The answer to your question varies widely. . What kind of paint? House, car, boat, masonry? Interior or exterior? Lawn furniture or lawn mower? A clean, well prepared surface....or not? As a general rule the better prepared a surface is the more durable and longer lasting the paint will be.
If you had two small pieces of 2x4 and painted the first one with exterior paint then set it outside in direct sunlight. The second one you lightly sanded with 60 or 100 grip sandpaper, wiped all the sanding dust off of it`and then applied a coat of exterior primer, let it dry and then paint it with exterior paint. The paint on the prepared (prepped) piece of wood could last indefinitely. While the paint on the hastily painted first piece would begin to degrade rather quickly in comparison.
The sun and an unprepared surface are the most common reasons for paint failure.
