find ways to supplement an upcoming month when finances are tight, or you could plan on simply living frugally for a month.

The obvious question to this, then, is how do you start? Because in that first month of trying this plan, you’ve got to have some money from somewhere. I know it can work, but I think you have to slowly work up to this system, saving a little each month until you have a month’s worth of expenses in savings ready for you.

The “60% Solution”

There’s also an idea called the 60% Solution. This was developed by Richard Jenkins at MSN Money, and in a nutshell, he advocates diving your gross monthly income as follows:

  • 60% to committed expenses – everything from regular bills to clothing to giving.
  • 10% to retirement
  • 10% to irregular expenses – vacations, major purchases, and the like.
  • 10% to long-term savings or debt – either one, depending on your situation.
  • 10% towards fun – entertainment, hobbies, etc.

I suppose this could work for some people, but I don’t feel I can completely endorse this idea because of my firm conviction on being debt-free. If you’re in debt, I advocate doing everything you can to become debt-free, even if that means putting 50% of your income towards knocking it out (for a short time). But if you are debt-free, this budgeting idea could reasonably work for you.

If we had an irregular income, however, this is how I would budget.

The “How I Would Budget if I Had an Irregular Income” idea

• Category 1. Instead of starting with our income, like you do in a zero-based budget, I’d first list out our predictable, committed monthly expenses. This is stuff like rent, utilities, and groceries. This is not stuff like dining out, entertainment, or vacation. Ask yourself, what do you absolutely have to pay for in order to survive? Those are the items to list here.

• Category 2. I’d then list out our more irregular annual expenses (such as Christmas, or sometimes auto insurance), divide them by 12, and use that number as our monthly expense for that category.

• Category 3. Then, I’d list our monthly “fun” expenses, like dining out, hobbies, or entertainment, and decide how much we want to spend on this month.

• Category 4. Finally, I’d list our nice-but-unnecessary expenses (like if we’re saving for a new couch), add up the total amount we want saved, and divide by 12.

Category 1 is our necessary expenses, and that total amount should go into everyday our checking account. Categories 2, 3, and 4 would then fall into separate checking or savings accounts, dog-eared for their specific purpose (sinking funds, in other words).

Our goal would be to fully fund Category 1 each month. After that, with this plan, you decide based on your situation which other categories fall in order of importance. So if it were us, I’d then fund Category 2, then 3, and finally 4.

This is when the beautiful magic of Capital One 360 accounts come into play – you can have an unlimited amount of accounts, label them for their specific purpose, and have money automatically drafted into each account.

I’ll play this out with our token family. The McSimples made $3,000 in June, but only $2,300 in July.

The McSimple’s Typical Monthly Expenses:

    • C1 – giving: $100
    • C1 – rent: $1,000
    • C1 – utilities: $300
    • C1 – groceries: $500
    • C1 – gas: $100
    • C1 – other monthly bills: $200
    • C2 – auto insurance: $50
    • C2 – Christmas: $50
    • C2 – gifts: $100
    • C3 – entertainment: $200
    • C3 – stamp collecting: $100
    • C4 – vacation: $200
    • C4 – saving for a new couch: $100

TOTAL = $3,000

For June, The McSimples could fully fund all four categories, but in July, they could only fund Category 1 and part of Category 2. Though not ideal, it’s okay, because Category 1 is what they need for survival.

This idea works well following the Baby Steps. For example, if you were on Baby Step 2 and working on becoming debt-free, anything but C1 and C2 would go to the Debt Snowball. If you’re working on fully-funding your savings with 3-6 months of expenses, as in Baby Step 3, then I’d say anything past C3 goes into your Emergency Fund.

Now I’m not a financial expert. Does anyone else have ideas? Have you had personal success budgeting on an irregular income? Let’s give those Simple Mom readers with unpredictable incomes some ideas! I’m convinced that everyone is able to responsibly steward all the money that comes their way, no matter how often it’s given to them.

    I’m going to work through the “holding account” scenario described in your link to My Dollar Plan and see how that works out for us. Part of my problem is that I’ve been keeping our household expenses and hubby’s business expenses intermingled. Today I worked on clearly defining the two entities. Now I have a clear grasp of how much the household needs to survive and how much the business needs to survive. It clarifies the goal of how much hubby needs to earn in order for home and business to stay in the black.

  2. Journeyer

    I think you’ve hit the nail on the head. The non-discretionary items MUST be taken care of before anything else.

    The only other thing I would suggest is to ensure that you do Baby Step 1: Make a $1,000 emergency fund. While not strictly it’s purpose, I think if you’re on an irregular income this could be used as a buffer for the times when bills are more than usual or your income is much lower than expected. For example your gas bill might be a bit higher than usual because of a cold snap or something.

    @Jill – I’ve heard from small business owners that it makes a world of difference to have two separate accounts for personal and business. Yeah, the holding account scenario was a new one for me, too – sounds interesting, though. Let me know if you try it!

    @Journeyer – Well said. Another reason why the idea works well with the Baby Steps!

    One way we’ve adapted to an irregular income is by making our basic $1000 emergency fund into a $1000 emergency fund and $2000 budget shortfall fund – that way when our income doesn’t fit the budget for a particular month we simply pull it out of the budget shortfall fund and then the next months top priority, after essentials, is to replenish that shortfall fund

    One of the things newcomers to fluctuating income have to deal with is the urge to spend money when you have it. DON’T. 😀
    Fluctuating incomes often means fluctuating *spending*. Keep your spending habits at an average rate, regardless of what’s coming it. Doesn’t matter what you call the excess during more solvent times. Resist the urge to spend it on things you’ve “gone without” just to “treat” yourself.

