Frequently Asked Questions

How is FBA net profit calculated in this estimator?

Net profit per unit = Item Price − Referral Fee − FBA Fee − COGS − Ad Spend − Packaging − Other Costs. Margin is Net Profit ÷ Item Price. Referral Fee uses your category % with Amazon’s typical minimum (often $0.30) when the percentage would be lower.

What referral fee presets are included?

Approximate US rates for planning: Most Categories 15%, Electronics & Computers 8%, Clothing & Accessories 17%, and Books/Music/Media 15%, each with a $0.30 minimum. Switch to Custom to paste the rate from your Seller Central fee preview.

How should I use the break-even price?

Break-even is the selling price where net profit is about $0 after the same fee and cost stack. If your listing price is below break-even, ads or COGS need to drop—or the offer price needs to rise—before the unit is profitable.

How do I maximize FBA contribution margin?

Start with accurate COGS and FBA size-tier fees, then stress-test PPC (ad spend per unit). Lower packaging waste, avoid oversized tiers when possible, and keep ACoS from eating the entire contribution margin. Cross-check detailed fee tiers in the Amazon FBA Profit & Fee Calculator.

Is my pricing data uploaded?

No. Every estimate runs in your browser tab with React state only. Nothing is transmitted—safe for private SKU planning.

Amazon / FBA Revenue Estimator: Net Profit, Margin & Break-Even

Amazon FBA sellers price against referral fees, fulfillment charges, product cost, and often PPC. Ignoring any one of those turns a “healthy” Buy Box price into a loss once ads and prep are included.

This free Amazon / FBA Revenue Estimator models per-unit economics in the browser. Enter item price, pick a referral category (or custom %), set FBA fixed/variable fees, COGS, ads, packaging, and other costs. See revenue, Amazon fees, net profit, margin, a cost-composition bar, and break-even price update live.

Use it beside the Amazon FBA Profit & Fee Calculator for size-tier deep dives, the Shopify Margin Calculator for DTC comparisons, and the Shopify Barcode Generator when preparing inventory labels. Rates are approximate US planning figures—confirm live fees in Seller Central before you buy inventory.
