Fact or Fantasy

You would have to save $2,500 per year to get $25,000 in 10 years.

Please discuss this and if you disagree with it, let me know how long you think it takes to get $25,000 or how much you would have if you were to save $2,500 in ten years. You have to make some assumptions(interest rates and other economic variables) so let me know what the assumptions are as well.
