I don't know of an age given. The first date I know is Troughton at 450. The general progression is about 100 years per regeneration (which does not work when you measure it in companions, but oh well) which puts Hartnell about 300. But Wikipedia notwithstanding, Romana is ~130, and Susan is certainly much younger. She is definitely a child, whereas Romana is clearly an adult. (Romana has completed University and possibly an advanced degree in Doctor Studies, while highschool is appropriate for Susan). There's also at least one generational difference between her and the, as noted, quite young Doctor. We can maybe estimate a timelord generation between 100 and 150 years (given Romana as a model). That would put Susan definitely within her first century, and make the number 15 actually not that unreasonable.
Also, we don't know anything about the maturation process. Is the age of majority proportional to lifespan, or do they simply have much shorter childhoods? (I don't know how Elves and Dwarves work in Tolkien, as examples of other longevitous beings, but Hobbits seem to split the difference with the age of majority at 33 and extended teenage years - Pippin is such a spoiled rich kid).
So the long and the short of it is, depending on how we think timelords (or whatever she is) mature, I could put Susan anywhere from 15 to maybe 30 or 40.
