Commute cost

IRS business rate: 76 cents per mile - Jul 1-Dec 31, 2026. Eligibility and reimbursement rules vary.

Weekly commute cost$58.25

$18.25 fuel plus parking and tolls.

Monthly commute cost$252.42

607 commute miles per month.

All-in monthly proxy$634.40

Uses your all-in cost per mile input plus parking and tolls.

Weekly commute miles140

Round-trip miles multiplied by commute days.

Driving cost estimates change with traffic, route, fuel price, MPG, parking, tolls, return trips, and vehicle wear. Treat the result as trip-planning math.

Formula

Commute cost formula

Weekly fuel cost = round-trip miles x commute days / MPG x gas price; weekly total = fuel cost + parking and tolls

The all-in estimate uses your cost-per-mile input as a broader proxy for vehicle operating cost.

How to use

Steps

  1. Enter total round-trip commute miles.
  2. Enter commute days per week and vehicle MPG.
  3. Add gas price plus daily parking or tolls.
  4. Adjust all-in cost per mile if you want a broader vehicle-cost proxy.

Calculator use

Best for

  • Estimating trip, commute, parking, toll, and fuel costs before choosing a route, schedule, or budget.
  • Comparing driving scenarios with miles, MPG, fuel price, parking, tolls, and commute frequency visible.

Before relying on it

Check first

  • Using ideal MPG when traffic, weather, cargo, terrain, idling, or city driving changes real fuel use.
  • Forgetting parking, tolls, return trips, detours, vehicle wear, or weekly frequency when comparing options.
  • Mixing one-way and round-trip distances or daily and monthly assumptions in the same estimate.

What to know before using the result

Fuel-only vs all-inTwo useful views

Fuel plus parking/tolls shows immediate cash cost. The all-in proxy can include wear, maintenance, depreciation, insurance, and other vehicle costs.

Schedule sensitivityHybrid changes quickly

One fewer commute day per week can materially reduce monthly miles, fuel, parking, and toll costs.

Mileage benchmark76 cents/mile (Jul 1-Dec 31, 2026)

The default is the IRS business rate for the displayed period. The earlier 2026 rate was 72.5 cents/mile for Jan 1-Jun 30, 2026. Use your own vehicle cost or reimbursement rate when appropriate.

Benchmarks

How to read the result

1 - 2 days/week: Hybrid-light.

Fuel and parking costs may be small enough that time cost matters more.

3 - 5 days/week: Regular commute.

Small changes in distance, MPG, gas price, or parking can compound monthly.

$0.76/mile: Jul 1-Dec 31, 2026.

The effective-period IRS business rate can be a broad all-in benchmark, not a personal reimbursement guarantee.

Methodology and assumptions

Formula, inputs, limitations and review record
Formula

Weekly fuel cost = round-trip miles x commute days / MPG x gas price; weekly total = fuel cost + parking and tolls

Inputs used

Round-trip miles, Commute days, Miles per gallon, Gas price, Parking and tolls

Limitations

Trip and commute calculators use the route, frequency, and cost assumptions entered. Real costs can change with fuel price, detours, driving conditions, toll rules, and parking fees.

Intended audience
Commuters comparing a recurring driving-cost scenario from their own round-trip distance, travel frequency, fuel economy, fuel price, and per-mile vehicle-cost assumption.
Valid when
Enter the distance, travel pattern, fuel economy, and prices that apply to the scenario. The IRS option is only a visible comparison reference; parking, tolls, route variation, taxes, reimbursements, and actual ownership costs can materially change the result.
Reliance boundary
This is a planning estimate, not an IRS deduction calculation, tax determination, employer reimbursement rate, accounting record, or measurement of actual vehicle costs.
Data freshness
The 2026 business reference changed from 72.5 cents for January through June to 76 cents for July through December. The shared reference is scheduled for review by November 13, 2026.

FAQ

Common questions

How do I calculate commute cost?

Multiply round-trip miles by commute days, divide by MPG, multiply by gas price, then add parking and tolls.

Does this include maintenance and depreciation?

The fuel estimate does not. The all-in cost per mile field lets you add a broader mileage-cost assumption.

Can I use this to compare jobs?

Yes. Compare monthly commute cost and commute miles alongside salary, schedule, transit options, and time spent commuting.
