When a phone system starts handling most of your calls, the budget office asks the obvious question: so how many people is that. The obvious answer is wrong.
The tempting math is minutes divided by a workday. Take the deflected calls, multiply by average handle time, divide by eight hours, done. That number is always too low, because it assumes a human answers calls every minute of their shift. Nobody does.
Occupancy and shrinkage
Contact centers plan staffing with two numbers civilians rarely hear.
Occupancy is the share of paid time an agent is actually on calls. Push it too high and people burn out and quit, so centers target something like 60 to 85 percent. Shrinkage is everything that pulls a scheduled person off the phones: breaks, training, leave, meetings, the walk-in at the counter. It routinely runs 30 percent or more.
Stack those and a full-time phone person is truly available to take calls only about 60 percent of the clock. So the real conversion is not deflected minutes divided by an eight-hour day. It is deflected minutes divided by the productive fraction of that day.
Running Sumter's numbers
Sumter County handles 72 percent of roughly 12,000 monthly calls without staff. Convert that deflected volume using realistic occupancy and shrinkage, not a naive workday, and the phone line gives back on the order of five full-time equivalents. Five positions worth of answering, routing, and re-explaining, absorbed by a system that does not take lunch, does not turn over, and answers the tenth simultaneous caller as fast as the first.
Five FTEs is not a rounding error in a county budget. It is a hiring requisition you do not have to post, or a team you can redeploy from reading hours off a laminated sheet to the work that actually needs a person.
The number to bring to finance
Do not walk into a budget meeting with "we saved a lot of hours." Walk in with a defensible FTE figure and the deflection rate behind it, and be ready to show your occupancy and shrinkage assumptions. A finance director will believe five FTEs backed by contact-center math long before they believe "transformational."
For how to frame the whole ask, see making the budget case. To get a deflection estimate for your own volume, book a demo.
