Cubesats and femto-sats are a nice place for universities and small enterprises to set their sights on. There are a number of sources of hardware and software (some even available at reasonably low prices), but outside of specific projects (launch many at once together) I can't seems to find any accurate price model. Data please!
1$\begingroup$ Can you clarify your question? Are you asking about the costs of building a cubesat (as it appears from your question body) or about the costs of launching one (as suggested by the title). These are related questions, obviously, but have very different answers. $\endgroup$– Adam WuerlDec 20, 2014 at 18:51
4$\begingroup$ Just launch costs. $\endgroup$– ThePlanManDec 21, 2014 at 9:27
1$\begingroup$ @ThePlanMan in that case you should accept superdesk's answer as his presents more relevant information than mine. $\endgroup$– ForgeMonkeyMar 24, 2015 at 15:42
Launching a CubeSat is by their nature a difficult process. They are designed as a secondary payload, which means that the primary payload dictates the entire launch.
There are some programs such as NASA's CubeSat initiative, which provide free rides to educational projects.
For commercial launches, data is spotty. One CubeSat reportedly launched for 100k (OSSI-1). One company charges about 300k for a 3u (Space Flight Services). So 100k per Unit seems like a good ballpark. Both quotes are for LEO.
Recently many CubeSats have been shipped to the ISS, and then released from there with the NanoRacks deployer. However, there have been some problems with the launcher (Discover news article).
There have been a few proposals of small rockets designed to just launch CubeSats, but as far as I know none of these have come to fruition.
The bottom line is that CubeSats are by design just catching a ride, so there is no real price model or launching service.
$\begingroup$ In the late 2020s quite few companies aimed at specializing at CubeSat launches. Rocket Lab may be the best one, with Astra Space and others following them. $\endgroup$– KozuchFeb 7, 2021 at 14:33
Edit: This answer was written before the question was clarified to specifically address launch costs, and as such does not fully answer the question.
There's a good price breakdown/analysis on SatMagazine for some generic numbers. However, it was written in 2009 so may be a little out of date.
You might also take a look at Clyde-Space, they have a lot of products with clear pricing, and more importantly no ITAR restrictions. Here's another good list of potential component suppliers.
I'm sure there's better data out there, but that's the best I know of. Hope it's helpful.
$\begingroup$ The question, as clarified in the comments, is specifically about launch costs, which I couldn't find information about on either the Clyde-Space or cubesat links. Those sites are about satellite costs. And cost numbers from 2009 aren't going to be very useful, as too much has evolved since then in the secondary payload market. $\endgroup$ Dec 21, 2014 at 18:59
