Break-even price is the sale price at which your profit is exactly $0, given the referral fee % and fixed per-unit costs entered above — it assumes the referral fee scales with price and every other cost stays fixed. Use your own actual cost figures for an accurate result; check current Amazon referral-fee rates at Seller Central.
