Definition
What is Profit Calculator?
CrossKit Profit Calculator is a margin tool that subtracts product cost, marketplace fees, shipping, ads and currency from a selling price. It is for Amazon, Shopify and TikTok Shop unit economics, not a full accounting close. You see profit and margin as you type.
What it is not
What Profit Calculator is not
This page is a browser tool. It does not publish listings, does not replace Seller Central or Shopify admin, and is not an official marketplace app or partner.
How it works
How Profit Calculator works
Fill price, cost and fee lines on the page. Math runs in the browser so you can switch currencies and compare scenarios without a workbook. Copy the resulting margin into your launch sheet. Recalculate when ads or referral fees change.
Use cases
When to use Profit Calculator
Shopify DTC versus TikTok Shop take rate
Hold COGS still and swap the fee stack so a viral SKU does not ship at a loss on Shop while the site stays healthy.
Bundle price that still beats two singles
Add both costs and one shipping event, then test a bundle list price before you create the parent SKU.
Step-by-step
How to use Profit Calculator
-
1
Enter the shelf price in the listing currency
Use the price shoppers see, not a USD habit if the storefront is EUR. Convert first if needed.
-
2
Add COGS, inbound and packaging as separate lines
Hiding inbound inside COGS makes later fee changes impossible to see. Keep labels the same as your finance sheet.
-
3
Apply referral, fulfillment and ad cost
Use last month’s actual ACOS or TACOS if you have it, not a hopeful 0%. Storage is not optional on FBA.
-
4
Read net profit and decide a floor
If margin after ads is thin, raise price, cut the ad bid or skip the SKU. Save the scenario next to the ASIN.
Walkthrough
A real use case for Profit Calculator
- 1
Enter the real selling price including the discount you plan to run.
- 2
Add every cost: product, shipping, platform fee, ad spend, storage, returns.
- 3
Only scale ad spend on SKUs whose margin survives the worst-case return rate.
Comparison
CrossKit vs doing it manually
A Seller Central fee preview plus a spreadsheet works until someone forgets ads or FX. Generic calculators often omit Shop take rates. CrossKit keeps price, cost, fees and currency on one browser form so a launch decision uses the same stack every time.

How CrossKit handles your data
Price and cost figures are calculated in the browser. CrossKit does not sell your margin model or treat it as financial advice storage.
