ADRIMYour home is a business: income, costs and profit
We live surrounded by businesses that run on numbers. The bakery on the corner knows what each loaf costs to make and what it sells for. The café knows which months cover its costs and which ones lose money. Even the dentist's practice works out how many patients a day it needs to pay the rent and the salaries.
All of them decide with one question in front of them: can I afford this? At home, the question is usually a different one: do I deserve this? A trip because it has been a hard year. A new phone because the old one is slow. Dinner out because it's Friday. These are emotional, impulsive decisions, and most of the time nobody looks at the numbers until the end of the month.
You don't need to become an accountant. You just need to ask the same three questions any business asks: how much comes in, how much goes out, and how much is left.
Why it matters more than ever
Switzerland came through the inflation of recent years better than most of Europe, but it did not come through untouched. According to the OECD, real wages are still below their 2021 level in nine European countries, Switzerland among them, with a slight decline of between 0.7 % and 1.4 % (Euronews, OECD Employment Outlook 2026). The Federal Statistical Office tells the same story: even after real wages rose 1.6 % in 2025, the real wage index stood at 99.2 points, still below its 2020 level of 100 (FSO, 21 April 2026).
Meanwhile one fixed cost keeps climbing. Compulsory health insurance premiums will rise by 5 % on average in 2027, to CHF 487.60 a month for an adult, CHF 22.80 more than this year (swissinfo.ch, with FOPH figures). For a couple, that is almost CHF 550 more a year before anyone has been to the doctor.
Housing makes it even more visible. To buy, Swiss banks usually expect 20 % of the price in your own funds, at least half of it in savings rather than pension money, and they check that housing costs stay below one third of gross income at a notional interest rate of 5 % (UBS). Those rules leave no room for guesswork.
When the margin gets tighter, improvising gets expensive. What used to be absorbed without thinking now shows up at the end of the month.
Your household's income statement
A business sums up its year in a single statement: income minus costs equals profit. Your home works exactly the same way; only the names change.
| In a business | In your home | Examples |
|---|---|---|
| Income | What comes in each month | Your salary, your partner's, a 13th month, a bonus, rental income |
| Fixed costs | What you pay even if you do nothing | Rent or mortgage, health insurance premiums, Serafe fee, phone and internet, public transport pass |
| Variable costs | What depends on your choices | Groceries, eating out, clothes, leisure |
| Provisions | Costs you know are coming | Income tax (if it isn't deducted from your salary), your health insurance deductible, holidays, car service, Christmas presents |
| Profit | What is left: your savings | Emergency fund, pillar 3a, deposit for a flat, investments |
Two ideas change the way you look at money. First: savings are not what is left over, they are the profit, and they come out at the start of the month, not the end. Second: provisions prevent nasty surprises. In Switzerland most residents pay income tax in one or a few bills rather than through their payslip; a CHF 8,400 tax bill is CHF 700 a month, not a hole in the spring. The same goes for holidays: CHF 3,000 is CHF 250 a month, not a shock in July.
The decisions that become clear
With the statement in front of you, the big questions stop being a hunch. Take an example household: CHF 9,000 net comes in each month (about CHF 130,000 gross a year), the cost of living is CHF 7,800, and CHF 1,200 is left as profit.
- Can we afford this trip? A CHF 3,600 trip is three months of profit. The question stops being “do we deserve it?” and becomes “what do we stop saving to pay for it?”.
- What about the new car? A CHF 600 monthly lease eats 50 % of the profit for years. No business would sign up for a fixed cost like that without first looking at its margin.
- Do we go out too much? If eating out rises from CHF 300 to CHF 500 a month, profit falls by 17 %. You don't have to stop going out, just know what it costs.
- When will we have the deposit for a flat? For a CHF 900,000 flat, the bank wants CHF 180,000 of your own funds, and at least CHF 90,000 of that must be savings, not pension money. At CHF 1,200 a month, the savings part alone takes just over six years. The affordability test matters even more: at the bank's notional 5 % rate, plus 1 % for upkeep and the repayment of the second mortgage over 15 years, that flat costs about CHF 53,000 a year, which needs a gross income of around CHF 159,000. Our household could afford about CHF 730,000. That calculation turns a dream into a plan with a price and a date.
- Does my salary support my lifestyle? A business that loses money three months in a row doesn't wait for the fourth: it raises prices or cuts costs. Your home is no different. If the cost of living keeps exceeding income, it is time to cut back, ask for a raise, find extra income or change jobs. And with several months of figures in hand, that conversation with your employer rests on data, not on feelings.
Where the metaphor stops
A home is not just a business, and it is worth saying so. A business exists to make money; a home exists to live well. Some costs produce no “profit” and are worth every franc: your health, your children's education, helping your family, a holiday you really need.
Thinking like a business doesn't mean cutting everything. It means deciding with the numbers in front of you: spending on what matters to you, knowing what it costs, instead of finding out at the end of the month.
How to start this month
- Write down what comes in. All household income, net, as it lands in the account.
- Set the profit aside on day one. Pick an amount, even a small one, and move it to another account as soon as you are paid. Put the tax provision aside too. What remains is what you can spend.
- Track every expense for a month. No judging. At the end of the month you will know which costs are fixed, which depend on you, and where the money slips away.
With one month of data you have your first income statement. With three, you see the trend. And with a year, you know exactly what you can afford.
