I kept running the same ecom calculations in spreadsheets — margins, CAC, whether a product was worth testing — and kept getting it wrong or wasting time.
So I built EcomCalc: 8 focused calculators for Shopify sellers, dropshippers, and ecom beginners.
Profit margin · CAC · LTV · Pricing · Shopify fees · Refund impact · Ad metrics · Product viability
No signup. No ads. Just open and use.
Would love to know which calculator is most useful to you — and what's missing.
