Trip Time Calculator
Estimate door-to-door driving time by pairing your route distance with a realistic average speed and explicit delay minutes for stops, fueling, meals, and recurring congestion.
Designed for drivers, fleet planners, and dispatchers who need transparent, physics-based time estimates in hours and minutes rather than optimistic best cases.

Methodology
Core kinematics applies time = distance ÷ average speed; keep distance and speed in the same unit system (miles with mph or kilometers with km/h) for valid hours output.
Base driving time excludes interruptions; planned delays are converted from minutes to hours and summed to yield a more realistic total trip time.
Outputs are provided in hours and minutes so you can compare against operating policies, delivery windows, or duty-hour limits.
F.A.Q.
What average speed should I enter?
Use the speed you realistically sustain on the route, not the posted limit. Urban corridors, work zones, weather, or heavy vehicles justify lower averages than free-flow interstates.
How do I account for traffic or checkpoints?
Add those minutes into planned delays. Include recurring congestion, toll or border queues, refueling, meals, and rest breaks to align with planning-time reliability.
Does this handle unit conversions automatically?
No. Keep distance and average speed in the same system—miles with mph or kilometers with km/h—so the hours output remains correct.
Why include rest breaks?
Safety research links long uninterrupted driving and fatigue to higher crash risk. Scheduling short breaks helps maintain alertness and compliance with duty-hour guidance.

Semantic versioning
- MAJOR: Calculation outputs can change for the same inputs (formula, rounding policy, assumptions).
- MINOR: New features or fields that do not change existing outputs for the same inputs.
- PATCH: Bug fixes, copy edits, or accessibility changes that do not change intended outputs except for previously incorrect cases.
Review protocol
- Verify formulas and unit definitions against primary standards or datasets.
- Run golden-case regression suite and edge-case suite.
- Record reviewer sign-off with credentials and scope.
- Document assumptions, limitations, and jurisdiction applicability.
Assumptions & limitations
- Uses exact unit definitions from the Fidamen conversion library.
- Internal calculations use double precision; display rounding follows the unit's configured decimal places.
- Not a substitute for calibrated instruments in regulated contexts.
- Jurisdiction-specific rules may require official guidance.
