Never list below your break-even price. This calculator accounts for item cost, shipping, packaging, fees and desired profit.
Formula: Break-even = Total Costs / (1 - FVF Rate). For $30 total costs at 13.25% FVF: minimum price = $34.58.
Add up all costs (item, shipping, packaging) and divide by (1 - fee rate). This gives the minimum sale price to cover all expenses.
