Why These Tools Exist

Your Gut Feeling Is Expensive.
These Numbers Are Free.

You're making financial decisions all week long. How much to spend on Meta ads. Whether to raise your price by RM5. When to reorder inventory before Chinese New Year cleans you out. Most DTC founders make these calls on gut feel or half-built spreadsheets. That's how profitable products quietly become money losers. These free ecommerce calculators give you real numbers in seconds — so you can stop guessing and start deciding with confidence.

Here's what we've noticed after working with dozens of ecommerce brands: the ones who know their unit economics always outperform the ones who don't. Founders who can tell you their contribution margin per SKU, their actual customer acquisition cost by channel, and their customer lifetime value make consistently better bets on inventory, pricing, and ad spend. Not because they're smarter — because they're working with real data instead of assumptions.

Maybe you're a Shopify store owner wondering if your Facebook ads are actually profitable (or just generating revenue you'll never keep). Maybe you're an ecommerce marketer trying to justify your SEO investment to a founder who wants to see the numbers. Or maybe you're evaluating whether the total cost of running Shopify still makes sense at your scale. Whatever your question, there's a calculator here that answers it — with real formulas and DTC industry benchmarks so you can see exactly where you stand.

The advertising tools show you your return on ad spend and the minimum ROAS you need to stay in the black. The pricing tools help you set prices that actually work after COGS, payment processing, shipping, and platform fees take their cut. The business metrics tools strip away the vanity revenue and show you your real profitability, customer value, and inventory timing.

Thinking about a platform switch? The Shopify planning tools give you a realistic migration budget and help you model the ROI of a redesign before you spend anything. And if your organic traffic has been flat for months, the SEO audit checklist pinpoints exactly what's holding you back — in about 5 minutes.

Every tool is free, runs in your browser, and needs no signup. They're built by the team at WebMedic — a Shopify agency in Malaysia that helps DTC brands grow through smarter ecommerce design, development, and SEO. We use these same calculations in our client work every week. You should have access to them too.
