Latest / Budgeting for Beginners with Fexingo: Cash Envelopes, Apps, and Simple Money Tracking / How to Budget When Your Income Changes Every Month
Transcript
- Lucas: So you're a freelancer, a gig worker, or maybe you're in sales on straight commission. Your income looks different every month. And every budgeting guide you've ever read starts with 'know your monthly income' — which is kind of useless advice when that number is anything but fixed. Luna: Right. The standard 50-30-20 rule or even the envelope system assumes a steady paycheck. If you're dealing with variable income, those systems can actually make you feel worse. Lucas: Exactly. Today I want to walk through a specific strategy I call the 'zero-based envelope method' for variable income. It's built around a single number — your baseline — and a single rule: you never budget money you haven't earned yet. Luna: Let me guess — the baseline is your lowest realistic month. Like the floor. Lucas: Exactly. Let's say you're a freelance graphic designer and your monthly income over the past year ranged from about $2,000 to $5,000. Your baseline is $2,000. That's the number you build your core budget around — rent, utilities, groceries, minimum debt payments. Everything that has to get paid no matter what. Luna: And what happens in the months you earn $4,000 or $5,000? You've got a surplus. Lucas: That surplus goes into two buckets: first, a buffer fund to top up future lean months. Second, discretionary or goal spending that you allocate using cash envelopes. The key is that you only create envelopes when the cash is actually in hand. Luna: So you're not pre-allocating money you hope to earn. You're reacting to what you actually have. That feels a lot more honest. Lucas: It takes the anxiety out of budgeting because you're never playing catch-up. Let me give you a concrete example. Say your baseline $2,000 covers $1,400 in fixed costs — rent, utilities, phone, minimum debt payments. That leaves $600 for variable essentials like groceries and gas. With the cash envelope system, you'd pull out, say, $300 for groceries in cash at the start of the month and keep it in a labeled envelope. Luna: And if you have a $4,000 month, you've got an extra $2,000 above baseline. You might put $1,000 into a buffer fund — maybe a high-yield savings account — and then create new envelopes with the remaining $1,000. Like a 'dining out' envelope with $200, an 'entertainment' envelope with $100, and a 'savings goal' envelope for a trip or an emergency fund. Lucas: Exactly. The envelopes are physical or digital — whatever works. But the discipline is the same: you spend only what's in the envelope. When the cash is gone, you stop. For variable income folks, that's a lifesaver because it prevents lifestyle creep in high-earning months. Luna: I love that. So the buffer fund is really the backbone. How much should someone aim to have in there? Lucas: I'd recommend three to six months of baseline expenses. So for our designer, that's $6,000 to $12,000. It takes time to build, but every surplus month you contribute to it. And once it's funded, you can redirect those surplus dollars to other goals — retirement, a down payment, whatever. Luna: That's a big ask for someone just starting out. Is there a way to start smaller? Lucas: Absolutely. Start with a one-month buffer — just $2,000. That alone smooths out the worst of the volatility. And you can use a digital tool like YNAB, which is built for this. YNAB's whole philosophy is 'give every dollar a job' — but only dollars you actually have. It forces you to work with your baseline, not your aspirational income. Luna: And EveryDollar has a version of that too, right? The 'zero-based' approach. Lucas: Yes, but YNAB is more explicit about handling variable income because it treats your budget as a rolling pool. EveryDollar is more month-by-month, which can still work if you're disciplined about not budgeting future income. The envelope method I'm describing is really just a physical version of that digital logic. Luna: So bottom line — if I'm a freelancer listening right now, what's the one thing you want me to do this week? Lucas: Figure out your baseline. Go back through your last 12 months of income, find the lowest month, and that's your number. Then build your core budget around that. Anything above baseline is bonus money that gets allocated only when it arrives. That one shift — from budgeting on hope to budgeting on reality — changes everything. Luna: And if you want to try the cash envelope part, just start with one category — like groceries. Pull out your baseline amount in cash, put it in an envelope, and see how it feels. It's a low-risk experiment. Lucas: Great advice. And speaking of experiments, you know, this show is possible because of listeners who find value in these conversations and choose to support us. If our money talks have helped you rethink a budget or tackle a tricky financial decision, you can buy us a coffee — literally — at buy me a coffee dot com slash fexingo. That support keeps the podcast ad-free and focused on practical, no-fluff content. Luna: Yeah, it really does make a difference. We keep it simple because it works. And every little bit helps us keep doing what we love. Lucas: So back to the variable income strategy — the last piece I want to mention is the 'lean month' plan. What do you do when you hit a $2,000 month and the buffer isn't fully built yet? You've got to cut variable spending to the bone. That's where the envelope system shines: you can literally see that you only have, say, $50 left for groceries for the week. It forces creativity and prioritization. Luna: And it beats the stress of swiping a card and hoping it works out. There's something calming about knowing exactly how much you have. Lucas: Exactly. The goal isn't perfection. It's just a system that reduces the noise so you can focus on earning more and spending smarter.
