Many makers add a markup to their cost. The trouble is that marketplace fees and your profit are shares of the selling price, not of the cost. A markup on cost leaves you with less than you planned.
The formula
Price = cost ÷ (1 − fees % − profit %)
Cost means everything one item takes: materials, packaging and your making time at a fair hourly rate.
A worked example (made-up numbers)
Cost 20. Marketplace and payment fees 10%. You want 20% profit.
Check a sale before you run it
A 20% discount on 28.57 makes the price 22.86. Fees fall to 2.29, and your profit falls to 0.57. To earn the same money as at full price, that sale needs about ten times as many orders.
A small free gift, a bundle or free shipping often costs you less than a big discount. Work it out first.
