Overview

Estimate net profit, profit margin and break-even for any sale by entering what you charge the buyer (Sale tab) and what it costs you to fulfil it (Cost tab). Marketplace fees, payment fees, shipping and any extra charges are calculated automatically and visualised in the breakdown chart.

Top metrics

• Est. Net Profit — what you keep after all costs and fees. Two percentages are shown next to it:
  • Margin — profit ÷ combined price (what the buyer actually pays). This is the standard gross margin and is comparable across products and marketplaces.
  • Markup — profit ÷ item cost. Useful when comparing buy/sell deals — answers "how much did I make on top of what I paid".
• Break Even — the selling price at which net profit equals zero, holding shipping charges, discount, costs and fees constant. Use it as your minimum price floor. If the value is shown as 0, you are already profitable without raising the price (e.g. shipping charged covers the costs).
• Combined Price — what the buyer actually pays: selling price + shipping charges − discount.

Sale tab — what the buyer pays

• Selling Price — the listing price you charge for the item.
• Shipping Charges — postage charged to the buyer. Pick a saved Shipping Courier from the dropdown to auto-fill the price.
• Discount — switch between a fixed Amount and a Percentage of the selling price using the toggle. Only one mode is active at a time, so the two cannot stack accidentally.

Cost tab — what fulfilment costs you

• Item Cost — add one or more lines with "Add Item". Pick a product from your inventory to auto-fill the unit cost, or type it manually. Set quantity to multiply; the line total and the badge counter update automatically.
• Shipping Cost — what you actually pay the courier (separate from the shipping charged to the buyer). Saved Shipping Couriers can be selected from the dropdown.
• Sale Channel Charges — marketplace fees as a fixed amount and/or a percentage. Use the Marketplace selector to load average rates for eBay, Amazon, Etsy, Walmart, AliExpress, Mercado Libre, Zalando, Allegro, Shopee, Lazada and Facebook. Your own saved channel fees appear under "My fees" at the top of the list. Values are editable after selection.
• Transaction Charges — payment processing fees (fixed amount and/or percentage). Pick a saved payment provider from the dropdown to pre-fill.
• Additional Charges — add as many extra charges as you need (packaging, handling, regulatory fees, etc.) with "Add Charge". Each line accepts a fixed value, a percentage, or both. The badge counter shows how many lines are active.

Marketplace rates shown in the picker are approximate averages for business sellers — adjust them if your account has custom fees.

Saving values for reuse

Whenever you type a value, a small "Save" link appears next to the field. Click it to save the entry as a preset (Shipping Courier, Discount, Channel Fee, Payment Provider or Additional Charge). Saved presets show up in the matching dropdowns on this and the Price Calculator pages so you do not have to re-enter them.

Breakdown chart

The pie chart on the right shows what percentage of the selling price goes to each cost category and how much is left as profit. Hover any segment for the exact amount and percentage. Use it to spot where your margin is being eaten — high marketplace fees, expensive shipping or overpriced items.

Tips

• Set "Selling Price" first, then fill the Cost tab — the metrics and the chart update live as you type.
• Use Break Even as your minimum acceptable price when negotiating discounts or running promotions.
• Save your most used couriers, marketplaces and payment providers as presets so a full calculation only takes a few clicks.
• When comparing two marketplaces, swap the Sale Channel Charges preset and watch the profit move in real time.
