VoIP cost savings calculator

Enter what you pay today and we'll estimate what the same usage would cost on business VoIP — using the blended per-user pricing we see in real quotes across 200+ providers. Planning rates from live deployments, not teaser promo rates.

How this calculator works

We model your VoIP cost from blended per-user pricing observed in real quotes: $15–30/user/month depending on team size, plus a modest uplift if you regularly call internationally (even the best plans meter most international routes, though 8x8 includes 14 countries free). Your savings are the difference against your current spend — we show the full modeled difference alongside a conservative estimate; where your final contracted rate lands depends on feature tier, term length and negotiation.

What it doesn't include: one-time hardware (though most providers include phones at commitment or support BYOD softphones), implementation labor for complex multi-site moves, and taxes/fees which vary by jurisdiction. Treat the number as a planning estimate — then let competing quotes make it precise.

Where the savings actually come from

• Line charges collapse — per-line analog/PRI billing becomes per-user pricing with calling included.
• Maintenance ends — PBX service contracts and move/add/change technician visits become admin-portal changes.
• Long distance shrinks — domestic calling is included; international rates drop 50–90%.
• Tool consolidation — conferencing, fax lines and SMS platforms often fold into one subscription.

The honest caveats — and how to avoid them — are in our full cost-savings analysis. The biggest single lever isn't the provider you pick; it's making providers compete. See our negotiation playbook for how that works.
