The Cost Of Fuel For Spacex Launches

how much does fuel cost spacex per launch

SpaceX has come a long way since its founding in 2002, with the private aerospace company becoming the first commercial rocket company to launch humans into orbit in 2020. With the Falcon 9 launch vehicle, SpaceX has achieved a high launch cadence, with 498 successful launches as of 2024. The costs of these launches are estimated to be between $15 million and $28 million internally, with the second stage of the rocket being the largest expense at $12 million per unit. SpaceX's launch costs are substantially lower than NASA's, with the Falcon 1 and Falcon 9 development costs estimated at $390 million total. With the introduction of the Autonomous Flight Safety System (AFSS), SpaceX has further reduced costs and increased launch flexibility.

SpaceX's internal costs for a Falcon 9 launch

The price of a Falcon 9 launch has increased over the years, keeping pace with inflation. The initial advertised price for commercial satellite launches using the v1.0 version in 2010 was $49.9–56 million. By 2012, the price had risen to $54–59.5 million, followed by $56.5 million for the v1.1 version in 2013 and $61.2 million in 2014. The Full Thrust version in 2016 was priced at $62 million, while the Block 5 version in 2024 reached $69.75 million. Government contracts typically involve higher prices, as determined through competitive bidding processes. For example, Dragon cargo missions to the ISS cost $133 million under a fixed-price contract with NASA.

SpaceX has become the leading provider of rideshare launches due to its frequent launch cadence and competitive pricing. The Falcon 9 has been noted for its reliability and high launch cadence, with 498 successful launches, two in-flight failures, one partial failure, and one pre-flight destruction. It is the most-launched American orbital rocket in history. The rocket has two stages: the first (booster) stage, which is reusable, carries the second stage and payload to a predetermined speed and altitude, and the second stage, which is not reusable, accelerates the payload to its target orbit.

The development costs of the Falcon 9 rocket were estimated to be approximately $390 million in total, according to NASA's independently verified numbers. The NASA contract for three demonstration launches of Falcon 9 with the SpaceX Dragon cargo spacecraft was initially awarded $278 million, but additional milestones increased the total contract value to $396 million. The Falcon 9 v1.0 development costs were estimated to be around $300 million by SpaceX in 2011.

Cost of the second stage

The Falcon 9 rocket has two stages. The first stage, known as the booster, carries the second stage and the payload to a predetermined speed and altitude. The second stage then accelerates the payload to its target orbit. While the first stage can be reused, the second stage cannot and is believed to be the largest expense per launch. SpaceX's COO stated that each second stage costs $12 million to produce.

The cost of the second stage can be attributed to various factors, including the cost of the rocket, fuel, infrastructure, organisation, staffing, and development. The cost of fuel for a SpaceX launch can range from $300,000 to $2 million. However, it's important to note that fuel costs are just one component of the overall launch costs.

The high cost of the second stage can be partly explained by the fact that it is not reusable. Reusing components is a significant factor in reducing launch costs. SpaceX has achieved efficiencies in its launch costs, estimated between $15 million and $28 million per Falcon 9 launch, by reusing first-stage boosters and payload fairings.

SpaceX is working to reduce the cost of launches by increasing the reuse of components and improving efficiency. The company plans to make the Starship 20% longer and improve its engines, potentially increasing the payload capacity to 200-250 tons in reusable mode. By reducing fuel, operations, and maintenance costs, SpaceX aims to lower the future payload cost to $15 per kilogram.

Additionally, SpaceX's Super Heavy Starship can further reduce costs. A single-use Super Heavy Starship can bring the cost down to about $150 per kilogram, while high reuse of the vehicle can decrease the cost to $10-20 per kilogram. However, it is important to distinguish between internal costs and the prices charged to customers, which tend to be significantly higher.

Cost of rocket and fuel

The cost of a rocket launch depends on various factors, including the size and type of the rocket, the payload capacity, and the launch provider. Orbital rockets, for instance, are significantly more expensive than suborbital rockets, with costs varying according to their purpose.

