Mileage Reimbursement Calculator

Drove 500 miles for work in 2025? At the IRS business standard mileage rate of 70 cents per mile, that is $350 in reimbursement — no receipts for gas or repairs required. This mileage reimbursement calculator takes the miles you drove and the purpose of the trip and instantly applies the correct 2025 IRS rate, then shows what the same drive would be worth for business, medical, and charitable use side by side.

How mileage reimbursement is calculated

The math is deliberately simple. You multiply the miles you drove by the per-mile rate for that purpose:

So 1,200 business miles at the 2025 rate is 1,200 × $0.70 = $840. The standard mileage rate is designed to bundle every cost of running your car — fuel, oil, maintenance, tires, insurance, registration and depreciation — into one number, which is why you do not submit individual receipts when you use it.

The 2025 IRS standard mileage rates

The IRS publishes the standard mileage rates each year (usually in December for the year ahead). For 2025 they are:

• Business: 70¢ per mile — driving for work, up 3 cents from 67¢ in 2024.
• Medical & moving: 21¢ per mile — travel for medical care, and moving for active-duty members of the armed forces.
• Charitable: 14¢ per mile — driving in service of a qualified charity. This rate is fixed by statute.

Because the charitable rate is set by law rather than recalculated from driving costs, it has stayed at 14 cents for years while the business rate has climbed with fuel and vehicle prices.

How to use this calculator

You only need two numbers to get an answer. Work through the fields in order:

1. Miles driven: enter the total qualifying miles from your log. Use the quick buttons (100, 500, 1,000, 5,000) for a fast estimate.
2. Purpose: choose business, medical/moving, or charitable — the calculator selects the matching 2025 IRS rate automatically.
3. Custom rate (optional): tick the box if your employer reimburses at a rate other than the IRS standard, then enter the cents-per-mile figure. The result shows how it compares to the IRS amount and flags any taxable excess.

The large dollar figure at the top is your total reimbursement. Below it, a comparison table shows what the same miles are worth at all three IRS rates.

Who this calculator is for

• Employees submitting a mileage expense report and checking the amount before they file it.
• Employers and bookkeepers reimbursing staff at the IRS rate and needing a quick, defensible number.
• Self-employed and gig workers (rideshare, delivery, contractors) estimating their Schedule C mileage deduction.
• Volunteers tracking charitable driving for an itemized deduction.
• Anyone deciding between the standard rate and the actual-expense method.

Worked example: a sales rep's month

Suppose a sales rep logs 1,450 business miles in a month visiting clients (commuting from home to the office does not count). At 70¢/mile that is 1,450 × $0.70 = $1,015 in reimbursement. If the same person also drove 120 miles for medical appointments that month, those are valued separately at 21¢/mile = $25.20. The two purposes never mix rates: each block of miles is multiplied by its own rate.

Scenario: custom employer rate above the IRS rate

Say your company reimburses 75¢ per mile for business driving and you logged 1,000 miles. Your check is 1,000 × $0.75 = $750. The IRS standard amount would be 1,000 × $0.70 = $700, so $50 of your reimbursement is paid above the IRS rate. Under IRS rules, that $50 excess is generally treated as taxable wages unless you substantiate higher actual costs. This calculator flags that excess automatically when you enter a custom rate.

Scenario: choosing the standard rate vs. actual expenses

A contractor drives 10,000 business miles a year. At the standard rate that is 10,000 × $0.70 = $7,000. If her real costs (gas, insurance, repairs, depreciation) for the business share of the car come to $6,000, the standard rate wins. If she drives an expensive truck with heavy repair bills totaling $9,000 of business-use costs, the actual-expense method wins. The standard rate is simpler and usually better for fuel-efficient, lower-cost vehicles.

Key mileage terms explained

• Standard mileage rate: the per-mile figure the IRS sets that bundles all vehicle operating costs into one number.
• Accountable plan: an employer reimbursement arrangement where you substantiate the miles; payments under it at or below the IRS rate are not taxable.
• Commuting miles: home-to-work driving, which is personal and never reimbursable at the business rate.
• Actual-expense method: deducting the business share of real vehicle costs instead of using the standard rate.
• Contemporaneous log: a mileage record kept at or near the time of each trip, showing date, destination, purpose and miles.

