Same. I might have a few ideas in a rough draft somewhere, but nothing close to completion. For 5E, I'd probably say 2 or 3. Going back over the decades, I'm probably up to a dozen or two. It's just not worth the effort unless you're going to play them.I'll sit at the other end of the scale - I don't generally construct characters unless I intend to play them. My ratio is probably pretty close to 1:1.
For many, especially me, making characters is a part of D&D you can play on your own. Often I sit and create new concepts, some conventional and others out there, but in different ways than I see online (minimal powers rather than maxed out). Some of these wind up seeing use as NPCs that have full PC rules behind them. Others just sit in my notebook, or twitter feed, or DnDBeyond to never see the light of day.
Usually I'm the DM, but have played a handful of characters. Recently I did the ratio of created to played characters for myself. It's a big number somewhere around 50:1.
What's your ratio?
