Starlink Data Caps Cost Impact Calculator

Compare the cost of staying on Starlink after the cap (paying overages) vs. cutting Starlink at the cap and sending overflow traffic to a cellular link. Adjust assumptions or use plan presets to match reality.

Scope: Single or multi-edge Timeframe: 1–7 years

Inputs & Assumptions

Scenario A: Starlink only (pay overages)

Scenario B: Cap & spill to cellular

Edges e.g. 50 terminals / vehicles

Time horizon (years) 1–7 typical

Starlink Model

Starlink plan preset fills base, cap, overage

Preset details you can still edit values

$165/mo, 500 GB cap, $0.50/GB overage (Business Local 500 GB).

Starlink base / edge / month ($) service fee

High-speed data cap (GB / month) before overages

Overage cost ($ / GB) above cap on Starlink

Avg usage / edge / month (GB) total traffic demand

Cellular Overflow Model

Cellular base / edge / month ($) if any fixed fee

Cellular cost ($ / GB) for overflow data

3-Year Cost Comparison

Starlink only (pay overages) Scenario A

$0 / edge / month

Cap & spill to cellular Scenario B

$0 / edge / month

💡

Switching to cap & spill is neutral in this model.

Adjust assumptions (usage, overage $/GB, cellular $/GB) to explore upside.

Break-even Starlink overage price

No overage traffic at current settings.

All values are directional only. This tool is designed to compare overage behavior rather than provide a formal quote. Use it to show at what point Starlink overages become uneconomical versus sending overflow traffic to a cheaper cellular path.
