Ecommerce Platform Fee Comparison Calculator
Estimate how subscription cost, app spend, and fee rate change platform economics before you commit to a stack.
Run this once per platform option to compare which stack eats less of your revenue before ads and COGS enter the room.
What this tool does
This calculator gives you a quick way to compare monthly platform cost for one ecommerce stack at a time. It is helpful when you want to pressure-test whether Shopify, WooCommerce, BigCommerce, or another option really leaves more room after subscriptions, apps, and payment fees are counted honestly.
When to use this calculator
Use this before you commit to Shopify, WooCommerce, BigCommerce, Wix, Squarespace, Etsy, Amazon, or TikTok Shop. The sticker price rarely tells the whole story. The real comparison is monthly plan cost plus app or plugin spend plus the percentage drag from payment processing, marketplace commissions, and platform surcharges.
This page is now part of the ecommerce platform decision spine: use the Ecommerce Platform Selector first, run this calculator for each finalist, then read the main Shopify vs WooCommerce vs Wix vs BigCommerce comparison before choosing.
How to use it well
Keep revenue assumptions constant across each platform you compare. Then change only the fee stack, plan cost, and app burden. The point is not finding the mathematically cheapest platform in isolation. It is finding the stack that leaves more real room once software cost and transaction drag are included.
A simple comparison pass looks like this:
| Scenario | Monthly revenue | Fee rate to test | Monthly subscription | App/plugin cost |
|---|---|---|---|---|
| Shopify Basic with apps | $25,000 | 2.9% | $39 | $75 |
| WooCommerce on managed hosting | $25,000 | 2.9% | $40 | $40 |
| Marketplace-heavy launch | $25,000 | 8% | $0 | $25 |
| BigCommerce starter stack | $25,000 | 2.9% | $39 | $35 |
Run the calculator once for each row. If two options are close, choose the platform with the cleaner workflow, lower maintenance burden, and better path to the sales channels you actually need.
Decision rules from the result
- If a marketplace looks cheap because there is no monthly subscription, check whether commission rate wipes out the advantage once revenue grows.
- If WooCommerce looks cheapest, add a realistic maintenance or plugin budget before calling it the winner.
- If Shopify costs slightly more but saves setup time, app integration, and checkout friction, the higher monthly cost may still be the better business choice.
- If BigCommerce reduces app spend for a complex catalog, compare total monthly cost instead of only payment fees.
