Car vs. Bike Comparison Calculator

The true cost of car commuting extends well beyond fuel. Gas costs are the most visible, but maintenance (tires, oil, brakes), depreciation (each mile reduces the car's value), insurance, parking, and tolls all add to the per-mile cost. The IRS standard mileage rate of $0.67 per mile (2024) reflects this total cost. Even counting only fuel and direct commute-related maintenance, driving costs about $0.15-0.25 per mile. Bicycle commuting costs are dramatically lower. A reliable commuting bicycle costs $300-1000, lasting 5-10 years with maintenance. Annual maintenance (tires, chains, tune-ups) runs about $100-200. This translates to about $0.02-0.05 per mile, roughly one-tenth the cost of driving. CO2 emissions from a typical passenger car are about 404 grams per mile (EPA average). Over a 10-mile round trip commute, 250 days per year, a car emits about 1,010 kg (over 1 metric ton) of CO2. A bicycle produces no direct emissions. Even accounting for the additional food calories a cyclist burns (and the CO2 associated with food production), cycling produces about 90% less CO2 than driving. Health benefits of cycling commuting are substantial. A 5-mile bike commute at moderate pace burns about 200-300 calories each way, depending on terrain and intensity. Over a year of commuting, this equals about 100,000-150,000 calories, equivalent to losing 28-43 pounds of body fat (if diet remains constant). Regular cycling commuters have lower rates of cardiovascular disease, diabetes, and all-cause mortality. Travel time is often cited as the barrier to bike commuting, but in urban environments with traffic congestion, cycling can be competitive with driving for distances under 5 miles. The average car commuter spends about 26 minutes each way (including traffic), while a cyclist covers 5 miles in about 25 minutes at moderate pace. For distances over 10 miles, e-bikes extend the practical range while maintaining most of the benefits. Safety is the most significant concern for potential bike commuters. Infrastructure matters: cities with protected bike lanes, low-speed streets, and connected bike networks have much higher cycling rates and lower accident rates. Visibility gear, helmets, and route selection are essential safety measures.