What changes the result the most

• Miles driven: the direct multiplier — every extra qualifying mile adds the per-mile rate.
• Purpose: business (70¢) pays five times the charitable rate (14¢) for the same distance.
• Tax year: the rate changes annually; use the right year's rate for the miles you drove.
• Custom employer rate: reimbursing above the IRS rate can create taxable wages.

Tips to maximize a defensible reimbursement

• Log every trip as it happens — date, start and end points, purpose and miles. Reconstructed logs fare poorly under audit.
• Separate parking and tolls — these are reimbursable on top of the mileage rate, so list them separately.
• Exclude your commute — only count miles beyond regular home-to-work travel.
• Pick a method early — if you want the standard rate for business, you generally must choose it the first year the car is in service.

How the IRS business mileage rate has changed by year

The business standard mileage rate moves with the cost of owning and operating a vehicle, so it is worth checking the rate that matched the year you actually drove. If you are amending a prior-year expense report or filing back taxes, do not apply the 2025 figure to 2023 miles. Recent business rates have been:

• 2025: 70¢ per mile — the current rate, up 3 cents.
• 2024: 67¢ per mile — up 1.5 cents from the prior year.
• 2023: 65.5¢ per mile — a full-year rate after a mid-2022 increase.
• 2022: 58.5¢ (Jan–Jun) then 62.5¢ (Jul–Dec) — the IRS raised the rate mid-year because of a fuel-price spike, which is rare.

The 14¢ charitable rate stayed flat across every one of those years because Congress, not the IRS, sets it. The medical and moving rate, by contrast, tracks variable operating costs and has bounced between roughly 16¢ and 22¢. When you submit a reimbursement that spans a rate change, split the miles by the date driven and apply each period's rate to the matching block of miles.

Self-employed and gig drivers: turning miles into a deduction

For a sole proprietor, rideshare driver, or delivery contractor, business mileage is not "reimbursed" — it is deducted on Schedule C, which lowers both your income tax and your self-employment tax. The mechanics still start with this calculator: total your qualifying business miles, multiply by 70¢, and that dollar figure is the deduction. A driver who logs 18,000 business miles in 2025 deducts 18,000 × $0.70 = $12,600 against gross earnings before tax is figured.

Because gig platforms only report your gross fares, the mileage deduction is often the single largest write-off a driver has, and the one most commonly under-claimed. Track every leg you can legitimately count: miles driving to your first pickup, between trips while logged in and available, and from your last drop-off back toward home up to the point your shift ends. Once you know your net Schedule C profit, run it through the Self-Employment Tax Calculator to see the 15.3% Social Security and Medicare bite, and the Income Tax Calculator for the federal layer. One caveat: if you ever used the actual-expense method and claimed depreciation on a vehicle, you generally cannot switch back to the standard rate for that car.

Federal rate vs. state and company rules

The IRS rate is a federal tax figure — it sets the ceiling for what an employer can reimburse you tax-free, and the rate the self-employed deduct. It does not, by itself, require any employer to pay it. Most private employers in most states are free to set their own cents-per-mile figure, pay a flat car allowance instead, or reimburse nothing at all for a salaried role. A handful of states (notably California, Illinois, and Massachusetts) do legally require employers to reimburse necessary business driving expenses, and many of those employers simply adopt the IRS rate because it is the cleanest defensible number.

This is why the custom-rate field matters. If your company pays a flat $0.60 while the IRS rate is $0.70, you are absorbing 10¢ of real cost per mile that you generally cannot recover as a W-2 employee, since the Tax Cuts and Jobs Act suspended the unreimbursed-employee-expense deduction through 2025. Enter both figures here to quantify that gap before you negotiate. If instead you receive a fixed monthly car allowance rather than per-mile pay, that allowance is usually taxable wages in full unless it is paid under an accountable plan tied to documented miles — a key distinction many employees miss.

Limitations and assumptions

• It applies the 2025 IRS rates only; earlier or later years use different rates.
• It does not add parking, tolls, or ferry fees, which are claimed separately from the mileage rate.
• It does not model the actual-expense method or vehicle depreciation schedules.
• It does not determine whether a trip qualifies — you must apply the IRS rules on business, medical and charitable use.
• State reimbursement rules and your specific tax situation may differ; confirm with the IRS or a tax professional.
