Product & Cost Inputs
Quick = fast estimate with category defaults | Advanced = precise profit
Storage uses Amazon's official 2026 US monthly fee (standard $0.78 / peak $2.40 per ft³). Placement uses the midpoint of Amazon's official 2026 range. Return-rate defaults are industry estimates from public research — override with your own data.

Fee schedule & editorHow break-even is calculated
Break-even price is the sale price at which net profit reaches zero under your current cost and fee inputs. The calculator re-derives every line item — referral tier, fulfillment band, surcharge, storage and returns — at candidate prices until the crossing point is found, so tier boundaries (like beauty flipping from 8% to 15% at $10) are fully accounted for. The result is rounded to the cent.
Fulfillment fee = official 2026 band rate for the billable weight (greater of actual vs dimensional weight ÷ divisor); odd ounces round up to the next even tier; fuel & logistics surcharge = 3.5% of the fulfillment fee (non-peak).
Dimensional weight = L × W × H ÷ 139 (US inches/lb); billable weight uses dimensional when it exceeds actual weight.
Storage = monthly rate per ft³ (standard $0.78, peak $2.40) × (L×W×H ÷ 1728) × storage days ÷ 30, plus inbound placement fee split by option.
Returns = return rate × (referral + fulfillment + surcharge + return fee + landed cost), amortized per unit.
Break-even price = binary search over candidate prices (precision $0.01) until net profit ≈ 0, re-deriving every tier boundary at each candidate.
