FWA Business Case Calculator
Model a fixed wireless access business on top of an existing mobile network or a new radio build: capacity, CPE and expansion economics.
Choose whether you reuse an existing 4G/5G network or need new radio infrastructure. The tool then shows the fields that match your starting point and estimates the resulting business case.
Estimated results
S × (1 + G)^M at the end of the forecast period.
Projected subscribers × monthly usage ÷ 1000 (TB).
Busy-hour throughput ÷ (1000 × target utilization).
Capacity you can allocate to FWA, based on your selected starting point.
Required capacity minus available capacity. Zero means your available capacity covers the projected demand.
CEILING(required capacity ÷ usable capacity per site).
Only counted when new radio infrastructure is selected. Reuse scenarios do not build sites.
Projected subscribers × monthly ARPU.
Fixed OPEX + variable cost per subscriber + per-site network operating cost (new build scenarios).
Monthly revenue − monthly operating costs.
Monthly ARPU − variable cost per subscriber, before fixed OPEX.
One-time investment
New sites × investment per site (new build scenarios only).
Capacity gap × expansion cost per Gbps (reuse scenarios).
New subscribers × CPE cost.
New subscribers × installation cost.
Site investment + incremental expansion + CPE + installation.
Break-even cannot be reached: contribution per subscriber is zero or negative. Please review your ARPU and variable cost assumptions.
Monthly fixed cost base ÷ contribution per subscriber.
Not Recovered Within Forecast Period
First forecast month in which cumulative net cash flow turns positive.
Revenue and cost structure
Capacity and subscribers by forecast year
| Year | Projected Subscribers | Required Network Capacity | sites | Monthly Operating Profit | Cumulative net cash flow |
|---|---|---|---|---|---|
| 1 | 26898 | 65.22 | 120 | 485199.97 | 2922843.63 |
| 2 | 36175 | 87.71 | 120 | 693926.68 | 7350383.26 |
| 3 | 48651 | 117.96 | 120 | 974640.89 | 13675733.46 |
Calculation assumptions
Projected Subscribers = S × (1 + G)^M. Monthly Traffic (TB) = Projected × D ÷ 1000 (decimal units, 1 TB = 1000 GB). Average Throughput (Mbps) = Projected × D × 0.003086 (30 days per month). Busy-hour Throughput = Average × B. Required Capacity (Gbps) = Busy-hour ÷ (1000 × R). Required Sites = CEILING(Required ÷ K). When you reuse an existing network, available capacity is the capacity you allocate to FWA and any shortfall is charged at your incremental expansion cost per Gbps. When you build new radio sites, new sites are added as demand requires and each carries its own investment and monthly operating cost. CPE and installation cost apply to every new subscriber. Contribution = A − V. Break-even Subscribers = (O + network OPEX) ÷ Contribution. Payback is simulated month by month until cumulative net cash flow first turns positive; if it does not turn positive within the forecast period, no payback month is shown.
This calculator provides indicative estimates based on your own assumptions. It is not a substitute for detailed radio planning, capacity validation or a formal quotation, and it contains no industry benchmark pricing.
Preliminary Estimate Range
The range below is calculated from the assumptions you entered. Change any input and it updates immediately.
These ranges are planning references calculated from your own inputs. They are not a quotation, an offer or a price list.
The low–high spread is a configurable planning margin used for sensitivity testing. It is a demonstration assumption, not a market benchmark or an IPLOOK price.

Our team can review your requirements and the assumptions used in this calculation, then prepare a tailored estimate for your project.
The detailed cost breakdown (software licence, deployment and integration, customisation, maintenance and support, and architecture options) is not published online. It is prepared by our sales team after a manual review of your requirements.
