How many hours of your life does a purchase cost?
The time vs money calculator converts any purchase into the hours of your life it costs you to earn — after tax. A $1,200 phone for someone netting $30/hour after tax isn't '$1,200' — it's 40 hours, a full work-week. This reframing is one of the oldest and most powerful tools in personal finance (popularized by 'Your Money or Your Life'), and it changes purchase decisions in a way that pure dollar amounts rarely do.
