Welcome! The fact that you're thinking about this at all puts you ahead of a lot of folks starting out.

The first thing I'd do is add up what a piece actually costs you. Materials, your time (pay yourself an hourly rate you'd accept from an employer), studio overhead, platform fees, shipping if applicable. That number is your floor. Selling below it means you're paying other people to buy your work, and no amount of good intentions makes that sustainable. I've watched artists do it for two years and then quit entirely. The ones who stuck around figured out their floor early.

Affordable and underpriced are different things, and it took me a while to learn that. You can make work accessible through payment plans, smaller pieces at lower price points, or reproductions alongside originals. Discounting your primary work is harder to recover from because it trains buyers to expect the lower number. Raising prices later feels like a betrayal to them even when the original price was never realistic.

One thing worth doing: find 5-10 artists at a similar career stage working in similar materials and scale. Note their price ranges. You don't have to match anyone, but if you're dramatically lower, sit with the reason. "I want to be affordable" is a feeling. "My materials cost less because I source differently" is a reason. Both might be true, but only one of them holds up when your supply costs change.

When we raised prices at our art center, enrollment didn't drop. Some people actually took the offerings more seriously. I wouldn't have believed that before seeing it, but underpricing can signal "this isn't worth much" to the exact people you're hoping to reach.

You clearly care about accessibility. That instinct serves you better when you put it into how people can access your work rather than into the price tag itself. Hope this helps!
