There is no publicly disclosed current price per Starship launch or verified current cost to SpaceX per flight in the primary sources cited here. SpaceX’s prominent Starship cost figures are future targets, not a price quote. Historical Falcon 9 and Falcon Heavy figures can provide context, but they do not reveal what a Starship launch costs today.
What does a Starship launch cost?
No current Starship per-launch price or internal cost per flight is disclosed in the primary evidence cited here. NASA lists Starship among launch services vehicles, and SpaceX has made it eligible under a NASA launch-services program; neither establishes a commercial price or repeatable operating cost.
In its 2026 prospectus, SpaceX says it aims to reduce the cost of reaching orbit by “99% or more relative to the historical average launch cost.” That is a company-stated future goal, not a measured Starship launch cost or customer quote. SpaceX’s May 2026 roadshow deck also describes a propellant-only marginal-cost goal for airline-like operations; a propellant-only target is not the full cost of a launch.

| Figure | What it describes | How to interpret it |
|---|---|---|
| $18,500 per kilogram | NASA historical average for 1970–2000, as attributed by SpaceX’s 2026 prospectus. | A historical benchmark, not a current launch price. |
| About $2,700 per kilogram | NASA’s approximate figure for the first version of Falcon 9 in 2010; NASA’s 2018 technical paper reports about $2,720/kg using a $62 million advertised price and 22,800 kg payload assumption. | A historical comparison tied to the early Falcon 9 and the paper’s stated assumptions, not a current quote for every mission. |
| About $1,400 per kilogram | First-version Falcon Heavy in 2018, as reported in SpaceX’s 2026 prospectus using NASA as its source. | A historical cost-per-kilogram comparison, not a current price for all Falcon Heavy missions. |
| About $94 million | NASA’s 2018 firm-fixed-price Falcon 9 contract for Sentinel-6B, including launch services and other mission-related costs. | A customer contract value for a defined mission scope, not the bare rocket price or SpaceX’s internal cost. |
| 99% or more reduction (goal) | SpaceX’s 2026 target for reducing the cost to reach orbit against the historical average launch cost. | A future corporate target, not a measured Starship cost or current price. |
Why cost per launch and cost per kilogram are not interchangeable
A per-launch figure may be a customer price for a particular mission or a provider’s internal cost. A per-kilogram figure divides a cost or price by payload mass, but the result depends on what mass is actually delivered and to which orbit. A rocket’s theoretical payload capacity is not necessarily the mass used in a specific mission, so a per-kilogram comparison needs its performance assumptions as well as its date and vehicle configuration.
Contract scope matters too. The Sentinel-6B figure covers launch services and other mission-related costs. It cannot be treated as a bare rocket price, and it says nothing by itself about the provider’s internal or marginal cost.

What these comparisons can—and cannot—tell you
- They show historical context: NASA-derived figures put the early Falcon 9 and Falcon Heavy well below the cited 1970–2000 historical average on a per-kilogram basis.
- They do not price Starship: No current Starship launch price or current internal cost per flight is disclosed in the cited primary evidence.
- They do not create a current rocket price list: NASA’s overview covers vehicles including Falcon 9, Falcon Heavy, Electron, New Glenn, Vulcan, and Starship, but does not provide a common current schedule of prices.
- Program eligibility is not pricing: NASA added Starship to SpaceX’s Launch Services II offerings through a contract modification dated March 28, 2025; that establishes eligibility, not a disclosed launch price.
