Bike vs Car Calculator - Commute Cost and Calorie Comparison

    A 10 km bike commute costs under $30 a month in maintenance. The same route by car: $300-500 with fuel, parking and insurance. Compare both options and see calories burned on top.

    How much does your car commute really cost when a bike covers the same route?

    A 10 km car commute costs $300-500 per month once you add fuel, parking, insurance and service. The same distance on a bicycle: $15-30 per month in maintenance. The gap reaches $4,000-6,000 per year - and you get a free gym membership on top.

    How to compare bike vs car costs - step by step

    1. Step 1: Measure your commute distance
      Open Google Maps, switch to cycling directions and note the one-way distance. The cycling route may differ from the driving route - often shorter through parks and bike lanes. Typical bike commute: 3-15 km one way.
    2. Step 2: Count your commute days
      Standard: 20-22 work days per month. For seasonal cycling (spring through fall), reduce to 15-18 days. Even 8 months of cycling captures 60-70% of annual savings.
    3. Step 3: Enter car costs
      Fuel consumption (check trip computer), fuel price, monthly parking, insurance (annual / 12), and annual service. Do not forget the fixed costs - insurance and service run whether you drive or not.
    4. Step 4: Enter bike costs
      Purchase price (amortized over 4 years) and annual service. A commuter bike at $600 costs $12.50/month in amortization. Add $10-15/month in maintenance. Total: under $30/month.
    5. Step 5: Read the results
      The calculator shows monthly and annual costs, savings percentage, commute time for both options, daily calories burned cycling, and monthly CO2 reduction.

    Cost comparison by distance

    Assumptions: 8 L/100 km, $1.50/L fuel, 21 days/month, $150 parking, $130 insurance, $1,200/year car service, $800 bike over 4 years, $150/year bike service.

    One-way distance Car/month Bike/month Annual savings
    5 km $405 $29 $4,512
    10 km $430 $29 $4,812
    15 km $456 $29 $5,124
    20 km $481 $29 $5,424

    Common mistakes when comparing bike and car costs

    Mistake 1: Counting only fuel. Fuel is just 30-50% of car ownership cost. Insurance, parking, service and depreciation double or triple the real number. Always include fixed costs.
    Mistake 2: Assuming the car is always faster. Under 7 km in city traffic, a bicycle is often faster door to door. No parking search, no traffic jams, direct route through bike lanes.
    Mistake 3: Writing off the bike in winter. Even 8 months of cycling (March through October) captures 60-70% of annual savings. Many cyclists ride year-round with proper gear.

    FAQ - Frequently asked questions

    Does the calculator include car depreciation?
    No. Depreciation adds $2,000-8,000/year depending on the car, which makes driving even more expensive relative to cycling. The calculator covers operating costs only.
    How many calories does bike commuting burn?
    At 18-20 km/h, a 75 kg rider burns about 350 kcal per 20 km round trip. Over 8 months of commuting that is roughly 56,000 kcal - equivalent to 7-8 kg of body fat. No gym required.
    Does an e-bike change the calculation?
    An e-bike costs $1,500-4,000 upfront but charging runs $1-3/month. It extends comfortable range to 20-25 km one way without arriving sweaty. Still far cheaper than a car.
    What is the maximum practical bike commute distance?
    Regular bike: 10-12 km one way (30-40 min). Road bike: up to 20 km. E-bike: up to 25 km comfortably. Beyond 25 km, cycling becomes impractical for daily commuting.
    Can I combine cycling with public transit?
    Yes - the "bike and ride" model works well: cycle to a train station, take the train downtown. Many cities allow bikes on trains. Check the Public Transport vs Car Calculator for the transit cost comparison.
    What about rain and bad weather?
    Waterproof jacket, fenders and lights cover most rain days. Budget $100-200 for rain gear. On truly bad days, take transit or drive - even mixing modes saves $3,000+/year versus driving every day.
