Mileage Reimbursement Calculator: How Much Should You Get Paid for Business Miles?
If you use your personal car for work—delivering goods, visiting clients, or driving to off-site meetings—you’re entitled to reimbursement for those business miles. But how much should you receive? The IRS sets a standard mileage rate, but many employers offer their own custom rates. Our Mileage Reimbursement Calculator helps you calculate exactly what you should be paid, and even compares it with your actual driving costs (fuel, depreciation, and maintenance). This free tool is essential for freelancers, employees, and small business owners.
Mileage Reimbursement Calculator
Why You Need This Calculator
The IRS standard mileage rate for 2026 is $0.67 per mile. This rate is designed to cover the average cost of operating a vehicle, including fuel, maintenance, insurance, and depreciation. However, if you drive a fuel-efficient car or a gas guzzler, your actual costs may be higher or lower. Our calculator lets you compare your reimbursement against your real expenses, so you can see whether you’re being fairly compensated or losing money on business trips.
How the Calculator Works
You input:
- Business Miles Driven – the number of miles you traveled for work.
- Rate Type – choose the IRS standard rate (1) or enter a custom rate (2).
- Custom Rate – if you chose custom, enter your employer’s rate per mile.
- Optional Actual Costs – enter your vehicle’s fuel economy, fuel price, annual depreciation, and total annual miles to estimate real expenses.
The calculator then calculates:
- Reimbursement Amount – business miles × rate.
- Rate Used – the per-mile rate applied.
- Estimated Fuel Cost – (business miles / fuel economy) × fuel price.
- Depreciation/Maintenance Share – (business miles / total annual miles) × annual depreciation.
- Total Actual Cost – sum of fuel and depreciation.
- Net Gain or Loss – reimbursement minus actual cost.
- Actual Cost per Mile – your real cost for each business mile.
- Reimbursement Coverage – percentage of your actual costs covered by the reimbursement.
Example: Sarah’s Deliveries
Sarah is a freelance photographer who drives 2,000 business miles a month. Her employer reimburses at the IRS rate. She drives a 2019 Honda Civic (35 MPG), pays $3.50/gallon for gas, and estimates her annual depreciation at $2,500. She drives 15,000 miles per year.
- Reimbursement: 2,000 × $0.67 = $1,340
- Fuel cost: (2,000 / 35) × 3.50 = 57.14 × 3.50 = $200
- Depreciation share: (2,000 / 15,000) × $2,500 = $333.33
- Total actual cost: $533.33
- Net gain: $1,340 – $533.33 = $806.67
- Actual cost per mile: $533.33 / 2,000 = $0.2667 (26.7 cents)
- Coverage: $1,340 / $533.33 × 100 = 251%
Sarah is thrilled to see she’s actually making a profit on her business miles—$806.67 per month! This is because the IRS rate is higher than her actual cost. However, if she drove a gas-guzzling SUV, the result might be different. The calculator gives her clarity.
Real-World Case Study: Mike’s Delivery Job
Mike drives for a delivery company. He uses his own car (a 2016 Ford Focus, 28 MPG), drives 3,000 business miles a month, and receives a custom rate of $0.55 per mile. His fuel costs $3.60/gallon, and annual depreciation is $3,000 over 12,000 miles.
- Reimbursement: 3,000 × $0.55 = $1,650
- Fuel cost: (3,000 / 28) × 3.60 = 107.14 × 3.60 = $385.71
- Depreciation share: (3,000 / 12,000) × $3,000 = $750
- Total actual cost: $1,135.71
- Net gain: $1,650 – $1,135.71 = $514.29
- Coverage: $1,650 / $1,135.71 × 100 = 145%
Mike is still making money, but not as much as Sarah. If his employer paid only $0.40 per mile, he’d actually lose money. The calculator helps him negotiate a fair rate.
The Impact of Fuel Economy
Your car’s fuel efficiency is the biggest factor in determining your actual cost per mile. A car getting 20 MPG costs more per mile than one getting 40 MPG. Our calculator uses your fuel economy and fuel price to estimate the fuel portion of your costs, so you can see how your specific vehicle affects the math.
