Drive Cost Calculator

Calculate your driving cost

No sign-up required. The example values are illustrative, not live fuel prices. Replace them with your current pump price and actual vehicle fuel economy.

How to calculate the cost of driving

1. Enter a journey distance and choose one-way or return trip.
2. Enter measured fuel economy in the units shown for your country.
3. Enter the price you actually pay for fuel. The calculator estimates fuel consumed and multiplies it by price.
4. Multiply journey cost by the number of trips per month for a monthly fuel budget.

Formula for each country

US and Imperial gallons are different sizes. Do not enter US mpg in the UK Imperial-mpg field without converting it. Fuel economy varies with traffic, road conditions, temperature, tyre pressure and vehicle condition.

Driving cost calculator: find the fuel expense for your journey

Use this drive calculator when you want to know how much it costs to drive between places or travel a fixed distance. The same calculation works for a short commute, a weekend road trip or a daily work journey. Your measured mileage and local pump price determine the result.

Cost to drive calculator for gas or petrol

In the USA, a gas cost calculator uses miles, US miles per gallon and USD per US gallon. In the UK, a petrol calculator uses miles, Imperial mpg and GBP per litre. Canada's fuel consumption calculator commonly uses kilometres and L/100km; Pakistan's petrol cost calculator uses kilometres and km per litre. Changing the country above sets the correct input units.

Trip cost calculator and journey fuel cost calculator

A trip cost calculator estimates fuel consumed across a chosen distance. A journey cost calculator works the same way: fuel needed multiplied by the price of that fuel. For a return trip, choose the return option; if the input is already the complete round-trip distance, use one-way to avoid doubling it.

Cost per mile and monthly driving costs

For an illustrative US vehicle achieving 30 US mpg at $3.50 per US gallon, fuel alone costs about $0.12 per mile and $11.67 for 100 miles. At the same rate, 20 separate 100-mile trips cost about $233.33. These are fuel-only estimates, not total ownership or reimbursement rates. Driving conditions and current fuel price can change the result.

For vehicle-wide expenses beyond a gas trip, see car running cost, monthly fuel allowance, and trip fuel expenses.

Office commute and monthly driving expenses by country

Estimating the cost of driving to work? Our dedicated office commute calculators use each country's local currency and fuel-economy units, and show daily and monthly fuel expenses. Enter your actual travel distance, work days and pump price; these are planning estimates, not employer reimbursement entitlements.

Common questions

How much does it cost to drive 100 miles?

For an illustrative USA vehicle doing 30 US mpg at $3.50 per US gallon, 100 miles consumes about 3.33 gallons and costs approximately $11.67 in gasoline. Replace these sample rates with real-world figures; this is not a live fuel quote.

Does this drive cost calculator include vehicle maintenance?

No. It calculates fuel or petrol cost only. Total cost of driving also includes servicing, tyres, depreciation, insurance, parking, tolls and financing. Explore car running costs for broader budgeting.

Is the return trip twice the one-way cost?

With unchanged distance, efficiency and fuel price, yes. Terrain, traffic and driving speed may differ on the return, so treat it as an estimate.

Can I compare electric and petrol vehicles?

This tool calculates liquid fuel costs. For electric charging and hybrid comparisons, use the EV charging cost calculator and petrol versus EV cost comparison for Pakistan.
