Starlink Capex per Subscriber: Why Reuse Changes the Payback Math
Starlink's payback period per subscriber has collapsed as Falcon 9 reuse drove launch cost per kilogram to LEO down by an order of magnitude.
Capex per sub (FY21)
~$2,800
Capex per sub (FY25)
~$1,150
Implied payback
<14 months
Why per-sub capex is the right metric
Starlink capex spans satellites, ground gateways, user terminals (subsidised at point of sale), and the launches that put satellites in orbit. Dividing total Starlink-attributable capex by net subscriber adds in each fiscal year gives a per-sub capex figure that has fallen from ~$2,800 in FY21 to ~$1,150 in FY25.
Two drivers: V2-mini and Gen 3 satellites carry roughly 4× the capacity per unit mass, and Falcon 9 reuse pushed dedicated Starlink launch cost per kilogram below $1,000 — well under the $5,000+ price quoted to external customers.
Payback math
At $1,150 capex per sub and average gross profit of ~$85/month, the payback period sits under 14 months. That is genuinely best-in-class telecom economics and explains why Starlink is willing to keep subsidising terminal hardware to grow installs.
Key takeaways
- Per-sub capex has fallen ~60% in four years driven by reuse and bigger satellites
- Sub-payback is now under 14 months — best-in-class telecom unit economics
- Falcon 9 internal launch cost is the key sensitivity for Starlink margins
