TimeWasted is a personal finance app that converts every expense into the work hours it cost you to earn. You enter your salary or hourly rate, log any purchase, and instantly see how many hours of your working life that item represents — not just its price in currency.

How does TimeWasted calculate work hours per purchase?

TimeWasted divides the price of a purchase by your net hourly rate (your salary divided by your working hours). For example, if you earn €15/hour after tax and buy a €90 item, TimeWasted shows it cost you 6 hours of work. This makes the true cost of spending immediately visible.

Is there an app that shows how many hours of work a purchase costs?

Yes — TimeWasted (timewasted.app) does exactly this. You enter your hourly rate or monthly salary, then log any expense. The app instantly converts the purchase price into the number of work hours required to earn it. It's free to use and works on web, iOS, and Android.

How can I see how many work hours a purchase costs?

Use TimeWasted: sign up at timewasted.app, enter your salary or hourly rate, and start logging purchases. The app automatically converts every expense into work hours based on your rate. A €50 expense for someone earning €10/hour costs 5 hours of work.

Yes, TimeWasted has a free plan with no credit card required. You can sign up at timewasted.app and start converting expenses to work hours immediately.

What is the "time cost of money" concept?

The time cost of money (also called "life energy" in personal finance) is the idea that every purchase costs not just currency, but hours of your life. If you earn €20/hour, a €200 item costs 10 hours of your life. TimeWasted is built around this concept, helping users see the real cost of every spending decision.

How is TimeWasted different from other expense trackers?

Most expense trackers show spending in money. TimeWasted shows spending in time — specifically, the hours of work required to earn what you spent. This reframing makes the true cost of purchases tangible and helps users make more intentional spending decisions.

Impulse Buying Is Stealing Your Time — Here's the Proof

Impulse buying is not a character flaw. It is the result of systems built by some of the world's best engineers and psychologists — from e-commerce algorithms to store layouts to "limited time offer" countdown timers. You are not weak. You are the intended target.

But understanding that does not protect your money — or your time. And once you start measuring impulse purchases in work hours, the picture becomes very clear very quickly.

How Much Impulse Buying Actually Costs

Research consistently shows that 40–80% of all purchases are unplanned to some degree. A 2023 study found that the average European spends €189/month on impulse purchases. At a net hourly rate of €12, that is 15.75 hours of work per month — almost two full working days — spent on things you did not plan to buy.

Over a year, €189/month in impulse spending at €12/hour = 189 hours of work = nearly 5 full work weeks spent funding unplanned purchases.

Why Impulse Buying Feels Free

Paying with a card or phone removes the physical sensation of spending. You do not feel money leaving — you just tap. Online shopping is even more disconnected: future-you pays for present-you's click. These payment mechanisms are specifically designed to reduce the psychological "pain of paying."

Seeing the purchase converted to work hours reintroduces that pain in a meaningful way. A €35 item is abstract. The 2 hours and 55 minutes you worked on Tuesday morning to cover it is not.

The Work-Hours Pause

Before any unplanned purchase, try one thing: calculate how many hours it costs you. You do not need TimeWasted for this — just divide the price by your hourly rate.

Example

You earn €14/hour. You are about to buy a €45 item on impulse. That is 3.2 hours of work. Ask yourself: would I work an extra 3 hours and 12 minutes specifically to buy this right now? If the answer is no, do not buy it.

The 24-Hour Rule in Work Hours

A useful technique: for any unplanned purchase over 2 hours of your work time, wait 24 hours before buying. Most impulse purchases lose their appeal completely within a day. The item will almost certainly still be available tomorrow.

Tracking Impulse Spending in TimeWasted

TimeWasted lets you categorize expenses. Over time, you can see what percentage of your spending was unplanned versus intentional. Most users are surprised to discover that impulse and semi-impulse purchases account for 20–35% of their monthly total — nearly all in small amounts that felt harmless individually.

Visibility is the cure. Once you can see the pattern, you can break it.
