Standard Mileage Rate vs Actual Expenses: Which Saves You More?

For most self-employed drivers, the standard mileage rate saves more money with less work. But not always. If you drive an older, paid-off vehicle, the actual expenses method can produce a larger deduction. The right choice depends on your car, your costs, and your willingness to keep receipts.

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.

Example: You drove 14,000 business miles in 2026. Deduction: 14,000 × $0.725 = $10,150. Add $420 in tolls and $210 in client parking. Total: $10,780.

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)
• 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%.

Example: Same 14,000 business miles out of 20,000 total (70% business use). Your total vehicle costs: $3,800 gas, $1,500 insurance, $1,100 repairs, $850 registration and fees, $2,400 depreciation = $9,650. Deduction: $9,650 × 70% = $6,755. Add $420 tolls and $210 parking. Total: $7,385.

In this case, the standard method wins by $3,395.

Side-by-Side Comparison

When the Standard Mileage Rate Wins

The standard rate works in your favor when the IRS rate exceeds your actual per-mile costs. That happens most often with:

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. If your car is financed and you are paying both a car payment and fuel, the standard rate often exceeds what you would calculate under actual expenses.

High-mileage drivers. The more business miles you drive, the larger the gap between the standard deduction and your fixed costs (insurance, registration) spread across those miles. A driver doing 20,000 business miles gets a $14,500 standard deduction. Their actual costs would need to be extraordinarily high to beat that.

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

When Actual Expenses Win

Older, paid-off vehicles with minimal depreciation remaining. The standard rate includes a depreciation component. If your car is fully depreciated or nearly so, you are "wasting" that portion of the rate. Meanwhile, you may still have meaningful repair and insurance costs that push your actual per-mile expenses higher than 72.5 cents.

Expensive vehicles with high insurance, repair, and operating costs. A $60,000 truck with $2,500/year insurance, $2,000 in repairs, and $5,000 in fuel might produce a higher actual-expense deduction than the standard rate, especially if total miles are relatively low.

Low total mileage with high costs. If you only drive 8,000 miles total (6,000 business) but spend $12,000/year on vehicle expenses, your actual per-mile cost is $1.50. That 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.

The reason: the actual expenses method involves claiming depreciation on the vehicle. Once you have taken MACRS depreciation, Section 179, or bonus depreciation on a car, the IRS does not let you go back to the standard rate (which includes its own depreciation component). You would effectively be double-counting.

If you are unsure which method is better, start with the standard rate. You preserve the option to switch. There is no equivalent safety net in the other direction.

Switching Methods in Later Years

If you chose the standard rate in year one, you can switch to actual expenses in year two or any later year. However, when you switch, you must use straight-line depreciation for the remaining useful life of the vehicle. You cannot use MACRS or accelerated depreciation after having used the standard rate.

If you chose actual expenses in year one, you generally must continue using actual expenses for that vehicle. The exceptions are narrow and rarely apply.

You can use different methods for different vehicles. If you have two cars, one can be on the standard rate and the other on actual expenses. Each vehicle's election is independent.

Five or More Vehicles

If you use five or more vehicles for business simultaneously (a fleet), you cannot use the standard mileage rate for any of them. You must use the actual expenses method. This applies to businesses like delivery services, landscaping companies, and car dealerships with multiple vehicles in active use.

How to Decide

Run the numbers for both methods using your actual figures from last year. The mileage deduction calculator handles the standard method. For actual expenses, add up your total vehicle costs and multiply by your business-use percentage.

If the standard rate produces a larger deduction, use it. If actual expenses produce a larger deduction and this is not the first year of business use, use actual. If this is the first year: use the standard rate unless actual expenses are clearly and significantly better, because 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. If you want to deduct gas separately, you must 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. You cannot switch mid-lease. 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.
