ETA Calculator — Estimated Time of Arrival & Task Completion

ETA Calculator — Estimated Time of Arrival & Task Completion. Free ETA calculator. Enter total items, your processing rate, and start time to instantly calculate estimated time of arrival, total duration, and remaining time.

Calculate your estimated time of arrival or task completion time with our free ETA calculator. Enter the total items to process, your processing rate, and the start time — get instant results.

How to Use the ETA Calculator Enter the total amount to process (items, bytes, pages, etc.). Set your processing rate (e.g. 5 plates per 3 minutes). If you are already partially done, set the percentage complete slider.

Read the total duration, end time, and remaining time instantly. Practical Examples Download ETA: 1,000 MB at 10 MB/s = 100 seconds. Data processing: 10,000 records at 500 records/minute = 20 minutes. Print job: 200 pages at 20 pages/minute = 10 minutes.

Frequently asked questions

How do I calculate the estimated time to finish a task?

Enter the total number of units to process, set the start date and time, then enter the rate: how many units are done in how many milliseconds, seconds, minutes, hours or days. The total duration and the finish time counted from your start time update immediately.

How long will 500 items take at 5 items every 3 minutes?

Enter 500 as the amount and 5 in 3 minutes as the rate. The tool divides 500 by 5 and multiplies by 3 minutes, so the total duration is 5 hours, and it shows when you will finish counted from your start time.

How do I account for work that is already done?

Move the Percentage already done slider. The remaining duration becomes the total duration multiplied by the share still to do, and the ETA below it is that remaining time counted from now. The slider does not use the time that has passed since the start.

Can I estimate how long a download or file copy will take?

Yes. Enter the file size as the amount, for example 2000 for 2000 MB, and the speed as the rate, for example 25 in 1 with seconds selected. The total duration shows how long the transfer takes at that constant speed.
