Cycling vs driving saves both money and carbon. Typical car running cost 40-60p/mile all-in. Bike: 500-1,500 purchase spread over 5-7 years = 5-10p/mile. Savings per mile 30-50p. Over 4,000 commute miles/year: 1,200-2,000 saved.
How to use it
Input annual commute miles, car cost per mile, annual bike cost (purchase amortised + maintenance), and percentage of days cycling. The tool shows annual savings.
What the result means
Annual savings from cycling share of commutes. Plus health, carbon, often time benefits (no traffic). Many people cycle 50-80% of commutes, keeping car for bad weather.
Quick example
With annual commute miles of 4,000 and car cost per mile of 0.5 (plus bike annual cost of 300 and cycling of commutes of 60%), the result is 900.00. Change any figure and watch the output shift — it's often more useful to see the pattern than to memorise the formula.
Which inputs matter most
You enter Annual Commute Miles, Car Cost Per Mile, Bike Annual Cost, and Cycling % of Commutes. Two inputs usually tip the answer one way or the other. Identify which ones matter most by flipping each value past a round threshold and watching whether the winning option changes.
What's happening under the hood
Miles cycled × car cost per mile = savings. Minus bike annual cost = net. The formula is listed in full below. If the number looks off, you can retrace the calculation by hand — that's the point of showing the working.
Cost vs value in green choices
Sustainable options usually cost more upfront and less over time. This tool separates the two so the comparison is fair — looking at purchase price alone consistently makes the green option look worse than it is once lifetime costs are tallied.
What this doesn't capture
Carbon reduction, health benefits, and local air quality have real value the financial figure doesn't price. The calculation gives the money side honestly; for the full picture, note the non-financial benefits alongside.
Cycling produces annual savings based on the inputs provided.
