Every purchase has two prices: the number on the tag, and the number of hours of your life you traded to afford it. The second one is usually more useful for deciding whether something is really worth it.
Divide the price of an item by your net hourly pay (take-home pay after tax and National Insurance, divided by hours worked) to see how many hours of work it really costs. A £1,200 laptop at a net hourly rate of £15 costs 80 hours of work — two full weeks — which reads very differently from just '£1,200'.
Use the Work Hours Calculator on this site to convert any price into hours of your own work automatically.
Thinking in hours worked makes trade-offs concrete: it's easier to skip a purchase when you can picture the actual hours of work behind it, rather than an abstract number. It also highlights that raising your net hourly pay — through a rise, a side income, or reducing your tax bill via pension contributions or ISA use — makes every future purchase cost fewer hours of your life.
