That will be hard to explain in English but you can find what you're paying to French healthcare system by looking at your paycheck (the document you receive every month that detail your paycheck rather). It basically either 7% or 13% of your paycheck (and .5% of non-work income via the CSG), and you have a hard cap on total contributions (4k/month, and healthcare if a bit more than half of that, so a bit more than 2k/month). It cover universal healthcare of course , but also maternity/paternity leave and invalidity benefits.

Paternity/maternity also cover the pension parents get (half a year of contribution to the pension system per child if you take care of them til they are 13, plus half a month for giving birth) (that's so awkward explaining this in English, sorry)
