How much is your commute really costing you?
Money, time and the working days you spend just getting there
How do you commute?

Introduction
The cost of commuting is one of the most consistently underestimated items in a household budget. It is not a single line item most people track. It arrives as a season ticket renewed twice a year, or as a petrol station visit that feels like a driving cost rather than a commuting cost, or as insurance that seems fixed regardless of whether you use it to drive to work or not.
When the components are added together – travel, fuel, parking, wear and tear, insurance apportioned to commuting – and then multiplied by the number of working days in a year, the figure is often larger than people expect. And when the time cost is added – the hours per year spent on platforms, in traffic, on replacement bus services – the true cost of commuting starts to look like a significant proportion of total working life.
This calculator adds it all up. It handles five commuting modes: train, car, bus, mixed, and walk or cycle. For car commuters it calculates from miles and fuel rate rather than a daily cost, since most drivers do not know what their daily commute costs but do know how far they drive. For everyone, it converts the annual time cost into working days and working weeks – the unit that makes the number land.
The WFH nudge at the bottom is intentional. At a time when return-to-office requirements are being actively discussed, knowing that one extra day at home per week saves approximately £X per year and reclaims Y hours is a concrete figure worth having.
How to use this calculator
Select your commute mode. Train, car, bus, mixed, or walk/cycle. Car switches the input to miles and fuel rate rather than a daily cost. Walk and cycle set the cost to zero but still calculate the time.
Enter your daily cost. For train, bus and mixed commuters, this is the return daily fare – divide your season ticket cost by the number of working days it covers if you have an annual or monthly pass.
For car commuters: enter your daily round-trip mileage, your fuel cost per mile (typically 14 to 20p for most petrol cars depending on fuel price and efficiency), and any daily parking costs.
Enter your one-way commute time in minutes. The calculator doubles this for the return journey.
Set the slider to your days in the office per week. If you work from home some days, set this to reflect your actual office days rather than five.
Enter your gross annual salary. This enables the “days paying for your commute” figure – how many working days of gross pay go purely to the cost of getting to work.
Frequently asked questions
How many working days does the calculator use?
The calculator uses 46 working weeks per year – 52 weeks minus approximately six weeks for bank holidays, annual leave and typical absences. Multiplied by your days per week in the office, this gives your total commuting days per year. You can adjust indirectly by changing the days-per-week slider.
What is included in the car commute calculation?
The car commute mode calculates fuel cost from your daily mileage and fuel cost per mile, plus any daily parking charges. It does not automatically include insurance, servicing, depreciation or road tax – these are harder to allocate specifically to commuting and vary significantly by vehicle. If you want to include them, you can add an approximate daily allocation and enter it as a parking cost, or switch to the manual daily cost entry by using the mixed mode instead.
The HMRC mileage rate for 2024/25 is 45p per mile for the first 10,000 miles, which represents the full cost of using a car including fuel, wear, insurance and depreciation. If your employer pays you mileage at this rate, you are already being reimbursed for the full cost. The calculator defaults to 16p per mile – approximately the fuel-only cost for an average petrol car – because most private commuters are not reimbursed at the full HMRC rate and want to see the cash cost rather than the total economic cost.
How is the “days paying for your commute” figure calculated?
It divides your total annual commute cost by your daily gross salary (annual salary divided by 251 working days). The result is the number of working days of gross pay that go to the cost of getting to work. At a typical commute cost of £2,500 per year on a £35,000 salary, that is approximately 18 working days – nearly four working weeks of gross pay spent on commuting.
This framing is more vivid than a monthly or annual cost because it expresses the commute in terms of work already done. The money has been earned; the question is whether that is a reasonable portion to allocate to getting to the place where you earn it.
Why does the walk and cycle mode show a cost?
It shows zero financial cost but still calculates the time. Walking or cycling to work does not cost money in the way driving or taking the train does, but it still costs time. A 30-minute each-way cycle commute five days a week produces 230 hours per year of commuting time – the same time cost calculation applies regardless of the financial cost.
Whether that time counts as exercise rather than dead time is a legitimate argument for active commuting that the calculator does not attempt to resolve. The time figure is there for completeness and comparison.
What counts as a mixed commute?
Mixed means any combination of modes – drive to the station, train to the city, walk to the office; bus plus walking; cycling to the bus stop; and so on. For mixed commutes, use the train/bus mode and enter the combined daily cost of all legs. The time input captures the total door-to-door one-way time.
Is a season ticket more cost-effective than daily tickets?
Almost always, yes – annual season tickets typically cost around 40 weeks of daily fares, meaning you save the cost of roughly 12 weeks of travel on a full-year pass. The saving on a monthly season ticket is smaller but still typically 5 to 10% compared to daily fares. For this calculator, use the equivalent daily cost of your season ticket (divide the total by your working days in the period) to get an accurate annual figure.
What does working from home one extra day per week actually save?
The green nudge panel at the bottom calculates this specifically for your inputs. For a typical train commuter spending £12.50 per day, working from home one extra day saves approximately £575 per year in travel costs and reclaims around 90 hours of commuting time – over two full working weeks. For car commuters with a long drive, the savings can be considerably higher.
