The context behind the number
Read on 25 evenings a month for seven years, a Kindle costs roughly 7 cents per reading session — cheaper than a library late fee.
How we calculate the time-cost
- 1We start with your net take-home income — what actually lands in your bank account after taxes, social contributions, and mandatory deductions.
- 2We divide that by your real working hours per week, including overtime, commuting, and any unpaid work preparation, to arrive at your true hourly wage.
- 3We then divide the item price by your true hourly wage to get the raw number of work-hours the purchase costs.
- 4Finally, we convert those hours into a human-readable breakdown of years, months, days, and hours so you can immediately feel the weight of the number.
This approach follows the methodology described in "Your Money or Your Life" by Vicki Robin — one of the foundational texts of the financial independence movement.
