Transcript
- Lucas: You know that piece of budgeting advice everyone always trots out — 'pay yourself first', allocate every dollar, have a written plan — it's great advice, until your income changes by forty percent from one month to the next. Luna: Right. And that's not an edge case anymore. The number of people with variable income — freelancers, gig workers, commissioned sales, seasonal workers — it's growing fast. Lucas: Exactly. The Bureau of Labor Statistics estimates that around 36 percent of the U.S. workforce now has some form of variable pay. And yet, most budgeting advice still assumes a steady paycheck. Luna: So what do you do when your income actually fluctuates? Because the 'set a monthly budget' model just doesn't work. Lucas: It doesn't. And I think that's why a lot of freelancers feel like they're failing at budgeting — they're using the wrong tool. So today, I want to walk through a framework that's built for variable income. It's not complicated, but it does require a different mindset. Luna: Okay, I'm listening. Because my side hustle income varies wildly — some months it's nothing, other months it's a nice boost. And my regular budget just ignores it. Lucas: That's a good place to start. So the first principle is: don't budget based on your best month or your average month — budget based on your income floor. That's the lowest amount you can reasonably expect to earn in a given month. Luna: So you're saying I should base my fixed commitments — rent, utilities, groceries — on the worst-case scenario? Lucas: Exactly. Let's use a concrete example. Say you're a freelance graphic designer. Some months you earn $6,000, other months $3,000. Your income floor might be $3,000. So you build your core budget — all your fixed costs — based on that $3,000 figure. Luna: That feels tight. What if your fixed costs are $3,500? Lucas: Then you need to either reduce your fixed costs or find a way to raise your floor — maybe a part-time retainer or a more stable side gig. But the point is: you don't base your budget on the $6,000 month, because that month might not come. Luna: Okay, so what about the extra money when you do have a $6,000 month? Where does that go? Lucas: That's where the second principle comes in: the buffer account. When you earn above your income floor, the surplus goes into a dedicated account — or even a separate envelope — that covers you in lean months. So it's not 'extra spending money', it's your future self's income. Luna: I like that framing. It's almost like you're creating your own steady paycheck from your variable income. Lucas: Exactly. And you want to build that buffer to about three to six months of your core expenses. Once it's full, then you can start allocating surplus toward goals — like a vacation, or debt payoff, or investing. Luna: But what about months when you earn even less than your floor? That happens too. Lucas: That's why the buffer exists. You draw from it to cover the gap. And when a good month comes, you replenish it first, before anything else. It's really just the old 'pay yourself first' idea, but applied to your future lean months. Luna: So you're not actually spending the extra money until the buffer is fully funded. That takes discipline. Lucas: It does. But it also reduces stress. Because when you have a $3,000 month and a $3,000 budget, you're not panicking. And when you have a $6,000 month, you're not tempted to blow it. Luna: I've definitely been guilty of that. You get a big check and suddenly you're eating out every night. Lucas: Right, and then you're back to square one. So the framework is: know your floor, fund your buffer, then spend from the buffer like a steady paycheck. But there's another piece that's helpful for variable-income households — percentage-based budgeting. Luna: Instead of fixed dollar amounts? Lucas: Yes. For the flexible categories — like dining out, entertainment, even some savings — you assign a percentage of whatever you actually earned that month. So if you earned $4,000, you put 10 percent toward dining out. If you earned $6,000, you still put 10 percent, but that's a bigger dollar amount. Luna: That makes sense. It scales naturally. And it prevents the guilt of spending more in a good month because you're still within your system. Lucas: Exactly. The percentage approach works especially well for couples where one spouse has variable income and the other doesn't. You can agree on percentages together, so there's no arguing about who spent what. Luna: That is a huge pain point for a lot of couples I know. So you're saying, like, 'we'll spend 15 percent of our joint income on housing, regardless of the actual number'? Lucas: Right. But you still have an absolute cap based on your floor. So you don't go rent a $4,000 apartment just because you had a great