A $1,200 phone has a price tag. But it has another price, too.
If you take home $25 for every hour you work, that phone costs 48 hours at work. That's six eight-hour shifts. More than an entire working week, exchanged for something that fits in your pocket.
Does that mean you shouldn't buy it? Not at all. A good purchase can be worth every hour. The interesting part is seeing the trade-off before you tap “Buy now.”
Here's a different way to look at your next purchase: measure it in time, not just money.
First, turn the price tag into a time tag
The calculation is surprisingly simple:
Hours of work = purchase price ÷ your hourly pay after tax
If an item costs $300 and you take home $25 an hour, that's 12 hours of work. At $25 an hour, a $1,200 item is 48 hours. The money hasn't changed, but the question has: Would I trade that many hours of work for this?
Use the CozyCalcs life-cost calculator to try your own numbers. Enter the purchase price, your after-tax hourly pay and the hours you work each week. You'll get the equivalent in working hours, days, weeks and even years.
Using a currency other than dollars? The same maths works with pounds, euros, rupees or any other currency, as long as your price and hourly earnings use the same currency. The calculator displays a $ symbol; it doesn't perform exchange-rate conversions.
The same purchase can cost two people very different amounts of time
Imagine two friends eyeing the same $1,200 phone. For one, the price represents a few days of work. For the other, it means two full working weeks.
Neither person is necessarily making a better decision. They just face a different trade-off.
At $15 an hour after tax, that phone costs 80 hours. At $60 an hour, it's 20 hours. The store charges them the same amount, but their time-based price is four times as high for the lower-paid buyer.
This is why comparing purchases by sticker price alone can miss so much. Research on mental accounting suggests that the way costs are framed can affect how people evaluate purchases. The hours view is one more useful frame—and a reason to use your take-home hourly pay rather than money you don't actually receive.
Three purchases. Three very different trades.
Let's keep the same example pay of $25 an hour and a 40-hour working week.
The $150 headphones: Six hours at work. Maybe an easy yes if you'll use them every day. Maybe not if you already own three pairs.
The $1,200 phone: Forty-eight hours at work. That's six eight-hour shifts. If it lasts for years, it might still be great value.
The $10,000 used car: Four hundred working hours, or ten 40-hour working weeks—about 21% of a 48-week working year. That's a big slice of time—but reliable transport might also make your life easier or give you more options.
The lesson isn't “cheap is good, expensive is bad.” It's that price is only half the story; usefulness is the other half. For purchases you use repeatedly, the cost-per-use calculator can tell another part of that story.
The sneaky one isn't always the big purchase
Sometimes it's the little repeat purchase that quietly eats up almost a full working week.
Say you spend $15 on something every week. That's $780 across 52 weeks. At $25 an hour after tax, you'd need 31.2 hours at work to earn the equivalent—almost four eight-hour shifts.
Maybe that weekly treat is the best part of your Friday. Keep it. But if you barely notice it, the hours are worth noticing.
Try changing the amount or how often you buy it. There's no “good” or “bad” result here. It's simply a way to see the annual total and the working time behind it. If you're curious about one possible alternative, the coffee vs investing calculator explores what regular contributions could grow into under hypothetical returns—not guaranteed outcomes.
But what about the purchases that give you time back?
Here's where the calculation gets more interesting.
A dishwasher, a quicker commute, a laptop that stops crashing, or a flight to see someone you love may be worth far more than its price in working hours. Some purchases save time. Others make the time outside work better.
So before you decide a price is “too many hours,” ask yourself three things:
A time-cost calculator can't measure joy, convenience, safety or a meaningful memory. That's a feature of being human, not a flaw in the maths.
One important catch: 48 hours of work isn't 48 hours until you can afford it
This is an earnings equivalent, not a savings countdown. If you earn $25 an hour after tax, 48 hours brings in $1,200—but some of that income may already be needed for housing, food, bills or other commitments. Saving $1,200 could take much longer.
The life-cost calculator also uses a five-day workweek and a 48-week working year when translating hours into working days, months and years. It doesn't add commuting time or work-related expenses, and the five-day assumption may not reflect your actual schedule. Those details can change how a result feels.
The hours figure is still useful. Just don't confuse it with a literal reduction in your lifespan, or a promise that you can afford the purchase after working that many hours.
Try this before your next checkout
Think of something currently sitting in your shopping cart. Maybe it's $40. Maybe it's $4,000.
Now turn that number into working hours. Picture the shifts, the early alarms, the busy afternoons. Then picture what the purchase brings to your life once it's yours.
Would you happily make that trade?
If the answer is yes, enjoy it. If you're unsure, maybe give it a day. Either way, you've made the decision with a clearer picture of what you're exchanging.
Quick questions about the time cost of a purchase
How do I calculate how many hours I need to work to buy something?
Divide the price by your hourly take-home pay. For example, $500 ÷ $25 per hour = 20 hours of work. That measures earnings, not how quickly you can save after expenses.
What if I'm paid a salary rather than an hourly wage?
Divide your take-home pay for a typical week by the hours you actually work in that week. If your weekly take-home pay is $1,000 and you work 40 hours, your after-tax hourly rate is $25.
Should I include the time spent commuting?
The CozyCalcs calculator doesn't include it. If you want a more complete personal estimate, you can separately think about unpaid commuting time and costs you incur because of work. Avoid treating the simple calculator result as a precise measure of every hour your job uses.
Does this mean spending money is a waste of my life?
No. You're buying things to live, not trying to win a competition to spend the least. The point is to ask whether a purchase feels worth the time it takes to earn its price—and to leave room for the answer to be yes.