SpaceX's Falcon 9 rocket, a partially reusable, two-stage-to-orbit, medium-lift launch vehicle, is priced at US $67 million as of 2025. This price has increased over the years, keeping pace with inflation. The advertised price for commercial satellite launches using the v1.0 version in 2010 was $49.9–56 million, which rose to $54–59.5 million by 2012. SpaceX charges about US $55 million per seat for crewed launches. The Falcon Heavy, a heavy-lift version of Falcon 9, costs US $90 million, rising to US $150 million if expended.

SpaceX's internal costs for a Falcon 9 launch are estimated to be between $15 million and $28 million, including workforce expenses, refurbishment, assembly, operations, and facility depreciation. The second stage, which is not reused, is the largest expense per launch, costing $12 million to produce.

The cost of rocket fuel is just one component of the overall launch cost. The launch cost includes all direct and indirect manufacturing costs, associated overhead, recurring engineering, sustaining tooling, and quality control. There are also infrastructure, organisation, staffing, and development costs to consider.

According to a Reddit user, SpaceX's internal cost per kg to Low Earth Orbit (LEO) is estimated to be around $1000/kg, with external partners paying significantly more. However, it is important to note that these estimates may not include all the associated costs of a launch.

Cost of infrastructure, organisation, staffing, and development

SpaceX was founded in 2002 by Elon Musk with the goal of decreasing the cost and improving the reliability of access to space. Headquartered in Hawthorne, California, the company has since grown to a workforce of 9,500 employees, with an annual revenue of $2 billion.

SpaceX's development and launch of its Falcon 1 rocket, an expendable two-stage-to-orbit small-lift launch vehicle, cost approximately $90 million to $100 million. The company's success with Falcon 1 led to the development of the Falcon 9 and Falcon Heavy rockets, with the latter being built from three Falcon 9 boosters. Falcon 9 has been launched and landed more than 450 times as of May 2025, with 1-3 launches per week. This has brought much-needed investment to SpaceX, allowing it to diversify its income sources.

The development of the Dragon spacecraft, which began in 2005, further solidified SpaceX's position in the industry. In 2006, NASA awarded SpaceX $396 million to provide crew and cargo resupply demonstration contracts to the International Space Station (ISS). SpaceX has also been awarded contracts by the US military, with the Falcon 1 launches purchased by the US Department of Defense under the DARPA Falcon Project.

In 2014, SpaceX won nine out of 20 contracts competed worldwide, impacting the market for the launch of US military payloads, which had previously been dominated by the United Launch Alliance (ULA). This monopoly had allowed launch costs by the US provider to rise to over $400 million. SpaceX's ability to offer competitive pricing and its success in the market have been attributed to its development of reusable rocket technology, which has significantly reduced the cost of space travel.

Cost per kg to LEO

The Falcon 9 rocket, designed and manufactured by SpaceX, has been noted for its reliability and high launch cadence. It is a partially reusable, two-stage-to-orbit, medium-lift launch vehicle. The Falcon 9 has had 498 successful launches, two in-flight failures, one partial failure, and one pre-flight destruction. It is the most-launched American orbital rocket in history.

The cost per kg to LEO for Falcon 9 has been estimated at $3600/kg for an unrecovered launch and $4400/kg for a recovered booster launch. The Falcon 9 wiki page states a reusable Falcon 9 costs $62 million for 9600 kg to LEO, which equates to $6460/kg. However, it is important to note that these numbers are fairly artificial as the Falcon 9 could never launch 18 tons of payload without some rework on PAF design and qualification.

The price of reaching LEO has traditionally been in the $10,000 to $100,000 per kg range. However, with the advent of SpaceX, the price has been plummeting. The Falcon 9 delivers to LEO for $2800/kg, Falcon Heavy for $1400/kg, and Starship with a projected $50/kg.

SpaceX's internal costs for a Falcon 9 launch are estimated between $15 million and $28 million, factoring in workforce expenses, refurbishment, assembly, operations, and facility depreciation. These efficiencies are primarily due to the reuse of first-stage boosters and payload fairings. The second stage, which is not reused, is believed to be the largest expense per launch, with each costing $12 million to produce.
