Gandalf arrived in Middle Earth at the beginning of the Third Age so he’s been around in that form for about 3000 years since Bilbo’s farewell party took place in the 3001st year of the Third Age. The Fellowship was founded in 3018 so Gandalf is about that old if we’re only counting his time in Middle Earth like you say
Edit: This is in part why people are upset with the Rings of Power show. If this not-Gandalf character ends up being Gandalf, he’ll have arrived in Middle Earth about 5000 years too early. On top of that there are just a lot of other timeline deviations, including the order of the forging of the rings which you would imagine the whole show to be about.
