Public Transport vs Driving Calculator

Compare the yearly cost of a commute by car and public transport. Use the full round-trip distance, commuting weeks, parking costs and the ticket or pass you would actually buy.

How to use Public Transport vs Driving Calculator

1. Choose the currency used for results. 2. Enter round-trip distance and cost per selected mile or kilometre. Match the public-transport fare period to the ticket or pass, then enter the days, weeks or months you would pay for. 3. Change a value to update the results, or select Calculate. Review the chart and notes with the total. 4. Use Copy results, Share results or Download result graphic to keep the answer. Shared links include your figures. 5. Reset restores the editable example inputs.

Why use this tool?

A commuting comparison can change when you include parking or choose a season ticket. It also depends on whether the car would be kept anyway. A fuel-only comparison answers a different question from deciding whether you could give up owning the car. The calculator gives you control over that distinction through the extra ownership-cost field. Enter avoidable costs for a change in routine, or include the wider annual ownership amount if that is the decision you are considering. Time, convenience and service reliability remain separate from the price result.

How the calculation works

Annual commute days = days per week × commute weeks. Driving cost = commute days × (round-trip distance × energy cost per distance + daily parking and tolls) + included annual ownership costs. Daily transport fares are bought on commute days; weekly passes use commute weeks; monthly passes use the entered paid months; an annual pass is bought once. Other annual public-transport costs are added separately. Monthly results are annual totals ÷ 12. The distance selector labels your input; it does not convert a cost-per-mile figure into a cost per kilometre.

Example

For a 30-mile round trip at £0.15 per mile, plus £6 parking, each driving day costs £10.50. Five days a week over 46 weeks gives £2,415. Daily public-transport fares of £8 over the same 230 days cost £1,840: a £575 yearly difference before any entered ownership or other travel costs.

Practical tip

Include the last part of the journey, such as a bus connection or station parking, rather than comparing a complete drive with only one part of the public-transport route.
