I got an email last week from a seller who’d just run his numbers through our calculator. Subject line: “Is this thing broken?”
He thought the number was too high.
It wasn’t. He’d been undervaluing his business for two years because he didn’t know what buyers actually look at. The calculator just showed him what the market already knew.
Here’s how it works, what it tells you, and what to do once you have your number.
What do I need to use this calculator?
Four things. Your store URL, your email, the year you launched, and your monthly revenue range. No P&L uploads. No tax returns. You don’t even need exact revenue—we ask in ranges, so you can finish the whole thing in about 30 seconds while your coffee’s still hot.
Do I have to pay?
No. The basic valuation is free. We’ll also send you a detailed breakdown of your number—what helped, what hurt, and how to fix it. That’s free too.
Why do you need my store URL?
Spam filter, mostly. It confirms you’re running a real Shopify store. We don’t access your admin or scrape your data.
And my email?
The detailed report goes to your inbox. You get a number on screen, but the full analysis is easier to digest as a document you can keep. No, we don’t add you to a drip campaign. No, we don’t sell your email. You’ll get the report and that’s it.
What does the calculator actually calculate?
It takes your revenue range and your store’s founding year, then cross-references them against what similar stores have actually sold for. From there, it applies an SDE multiple—Seller’s Discretionary Earnings, the standard way buyers price Shopify businesses—to generate your number. (Note: Sellable inventory at cost is always calculated separately and added on top of this number.)
A store making $3K-$20K a month since 2021 gets a different number than one with the same revenue that launched in 2025. The older store has survived more ups and downs. Buyers pay a premium for that track record.
Why do you ask for revenue in ranges instead of exact numbers?
Two reasons. First, it’s faster—you don’t need to pull up your P&L. Second, a range is actually enough for a reliable estimate. The difference between $4,200 and $4,800 a month doesn’t change your valuation in a meaningful way. The difference between $4K and $20K does.
What does the report tell me that the screen doesn’t?
The on-screen number tells you where you stand. The report tells you why. It flags which factors pushed your valuation up, which ones held it back, and what you can do to change them.
If your store is young, the report will tell you that age is limiting your multiple—and when that changes. If your revenue range puts you in a bracket where buyers are paying higher multiples, it’ll flag that too.
What if I don’t like my number?
That’s actually useful. Now you know where you stand. More importantly, the report includes a list of things you can do to move that number—document your finances, diversify your traffic, build your email list, reduce how many hours you work in the business. Come back in three months, run it again, and see what changed.
How long until I get the report?
Usually minutes. Sometimes a couple hours during high volume. Always same day.
Does this work if I’m not on Shopify?
Yes, with a caveat. The methodology—SDE multiples, revenue ranges, age adjustments—applies to Amazon FBA, Etsy, WooCommerce, pretty much any ecommerce business. But we optimized it for Shopify, so that’s where it’s most precise.
Can I use this number to set my listing price?
Absolutely. It’s a market-grounded starting point. Walk into a broker conversation or a marketplace listing knowing your number, and you’re negotiating from strength. For stores above $500K, pair it with a professional appraisal for a precise figure.
How often should I run this?
Once a year minimum. Every quarter if you’re thinking about selling. I’ve watched sellers run it, make operational changes, and come back six months later to a number that’s $30K-$50K higher. Tracking it over time tells you whether the changes you’re making are actually moving the needle.
