The worked example below shows the formula and the independently rendered default-input results.

Complete worked example

Calculate marketplace break-even from sample inputs

These are the same starting values loaded into the interactive calculator above. The displayed results below come from the same calculation engine as the live tool.

Step 1 — Record the inputs

Product cost$18
Fulfillment and shipping cost$6
Fixed transaction and order costs$1
Advertising cost per order$4
Percentage seller fee12%

Step 2 — Identify the formula

FORMULABreak-even price = (Product + Fulfillment + Fixed fees + Ads) ÷ (1 − Seller fee rate)

Step 3 — Substitute the values

For this exact worked case, use Product cost = $18; Fulfillment and shipping cost = $6; Fixed transaction and order costs = $1; Advertising cost per order = $4; Percentage seller fee = 12%. Replace named formula variables with their input values as shown below. Keep the units consistent; a percent is divided by 100 wherever the model requires a decimal rate.

NUMERIC SUBSTITUTIONBreak-even price = ($18 + $6 + $1 fees + $4) ÷ (1 − Seller 12% rate)

Step 4 — Read the calculated answer

Minimum break-even selling price$32.96
Fixed variable costs per order$29.00
Seller fee at displayed price$3.96

Rounding follows the calculator display: whole units may be rounded up when an indivisible unit is required, while other values typically show up to two decimal places. The result is conditional on the entered assumptions, not a market quotation.

Decision interpretation

How to interpret this marketplace break-even result

This model does not include taxes or returns and does not assume a platform-specific fee schedule. Set the actual seller fee rate for your case.

Apply this result to a real order, product listing, or marketplace campaign. Reconcile the modeled amount with product cost, fulfillment, returns, promotions, and payment charges.

Scenario comparison

Compare a regular-price order with a discounted order, including any extra shipping or promotional subsidy.

Assumptions and limitations

Seller fees and shipping terms differ by platform, category, region and date. Any percentage entered is your assumption, not a live platform quote.

  • Product cost: Enter a finite monetary value of at least 0. Use a consistent definition across comparison cases.
  • Fulfillment and shipping cost: Enter a finite monetary value of at least 0. Use a consistent definition across comparison cases.
  • Fixed transaction and order costs: Enter a finite monetary value of at least 0. Use a consistent definition across comparison cases.
  • Advertising cost per order: Enter a finite monetary value of at least 0. Use a consistent definition across comparison cases.
  • Percentage seller fee: Enter a finite percentage value of at least 0 and no more than 100. Use a consistent definition across comparison cases.

Frequently asked questions

Why could my real result be different?

Seller fees and shipping terms differ by platform, category, region and date. Any percentage entered is your assumption, not a live platform quote.

How should I compare two results?

Compare a regular-price order with a discounted order, including any extra shipping or promotional subsidy. Record the assumption that changed so a higher or lower answer is interpretable.
