A set of tools for turning a candidate listing's price into an actual profit estimate before ordering inventory, rather than guessing at manufacturing/shipping costs or fees.
**Helium 10 X-Ray's Profitability Calculator** — opened from a listing page, auto-pulls the product's dimensions and weight to calculate FBA, referral, and storage fees; enter estimated manufacturing and shipping cost to get per-unit profit.
Alibaba cost sourcing — search Alibaba for the same or a comparable product to replace guessed manufacturing/shipping costs with real numbers: note the per-piece price and the total shipping cost for a sample order quantity, divide shipping by quantity for a per-piece shipping cost, then feed both into the profitability calculator.
Free alternatives — freeamazontools.com offers a free calculator that, like Helium 10's, allows customizing product size/weight and factoring in estimated PPC cost. A more basic free FBA calculator (found by searching 'FBA calculator') estimates fees only, without size/weight customization — useful as a fallback when that level of detail isn't needed.
Feeds the price/demand numbers already screened by Safe Niche Threshold Checklist and Manual Top-Listing Demand Scan (X-Ray Distrust) into an actual margin figure.
A summary/estimated cost figure can hide a niche's true profitability. In one worked example, an item sourced at $15.50/unit plus roughly $13/unit shipping (~$28.50 landed cost) from a real Alibaba quote, sold at a $50-$90 retail price, revealed about $24 in per-unit profit — a margin that would not have been visible without replacing a guessed cost with an actual supplier quote. Always price shipping and unit cost from a real quote before judging a niche's margin.
Amazon's Revenue Calculator can be filled in two ways: search the Amazon catalog for a similar existing product (fast, but risks mismatched dimensions/fees) or manually enter your own product's packaging dimensions and weight straight from the Alibaba listing (slower, more accurate). Convert Alibaba's centimeter dimensions to inches before entering them, since it simplifies every downstream step.
For FBA, set the shipping charge input to $0 since Amazon's fulfillment fee — not a separate shipping fee — covers customer delivery. The Amazon referral fee (roughly 15% of item price in many categories) is identical whether you sell FBA or FBM; the fulfillment cost is what actually differs — a flat FBA fee versus self-estimated FBM packaging and outbound shipping (see FBA vs. FBM (Fulfillment Model Split) for the FBM-side cost tools).
Storage fees are seasonal — Q4 is the most expensive period, cheaper again around January–February — so plugging in Q4 storage rates gives a conservative, worst-case estimate rather than an optimistic average. The calculator's average-inventory and estimated-monthly-units inputs can both be left at a 1:1 ratio to get a clean per-unit profit figure; scaling both proportionally doesn't change the per-unit result.
Critically, the unit price listed on an Alibaba listing is not a real cost of goods — it's a starting point. A real quote requires contacting the supplier directly for manufacturing plus shipping-into-country costs (see Supplier-Quote Comparison Spreadsheet). Whatever real landed cost comes back gets checked against price and target margin using the Rule of Thirds (33% Net Margin) Amazon Profitability Heuristic.
