The Black Friday Margin Calculator
Know what you keep before you pick a discount
So here's the thing. Most owners pick a Black Friday discount because the big stores are at 25 or 30% off, and then they find out in December what it cost them. Type in one product, and this shows you what you keep at full price, what you keep with your offer, and the line you shouldn't cross.
- What you keep on one order, with and without your offer
- Up to 3 offers side by side, each marked PASS or MARGIN FLAG
- A Good, Better, Best set priced so it protects your margin
Free. Excel or Google Sheets. About 30 seconds.

The made-up example in the calculator: an $89 kettle that costs $31, $9 shipping, 3% + $0.30 card fee, $30 floor. The 8% is our brand's average discount on Black Friday weekend, November 2025.
Who made this
Hey, I'm Nathan.
I ran a consumer products brand as CEO. It took about 14 years to reach $10 million, then nearly $30 million in about 3 more. So to me, the discount is the last decision, not the first.
Our big weekend ran at about 8% off while the big stores ran 25 to 31%, and our November still grew 63%. That's one brand, not a promise about yours. But it started with knowing our number before we picked our offer, and that's what this calculator does for you.

Questions
Questions owners ask
Is it free?
Yes. No card and nothing to cancel. You tell me where to send it, and it's yours to keep.
What's the most I can discount and still make money?
Honestly, it depends on your numbers, not anyone else's. Put in your price, what it costs you, shipping and the card fee, and the calculator shows the line. On the kettle example it's about 18%. Yours could be 10 or 40.
I don't know my exact costs. Can I still use it?
Yes. Use your best guess, round up on shipping, and you'll still see where the line is. Fix the numbers when you have them.
Does it work for Shopify or WooCommerce?
It does. It's a spreadsheet, so it works with any store. It opens in Excel or Google Sheets, and the example is already filled in so you can see how it works first.
What happens after I sign up?
The calculator and the two bonus tools open on the next page, and we email you the links. If you'd like a hand with the whole November after that, there's a next step on that page for your size of store.
