Formula
- Speed
- — Average speed for the whole trip, including stops
What is the Trip Time Calculator?
This calculator divides trip distance by average speed to estimate travel time — the key is using a realistic average speed for the whole journey, not just your cruising speed.
How to use it
- 1 Enter the total trip distance.
- 2 Enter your expected average speed, accounting for stops and slower sections.
Worked examples
Limitations
- •Real trips include traffic, rest stops, and speed variation — use a conservative average speed (not your top highway speed) for a realistic estimate.
Frequently asked questions
Should I use my top speed or average speed?
Always use average speed for the whole trip — top speed ignores traffic lights, stops, and slower sections, and will significantly underestimate travel time.
