What is the cheapest way to launch a small satellite?

For payloads under a few hundred kilograms, a rideshare slot on a large rocket (such as SpaceX Transporter) is usually cheapest, at roughly $6,000 per kilogram with a ~50 kg minimum. A dedicated small launcher like Rocket Lab Electron costs more per kilogram but gives you control of the orbit and schedule. The calculator on this page compares both for any payload mass.

Q: How much does it cost to launch a rocket?

It varies enormously by vehicle. A SpaceX Falcon 9 has a list price near $69.75 million, or roughly $3,000 per kilogram at its maximum payload to low Earth orbit (and as low as ~$2,700/kg with a reused booster). A Rocket Lab Electron costs about $7.5 million for 300 kg (~$25,000/kg). Rideshare slots start near $6,000/kg with a ~50 kg minimum. SpaceX Starship targets under $100–200 per kilogram once fully reusable. Use the calculator on this page to price a specific payload.

Q: Why did SpaceX make launch so much cheaper?

Three factors: booster reusability (landing and reflying the first stage removes most of the per-flight vehicle cost), vertical integration (manufacturing components in-house instead of using subcontractors), and high cadence (launching every few days spreads fixed costs across many more flights). Together these drove a roughly 10x cost reduction versus comparable expendable rockets.

Q: How much cheaper will Starship make launch?

SpaceX targets a fully reusable Starship carrying 100–150 tonnes to LEO at a marginal cost that could push price-per-kilogram below $100–200 — a further 10–30x reduction from Falcon 9. These are design goals, not achieved prices; real costs will depend on refurbishment, cadence and how SpaceX prices commercial flights.

Payload to low Earth orbit

List prices in 2025 USD; a dedicated launch books the whole rocket regardless of how much capacity you use. Reused boosters and negotiated contracts are often cheaper. Rideshare ≈ $6,000/kg (≈50 kg minimum). Estimates marked ~.

The 90% Cost Collapse

The cost of reaching orbit is the single most important number in the space economy — it sets the price of everything above it, from broadband constellations to space stations. For decades it barely moved: roughly $10,000–$54,000 per kilogram to low Earth orbit, keeping space the preserve of governments and the largest operators.

Reusable rockets broke the barrier. SpaceX landed the first orbital-class booster in December 2015 and has since reflown Falcon 9 first stages hundreds of times. Combined with high cadence and in-house manufacturing, that pushed cost-per-kilogram below $3,000 — about a 90–95% reduction from the Shuttle era — while Falcon 9 grew to fly the large majority of the world's commercial launches.

The next step-change is Starship: a fully reusable super-heavy vehicle designed to carry 100–150 tonnes to LEO. If rapid reuse with minimal refurbishment works, marginal cost-per-kilogram could fall below $100 — a change that would redraw what is economically possible in space.

What Cheap Launch Unlocks

Mega-constellations. Starlink would have been impossible at 2010 prices; at current Falcon 9 costs, deploying ~60 satellites per flight is viable. Amazon Leo (Kuiper), Guowang and Qianfan all depend on continued low costs.

Commercial stations, tourism, in-space manufacturing. Axiom and Orbital Reef, orbital tourism, and microgravity production only close their business cases if transport stays cheap. Crew Dragon already cut the cost of a seat to orbit to a fraction of the Shuttle's.

Methodology & sources

Per-vehicle figures are published list prices divided by maximum stated LEO payload, in 2025 USD — a like-for-like upper bound. Real prices vary with booster reuse, rideshare and negotiated contracts. The estimated launch spend YTD multiplies each provider's live launch count by a representative per-launch list price; it is a directional estimate, not audited revenue. Live launch counts, cadence and market share are computed from Orbital Radar's launch database; orbital object counts from our live catalogue.

Launch Cost FAQ

How much does it cost to launch a rocket?

It depends on the vehicle. Falcon 9 lists near $69.75M (~$3,000/kg at max payload, ~$2,700/kg reused). Rocket Lab Electron is ~$7.5M for 300 kg (~$25,000/kg). Rideshare slots start near $6,000/kg with a ~50 kg minimum. Starship targets under $100–200/kg once fully reusable. Use the calculator above to price a specific payload.

Under a few hundred kilograms, a rideshare slot (e.g. SpaceX Transporter, ~$6,000/kg, ~50 kg minimum) is usually cheapest. A dedicated small launcher like Electron costs more per kilogram but gives you control over orbit and schedule.

Why did SpaceX make launch so much cheaper?

Booster reusability, vertical integration (in-house manufacturing) and very high cadence — together a roughly 10x reduction versus comparable expendable rockets.

How much cheaper will Starship make launch?

SpaceX targets 100–150 tonnes to LEO at a price that could fall below $100–200/kg — a further 10–30x cut from Falcon 9. These are design goals, not achieved prices.
