In the previous chapter you gathered all your spending into a list. But a list, however complete, isn’t yet a plan. For those numbers to be useful, you have to order them, and the most useful way is to classify each expense into one of three types: fixed, variable or small recurring. It sounds like accounting, but it’s the opposite: it’s the practical tool that tells you where you can act and where it isn’t even worth trying. Because each type of expense is tackled differently, and confusing them is a waste of time.
Why classifying changes everything
The reason many people fail at cutting is that they treat all expenses the same. They try to squeeze the rent (impossible this month), obsess over coffee (irrelevant), and don’t touch the subscription that renews itself (the real leak). They’re fighting on the wrong fronts.
Classifying solves this. When you know which expenses are fixed, which variable and which small recurring, you immediately know where your room to manoeuvre is. Fixed ones are hard to move but, when you do move them, the saving is large and permanent. Variable ones are where you have daily control. Small recurring ones are tiny but, added up, surprising. Each calls for a different strategy. Let’s go one by one.
Fixed expenses
Fixed expenses are the ones you pay regularly and for a similar amount each month, whether you like it or not: rent or mortgage, basic utilities (electricity, water, gas, internet), insurance, loan payments, recurring taxes, the subscriptions you actually use.
Their key trait is that they’re predictable and committed. You know they’ll come and for how much. That makes them, at once, the stable base of your budget and its heaviest part: they’re usually the biggest slice of what you spend.
The trap with fixed expenses is that they seem untouchable, so most people don’t even look at them. Mistake. It’s true you can’t change them this month — your rent is what it is — but you can review them periodically, and that’s where the big saving lives. Renegotiating the mortgage, switching electricity provider, checking whether that insurance has coverage you don’t need, cancelling an expensive subscription. A single good decision on a fixed expense saves every month, with no ongoing effort. That’s why, even though they’re the hardest to touch, they’re the most rewarding when you manage it.
Variable expenses
Variable expenses change from month to month depending on your decisions: the grocery shop, fuel, leisure, clothes, eating out, treats. They’re not committed in advance; they depend largely on what you decide day to day.
This is where you have the most immediate control, and where most people concentrate (rightly) their adjustments. One month you can spend more on restaurants and another less; you can shop more deliberately or less. Flexibility is the advantage.
But watch two things. First: within variable expenses there are needs (food) and wants (eating out), and it’s worth not confusing them when cutting. Squeezing basic food to keep your leisure is rarely a good idea. Second: variable expenses are the ones that most get out of control when you don’t look, precisely because they depend on impulsive decisions. Keeping them watched — not banned, watched — is where the day-to-day is won.
Small recurring expenses
Small recurring expenses are the little outlays, almost always variable, that individually seem not to matter but, repeated, eat an enormous part of your money: the daily coffee, the water you buy out, the micro-purchases on your phone, the kiosk treat, the latest app.
They’re “small recurring” because each is tiny, but together they carry an enormous weight. A €1.80 coffee a day is over €650 a year. Three small daily treats can easily exceed what you pay for electricity. The problem is that, being small, they escape the radar: nobody feels they’re “spending money” when paying €2.
The way to tame them isn’t to ban them — that breeds frustration and lasts a short while — but to make them visible. The moment you see those coffees add up to €650 a year, you decide with information: maybe you love coffee and keep it, but perhaps you discover that half were out of inertia, not pleasure. The key tool here is translating the small into its annual cost, where its true size shows. (For this, the Expense to Life-Hours Converter does exactly this work of revealing the real cost of the everyday.)
How to tackle each type
With the classification done, you have a clear strategy for each front, and that’s what turns the list into a plan:
Fixed: review them periodically, not daily. There’s no point looking at them every week. But once or twice a year, sit down to renegotiate, compare and cut what no longer adds value. It’s the highest-impact saving per hour invested.
Variable: watch them in the present. Here ongoing awareness does help. Not prohibition, but attention: knowing how much you’ve spent this month in each category lets you adjust in time, before the month goes off track.
Small recurring: make them visible and decide. Don’t chase them with guilt. Bring them to light, look at their annual cost, and keep the ones you genuinely enjoy while cutting the ones of pure inertia. That’s usually where a painless and surprising saving lives.
An important note for the whole course: classifying isn’t cutting. Classifying is understanding. There will be expenses that, seen clearly, you’ll decide to keep exactly as they are because they bring you value, and that’s perfectly fine. The goal is never to spend as little as possible, but to spend intentionally: putting money where it truly matters to you and pulling it back from where it only slips away.
You now have your money in order and you understand how each type of expense behaves. With that solid base, in the next block we build what gives the course its name: a realistic family budget, with a method for splitting your money that you can actually follow month after month.
