Cost Calculation Formula

The total cost is calculated using the following formula:

Total Cost = (Number of Extensions × Cost per Extension) + Setup Fee

Where:

Number of Extensions - The quantity of phone extensions you need
Cost per Extension - The base cost for each extension (varies by system type and provider)
Setup Fee - One-time fee for configuring the system (varies by provider)

The calculator uses standard pricing models from major US telecom providers. The actual cost may vary slightly based on your specific contract terms and negotiated rates.

Worked Example

Let's look at an example to see how the calculator works in practice.

Example Scenario

You need to add 5 new extensions to your existing business phone system. You're using a hosted PBX system and your provider is AT&T.

Based on standard pricing:

Cost per extension: $25/month
Setup fee: $99 one-time

Using the formula:

Total Cost = (5 × $25) + $99 = $125 + $99 = $224

This means you would pay $224 in total, with $125 going to the monthly extension costs and $99 as a one-time setup fee.

This example shows how the calculator can help you plan your budget for adding new extensions to your business phone system.
