SpaceX Starship Roadmap Lower Launch Costs by 100 Times

Falcon Heavy by SpaceX has a cost per kilogram to LEO of approximately $1,400 per kg. This figure reflects the cost-effectiveness achieved through partial reusability and high payload capacity.

A single use Super Heavy Starship and booster will be able to bring full payloads to orbit for about $250-600 per kilogram. This is with costs of about $90 million and reusable payloads of 200 tons and non-reusable payloads of 300-400 tons.

Initial cost of Super Heavy booster and Starship: $90 million

Fuel and maintenance cost per flight: $2 million

Number of reusable flights: 6

Total cost for 6 flights:

90,000,000+(2,000,000×6)=102,000,000

Payload Capacity

Starship payload to orbit: 200 tons per launch

Total payload for 6 launches: 200 tons × 6 = 1,200 ton

The cost per kilogram to orbit using the SpaceX Starship under these conditions is approximately $93.66/kg even if payload is 180 tons it would still be $94.

5-6 full reuses would get the cost below $100/kg

For 6 Flights:

With 200 tons payload: $93.66 per kg

With 240 tons payload: $78 per kg

For 20 Flights:

With 200 tons payload: $32.50 per kg

With 240 tons payload: $27.08 per kg

For 50 Flights:

With 200 tons payload: $19.00 per kg

With 240 tons payload: $15.83 per kg
