About this calculator
A focused variant of distance-from-time: you know remaining distance, you know current speed, you want time-to-arrival. Use mid-trip when GPS may not be available, or as a cross-check.
Frequently asked
Should I use posted speed or current speed?+
Use whatever you can actually maintain — current cruising speed if traffic is moving, posted limit if you're sitting still.
How accurate is this for the rest of a trip?+
Within 10% on open highway. Less accurate near urban areas where traffic is volatile.
My GPS says different — why?+
GPS uses current traffic conditions and accounts for upcoming slowdowns. Static math just divides distance by speed.
What if I'm stopped?+
Speed = 0 makes time infinite. The calculator returns "—" for zero or negative speed.
Does this apply to flights?+
Yes — but factor in tailwind/headwind separately. Cruising speed for a 737 is ~510 mph, not what your GPS records during ascent/descent.
