Calculator
What one window costs to coordinate.
With your numbers, and the arithmetic in the open.
This calculator does one thing: it multiplies the coordination hours you actually spend by your own loaded hourly cost, and shows how much of that can be removed. It does not know what you will save — nobody does. What it does is let you change every assumption and see immediately how much the answer depends on it.

How much the answer rests on one assumption
The same arithmetic at three different reduction assumptions plus the one you chose. If the spread is wide, that is what you need to know before putting the number in front of a board.

How this is calculated
The full arithmetic, line by line
- base hours = windows × people × hours each
- reschedule overhead = windows × reschedule share × people × hours each × reschedule cost
- hours today = base hours + reschedule overhead
- hours after = hours today × (1 − reduction)
- hours saved = hours today − hours after
- annual saving = hours saved × hourly cost
- FTE = hours today ÷ 1,800
- net saving = annual saving − licence cost
- payback in months = licence cost ÷ (annual saving ÷ 12)
There is no hidden coefficient and no value supplied by us. Every number in the arithmetic is one of the fields above.
What this model does not know
The whole calculation runs in your browser. Nothing is sent to our servers and nothing is stored anywhere. The share link encodes the numbers in the URL itself, so even that does not pass through us.
- We hold no customer measurement of the reduction share, which is why it is a field rather than a constant. If it looks optimistic to you, lower it and watch what happens.
- Loaded hourly cost is your estimate. The default is a starting point, not a market figure.
- This counts coordination hours only. It makes no attempt to price risk, a regulatory penalty or reputational damage.
- Hours saved is not automatically money saved. In most organisations those hours move to other work rather than removing a headcount.
- Onboarding, training and ongoing administration are not included. Ask for them in the quote.
- Host count does not enter the money arithmetic. It sizes the quote, and the quote is the number we do not publish.
Is the number big enough to talk about?
If it is, we would happily walk it with you and say which of your assumptions look high to us. If it is not, that is a good answer and it did not need a meeting.
- The numbers you entered never reached us. If you want us to see them, send the link.
