Commute Calculator — Time, Distance & CO₂
Find out how many hours a year you spend commuting, how far you travel, and what CO₂ you produce — before deciding whether a shorter route or remote work is worth it.

Daily round-trip time
30 × 2 = 60 - 2
Weekly commute time
60 × 5 = 300 - 3
Annual commute minutes
300 × 48 = 14,400 - 4
Annual commute hours
14,400 ÷ 60 = 240
How does this calculator work?
Annual commute hours = one-way minutes × 2 × days-per-week × weeks-per-year ÷ 60. CO₂ is yearly kilometres × an emission factor per km (car ≈ 171 g/km, train ≈ 41 g/km, cycle = 0). Useful for deciding whether to negotiate remote days or move closer to work.
Formula
How this is calculated
The calculator doubles your one-way commute time to get the daily round-trip, then multiplies by your weekly working days and the number of weeks you actually work per year (subtract holidays and remote days) to get the total annual commute time in hours.
Distance follows the same logic: one-way distance is doubled, then multiplied by days per week and weeks per year to give total kilometres driven or travelled per year. Average speed is simply one-way distance divided by one-way travel time in hours.
CO₂ estimates use 2023 UK Department for Energy Security and Net Zero average emission factors per passenger-kilometre: car 171 g, motorbike 114 g, bus 89 g, train/metro 41 g, bicycle and walking 0 g. These are national averages; your actual footprint depends on vehicle type, occupancy and energy source. The commute time as a share of a working year is based on 1,920 hours (48 weeks × 5 days × 8 hours).
Frequently asked questions
The tool labels the distance field "km" — enter your distance in kilometres and the CO₂ factors will be correct. If you commute in miles, multiply by 1.609 first. Speed and distance results will be in km and km/h.
They are indicative averages. Car emissions vary widely by engine size and fuel type (a small petrol car emits ~120 g/km, a large SUV ~200+ g/km). Electric vehicles are not zero but much lower than petrol averages. Treat the figure as a ballpark for comparison.
A full-time worker with four weeks of holiday commutes roughly 48 weeks per year. Deduct any weeks you work fully remotely for a more accurate annual total.
