Where can I find the Amazon revenue calculator?

Amazon provides its own calculator inside Seller Central, but it requires a seller account and can feel complex for beginners. That’s where free tools like the Hustle Framework Amazon FBA Revenue Calculator come in. Our version is fast, simple, and doesn’t require you to log in — making it perfect for anyone researching product opportunities or testing profitability before committing to inventory.

How does the FBA revenue calculator work?

The calculator estimates profit by factoring in:

1. Product cost – what you pay your supplier per unit.

2. Selling price – the price you list on Amazon.

3. Amazon referral fee – usually 8–15% depending on category.

4. Fulfillment fee (FBA fee) – charged per unit to pick, pack, and ship.

5. Storage fees – monthly or long-term, based on space used.

Once you input your data, the calculator subtracts Amazon’s costs and shows:

• Net profit per unit

• Profit margin %

• ROI (Return on Investment)

This allows sellers to see exactly what they’ll make after Amazon takes its cut.

How to use the Amazon FBA revenue calculator

Using the calculator is straightforward:

1. Enter your product cost (what you pay per unit).

2. Enter your selling price (your planned listing price).

3. Add in Amazon fees (referral + FBA).

4. Include storage or shipping costs if known.

5. Review your net profit, margin, and ROI instantly.

This saves hours of manual math and ensures you launch only products that are truly profitable.

If you’re selling in the UK, fees work slightly differently. Sellers must consider:

• VAT (Value Added Tax) on goods sold.

• Different FBA fulfillment and storage rates in pounds.

• Currency exchange if sourcing in USD or EUR.

The calculator can still be used — simply enter costs in GBP and adjust for VAT if applicable. This makes it easy for UK sellers to plan profitability without surprises.

What is the ROI formula for Amazon FBA?

ROI (Return on Investment) shows how much profit you make compared to what you spent on inventory. The formula is:

ROI = \frac{\text{Net Profit}}{\text{Cost of Goods Sold}} \times 100

Example:

• Product cost = $10

• Selling price = $25

• Amazon fees = $8

• Net profit = $7

ROI = (7 ÷ 10) × 100 = 70% ROI

This means for every $1 spent on inventory, you earn $0.70 in profit. ROI is a crucial metric for deciding whether a product is worth scaling.

How much is storage fees at FBA?

Amazon charges sellers for storing products in its warehouses:

• Monthly storage fees: Charged per cubic foot. Standard-size items average $0.87 per cubic foot per month (Jan–Sep) and $2.40 (Oct–Dec).

• Long-term storage fees: Additional charges for inventory stored 365+ days.

• Oversized items: Higher rates due to space requirements.

These costs can quickly add up, which is why many sellers miscalculate profitability if they ignore storage fees.

Additional factors to consider when calculating FBA revenue

Beyond storage and referral fees, sellers should remember:

• Shipping to Amazon warehouses – freight and import duties can cut into profit.

• Returns and refunds – Amazon’s return policy can reduce net earnings.

• Labeling and prep fees – extra charges if Amazon prepares products for you.

• Advertising spend (PPC) – many sellers forget to include this in ROI.

• Currency fluctuations – important for international sellers sourcing abroad.

Common mistakes sellers make when calculating FBA profit

• Only looking at revenue, not net profit.

• Forgetting seasonal storage cost increases.

• Underestimating Amazon’s referral and fulfillment fees.

• Ignoring returns and advertising spend.

• Overcommitting to a product without testing profitability first.

Why calculating FBA revenue matters

Amazon is one of the most competitive marketplaces in the world. Sellers who understand their costs thrive — those who don’t, struggle to scale. Profit isn’t just about selling price; it’s about margins, ROI, and sustainable business growth. A small miscalculation can mean thousands lost on a single shipment.

That’s why tools like the Amazon FBA Revenue Calculator are essential — they help you see the full picture before you invest in inventory.
