Most spending decisions happen fast. You see something, you want it, you check the price, and if you can technically afford it, you buy it.
The problem is not the money. It is that a number like €500 does not mean anything on its own.
Is €500 a lot? It depends entirely on your income. But even monthly income is an abstraction. You do not feel income. You feel time.
The most honest way to think about any purchase is not in euros. It is in days of work.
Why Prices Feel Meaningless in Isolation
When you see a price tag, your brain has no automatic frame of reference. €400 for a weekend trip. €800 for a new phone. €120 for a jacket. These numbers exist in a vacuum.
Now try this framing instead:
“This phone costs me 12 working days.”
That lands differently. Suddenly you are weighing a purchase against something real: your time, your effort, the mornings and afternoons you traded to earn that money.
This is not a new idea. Economists call it the time cost of money. But it is rarely applied in practical, everyday decisions. Most people think in prices when they should be thinking in days.
The Formula
You need two numbers: your net daily income and the price of what you are considering.
Step 1. Find Your Net Daily Rate
Take your monthly net income (after taxes) and divide it by 22, the standard number of working days in a month.
Daily rate = Monthly net income / 22Using €1,400 net per month as a realistic EU baseline:
€1,400 / 22 = €63.60 per dayAll examples in this post use this same daily rate.
Step 2. Divide the Price
Work days = Price / Daily rateThat is the whole calculation. Apply it to any purchase in about five seconds.
Real Examples at €1,400 Net Monthly Income
A €300 Jacket → 4.7 days of work
€300 / €63.60 = 4.7 days. Nearly five full working days. Would you work a full week specifically to own this jacket? If yes, buy it. If that framing gives you pause, that pause is useful information.
A €500 Weekend Trip → 7.9 days of work
€500 / €63.60 = 7.9 days. Almost two working weeks. For some people, that is an obvious yes. For others, knowing it represents the entire first two weeks of their month changes the calculation.
A €1,200 Laptop → 18.9 days of work
€1,200 / €63.60 = 18.9 days. Nearly a full month of income. If you need it for work, it is probably still worth it. But comparing it to a €700 alternative (11 days) gives you a concrete way to weigh the difference.
A €60 Restaurant Dinner → 0.9 days of work
€60 / €63.60 = 0.9 days. Less than a full day. For most people, this is a completely fine trade. The point is not to make every expense feel heavy. It is to give larger purchases a proportional sense of weight.
When This Changes the Decision
This framework is most useful in the middle range: purchases between €150 and €2,000 that feel somewhat affordable but represent a real trade-off.
Common examples where converting to work days tends to produce a clearer answer:
- New tech (phone, headphones, camera, laptop)
- Clothing above a certain threshold
- Weekend trips or flights
- Furniture or home items
- Annual subscriptions billed upfront
The question is not "can I afford this?" That question is too easy to answer yes to. The better question is: "Is this worth X days of my life?" That one is harder to dismiss.
When It Does Not Apply
Some purchases do not fit this framework, and that is fine.
Experiences. A flight to see someone important, a concert you have waited years to attend. These do not reduce neatly to time-cost. Spend what feels right.
Urgent needs. A broken appliance, a car repair, a necessary medical expense. You need it, you buy it. The framework is not relevant here.
Gifts. The cost-to-days ratio for a gift carries different weight than a personal purchase. Context matters.
The formula is a tool for discretionary spending where the decision is not already obvious.
A Faster Way to Do This
If you want to skip the mental math, Easeful does this in a few seconds. You enter the price and your monthly income, and it converts the purchase into work days, percentage of monthly income, and impact on your financial safety buffer. No spreadsheet, no setup, no budget tracking required.
It is designed for exactly this kind of moment: you are about to buy something and want a fast, honest number before you decide. One input. One answer.
Key Takeaway
At €1,400 net per month, your working day is worth €63.60. That single number is enough to run a quick sanity check on almost any purchase.
Converting prices to work days will not make decisions for you. But it replaces the vague feeling of “is this too much?” with something you can actually reason about.
That tends to be enough.
