The Apollo program cost roughly $20.6 billion for spacecraft, launchers and mission operations (1960–1973), rising to $25.8 billion when facilities and overhead are included. Adjusted to 2025 CPI, the core bill is about $189 billion; including Project Gemini and robotic lunar efforts raises the historical total to about $28 billion (≈$280 billion in 2025). The program spanned 17 missions, produced six Moon landings and left enduring scientific legacies such as a working lunar retroreflector and the 'moon trees'.

How Much Did NASA's Apollo Program Really Cost the United States?
Neil Armstrong's famous line marked an extraordinary achievement — and a major national investment. Between roughly 1960 and 1973, the core Apollo program (spacecraft, launch vehicles, development and mission operations) cost about $20.6 billion. When ground facilities, personnel pay and overhead are included, that historical total rises to approximately $25.8 billion.
Adjusted to 2025 dollars using the Consumer Price Index, the core Apollo expenditures equal about $189 billion. If you widen the accounting to include Project Gemini and the robotic lunar program that preceded Apollo, the historical total reaches roughly $28 billion, which converts to about $280 billion in 2025 dollars.
What the money bought
The investment supported 17 Apollo-era missions, from the Apollo 1 tragedy in 1967 through Apollo 17 in December 1972. The program achieved six crewed lunar landings (Apollos 11, 12, 14, 15, 16 and 17) and delivered lasting scientific and cultural legacies: for example, the Apollo 11 retroreflector array still in use to measure the Earth–Moon distance, and the so-called 'moon trees' grown from seeds flown on Apollo 14.
Roots and technology
Earlier efforts — Project Mercury and Project Gemini — were essential testbeds that developed the procedures, hardware and human skills used in Apollo. The Apollo vehicle itself consisted of three parts: the command module (CM), the service module (SM) and the lunar module (LM). At the time this configuration represented cutting-edge engineering, and it remains an iconic technical accomplishment given that humans have not returned to the lunar surface since Apollo.
Measured purely in dollars, Apollo was a major national investment; measured in scientific, technical and cultural returns, it remains one of the most consequential programs in modern history.
Quick facts:
- Core Apollo (1960–1973): ~$20.6 billion historically; ~$189 billion in 2025 dollars (CPI-adjusted).
- Including Gemini and robotic programs: ~$28 billion historically; ≈$280 billion in 2025 dollars.
- Missions: 17 Apollo-era missions, 6 crewed lunar landings, final crewed mission Apollo 17 in December 1972.
