Timeline Update Time Saved Calculator

Estimates how many hours a year a planner spends re-sending revised run-of-show timelines to vendors one by one, and what a single shared live timeline would save in hours and dollars.

Estimates only. Assumptions are listed below, and you can change every input.

Every event timeline changes several times before the day, and each change has to reach the caterer, DJ, photographer, florist, venue and rental company. When that happens by editing a document, exporting a PDF and emailing or texting each vendor, then chasing them to confirm they got it, the cost is spread across so many small moments that nobody notices it. Added up over a season it is real time, and it is also where old versions slip through.

This calculator multiplies your events per year by revisions per event and vendors per event, then by the minutes it takes you to update and confirm a single vendor. That is your manual update time. It then estimates the time with a shared live timeline as revisions times the minutes to edit the timeline once, since every vendor sees the same version. The difference is the hours saved, which is priced at the hourly value you enter. Every number is yours; the tool bakes in no industry averages.

How to use this tool

  1. Enter how many events you run in a year and how many vendors typically need the timeline for each one.
  2. Estimate how many revisions go out per event and time yourself on the next one: minutes to update and confirm one vendor manually, and minutes to make the same change once in a shared timeline.
  3. Enter your hourly value and read the hours and dollars saved. Use the percentage to sanity-check whether the change is worth a new habit for your team.

What the math assumes

  • Manual update time is events times revisions times vendors times the minutes per vendor you enter; every vendor takes the same time on every revision.
  • Shared timeline time is events times revisions times the minutes per revision you enter, on the assumption that one edit reaches every vendor without separate sends.
  • The dollar value is hours saved multiplied by your hourly value; it does not include software cost, setup time or the cost of mistakes from outdated versions.
  • If the shared-timeline minutes are higher than the manual total, hours saved and the reduction percentage go negative rather than being hidden.
  • Time to answer vendor questions about a change is not modelled in either scenario, so the comparison is only about distributing the update.

Frequently asked questions

Is six minutes per vendor per revision a realistic default?

It is only a placeholder. Time yourself on your next revision from opening the document to receiving the last confirmation, divide by the number of vendors, and replace the default with that.

Does a shared timeline really mean zero time per vendor?

No, and the tool does not assume that. The minutes per revision input is the time to make and check the edit once; if you also send a quick heads-up message to vendors, add those minutes to that input.

Should I count day-of changes as revisions?

Yes, and they are usually the most expensive ones because they happen under pressure and reach vendors by phone. If day-of changes take longer per vendor than pre-event ones, raise the minutes per vendor to a blended average.
