Posting Time Calculator

Manual group posting has a hidden price tag. Put in your numbers and see what tab-hopping really costs you every month.

Manual posting means opening each group, pasting, attaching media, and waiting — about 4 minutes per post at your pace.

How the math works

Every manual post to a Facebook group costs the same tax: open the group, wait for it to load, paste your caption, attach photos, click post, and move to the next tab. At 20 groups and 4 minutes each, that's over 80 minutes per campaign — before scheduling, tracking, or retries.

Automation flips the equation: the writing happens once, group selection is a checklist, and pacing runs itself with conservative delays between posts. Your remaining job is reviewing progress, not performing it.

Posting time questions, answered

We multiply your posts per week by the minutes each manual post takes (opening the group, pasting, attaching media, waiting), scaled to a 4.33-week month. Four minutes per post is a realistic average for tab-hopping across groups.
