Project Your Amazon Seller Revenue

This calculator estimates your monthly and annual revenue and net profit from a target average selling price and sales volume. It complements the per-unit Amazon FBA Calculator with a higher-level view focused on cash flow and ROI rather than fee detail.

  • Revenue × volume: monthly revenue is simply average price × monthly units sold.
  • Fees scale linearly: each unit incurs Amazon's referral, FBA fulfillment, storage and return-cost overhead — total fees scale with volume.
  • ROI here: monthly net profit ÷ monthly cash invested (product costs + ad spend + fixed costs). It tells you what % of your monthly outlay comes back as profit.
  • Annual numbers are simple ×12 projections — useful for planning, conservative because they assume steady-state volume.

What is Amazon seller revenue?

Amazon seller revenue is the gross dollar amount you collect from sales across your listings, before any costs are deducted. It's the top-line number that defines the scale of an Amazon business — and the number Amazon reports in your Seller Central dashboard. But by itself, revenue tells you very little: a $50,000-revenue month can produce anywhere from a $20,000 profit to a $5,000 loss depending on fees, product cost, ad spend, and return rate.

To know whether a revenue figure is good, you have to project it forward into monthly net profit and annual revenue run-rate, factoring in everything Amazon takes (referral, FBA, storage, returns) plus your variable costs (product, inbound shipping) and any baseline ads. This is the level above the per-unit FBA calculator: total business throughput, not single-order math.

How to project Amazon revenue and profit

Monthly revenue is the simplest part — units × price. The hard work is computing the net that flows through to profit. The full chain:

Revenue: Revenue = Avg price × Monthly units sold

Per-unit Amazon cost: Per-unit cost = Price × Referral% + FBA fee + Storage + Return reserve

Monthly net profit: Net = Revenue − Total Amazon fees − (Product cost × units) − Ad spend − Fixed costs

Annual run-rate: Annual = Monthly × 12, assuming steady-state volume. Real Amazon businesses spike 30–80% in Q4, so annual projections from a non-Q4 month underestimate; projections from Q4 overestimate.

Worked example. A US private-label brand sells 300 units/month at $24.99 average price. Product cost $7.50/unit, ad spend $1,200/month, $200/month fixed costs (software, samples). Per-unit Amazon fees on $24.99: 15% referral ($3.75) + $4.75 FBA + $0.30 storage = $8.80. Monthly: revenue $7,497, Amazon fees $2,640, product $2,250, ads $1,200, fixed $200. Net profit = $1,207/month (16.1% net margin). Annual run-rate: $14,484 net on $89,964 revenue.

A 10% volume increase (330 units instead of 300) lifts monthly profit to ~$1,567 — most fees and costs scale with units, but $200 in fixed costs is spread across more orders. Volume leverage is real but limited unless ad spend stays flat as units grow.

How to use this calculator

Pick your marketplace at the top — auto-fills referral and FBA fee defaults for US, UK, DE, CA, JP, AU. Enter your average sale price (across all SKUs if you have multiple — weight by volume if they differ significantly), monthly units sold, product cost per unit (landed including inbound shipping), monthly ad spend, and any fixed costs that don't scale with volume.

The calculator returns monthly revenue, annual revenue, monthly net profit, annual net profit projection, and profit margin. Use it for runway planning (how much can I draw from the business?), investor or accountant conversations (clean annual P&L preview), or to test "what if I lift price by $2" or "what if I scale ads to $2,000" before committing budget. The advanced section lets you customize the referral and FBA fee for category exemptions.

Real-world examples

Example 1 — Single SKU, steady seller. 200 units/month at $19.99, $6 product cost, $600 ads, $150 fixed. Revenue $3,998. Per-unit fees (15% referral $3, $4.75 FBA, $0.30 storage = $8.05). Total Amazon fees $1,610. Product cost $1,200. Net = $3,998 − $1,610 − $1,200 − $600 − $150 = $438/month, 11% net margin. Tight but profitable — this is roughly the median small-FBA-seller experience. Annual run-rate: $5,256.

Example 2 — Higher-ticket private label. 150 units/month at $44.99, $13 product cost, $1,500 ads (higher-CPC niche), $400 fixed (PPC software, design assets). Revenue $6,749. Per-unit fees: 15% referral $6.75, $5.45 FBA, $0.50 storage = $12.70. Total fees $1,905. Product $1,950. Net = $994/month, 14.7% margin. The higher AOV makes ad spend more efficient relative to revenue. Annual: $11,928.

