Commute Cost & Time Calculator

How Commute Cost & Time Calculator Works

A commute's daily cost and time feel small in isolation, but multiplied by every working day of the year they represent a real chunk of both your budget and your life. This calculator scales a single day's driving cost (or transit fare) and commute time out to monthly and yearly totals, so the true size of the trade-off is visible.

Formula & Method

For driving, cost per km is fuel price divided by fuel efficiency (km per liter), and daily cost is that rate times the round-trip distance (one-way distance × 2) plus any extra daily cost like parking or tolls. For transit, daily cost is simply the one-way fare doubled plus extras. Either way, daily cost and daily time (one-way time × 2) are multiplied by days per week and weeks per year to get yearly totals, which are then divided down to monthly and daily figures, and yearly time is also expressed in hours and full 24-hour days.

Worked Example

With the defaults (15km one-way, fuel at 100/liter, 15 km/liter efficiency, 35-minute one-way trip, 5 days/week, 48 weeks/year): cost per km is 100 ÷ 15 ≈ 6.67, daily cost is about 200 (30km round trip × 6.67), yearly cost is 200 × 240 days = 48,000, and monthly cost is 4,000. On the time side, the 70-minute round trip adds up to about 280 hours a year -- roughly 11.7 full days spent commuting.

Frequently Asked Questions

Why does "weeks per year" default to 48 instead of 52?

52 weeks assumes you commute every single week of the year with no exceptions -- 48 builds in a rough allowance for public holidays, annual leave, sick days, and work-from-home days, which is more realistic for most people. Adjust it up or down to match your actual routine.

Why is the distance or fare doubled?

The distance and fare fields ask for a one-way trip, but a commute is a round trip -- the calculation doubles both the distance (for driving) and the fare (for transit) to account for the return leg, since forgetting this would understate cost and time by roughly half.

What should I put in "Extra Daily Cost"?

Anything recurring that isn't captured by fuel or fare -- parking fees, toll charges, or a bike-share/rideshare leg that bridges the last mile. It's added once per day (not doubled), so if a cost only applies one-way, enter half of it, or the doubled full amount if it applies to both legs.

How is "yearly days commuting" different from days per week times weeks?

That stat converts your total commuting time (in hours) into 24-hour days, not workdays -- it's a way of expressing "how much of a continuous year, if you added up every minute spent in transit, would this consume," which tends to be a more visceral number than hours alone.
