Hobby Cost Per Mile Calculator
Work out the true cost per mile of a distance hobby like cycling, running or road-tripping, gear and upkeep included.
How it works
Cost per mile = (gear + yearly cost × years) ÷ (miles per year × years)
Distance hobbies feel free once the gear is bought, but the up-front kit is a real cost that should be spread across every mile it enables. Amortizing the equipment over its useful life and adding running costs gives a per-mile figure you can compare against the enjoyment — or against cheaper alternatives. The more miles you log, the faster the fixed gear cost dilutes away.
Worked example
A $2,000 bike with $400 a year of upkeep, ridden 2,500 miles a year for 4 years, covers 10,000 miles at a total cost of $2,000 + $1,600 = $3,600. That is $0.36 per mile, or an effective $900 a year.
Frequently asked questions
Why include the gear cost if I already bought it?
Because the equipment is what makes the miles possible, and it wears out. Spreading its price over the miles it enables shows the real cost of the hobby; ignoring it makes any activity look artificially free.
How does mileage change the number?
Fixed costs like gear are divided by total miles, so doubling your mileage roughly halves the gear share of cost per mile. High-volume hobbyists get far more value from the same equipment than occasional users.
