Enter the total time you spend seated in a day, the break interval you have chosen yourself and the length of one break. The calculator returns how many breaks fit into that time, how much of the day is break time, and how much net seated time piles up once those breaks are removed. Add the number of seated days and you also get the weekly total.
The method treats one seated block plus one break as a bundle and counts how many complete bundles fit inside the total seated time. That bundle count is the number of breaks, and whatever time is left over becomes the final seated block. As of October 2026 no authoritative standard for how often a seated person should stand up is published, so the interval and the break length are inputs rather than built-in defaults.
This page does not estimate calorie burn or health outcomes, and it does not judge whether your interval is good or bad. If the interval you enter is longer than the whole seated time, the break count is zero and the result says exactly why. If you have lasting back or neck pain, or numbness in the legs, see a clinician before reworking your seated routine on your own.
Frequently Asked Questions
No authoritative standard is published, so this tool recommends nothing. It only counts breaks and totals time for the interval you type in.
It is the total seated time minus the break time that actually fits inside it. With zero breaks, the whole span stays seated time.
Only complete breaks are counted, rounded down. Any partial break left at the end is reported separately in minutes on the last result line.
