ETA Calculator
Enter total work, completed work, and a steady rate to estimate the remaining time and expected finish time locally.
A QUICK WALKTHROUGH
How to use this tool
- Enter the total work units and how many units are complete.
- Enter your current speed and choose whether it is measured per minute, hour, or day.
- Calculate the estimate and copy the remaining time, finish time, and progress.
A simple progress estimate
The calculator subtracts completed units from total units, converts your rate to units per minute, and divides the remaining work by that rate. It also shows the percentage complete and a finish time based on the current device clock.
Use a steady observed rate
ETA is only as reliable as the rate you enter. Use a recent average when work speed changes, and recalculate when progress or throughput changes.
Private browser calculation
Your values and the estimate are processed in your browser. Nothing is uploaded or stored by this page.
GOOD TO KNOW
Common questions
What does ETA mean?
ETA means estimated time of arrival. Here it is the estimated time until the remaining work is complete.
Can completed units equal total units?
Yes. The calculator reports zero time remaining and marks the work complete.
Can I use minutes, hours, or days?
Yes. Choose the unit that matches the speed you measured.
Is the finish time a guarantee?
No. It assumes your current rate stays steady and should be refreshed when the rate changes.
