POTS Replacement Savings Calculator
Estimate monthly and annual savings from replacing legacy analog POTS lines across multi-location restaurant and retail portfolios. Model payback on cellular or managed POTS replacement.
Who it's for: CFO · Operations · IT Director · Facilities
Key Insight
This calculator estimates monthly and annual savings from replacing legacy analog POTS lines across your portfolio. Enter location count, lines per site, current and replacement monthly costs, and one-time implementation spend. Compare monthly savings, payback period, and three-year net savings.
Why this tool exists
POTS bills keep rising but nobody has a portfolio-wide inventory. Facilities knows alarms still use copper. IT gets carrier notices about line retirement. Finance wants a business case before approving replacement hardware.
This calculator turns those questions into a shared savings estimate. It is not a vendor quote. Actual savings depend on line inventory accuracy, alarm vendor requirements, and replacement technology choices.
Should you use it?
You should evaluate this if:
- You still pay for copper or analog lines at multiple locations
- Carrier retirement notices or rising POTS bills created urgency
- Alarm, fax, elevator, or emergency phones still depend on analog lines
- Leadership wants payback math before a POTS replacement project
Probably not if:
- You completed POTS replacement across the portfolio in the past year
- You have fewer than two analog lines and no planned openings
- You have not validated which systems each copper line supports
How to Use It
Enter the number of locations and average analog lines per site. Include alarms, fax, elevator phones, emergency lines, and other copper dependencies—not just voice extensions.
Use your blended monthly POTS cost per line for current spend. Enter the estimated replacement monthly cost for cellular gateways, managed POTS replacement, or other alternatives.
Add one-time implementation cost for hardware, installation, and project coordination. Results show monthly savings, annual savings, payback period, and net three-year savings.
What the Results Mean
Current monthly POTS cost is total lines multiplied by current per-line cost across the portfolio.
Estimated replacement monthly cost applies the replacement per-line rate to the same line count.
Monthly savings is the difference between current and replacement recurring cost.
Payback period divides one-time implementation cost by monthly savings. Three-year savings subtracts implementation cost from cumulative monthly savings over 36 months.
Reality check
Savings estimates assume accurate line counts and replacement costs validated with alarm vendors and local code requirements. Life-safety systems may need vendor-approved alternatives before cutover.
