How to Use This Cost Per Mile Calculator

Enter your fuel price per gallon and your vehicle fuel economy in MPG. Add your monthly miles driven. Then fill in your monthly costs across fixed and variable categories. The calculator returns your cost per mile, fuel cost per mile, monthly total, annual total, and a full percentage breakdown by cost category.You do not need to fill every field. Enter only the costs you want to include.The calculator works with fuel only, or with all costs together.

Enter Your Fuel Costs

Enter your current fuel price per gallon and your vehicle MPG. Your fuel cost per mile is simply price divided by MPG. At $3.80 per gallon and 25 MPG, your fuel cost is $0.152 per mile. Use our MPG calculator[/LINK] if you need to calculate your actual fuel economy from fill-up data.

Enter Fixed Monthly Costs

Fixed costs stay the same each month regardless of miles driven.Insurance: your monthly car insurance premium.Loan or lease payment: your monthly vehicle finance payment.
Registration and tax: annual fees divided by 12.

Enter Variable Monthly Costs

Variable costs change based on how much you drive.

Maintenance: oil changes, filters, servicing. Estimate $50 to $150 per month for most cars.
Tyres: annual tyre cost divided by 12. Budget $200 to $600 per year depending on vehicle.
Parking and tolls: your average monthly spend on parking and road tolls.
Depreciation: the monthly value your vehicle loses. A rough estimate is 1 percent of vehicle value per month for cars under 5 years old.

Cost Per Mile Formula

The formula is simple. Divide your total monthly operating costs by your total monthly miles driven.

Cost per mile = Total monthly costs / Monthly miles driven

For fuel cost per mile specifically:
Fuel cost per mile = Fuel price per gallon / MPG

Worked Example

  • Monthly miles: 1,500
  • Fuel price: $3.80 per gallon
  • Fuel economy: 25 MPG
  • Monthly fuel cost: (1,500 / 25) x $3.80 = $228
  • Fixed costs:
  • Insurance: $150 per month
  • Loan payment: $400 per month
  • Registration: $20 per month
  • Variable costs:
  • Maintenance: $80 per month
  • Tyres: $30 per month
  • Parking: $50 per month
  • Depreciation: $250 per month

Total monthly cost: $228 + $150 + $400 + $20 + $80 + $30 + $50 + $250 = $1,208

Cost per mile: $1,208 / 1,500 = $0.805 per mile
Fuel cost per mile: $228 / 1,500 = $0.152 per mile
Annual total: $1,208 x 12 = $14,496

IRS Standard Mileage Rate 2026

The IRS sets a standard mileage rate each year for business deductions. For 2026 the rate is 72.5 cents per mile for business travel. This rate covers fuel, maintenance, insurance, depreciation and all other vehicle costs. If your calculated cost per mile is below 72.5 cents, the IRS standard rate is more generous than your actual cost, making the standard method the better choice for tax purposes. If your actual cost exceeds 72.5 cents per mile, you may benefit from tracking actual expenses instead.

What Is Cost Per Mile?

Cost per mile (CPM) is the total expense of operating your vehicle divided by every mile you drive. It captures both what you pay directly (fuel, parking) and the costs that accrue in the background (depreciation, maintenance reserves). Knowing your CPM helps you:

Compare the true cost of vehicle options. A more fuel-efficient car may cost more to finance but less to run. CPM shows you the net position.

Decide whether to drive or use another mode of transportation. If your CPM is $1.10 and a rideshare costs $0.90 per mile, driving costs more for that journey.

Set accurate freight or delivery rates. Owner-operators and couriers use CPM to make sure every mile they drive earns more than it costs.

Claim correct tax deductions. Business drivers can use actual CPM to claim deductions where it beats the standard IRS rate.

Fixed Costs vs Variable Costs

Fixed costs do not change with mileage. You pay them whether you drive 500 miles or 2,000 miles in a month. Insurance, loan payments, and registration are fixed. They make your CPM higher when you drive fewer miles and lower when you drive more miles, because the same fixed cost is spread over more distance.

Variable costs rise and fall with miles driven. Fuel is the clearest example. Drive more miles, and fuel costs rise proportionally. Maintenance and tyre wear also increase with distance.

