How to calculate
Compare two one-way commute times over the active days you actually travel.
Annual time saved =
(before-after)*trips*days/60 hTime saved per active day =
(before-after)*trips minEquivalent 8-hour days =
(before-after)*trips*days/480Worked example
- Previous one-way time (min): 45
- New one-way time (min): 30
- One-way trips per active day: 2
- Active commute days per year: 220
- Annual time saved: 110 h
- Time saved per active day: 30 min
- Equivalent 8-hour days: 13.75
Assumptions and limits
Enter active travel days rather than every calendar day. Negative savings mean the new journey takes longer. Reliability, cost and work during travel are excluded.
Results are rounded for display; calculations use unrounded values. Read our calculation methodology.
Understanding the result
Compare two one-way commute times over the active days you actually travel. A 15-minute saving on each of two daily trips over 220 days is 110 hours per year.
When this tool is useful
A 15-minute saving on each of two daily trips over 220 days is 110 hours per year.

Frequently asked questions
What assumptions should I check?
Enter active travel days rather than every calendar day. Negative savings mean the new journey takes longer. Reliability, cost and work during travel are excluded.
How can I check the result?
Start with the labelled example. Keep units consistent, calculate without intermediate rounding and change one input at a time. The diagram explains the model; the result table supplies the numerical answer.
