Bike commute savings.

Car vs bike commute calculator quantifies long-term savings. 5-mile each way × 5 days × 48 weeks × 0.50/mile car = 600 annual car cost vs 400 bike annual cost = 200/year savings. Plus health benefits, no parking stress, environmental benefit. Lifetime career savings: 6,000 + significant health and quality-of-life value.

Example: 5-mile each way commute (10 miles round trip), 5 days/week, 48 weeks/year. Annual miles 2,400. Car cost 0.50/mile = 1,200/year. Bike annual cost 400 (amortised bike + maintenance + accessories). Annual savings 800. Lifetime career savings 24,000. Plus health benefits worth 200-500/year.

Bike commute reality: (1) Distance limits (under 8 miles practical, e-bike extends 15+). (2) Weather variations 80% days fine, 20% wet/icy). (3) Time differences (city centre cycling often faster than driving in traffic). (4) Shower facilities at work (essential for >3 miles). (5) Equipment investment (300-1,500 quality bike + accessories). (6) Cycle-to-work scheme salary sacrifice 30-40% saving). E-bikes (1,500-4,000): extend distance, reduce sweat, growing adoption. Hybrid: bike summer, train/car winter. Best cycle commute: Zone 2-4, Cambridge, Oxford, York, Bristol cycle infrastructure. Most underrated personal investment for many city workers.

Quick example

With one-way commute miles of 5 and commute days per week of 5 (plus weeks per year of 48 and car cost per mile of 0.5), the result is 800.00. 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 One-Way Commute Miles, Commute Days per Week, Weeks per Year, Car Cost per Mile, and Bike Annual Cost. 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

Annual car cost - annual bike cost = savings. Miles round trip × days × weeks × cost. 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.

Using this without guilt

The figure here isn't a verdict on whether the spending is "worth it". That judgment is yours to make. What the number does is shift the question from "can I afford this?" to "is this what I want my money doing over a decade?". Both questions matter.

What this doesn't capture

The tool prices the money; it can't weigh the enjoyment. A coffee habit, gym membership, or streaming bundle might cost what the math says but deliver value that's harder to quantify. Use the number to make the trade-off visible — the decision is yours.
