Pricing paralysis is nearly always a confidence problem wearing a maths costume. You are not trying to find the objectively correct number. You are trying to find a number that a real person will pay today, so you can start learning from actual sales.
Three anchors
Rather than agonising, pick from three anchors and move on:
- The impulse price. Low enough that nobody has to think. Good for a first product and for building an audience that has bought from you once.
- The considered price. Two or three times the impulse price. The buyer weighs it up — so the page has to do real work.
- The outcome price. Priced against what it saves or earns them, not against what it cost you to make. This is where most creators undercharge.
Then change it
Ship at a price, watch the conversion rate, and change it. Ten sales tell you more than a week of deliberation, and a price is one of the easiest things in your business to edit.
