Shopify Fee Calculator by Cortexcart

What it does

Hey Product Hunt I'm Jonathan, building Cortexcart. While building our main analytics dashboard, I realized how confusing Shopify's fee structure can be. 2.9% + 30¢? Additional 2% for third-party gateways? Monthly subscription tiers? It’s hard to know what your actual take-home profit is on a $50 order. So I built this Free Calculator. No signup, no email required. Just plug in your revenue and see the breakdown. Hope it helps you save some cash!

Stop losing revenue to broken attribution. CortexCart uses multi-touch attribution to find your revenue leaks, track the full customer journey, and show you exactly which channels drive profit.

Stop guessing your margins. See exactly how much Shopify fees and transaction costs are eating into your profit. Cortexcart connects to Shopify & Stripe to calculate your real-time profit, LTV, and churn every single day. Revenue is vanity" profit is sanity. Many e-commerce founders focus on the &quote;Sales&quote; number in their Shopify dashboard" forgetting that subscription costs, credit card processing fees (2.4% - 2.9%), and third-party transaction penalties (up to 2%) eat into that number significantly. We use the latest 2025 pricing data from Shopify. We calculate your base subscription, apply the correct processing rate based on your plan, and add the fixed per-transaction fee…from cortexcart.com

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