    I live in an area where lobster fishermen can earn a full year’s income in a few months. But then that’s it. The danger is forgetting it has to last all year, not just four months.

    My husband is a self-employed contractor. It’s feast or famine. Thankfully, the last few years have been feast. However, the feast brought us out of a not just a famine, but a severe famine. I think we were in denial as to how bad it was . Anyway, during that severe famine for the first time in his 13 years of being in business, we were unable to draw a paycheck. For 3 weeks we had no pay. It was a real eye opener for us, and you learn real quick what is *necessary* and what is not! I cried many times during those days, but the lessons I learned were invaluable! With the rising costs of it seems everything, I’m again considering more carefully what is a need and what is a want.

    You had some great ideas in this post. Luckily we have a fixed paycheck, so our budget is pretty cut and dry. But, if we ever go to an irregular income, I’ll remember these ideas. One thing my parents always taught me, is to put 10 percent of my income aside in savings. This advice has been invaluable for those times when we have unexpected expenses arise.

    @Blessed – I like that idea! I guess you just have to make sure you have plenty in your shortfall fund, and replenish when it goes down, like you said.

    @Andrea – Well said!

    @Kat – Sounds like you learned invaluable lessons there. God truly does care about our character-building!

    @Kori – 10% is always a good rule of thumb. It’s longstanding advice for a reason, I guess!

    This is exactly what I’d been hoping for. I think the “live this month on last month’s paycheck” would probably work best for us, but you’re right — saving up to start will take us some time. But I also live every day with the belief that I am growing “wealthier and wealthier every day in every way”, so this system will help us to grow while still maintaining a solid budget system that stops us from overspending when we have a earn more than we did the month before.

    This is the situation the husband and I are in, we have a irregular income. Only one part of our income do we know the exact amount for each month. His shifts constantly change as well as his hours. He may work 40 hours for three weeks of the month, then the last week he may work 45 (5 hours of over time) or 30. It is very difficult to budget on an irregular income, that is why we pay our rent with what we know is the secured income, what will not change.

    I really like your category idea and may have to try and implement that into my budgeting.

    This is completely off topic, but wanted to let you know anyway – I received my order today with my Dave Ramsey books in it! After reading all you posts on money management, I couldn’t wait to buy the books and get started straight away… BUT I had to wait for Amazon to deliver my books all the way to Australia for that 😀
    July is going to be a huge month for our little family! With these books and the Pear Budget (it’s awesome – so simple!) I can’t wait to begin our new financial year on a budgeting high :o)
    Thanks for all your inspiration and more importantly, motivation!

    @Meegan – That’s not off-topic at all! I’m so happy for you and your family! Thanks for your kind words.

  13. Thora

    My husband is in Graduate School, and so on a tight, irregular budget I’ve found a build-up budget to be invaluable. It’s like a zero based budget, but I add up all the necessaries, like rent, utilities, food, tithing (0r giving, as you put it), etc, and then based on how much we usually have I assign the rest. If our utilities are a little under budget, I automatically save that amount (along with food, or any other variable expense), and so a buffer builds up for when we have a month with less income. This isn’t part of our long term savings, but rather a small predictable-need fund. Because our income is variable, but not by huge amounts, this smooths every month over.

    Great post, fabulous advice. As a good amount of your readers, we are dealing with fluctuating income as well. We bought our home right before the housing market tumbled and have been struggling ever since. My husband is ex-military turned car-salesman and when he first started a few years ago he would bring home nice paychecks. We were able to put away money into savings and used it for our down payment. I quit college (again) to bring in some money for our new expenses (eg. home insurance, larger utility bills) but was laid off this past February and haven’t been able to get a job ever since. We nearly lost our home, not having been able to make the mortgage payments, until our finance company renegotiated our mortgage. That was two months ago, today, with my husband now bringing home paychecks around $200 each week, we can barely keep afloat. The car business has gone dead, jobs are hard to come by and me being a permanent residence has not aided in my job search either. Tears are rolling down my face reading your and your readers’ advice, not having a way of implementing them is heartbreaking.

    Thank you though for being a beacon of light, thank you for all your advice, tips and encouragement you offer on your website. I’m a newbie to your site and am going through your posts one by one, taking babysteps in applying your techniques to our life. Keep up the great work you do.

    Thank you, Thank you, Thank you. I’ve had Ramsey’s printouts and think they are great but with irregular income or no income at times I have not been able to get my head around a very simple budget and savings plan. I have only heard a little about ING but will be looking seriously into what it has to offer our family. Sometimes envelopes are just too easy to “borrow” from. Our bank doesn’t offer a great savings interest either. I am excited to have separate savings labels too. You have really helped me see a simple way (categories) and when paychecks, invoices or extra comes our way to go down the list and put it where it is needed.

  16. Amber

    I have a VERY irregular income, and I combine two of your budget ideas; I live on last month’s income, and from that I spend for necessities first. It’s what works best for me.

    You’re the first person I’ve seen write about budgeting on a varying income; it’s a blank space that’s in need of discussion. Thanks for bringing it up and for the good ideas!

    P.S. I second the recommendation for ING Direct. …Though the interest rates were much higher when I first started with them. 🙂

    Hello Tsh,
    Nice thoughts on a question that is really hitting a lot of people right now. Especially people that are having their hours cut back or being layed off. Many of them are starting businesses to try and make extra income.

    As far as the technique of spending the money that you made in the last month, another major drawback to having to get a month ahead to start is that you will essentially have to create a new zero based budget every money to account for the actual money available. This is a tedious task and not one that most people will keep up with for very long.

    Your suggestion on how to organize your expenses so that the least important expenses will fluctuate with your income is very insightful and I think a more appropriate solution than simply trying to budget based on past performance.