The more you drive, the lower your fixed cost per mile becomes. High-mileage drivers dilute their fixed costs across more miles, reducing CPM. Low-mileage drivers pay more per mile because fixed costs are spread over fewer miles.

What Percentage Is Fuel of Total Driving Cost?

Fuel represents 15 to 25 percent of total vehicle operating cost for most private drivers. Insurance, depreciation, and loan payments make up the larger share. For owner-operators and commercial trucks, fuel often rises to 30 to 40 percent of total cost because fixed costs per mile are lower at high annual mileage.

AAA data shows the average fuel cost for a new car in 2025 ran 13 cents per mile, while total ownership cost ran $0.77 per mile across 15,000 annual miles. Fuel was 17 percent of the total.

How to Reduce Your Cost Per Mile

Cutting your cost per mile by 15 to 30 percent is achievable for most drivers without changing vehicles. The biggest gains come from improving fuel economy, managing fixed costs, and reducing depreciation through smarter ownership
decisions.

Drive More Miles With the Same Fixed Costs

Your fixed costs stay the same whether you drive 500 or 2,000 miles per month.Insurance, loan payments, and registration do not change with mileage. Adding miles with the same fixed base dilutes those costs across more distance and drops your cost per mile. A driver paying $600 per month in fixed costs at 1,000 miles pays $0.60 per mile from fixed costs alone. At 2,000 miles that same $600 drops to $0.30 per mile. High-mileage drivers always have a natural fixed-cost advantage per mile over low-mileage drivers in the same vehicle.

Improve Your Fuel Economy

Fuel cost per mile drops directly when MPG improves. A car getting 25 MPG at $3.80 per gallon costs $0.152 per mile in fuel. At 30 MPG the same fuel price drops to $0.127 per mile, saving $0.025 per mile. Over 15,000 annual miles that is $375 saved per year from one change alone. Practical actions that improve MPG: maintain correct tyre pressure (adds 0.5 to 3 percent MPG),remove roof boxes and cargo carriers when not in use (saves 5 to 20 percent at highway speeds), drive at 55 to 65 mph rather than 75 mph (saves 10 to 15 percent fuel), and avoid aggressive acceleration and hard braking. Use our fuel cost calculator to see exactly how a 5 MPG improvement changes your annual fuel bill.

Reduce Insurance Cost

Insurance is the second or third largest fixed cost for most drivers. The highest-impact actions: compare providers every year at renewal (switching saves $200 to $600 annually for most drivers), raise your deductible from $500 to $1,000 (reduces premium 10 to 20 percent), bundle with home or renters insurance (saves 5 to 15 percent), and improve your credit score (a 100-point improvement can cut premiums 10 to 25 percent depending on state). Telematics programs that track safe driving through an app or device reward low-mileage and careful drivers with 10 to 30 percent premium reductions. If you drive under 7,500 miles per year, ask about low-mileage discounts which most major insurers offer.

Manage Maintenance Proactively

Reactive repairs cost 3 to 5 times more than preventive maintenance. A timing belt replacement at the scheduled interval costs $400 to $600. A failed timing belt causes engine damage costing $2,000 to $5,000. Sticking to oil change intervals, replacing air and fuel filters on schedule, checking tyre pressure monthly, and addressing dashboard warning lights within a week prevent expensive failures-budget $50 to $150 per month for a typical car under 100,000 miles. A well-maintained vehicle also holds 10 to 20 percent more resale value than a neglected equivalent, which directly reduces effective depreciation cost.

Reduce Depreciation

Depreciation is the single largest cost for most drivers, representing 30 to 40 percent of total ownership cost in the first 5 years. A new car loses 15 to 25 percent of its value in the first year alone. The practical ways to reduce depreciation cost per mile: buy a used vehicle 2 to 4 years old and let someone else absorb the steepest part of the curve, choose models with strong resale values (Toyota, Honda, and truck-based SUVs hold value better than average), keep annual mileage below 15,000 where possible (high mileage accelerates depreciation), maintain the vehicle in good cosmetic and mechanical condition, and keep it for 7 to 10 years rather than trading every 3 years. Every extra year you keep a vehicle after it is paid off eliminates the loan payment from your monthly cost while depreciation slows meaningfully.

