Cost breakdown
Formula
car cost = distance × days × (L/100 km ÷ 100) × fuel price + parking × days= 167.916
Note
This is a simplified model. It applies the stated arithmetic to the figures you enter and ignores inflation, taxes, seasonal variation, interest and any local rules. Use it as a rough guide, not as financial advice.

What costs should I include on the driving side of the comparison?+
Include fuel based on your commute distance and vehicle's fuel economy, plus parking fees, tolls, and a reasonable share of maintenance and insurance tied to commuting mileage — fuel alone usually understates the true cost of driving.
Does this account for the value of my time?+
The base calculation compares direct monetary cost only; if transit takes noticeably longer than driving, you should weigh that time difference separately, since it's a real cost but not one measured in dollars by default.
Why is driving often more expensive than it feels day to day?+
Costs like insurance, depreciation, and maintenance are paid periodically rather than at the pump, so they don't feel connected to each individual commute, even though they're a direct consequence of the miles you drive to work.
How does a monthly transit pass change the comparison?+
An unlimited monthly pass has a fixed cost regardless of how many trips you take, so the more you ride, the lower your effective cost per trip — compare the pass price against your total monthly driving cost rather than a single trip's fare.
What if I only commute by car part of the week?+
Prorate both sides of the comparison to the actual number of commuting days rather than a full month, and consider whether a hybrid approach — transit some days, driving others — beats committing fully to either option.
