Frequently Asked Questions

FBA vs FBM Costs?

FBA means Amazon handles storage, packing, shipping, and customer service. FBM means you manage these. FBA has per-unit fees but can boost sales. FBM requires you to calculate your own shipping/handling costs.

Referral Fees?

A percentage of the VAT-inclusive selling price, varying by category and sometimes price. This calculator applies these rules automatically. A minimum fee (often £0.25) may also apply.

Digital Services Tax (DST)?

For Irish sellers on Amazon UK, a DST of 2% is applied to Referral Fees and FBA Fees. This calculator automatically includes it if GBP is selected as the marketplace currency.

Storage Fee Calculation?

Estimates first month’s storage using ‘Initial Shipment’, ‘Monthly Sales’, and Amazon’s ‘Storage Fee Rate’. The per-unit cost shown is this total averaged over sales. The 12-month forecast uses this per-unit storage cost applied to forecasted sales.

VAT Calculation?

“Selling Price” should be VAT-inclusive. VAT is deducted based on the selected rate to find net selling price. Referral fees are charged on the VAT-inclusive price.

FBA Fee Accuracy?

The FBA Fee input is manual. For accuracy, always use Amazon’s official FBA Revenue Calculator. This tool uses the fee you provide.

Break-Even Point?

The number of units or revenue needed per month to cover all your fixed and variable costs (including estimated agency fees if selected). Essential for understanding minimum sales targets.

ROAS & TACoS?

Return On Ad Spend (ROAS) and Total Advertising Cost of Sales (TACoS) help measure the efficiency of your marketing spend. TACoS is marketing spend as a percentage of total sales revenue.

Impact of Returns?

Customer returns can significantly impact profit. Input your estimated return rate and average cost per return (including lost product value and processing) to see a more realistic net profit.

Inventory Metrics?

Inventory Turn shows how many times your inventory sells through in a period. Days of Inventory indicates how long your current stock will last. Important for cash flow and avoiding long-term storage fees.

Agency Fees?

You can select an agency service tier to see its impact on your profitability. Fees are based on your number of products and monthly revenue, according to a tiered structure.

CM2 vs CM3?

CM2 (Contribution Margin 2) shows your margin before advertising and agency fees. CM3 (Net Margin) is your final margin after all costs, including advertising and any agency fees.

12-Month Forecast Input?

You can forecast sales using a monthly growth percentage or by manually inputting sales units for each of the 12 months. Marketing costs will scale with sales if using the growth factor, or can be input manually if manual sales are selected.

CSV Export & Formulas?

The forecast can be exported as a CSV. While direct Excel formulas aren’t embedded, the data is structured for easy formula application in spreadsheet software like Excel or Google Sheets.
