Cost Per Active Minute Calculator
Cost of a gadget or tool divided by the minutes you've actually used it.
Calculate cost per minute of active use for a gadget, tool, or subscription. Normalises cost against actual utilisation.
What this tool does
A 500 gadget used 30 minutes a week for two years has a very different cost-per-minute than the same gadget used daily. Enter purchase price, minutes of active use per week, and ownership period. The tool returns cost per minute and per hour of actual use.

A 500 juicer used 10 minutes twice a week over 2 years adds up to 2,080 minutes of use — 24p per minute or 14.42 per hour. Makes more sense than the juicer you use once after purchase and once a year after that, which costs 3-6 per minute. Cost-per-minute makes purchase decisions brutally honest.
What the result means
Primary is cost per minute. Secondary shows cost per hour, total use time, and total purchases that would break-even at 1/minute. A high cost-per-minute flags underused gear.
What this doesn't capture
Enjoyment value. A 500 bike used 100 minutes a week over 10 years is 9p/minute — tiny. But the point isn't to minimise cost-per-minute; it's to make cost visible when utilisation is low. Use this before buying, not just after.
Quick example
With purchase price of 500 and minutes of use per week of 20 (plus years owned of 2 years), the result is 0.24. Change any figure and watch the output shift — it's often more useful to see the pattern than to memorise the formula.
Which inputs matter most
You enter Purchase Price, Minutes of Use Per Week, and Years Owned. Frequency and unit price pull the total in different directions. The biggest surprise for most people is how small recurring amounts compound into large annual figures — that's where this calculation earns its keep.
What's happening under the hood
Cost per minute equals price divided by total minutes used over ownership. Total minutes is minutes-per-week × 52 × years. Excludes running costs and depreciation — gross purchase-price analysis only. The formula is listed in full below. If the number looks off, you can retrace the calculation by hand — that's the point of showing the working.
Using this without guilt
The figure here isn't a verdict on whether the spending is "worth it". That judgment is yours to make. What the number does is shift the question from "can I afford this?" to "is this what I want my money doing over a decade?". Both questions matter.
Your cost per minute of active use is shown above.