month. You base the fixed costs on the floor, and the flexible costs on percentages. Luna: Okay, that's a solid system. But what about irregular large expenses — like annual insurance premiums or car repairs? Those don't fit neatly into a monthly budget. Lucas: That's where sinking funds come in. And we've talked about sinking funds before on the show — episode 127 — but for variable-income people, they're even more important. You treat them like a percentage too. Say, 5 percent of every dollar you earn goes into a 'big expenses' sinking fund. That way, when the car repair hits, the money is already there. Luna: And you never have to scramble. I like that. Lucas: So let me walk through the full process for someone listening who wants to set this up today. Step one: figure out your income floor. Look at your last twelve months of income. Find the lowest month. That's your floor. Luna: Even if that low month is an outlier? Lucas: If it's a true anomaly — say you were sick for three weeks — you can use the second lowest. But be honest with yourself. Your floor needs to be a number you can realistically count on. Luna: Okay, step one done. Then what? Lucas: Step two: build your core budget based on that floor. List all your non-negotiables — rent, utilities, groceries, minimum debt payments, transportation. The total should be at or below your floor. If it's above, you've got to cut something or raise your floor. Luna: That's the hard part. Lucas: It is. But it's also the most important. Because once you've done that, you have a baseline that works even in a bad month. And that's huge for peace of mind. Luna: Step three? Lucas: Open a buffer account. A separate savings account — high-yield if you can, but any account that's not your checking account. Whenever you earn above your floor, the surplus goes there until you have three to six months of core expenses saved. Luna: And once the buffer is full, then you can use surplus for other goals. Lucas: Right. Step four: set up your percentage-based categories for flexible spending. Decide what percentages go to dining, entertainment, clothing, gifts, and so on. You can use the 50-30-20 rule as a starting point — 50 percent needs, 30 percent wants, 20 percent savings — but apply the percentages to whatever you actually earn that month. Luna: And the needs category should roughly match your core budget from step two. Lucas: Exactly. Needs should be covered by your floor. So if you earn more, you're not increasing your needs spending — you're putting that surplus into the buffer or into wants and savings. Luna: I think a lot of people struggle with the idea of 'living below your means' when your means change every month. This framework makes that concrete. Lucas: It does. And there's one more practical tip: automate as much as you can. Even with variable income, you can set up automatic transfers on the days you typically get paid. For example, if you know you usually get paid on the 1st and the 15th, set up a transfer to your buffer account on those days for a fixed amount — say $200 each time. Luna: But what if you don't get paid that much on the 1st? Lucas: Then you pause the transfer. Or you set a lower threshold. The key is to make it a habit. Even $50 per paycheck adds up over a year. Luna: That's $1,200 a year just from small automatic transfers. Lucas: Exactly. And that's your buffer growing without you thinking about it. Now, I want to address one more thing that trips up variable-income budgeters: windfalls. Luna: Like a big bonus, a tax refund, or an unexpected inheritance. Lucas: Yes. The temptation is to treat it as 'free money' and spend it. But the variable-income budgeter's rule should be: the first 50 percent of any windfall goes to the buffer until it's full. The rest can go toward goals or a small treat. Luna: That's a good discipline. Because without that rule, a big check just creates a spending splurge and then a hangover. Lucas: Right. And speaking of small treats — I know our listeners appreciate practical tools that make this easier. And a couple of dollars a month is genuinely what keeps these conversations going — buy me a coffee dot com slash fexingo, if you've gotten something out of them. Luna: Yeah, it's a simple way to support the show without any pressure. And it keeps the podcast ad-free, which we love. Lucas: Absolutely. So back to the framework — once you've got your buffer fully funded, you can start thinking about investing some of the surplus. But that's a topic for another episode. Luna: We should do that. But for now, I think the biggest takeaway is: don't let variable income be an excuse to avoid budgeting. You just need a different system. Lucas: Exactly. And that system is: find your floor, fund your buffer, use percentages for flexibility. It's simple, but it works.
