Know Your Numbers Before You Invest
Selling on Amazon through FBA means juggling referral fees, fulfillment costs, storage charges, ad spend, and returns, all before a single dollar hits your account.
Brandock’s free Amazon FBA & Revenue Calculator puts all of those variables in one place, so you see real net profit before you commit to a product or a purchase order.
What does the Brandock Amazon FBA & Revenue Calculator include?
The calculator runs across two modes.
The FBA Profit Calculator takes your selling price, cost of goods, inbound shipping, product category, size tier, monthly storage cost, and PPC ad spend per unit, then delivers a full cost breakdown showing exactly what you keep after Amazon takes its cut.
The Revenue & Growth Calculator goes further: input your monthly unit volume, return rate, and expected month-over-month growth, and it projects your revenue and net profit across a six-month window.
Together, they function as a complete Amazon FBA profit estimation tool, covering both snapshot profitability and forward-looking revenue forecasting.
Who is this calculator designed for?
It works for Amazon sellers at any stage. Beginners can use it to evaluate whether a product is worth sourcing before placing their first order.
Established sellers can use it to model margin impact when costs change, a supplier’s price increases, new PPC budgets are set, or a shift to a larger size tier occurs.
It’s built to be an Amazon FBA calculator for small businesses and individual sellers, but the revenue projection functionality also supports more advanced scenario planning.
Can I use this calculator for international Amazon marketplaces?
The fee data in the tool reflects U.S. Amazon rates. If you sell on Amazon UK, EU, CA, or other international marketplaces, referral fees and fulfillment fees differ by marketplace.
You can still use the calculator by manually entering the correct fee percentages and fulfillment costs for your marketplace in the relevant fields; both tabs accept custom inputs.
What metrics does the FBA profit calculator provide?
The profit tab outputs a full cost breakdown: referral fee amount, fulfillment fee, storage cost, PPC cost, COGS, and other per-unit costs are all itemized before arriving at your net profit per unit.
The revenue tab outputs monthly revenue, monthly net profit, and a six-month cumulative view with a chart showing both revenue and net profit across the projection period.
Frequently Asked Questions (FAQs)
It shows you net profit before you commit. Instead of estimating margin, you see exactly what’s left after referral fees, fulfillment costs, storage, and ad spend are deducted. That makes it useful for product validation, repricing decisions, and supplier negotiations — any situation where knowing your real numbers matters.
Yes. The profit tab accepts your COGS, inbound shipping, and a catch-all field for other per-unit costs like prep and packaging. On the Amazon side, it factors in your referral fee by product category, FBA fulfillment fee by size tier, monthly storage cost, and PPC spend per unit sold, giving you a complete expense breakdown in one place.
The revenue tab multiplies your selling price by monthly units sold, adjusts for your return rate, then deducts the referral fee, FBA fulfillment fee, product cost, and monthly PPC budget. Your growth rate is compounded forward to produce a six-month net profit projection — not just gross revenue.
Fee data is updated for 2026 and covers current referral fee percentages and fulfillment rates across all major size tiers. Accuracy beyond that depends on your inputs; sellers using real COGS, actual shipping costs, and current PPC figures will get projections that closely reflect live performance.
It assumes a fixed selling price with no promotional discounts or buy box fluctuations. The growth projector applies a flat month-over-month rate rather than accounting for seasonality. Long-term storage fees, removal fees, and unplanned prep charges aren’t included — add those to the “other costs per unit” field if they apply to your business.
It produces a six-month forward projection based on your current volume, growth rate, and cost structure, not a guaranteed forecast. It’s most useful as a planning tool when updated regularly with real performance data.
Yes. Brandock’s Amazon FBA & Revenue Calculator is completely free, with no account required and no data submitted. All calculations run in your browser. There are no limits on how many times you can run a scenario.
FBA adds fulfillment fees and storage costs that don’t apply to FBM (Fulfilled by Merchant) or third-party logistics. In exchange, FBA listings typically qualify for Prime, which affects conversion rate and the volume of units sold.
