What This Tool Does
The Amazon FBA Calculator estimates referral fees and FBA fulfillment charges for items fulfilled by Amazon. It allows e-commerce sellers to test retail pricing scenarios and avoid unexpected margin collapse.
How to Use It
- Input your product listing price on Amazon.
- Enter your manufacturing or inventory unit cost.
- Check the standard 15% referral fee and estimated FBA fulfillment fee.
- Review your net margin after Amazon fulfillment and referral deductions.
Worked Example: $29.99 Standard Size Kitchen Accessory
You list a standard-size kitchen gadget for $29.99 via FBA. Your landed manufacturing and freight cost per unit is $7.50.
| Referral Fee (15%) | $4.50 |
| FBA Fulfillment Fee | $3.86 |
| Landed Unit Cost | $7.50 |
| Total Amazon Cut | $8.36 |
From a $29.99 customer sale, your net profit is $14.13, delivering an attractive 47.1% net profit margin.
Common Mistakes to Avoid
- Underestimating FBA size tiers where a fraction of an inch pushes an item into large bulky tier rates.
- Forgetting monthly inventory storage fees (especially peak Q4 rates from October to December).
- Overlooking Amazon returns processing fees and customer return concessions.
- Confusing the Individual Seller $0.99 per-item fee with the Professional $39.99/month subscription.
- Failing to factor in inbound shipping costs to Amazon fulfillment centers.
