FBA landed-cost tool
Amazon FBA Total Landed Cost Calculator
Assumes Amazon US FBA. Import-duty inputs are US entry fees for goods imported into the United States, not US duties on exports.
Total landed cost for Amazon FBA is the complete cost of getting a product from supplier to sold unit. It includes COGS, inbound shipping, import duty, insurance, FBA prep fees, inbound placement fees, fulfillment fees, referral fees, storage fees, and returns processing. This calculator combines every cost in one place, calculates net profit and net margin per unit, shows your break-even selling price, and returns a GO or NO-GO verdict against your minimum acceptable margin using the full 2026 Amazon fee schedule. All calculators support both imperial (inches and pounds) and metric (centimeters and kilograms) units via the toggle at the top of each form.
Most FBA sellers calculate margin wrong. They subtract the referral fee and fulfillment fee from the selling price and call it profit. But the real cost of selling on Amazon starts before the product reaches the warehouse. COGS, inbound shipping, import duty, prep fees, inbound placement, storage, and returns all come before net profit. This calculator puts every cost in one place and tells you before you order inventory whether the numbers work.
Your margin of 38.9% exceeds your 25% threshold. This product passes the FBA math test.

Frequently Asked Questions
Essential answers on calculating true Amazon FBA landed cost, placement fees, margin benchmarks, and TACoS limits.
What is total landed cost for Amazon FBA?
Total landed cost for Amazon FBA is the complete cost of getting a product from your supplier to a sold unit on Amazon. It includes cost of goods sold (COGS), inbound shipping from supplier to Amazon, import duty, cargo insurance, FBA prep fees, inbound placement fees, Amazon fulfillment fees, referral fees, monthly storage fees, and returns processing allowance. Most sellers underestimate their true landed cost by excluding one or more of these line items. The difference between estimated and true landed cost is where FBA margin surprises come from.
Why does Amazon charge an inbound placement fee?
Amazon introduced inbound placement fees in March 2024 as part of the transition to its distributed inventory placement network. When creating a shipment plan sellers choose between minimal placement (sending to fewer fulfillment centers at a higher per-unit fee averaging $0.27) and optimized placement (sending to multiple fulfillment centers Amazon selects at a lower per-unit fee averaging $0.14). The fee reflects Amazon's cost of distributing inventory across its fulfillment network. Amazon-optimized placement sends inventory to 4 to 5 fulfillment centers and charges zero placement fee but requires shipping to multiple destinations which increases inbound freight cost.
How do I calculate my FBA margin correctly?
FBA margin is calculated as net profit divided by selling price expressed as a percentage. Net profit equals selling price minus total landed cost minus total Amazon fees. Total landed cost includes COGS, inbound shipping, import duty, insurance, and prep costs. Total Amazon fees include the referral fee, fulfillment fee, fuel surcharge, placement fee, storage allocation, and any applicable low inventory or returns fees. Most sellers calculate margin incorrectly by subtracting only the referral fee and fulfillment fee from the selling price. The correct calculation requires all cost line items from supplier to sold unit.
What is the Maximum Affordable TACoS for an FBA product?
Maximum Affordable TACoS (Total Advertising Cost of Sale) is the highest percentage of revenue you can spend on Amazon PPC before your product becomes unprofitable at your target margin. It equals your net margin before advertising expressed as a percentage of selling price. If your product generates 35 percent net margin before ad spend your maximum affordable TACoS is 35 percent. Spending above this level makes the product unprofitable at the unit level. The Total Landed Cost Calculator shows your maximum affordable TACoS automatically based on your specific cost inputs and selling price.
