Enter a week, a day or a whole year. This subtracts what your vehicle really costs per mile from what the apps paid you, and prices your business miles at both of 2026's IRS standard mileage rates separately.

Your vehicle cost and your mileage deduction are not the same number and they do not belong in the same subtraction. The vehicle cost is money that actually left your pocket or came off your car's value. The deduction is a figure that reduces taxable income on a return. Subtracting the deduction from your gross as if it were an expense, which several free calculators do, double-counts the car and makes the week look worse than it was.
This page shows them apart on purpose. The headline figure is cash reality: gross minus what the miles cost you. The deduction table underneath is the tax figure, priced at the rate in force on the day each mile was driven.
2026 is a split year. The IRS set the business standard mileage rate at 72.5 cents a mile for January 1 through June 30, then raised it to 76 cents for July 1 through December 31. A mile is worth 3.5 cents more in August than it was in May.
That means one rate for the whole year is wrong in both directions: it understates the second half and overstates the first. Any log that covers both halves needs the miles split at June 30 and each half priced on its own. That is what the second table does, and it is why this calculator asks for two mileage figures rather than one.

The starting numbers for each vehicle class are the five-year averages published in AAA's annual Your Driving Costs study, 2025 edition, at its 15,000 miles a year baseline. Depreciation is then rescaled to the annual mileage you enter, because per-mile depreciation falls as you drive more: the same dollar loss spreads over more miles. Fuel is recomputed from the price and MPG you give rather than AAA's national average.
Two components are off by default and most gig drivers should leave them off. License, registration and taxes are owed whether or not you drive for an app, and finance charges only apply if the car is financed. Turn them on if you want the full cost of ownership rather than the cost of driving.

Insurance is a national average and will be the component furthest from your own number, so override it with the vehicle class closest to your real premium if it matters.
No. It is arithmetic on the numbers you type in. It does not tell you what you may deduct, whether the standard mileage method is the right one for your situation, or what you owe. Nothing here is reviewed by a tax professional and no outcome is guaranteed. Talk to someone qualified before you file.
No. The whole calculation is JavaScript running on your device. There is no request, no logging, no cookie and no storage. You can turn off your connection and it still works.
Each mile takes the rate in force on the day it was driven, so a week running from June 28 to July 4 has miles in both periods. Split the odometer at the end of June 30 and enter each half in its own box.
Because the platforms quote gross and count only the time they consider you engaged. This counts every hour you enter and takes the vehicle out first. The gap between those two numbers is the entire point of the exercise.
Self-employment tax is 15.3 percent, made up of 12.4 percent for Social Security and 2.9 percent for Medicare, and it generally applies to 92.35 percent of net earnings from self-employment. The optional line applies those two figures to your net so you can see roughly what not to spend. It is an estimate of one tax only, it ignores income tax, deductions, credits, the Social Security wage cap and anything else on your return, and it is not advice.
Yes. Add the gross from every platform together and enter total miles. Per-platform numbers are a different question, and the useful version of it needs a log rather than a calculator.
These figures are the same arithmetic MileTruth runs, ported to run in a browser. The app's job is the part a calculator cannot do: keeping the log. It records each trip with its own date, classifies business against personal, and prices every mile at the rate in force that day, so the June 30 split happens by itself instead of being something you have to remember at tax time.
MileTruth is not released yet. There is no App Store or Play listing to send you to yet, and nothing to buy: no price has been set and nothing is charged. The calculators on this site are free and will stay free whether or not the app ever ships.
