Standard vs Actual Expenses Calculator

Run both methods side by side. For most self-employed drivers, the standard mileage rate saves more money with less work. But not always. Enter your real numbers and see the difference for your specific situation.

Federal estimate only. The first-year election locks in your method for that vehicle. If you choose actual expenses in year one, you generally cannot switch to the standard rate later. If unsure, start with the standard rate to preserve the option to switch.

How the standard mileage rate works

Multiply your business miles by the IRS rate. For 2026, that rate is 72.5 cents per mile.

You do not track gas, insurance, repairs, or depreciation. The IRS rate is meant to cover all of those costs in a single number. You still need a mileage log with the date, destination, purpose, and miles for each trip. And you can still deduct business-related parking and tolls on top of the mileage rate.

How the actual expenses method works

Track every cost of owning and operating your vehicle for the year. Then multiply the total by your business-use percentage.

Costs you include: gas and oil, insurance premiums, repairs and maintenance, tires, registration and license fees, depreciation (or lease payments if leasing), loan interest (the business-use portion), and car washes.

Your business-use percentage is simple: business miles divided by total miles. If you drove 20,000 total miles and 14,000 were for business, your business-use percentage is 70%.

When the standard mileage rate wins

Newer vehicles where depreciation is high but already factored into the 72.5-cent rate. The IRS rate assumes average depreciation, insurance, and fuel costs.

High-mileage drivers. The more business miles you drive, the larger the gap between the standard deduction and your fixed costs spread across those miles.

Fuel-efficient or electric vehicles. If your car costs 8 to 10 cents per mile in fuel instead of 15 to 18 cents, the 72.5-cent rate is particularly generous. EV owners benefit the most here.

When actual expenses win

Older, paid-off vehicleswith minimal depreciation remaining. The standard rate includes a depreciation component. If your car is fully depreciated, you are "wasting" that portion of the rate.

Expensive vehicles with high insurance, repair, and operating costs.

Low total mileage with high costs. If you only drive 8,000 miles total but spend $12,000/year on vehicle expenses, your actual per-mile cost is more than double the standard rate.

The first-year rule

This is the most important restriction. If you want the option to use the standard mileage rate for a vehicle, you must choose it in the first year that vehicle is used for business.

Start with the standard rate in year one, and you can switch to actual expenses in any future year. Start with actual expenses in year one, and you are generally locked into that method for the life of that vehicle. If you are unsure which method is better, start with the standard rate. You preserve the option to switch.

FAQ

Can I switch between methods every year?

Only if you started with the standard mileage rate in year one. In that case, you can switch to actual expenses in a later year (using straight-line depreciation). You cannot switch back to standard after using actual expenses.

Do I have to use the same method for all my vehicles?

No. Each vehicle is independent. You can use the standard rate for one and actual expenses for another. The exception is fleets of five or more simultaneous vehicles, which must all use actual expenses.

Can I deduct gas on top of the standard mileage rate?

No. The 72.5-cent rate already includes gas, oil, insurance, depreciation, and maintenance. You can only add parking fees and tolls. To deduct gas separately, use the actual expenses method.

What about lease payments?

If you lease a vehicle, you can use either method. But if you choose the standard mileage rate, you must use it for the entire lease period, including renewals. Under actual expenses, you deduct the business-use portion of your lease payments instead of depreciation.

Which method do most people use?

The standard mileage rate. It is simpler, requires less recordkeeping, and produces a larger deduction for the majority of drivers with newer vehicles and moderate-to-high business mileage.