Reduce Loan Cost

Your monthly loan payment is one of the largest fixed costs in the breakdown.A $25,000 vehicle financed at 7 percent over 60 months costs $495 per month.At 4 percent over 60 months the same vehicle costs $460 per month. Over 5 years the difference is $2,100. Larger down payments, shorter loan terms, and improving your credit score before applying all reduce monthly loan cost. A 10 percent down payment on a $30,000 vehicle saves $150 to $200 per month compared to zero down at the same rate.

Cut Parking and Toll Costs

Parking and tolls are the most controllable variable cost for urban drivers.Monthly parking in city centers runs $100 to $400. Switching to public transport for commuting and reserving the car for trips where it adds real value cuts this cost to near zero. For drivers who must park, monthly contracts cost 30 to 50 percent less than daily rates at most facilities. On tolled routes, transponders like E-ZPass cut per-toll cost by 20 to 30 percent versus cash and eliminate the time cost of toll plazas.


Cost Per Mile by Vehicle Type

Vehicle TypeTypical Cost Per Mile
Small Car$0.50 to $0.70
Sedan$0.60 to $0.85
SUV$0.80 to $1.10
Pickup Truck$0.85 to $1.20
Semi Truck$1.40 to $2.20
Electric Vehicle$0.40 to $0.80

Cars and SUVs

Average total cost per mile for a new car runs $0.60 to $0.90 at 12,000 to 15,000 annual miles. Smaller cars with good fuel economy and lower insurance sit at the lower end. Large SUVs with high depreciation and fuel costs sit above $0.90. Fuel cost per mile for a typical car at $3.80 and 30 MPG is $0.127 per mile.

Pickup Trucks

Full-size pickup trucks average $0.85 to $1.20 per mile total cost. Higher fuel consumption (16 to 22 MPG for gas trucks, 18 to 24 MPG for diesel) and higher insurance costs push the total up. Commercial use adds wear costs. Diesel trucks used in towing applications benefit from our truck fuel calculator for per-mile fuel costs on specific routes. For farm tractors and agricultural equipment,use our tractor fuel calculator to calculate diesel cost per hour, per acre and per season.

Commercial Vehicles and Owner-Operators

Owner-operators and small fleet operators need to know CPM to price freight profitably. CPM for a semi-truck running 100,000 miles per year runs $1.40 to $2.20 per mile, including fuel, insurance, maintenance, permits, and depreciation. A rate below your CPM on every mile driven means running at a loss. Use our fleet fuel calculator for fuel cost tracking across multiple commercial vehicles.

Electric Vehicles

EV cost per mile for electricity runs $0.03 to $0.07 per mile depending on electricity price and vehicle efficiency. Total ownership cost per mile is similar to or lower than comparable ICE vehicles over a 5-year ownership period due to lower fuel and maintenance costs, but higher upfront depreciation on some models. Our EV vs petrol calculator compares full running costs between electric and fuel vehicles.

Methodology

Frequently Asked Questions

A good cost per mile for a private car at 12,000 to 15,000 annual miles is $0.50 to $0.75 including all costs. The IRS standard mileage rate for 2026 is 72.5 cents per mile, which gives a useful benchmark. Commercial operators aim for CPM below their per-mile rate. Owner-operators on truckload freight need to keep CPM below $1.80 to $2.00 to remain profitable at current rates.

No. Fuel cost per mile covers only fuel. Total cost per mile includes fuel plus all other operating costs. For most private drivers, fuel is 15 to 25 percent of total cost per mile. The difference matters when comparing vehicles, setting rates, or claiming tax deductions.

At $3.80 per gallon and 25 MPG, fuel cost per mile is $0.152. Adding average insurance, maintenance, and depreciation brings total cost to $0.65 to $1.00 per mile for most private passenger vehicles. Commercial trucks run higher.Electric vehicles run lower for fuel but similar in total cost over full ownership.

The five biggest levers are: (1) Drive more miles to dilute fixed costs.(2) Improve MPG through driving style and maintenance. (3) Compare insurance providers annually. (4) Buy used to avoid peak depreciation. (5) Service preventively rather than reactively. Together these can cut CPM 20 to 40 percent for most drivers.
