About the Amazon FBA Profit Calculator
An Amazon FBA Profit Calculator Australia helps sellers determine their true profitability on Amazon after accounting for all fees, shipping, and GST. With Amazon Australia's marketplace growing rapidly in 2025-26 and more local businesses launching FBA products, understanding net profit per unit is essential before sending inventory to Amazon's fulfilment centres. Australian sellers face unique costs including GST on sales over $75,000, higher inbound shipping rates, and Amazon Australia's fee structure which differs from the US and UK. This calculator incorporates Amazon Australia's specific referral fees, fulfilment fees, monthly storage charges, and the Australian GST regime to give you an accurate picture of your bottom line. Whether you sell in Sydney, Melbourne, or Brisbane, knowing your true profit per unit determines whether a product is worth scaling.
What is the Amazon FBA Profit Calculator?
The Amazon FBA Profit Calculator is a financial tool that computes the net profit per unit sold through Amazon's Fulfilment by Amazon service. It accounts for the item selling price, Amazon referral fee (typically 8-15% depending on category), FBA fulfilment fee (pick, pack, and ship), monthly storage fee, your product cost, inbound shipping to Amazon warehouses, and any advertising costs. For Australian sellers, the calculator also handles GST treatment. Products sold on Amazon Australia to Australian customers include 10% GST in the selling price, which must be remitted to the ATO. The tool calculates your profit both with and without GST so you can understand your cash position. It also displays key metrics like profit margin percentage, break-even ROAS for PPC advertising, and net profit after all fees. This is particularly critical for Australian FBA sellers competing against low-cost imported goods, where margins are often thin and accurate cost tracking separates profitable products from loss leaders.

Worked Australian Example
Practical Example
Brisbane-based seller EcoHome Australia wants to list a bamboo kitchen brush set on Amazon FBA for $29.99. Their product cost is $8.50 including import from Vietnam. The Home & Kitchen category has a 15% referral fee. FBA fulfilment fee for the standard-size item is $5.45. Monthly storage fee is $0.45 per unit. Inbound shipping to Amazon's Sydney fulfilment centre is $1.20 per unit. They plan to spend $2.00 per unit on PPC ads. Using the Amazon FBA Profit Calculator, they enter these figures. The tool computes gross revenue of $29.99, referral fee of $4.50, fulfilment fee of $5.45, storage fee of $0.45, inbound shipping of $1.20, product cost of $8.50, and PPC cost of $2.00. Total costs are $22.10. Net profit per unit is $7.89, a 26.3% margin. However, the calculator also notes that GST of $2.73 must be remitted on each sale. EcoHome Australia decides the margin is healthy enough to proceed and launches with 500 units. The calculator saved them from missing the $2.00 PPC cost, which alone would have reduced their perceived margin by 25%.
