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.

I Tracked Every Purchase in Work Hours for 30 Days — Here's What Happened

I am a primary school teacher earning €1,680/month take-home. My hourly rate works out to about €10.50/hour after everything. I thought I was reasonably careful with money. I was wrong.

For 30 days I logged every single purchase — down to the €1.20 coffee from the vending machine — in TimeWasted, and watched it convert to minutes and hours of work. Here is what that month taught me.

Week 1: The Shock

The first week was uncomfortable. Not because I was spending extravagantly, but because I could see — in real time — the work hours draining away. A Tuesday evening takeaway: €22. Two hours and six minutes of work. A jacket I saw on sale and "needed": €65. Six hours and twelve minutes of work.

I did not stop spending in week one, but I started hesitating. Every time I was about to tap my card, there was a new question forming in my mind: "How many hours is this?"

Week 2: The Patterns Emerge

By week two, I could see clear patterns in my TimeWasted dashboard. Eating out was my biggest non-fixed cost category: €87 in the first two weeks, which was 8.3 hours of my working life. Most of it happened on evenings when I was too tired to cook.

I realized I was not paying for food when I ordered takeaway. I was paying to avoid cooking when I was exhausted — and the price was hours of work I had already spent.

The Full Month Breakdown

Rent: €550 → 52.4 hours
Groceries: €180 → 17.1 hours
Eating out / takeaway: €156 → 14.9 hours
Transport: €80 → 7.6 hours
Subscriptions: €43 → 4.1 hours
Shopping / clothes / misc: €112 → 10.7 hours
Coffee out: €38 → 3.6 hours
Total tracked: €1,159 → 110.4 hours

That is 110 hours of work to cover one month of my life. I work 160 hours a month. The remaining 50 hours went to savings and a small buffer.

What Changed in Month 2

I did not set strict budgets. I just kept tracking. But seeing the numbers in hours made several changes feel obvious and easy:

Cancelled two streaming services I barely used: saved 2.1 hours/month
Started batch cooking on Sundays: reduced takeaway to €60/month, saving 9.1 hours
Stopped buying coffee out on weekdays: saved 2.8 hours/month

Total monthly savings: around €119 per month, or 11.3 hours of work reclaimed — every single month, going forward.

The Conclusion

I am not a minimalist. I did not stop enjoying life. But I stopped spending money unconsciously — and that is the only change TimeWasted made. It forced every purchase into the open. Once I could see the hours, decisions made themselves.
