Just like any other field that you might be thinking of looking into, translation often involves charges being decided upon using a sliding scale. If you only need basic information translated, you would likely be able to get this done at a really low rate. That said, in situations where the information that needs to be translated requires technical words and the like, it is important to note that the cost of the translation would start to go up significantly and for good reason.
After all, medical translation would require people to have a medical background as well as an adequate understanding of any and all languages that the translation needs to be done in. At the end of the day, a site like https://phreesite.com/computers-for-medical-translations/ can be enormously helpful here since their computerized translations tend to be a little more affordable as there are no humans that would need to be paid a salary in order to get the job completed and computers are cheaper from a wide range of other perspectives as well most of which are relatively sound.
To answer your question, a medical translation is usually going to cost you approximately 20 cents per word. That means that a 1,000 word medical document will end up costing you around $20 and that is a pretty affordable rate if you think about it. It might go up to $50 as well if the knowledge is highly advanced, but whatever the case may be you would be able to rest assured knowing that the information that you are getting is highly accurate to every single degree. Just make sure that you hire someone that is actually skilled.
