Gas is the cost every driver tracks, because it's the one you pay for weekly, at the pump, in a way you can't ignore. Tires, maintenance, insurance, and depreciation are just as real, but they show up as occasional large bills or as a lower resale number down the line — easy to underweight because they don't hit your wallet every week the way gas does.
Why cost-per-mile is the number that actually matters
A single number — true cost per mile — folds every one of those expenses into something you can compare directly against a trip offer. Our cost-per-mile calculator adds up a full year of fuel, maintenance, tires, insurance, registration, and depreciation, then divides by your annual miles to get that one number.
Depreciation: the cost drivers most consistently underestimate
Depreciation rarely gets factored into daily decisions because no one writes a check for it — but a car driven 30,000+ rideshare miles a year loses value meaningfully faster than one driven a typical 12,000. The calculator handles this by asking for your car's value now and its estimated value a year from now at that higher mileage, which captures the real number rather than a generic industry average.
Comparing your cost per mile to the IRS rate
This comparison decides which tax deduction method makes more sense for you — see our taxes guide for the full mechanics. If your calculated true cost per mile comes in under the current IRS standard mileage rate, the standard deduction usually beats tracking and deducting actual expenses. If it's higher — common for larger vehicles or ones already showing heavy wear — actual expenses may save more, provided you keep receipts.
Using it to set your own minimum acceptable fare
Once you know your true cost per mile, a reasonable floor for accepting a trip is roughly double that number — enough to cover the paid miles plus the unpaid ones you'll drive getting to the next pickup. The calculator surfaces this as a direct "minimum per-mile offer" figure, useful as a fast gut-check when a low-paying ping comes in.
FAQ
- Is depreciation really worth factoring into daily decisions?
- Yes, even though it's invisible week to week — it's frequently the single largest cost category rideshare drivers underweight, since it never appears as a bill, only as a lower resale or trade-in value later.
- How is this different from the profit calculator?
- The profit calculator focuses on a single week's earnings and expenses to show your net hourly pay. This tool zooms out to a full year of vehicle costs to answer a narrower, more precise question: what does each mile actually cost you, independent of any specific week's earnings?
- Should I use this before buying a car for rideshare driving?
- Absolutely — running the numbers on a car you're considering, using its expected depreciation and fuel efficiency, is one of the most useful pre-purchase checks a prospective driver can do.
