"Time is money" gets used so often it's easy to stop hearing it. But taken literally, it's a genuinely useful way to evaluate spending: every dollar you spend represents some amount of time you traded to earn it, whether that's an hour of an hourly wage or a proportional slice of a salary.

Converting price into hours

If you earn roughly $25 an hour after taxes, a $75 purchase is three hours of work, not just seventy-five dollars. That reframing doesn't make the purchase wrong — plenty of three-hour purchases are worth it — but it changes the question from "can I afford this" to "is this worth three hours of my time," which tends to be a more honest question for a lot of discretionary spending.

Where this is most useful

The hourly lens is most revealing on recurring costs, because it compounds. A $50/month subscription isn't just $50 — over a year, at $25/hour, it's roughly 24 hours, a full workday, just to cover something you might not even use every week. Seen that way, a lot of "small" recurring charges look different than they do as an isolated monthly line item.

This isn't a call to convert every purchase into a time calculation — that's its own kind of exhausting. It's a lens worth applying occasionally, especially to recurring costs, as a gut check on whether something's actually earning the time it costs.
