What is gross versus net revenue in this Amazon FBA model?

Gross monthly revenue is selling price multiplied by shipped units. Net revenue after fees and returns subtracts modeled referral fees, FBA fulfillment, storage, and conservative return loss, but it does not subtract advertising or product cost. The labels keep those layers separate so you can see where revenue goes.

How do I find the FBA fulfillment fee per unit?

Use the current product dimensions and weight in Seller Central's fee preview or Amazon's Revenue Calculator, select FBA, and enter the applicable pick, pack, and weight-handling amount. Keep it editable because size tier, marketplace, and current fee terms can change. This page does not fetch or claim to reproduce the official rate card automatically.

What storage amount should I enter each month?

Enter the total storage amount you expect for the inventory held in Amazon warehouses during the month, not a per-unit amount. Use current FBA inventory or fee reporting, then adjust for season, dimensions, inventory age, and any aged-inventory charges that apply.

How are returns treated in the revenue forecast?

Return loss is modeled as gross revenue multiplied by the return rate. The conservative result does not assume a referral-fee refund because refunds vary by category and policy, and it does not model every return-processing or disposition cost. Compare the result with recent settlement data when available.

Are ads included in net revenue after fees and returns?

No. Advertising is shown as its own input and is subtracted only from the modeled monthly result after fees and returns. This lets you compare channel revenue before ads with the result after PPC or DSP spend.

Does the monthly profit result include product cost?

No. The modeled monthly result subtracts Amazon fees, return loss, and advertising, but product cost and broader overhead remain outside this calculator. Subtract product cost multiplied by shipped units, then use Amazon Profit Calculator when you need a complete take-home view.

Amazon FBA Revenue Calculator: Monthly Revenue After Fees

Use this Amazon FBA revenue calculator for the monthly channel question: how much revenue remains after modeled referral fees, manual FBA fulfillment, storage, returns, and advertising? Enter shipped units and selling price for gross revenue, then separate Amazon fee buckets, conservative return loss, net revenue after fees and returns, and the modeled result after ads. The FBA fulfillment amount is a manual input from the applicable size tier, not an automatic official rate-card calculation. Product cost and broader overhead stay outside this calculator, so use Amazon Profit for full take-home economics.

Interpretation

How it works

Methodology & formulas

This calculator is transparent by design. Review the steps and formulas so you can trust the estimate and adjust assumptions when your dashboard differs.

Calculation steps

1GrossRevenue = sellingPrice × monthlyUnitsSold.
2TotalReferral = gross × referralPercent.
3TotalFBA = fbaPerUnit × monthlyUnits.
4TotalAmazonFees = referral + fba + storageMonthly.
5ReturnLoss = gross × returnsRate.
6NetRevenueAfterFeesAndReturns = gross - totalAmazonFees - returnLoss.
7MonthlyProfit = netRevenue - advertisingSpend.
8EffectiveFeeRate = totalAmazonFees / gross ×100.

Formulas

Gross = price × units
ReferralTotal = gross × referral%
FBATotal = fbaPerUnit × units
AmazonFees = referralTotal + FBA + storage
ReturnLoss = gross × returnsRate%
NetAfterFeesReturns = gross - AmazonFees - returnLoss
MonthlyProfit = netAfter - adSpend

Important assumptions

Gross monthly revenue = selling price multiplied by shipped units.
Referral fees = gross revenue multiplied by the editable referral percentage for the modeled profile.
FBA fulfillment fees = manual per-unit amount multiplied by shipped units, including units that later return because fulfillment was still performed.
Total Amazon fees = referral fees plus FBA fulfillment plus monthly storage.
Return loss = gross revenue multiplied by the return rate. The model treats returned sales as gross revenue loss and does not assume a fee refund.
Net revenue after fees and returns = gross revenue minus total Amazon fees and modeled return loss. Advertising remains separate.
The modeled monthly result after ads = net revenue after fees and returns minus advertising spend. Product cost and broader overhead are not included.
Fee refunds on returns vary by category and current policy, so this conservative model does not estimate them automatically.
The manual FBA fulfillment input is a planning assumption from the relevant size tier, not an automatic official Amazon rate-card calculation.

Worked example

Worked example: 150 FBA units a month

This channel-revenue example uses a $32.99 price, 150 shipped units, a manual $5.20 FBA fee per unit, 15% referral, $75 storage, $600 ads, and a 4% return rate. Product cost is shown only as a separate follow-on scenario.

Gross $4,948.50. Referral $742.28, FBA $780, and storage $75 produce total Amazon fees of $1,597.28. Return loss is $197.94, leaving net revenue after fees and returns of $3,153.28. The modeled monthly result after $600 ads is $2,553.28, before product cost and broader overhead. If product cost is $8 per unit, the illustrative result after product cost is $1,353.28.