Example 3 — High-volume kitchen brand. 800 units/month at $29.99, $8 product, $3,500 ads, $700 fixed (VA, design tools, samples). Revenue $23,992. Per-unit fees: $4.50 referral + $4.75 FBA + $0.30 storage = $9.55. Total fees $7,640. Product cost $6,400. Net = $23,992 − $7,640 − $6,400 − $3,500 − $700 = $5,752/month, 24% margin. Annual run-rate $69,024. The volume produces operating leverage on fixed costs and lets ad spend stay below 15% of revenue. This is the FBA scale that allows reinvestment in new SKUs — see the Amazon Seller Calculator for the full opex view.

Common mistakes and benchmarks

The most common projection error is using a peak month to project annual. Q4 (October–December) for Amazon FBA typically does 30–80% above the rest-of-year run-rate. Projecting January revenue × 12 understates the year; projecting November × 12 overstates it dramatically. Use a non-Q4 average month, then add a Q4 lift estimate separately.

Second is treating "ad spend" as the only marketing cost. Coupons, Vine reviews, lightning deals all have effective costs. A $20 product on lightning deal at $15 with 200 daily units doesn't add $1,000/day in revenue — it costs roughly $1,000/day in foregone margin. The calculator's ad-spend field should include all promo-related cost, not just PPC.

Healthy benchmarks. Net margin 12–25% is normal for established FBA private label. Above 25% is exceptional and probably indicates either a high-ticket niche, very low ad spend, or unsustainable supplier pricing. Below 10% net margin is fragile — a 1-month ad-spend overshoot or a Q4 storage surcharge can flip it negative. Aim for ad spend under 25% of revenue, fixed costs under 5%. Compare against the per-unit picture using the FBA Calculator.

Frequently Asked Questions

Multiply average sale price by monthly units sold. For 200 units at $19.99 average: revenue = $3,998/month. To get net profit, subtract Amazon fees (typically 28–35% of revenue for standard-size goods), product cost, ad spend, and fixed costs. Revenue alone is misleading — two sellers with identical revenue can have wildly different profit depending on ad efficiency and product cost. Always project profit, not just top-line revenue.

Monthly revenue equals average price multiplied by units sold: Revenue = Price × Units. Annual revenue is monthly × 12 if you assume steady state — but most Amazon businesses see 30–80% Q4 lift, so annualizing a non-Q4 month understates by 10–20%. To project profit: Net = Revenue − Amazon fees − Product cost − Ad spend − Fixed costs. The calculator chains these automatically once you enter average price, volume, and cost inputs.

Net margin of 12–25% is normal for established FBA private label. Below 10% is fragile — small ad-spend overshoots or Q4 storage surcharges can erase it. Above 25% is exceptional and usually indicates either a high-ticket product, exceptionally efficient ads, or unsustainable supplier pricing. Most successful FBA sellers reinvest profit back into inventory and new SKUs to compound, rather than maximizing margin on existing products at the cost of growth.

Net profit. Revenue is a vanity metric in FBA because Amazon fees alone consume 28–40% of it before any other cost. Two sellers with $100k/month revenue can have profits ranging from $25k (good private label) to negative (over-spending on ads to maintain rank). For business decisions — whether to launch a new SKU, hire a VA, or raise prices — net profit and free cash flow are the only numbers that matter. Profit margin gives you the per-dollar efficiency view.

Only with adjustment. A first-month projection × 12 is wildly optimistic because most new listings take 60–120 days to reach steady-state velocity. Use month 4–6 average × 12 as a baseline, then add 30% for Q4 if your category is gift-oriented. Avoid projecting from a single peak month: November × 12 overstates by 20–40%. Plan inventory and cash flow against the conservative annualized number, not the best-case scenario.

Three usual reasons. First, returns: refunded orders cost you product + FBA + inbound but return zero revenue. A 7% return rate typically reduces net margin by 2–4 percentage points. Second, PPC overspending: Amazon Ads can scale beyond reported numbers if you set high default bids. Third, hidden Q4 storage surcharges and aged inventory fees if you misjudge stock levels. Reconcile actual Seller Central payouts monthly against the calculator's projection — any persistent gap reveals a missing cost input.

Use the FBA Calculator for single-unit decisions: should I source this product, raise this listing's price, change pack size. Use the Revenue Calculator for business-level decisions: monthly run-rate, hiring a VA, drawing from the business as salary, projecting annual P&L for accountants or investors. Per-unit math optimizes individual SKUs; revenue math optimizes the business as a whole. Most established sellers run both calculators side by side, using the per-unit view for sourcing decisions and the revenue view for monthly planning conversations.

Seasonal variance (Q4 lift of 30–80% common in giftable categories), income tax (paid on profit), inventory carrying cost (capital tied up in stock you haven't sold), launch costs for new SKUs, and the time value of money. It also doesn't model Amazon's payout schedule (you receive payouts every 14 days net of reserves) or the impact of suspension/account-health events.
