Frequently asked questions
What formula does this tool use for the daily saving?
This tool uses saving per day = round-trip fuel cost + parking + (office lunch − home lunch) + coffee. Round-trip fuel cost is 2 × distance ÷ km per litre × price per litre. With the defaults of 20 km, 12 km per litre and 1.80 per litre that is 6.00 of fuel, plus 10.00 parking, 8.00 lunch difference and 5.00 coffee, a total of 29.00 a day.
How are the weekly and annual savings calculated?
Weekly savings are the daily saving times commute days per week. Annual savings are the daily saving times commute days per week times work weeks per year. The default 5 days and 48 weeks give 240 commute days a year, so 29.00 × 240 = 6,960.00. Holidays and leave are covered only through the weeks you enter.
How is time saved estimated?
The tool assumes an average commute speed of 40 km/h and a round trip, so time per day = 2 × distance ÷ 40 hours. At 20 km that is 1 hour a day, or 240 hours over 240 commute days. The speed is fixed, so a slow or fast commute is not captured; scale the distance if you want to adjust for it.
What is the “equivalent hourly value of time saved”?
It is annual money savings divided by annual hours saved, which is 6,960.00 ÷ 240 = 29.00 per hour with the defaults. It describes how much you keep per commuting hour avoided, which is not a wage or an opportunity-cost estimate. With a distance of zero there are no hours saved and the figure shows 0.00.
How is CO₂ avoided calculated?
The tool uses a fixed 170 grams of CO₂ per km for the whole round trip: 2 × distance × commute days a year × 170 ÷ 1000, shown in kg. With the defaults that is 1,632 kg a year. The 170 g/km figure is a flat assumption in the code and is not adjusted for your vehicle, so treat the result as a rough illustration.
What happens if I enter zero in a field?
A zero is used as a zero. A distance of 0 removes fuel cost and time saved; parking of 0 removes parking; a home lunch cost of 0 makes the lunch saving equal the full office lunch price. Clearing a box counts as 0, so an emptied field never reverts to its starting value (20 km, 5 days, 1.80 fuel, 12 km per litre, 10 parking, 12 and 4 for lunch, 5 coffee, 48 weeks). Two fields cannot be 0: vehicle fuel efficiency, because fuel use is distance divided by km per litre, and work weeks per year, because the annual figures need at least some working weeks. With either one at 0 the tool shows a message asking for a value above 0 instead of a result. Values between 0 and 1 for those two fields are held at 1.
What is not counted?
Vehicle wear and depreciation, insurance, tolls, public transport fares, home electricity or internet, and the cost of working from home are not included. The whole coffee cost counts as a saving because there is no field for coffee at home. If your office lunch costs less than your home lunch the lunch line is negative and reduces the total. Distances can be entered in miles as long as fuel efficiency uses the same unit, but the speed and CO₂ assumptions remain per kilometre.
Remote work savings: the arithmetic of a skipped commute
Building the daily saving
The tool prices one avoided commute day and then scales it. Fuel is the round trip (twice the one-way distance) divided by your km per litre, times the price per litre. Parking is a flat daily cost. Lunch counts only the difference between the office price and the home price, while the coffee or drink cost counts in full. Summing these four gives the saving per day, which is multiplied by commute days per week and by work weeks per year. Everything else on the page is derived from the distance and day count.
Worked example: the default commute
With a 20 km one-way trip, 5 days a week and 48 weeks, the daily saving is 29.00, made up of 6.00 fuel, 10.00 parking, 8.00 lunch and 5.00 coffee. Weekly savings are 145.00, annual savings 6,960.00, annual time saved 240 hours and CO₂ avoided 1,632 kg. A lighter case, 35 km one way, 3 days a week, 46 weeks, fuel at 2.10 per litre and 10 km per litre, free parking, lunch 14 against 5 and coffee 4, gives 3,822.60 a year, 83.10 a week and 242 hours.
Four commutes compared
The table repeats the calculation for four sets of inputs, each shown in the first column; the first and third rows use the defaults apart from the stated change. The final row has equal office and home lunch costs, no parking and no coffee, so only fuel remains. The zero-distance row is useful because it shows what the other three daily costs still contribute when there is no driving at all.
| Inputs | Per day | Annual savings | Hours saved | Value per hour saved |
|---|---|---|---|---|
| Defaults (20 km, 5 days, 48 weeks) | 29.00 | 6,960.00 | 240 | 29.00 |
| 35 km, 3 days, 46 weeks, fuel 2.10 at 10 km/L, free parking, lunch 14 vs 5, coffee 4 | 27.70 | 3,822.60 | 242 | 15.83 |
| 0 km, otherwise defaults | 23.00 | 5,520.00 | 0 | 0.00 |
| 10 km, 2 days, 50 weeks, fuel 1.50 at 15 km/L, no parking, no coffee, lunch 8 vs 8 | 2.00 | 200.00 | 50 | 4.00 |
Reading the time and carbon figures
Time saved comes from a flat 40 km/h assumption and carbon from a flat 170 g per km, both applied to the round trip. They scale only with distance and days, so two people with the same distance get the same figures regardless of traffic or vehicle. In the 10 km, 2-day example that gives 50 hours and 340 kg. Use them as relative indicators and not as measurements of your own commute.
Limits of the estimate
The tool measures only the costs it has fields for. It does not subtract costs that remote work adds, such as heating or a better internet plan, and it leaves out car wear, insurance and tolls that would raise the savings. Hybrid schedules can be modelled by lowering commute days per week. For a decision, add your own home-working costs to the result and keep the lunch and coffee assumptions honest.
