Etsy Ads break-even calculatorIs 25% off worth it on a $30 Etsy item?
At 25% off, the $30.00 item sells for $22.50 (shipping $5.00 stays the same). Etsy's fees fall from $3.78 to $3.07: the percentage part falls with the price; the fixed part stays, so each order keeps $8.43 instead of $15.22. To keep the same profit you need about 81% more orders (1.81 times as many: about 181 for every 100 now). Send ordersPerMonth for the orders needed a month.
Sale calculatorWhat price gives a 30% margin when materials cost $8 and the label $7?
At an item price of $27.20 (an order of $27.20 with $0.00 shipping), each order pays Etsy's fees of $3.04, $0.00 of Offsite Ads on average and $16.00 of costs, and keeps $8.16, so it reaches the 30% target (Etsy rounds each fee, so it can be a cent off). At an item price below $18.18, an order loses money. Figures are at your numbers; a higher price can lose orders.
