Cycling vs Driving Savings Calculator

Cycling vs driving savings calculator compares cumulative savings from replacing car trips with cycling. 5 miles/day × 250 days × 0.50/mile car cost = 625 annual car cost avoided. Cycling 400 annual cost. Net savings 225/year. Over 30 years: 6,750. Plus health benefits, no parking, no congestion charges.

Example: 10 miles/day cycling, 250 days/year (work commute) = 2,500 annual miles. Car cost 0.50/mile (typical AA estimate including depreciation, insurance, fuel) = 1,250 annual driving cost replaced. Cycling 400 annual cost. Net savings 850/year. 10-year savings 8,500. Lifetime (30 years) 25,500.

Cycling commute reality: requires shower facilities, weather management, security (theft), time (often slower than car for short trips, faster for congested cities). Best for: city commutes (3-10 miles), young/healthy commuters, environmentally motivated, fitness-focused. Worst for: long commutes (15+ miles), bad weather areas, heavy cargo needs, multi-stop trips. Cycling commute growing 25% post-COVID. Cycle Hire (Santander Cycles) 2/day - even cheaper option.

A worked example

Try the defaults: daily cycling miles of 10, cycling days per year of 250, car cost per mile of 0.5, annual cycling cost of 400. The tool returns 850.00. You can adjust any input and the result updates as you type — no submit button, no reload. That's the real power here: seeing how sensitive the output is to one or two assumptions.

What moves the number most

The result responds to Daily Cycling Miles, Cycling Days per Year, Car Cost per Mile (£), and Annual Cycling 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 option with the lower calculated total changes.

The formula behind this

Annual miles × car cost per mile - cycling annual cost = net savings. Everything the calculator does is shown in the formula box below, so you can check the math against your own spreadsheet if you want.

Why see the number at all

Small recurring spending is invisible by design — every individual transaction is forgettable. Compounded over years, the total often surprises. Seeing the figure doesn't mean you typically need to cut the spending; it just makes the trade-off conscious.

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.
