The Spreadsheet That Stops You From Falling In Love With A Money-Losing Product

Most people pick a product, get emotionally attached to it, contact 17 suppliers, design custom packaging, name their future yacht (it's "Lava You"... thank you very much)... and THEN discover the math never worked.

That's a painful (and expensive) way to learn a lesson.

This free Google spreadsheet flips the whole process on its head.

It's called the Minimum Viable Margin Math Calculator, and it does one brutally important thing: it tells you the maximum you can afford to pay for a product BEFORE you waste a single minute chasing it down on Alibaba.

Plug in your target selling price and it automatically calculates every cost that's going to eat your margin alive - Amazon placement fees, fulfillment fees, shipping into Amazon, testing, compliance, duties... all of it.

Then it uses my 40% contribution margin rule to back you into your maximum allowable product cost.

If the product can be made for that number? You're in business. If it can't? You just saved yourself months of heartbreak and thousands of dollars.

I built this as part of Step 3 of my One Product Method, and I'm handing it to you completely free.

Drop your name and email below and I'll send it straight to your inbox.

Your future profitable product will thank you.
