How eCRATER fees actually work
eCRATER charges 2.9% only on sales originated through the eCRATER marketplace, with no monthly or listing fees. Every seller calculator that skips one of these layers will overstate your profit — sometimes by 10–20 percentage points of margin. This tool applies the full stack: 2.9% on marketplace-driven sales, 0% on direct traffic. If your accountant tells you your margin is lower than what a marketplace listing tool shows, this is usually why.
Who sells well on eCRATER
Hobbyist sellers, low-volume side businesses. Sellers who match those categories tend to see the strongest unit economics here because their cost per acquisition stays low and the platform's organic traffic does the heavy lifting. If you sell outside those lanes you can still succeed, but you'll need to budget more for ads and own audience.
How shoppers find products on eCRATER
eCRATER search, Google Shopping feed. That changes how you should price: in search-driven marketplaces, undercutting competitors by 5% can dramatically lift conversion and offset your margin loss with volume. In curated or recommendation-driven platforms, premium pricing with great photos and reviews often outperforms a price war.
Using this calculator with your real data
Pull last 30 days of orders from your eCRATER dashboard. Average the item price, shipping charged, and your real COGS (don't forget returns and damaged-in-transit). Punch them in. If your calculated net profit doesn't match what hit your bank account, the gap is usually returns, refund retention fees, currency conversion, or a category-specific fee. Adjust the misc cost field to model that.
Optimising margin on eCRATER
Three levers move margin most: free store builder, Google Shopping feed. Test each one separately — change one variable, hold the rest constant, measure for 14 days minimum because shopper behaviour swings weekly. Sellers who treat their eCRATER shop like a real P&L instead of a hobby grow ~3x faster on average over a 12-month horizon.
Frequently asked questions
What fees does eCRATER charge sellers?
2.9% on marketplace-driven sales, 0% on direct traffic.
Does this calculator include taxes?
No — sales tax / VAT / GST is collected from the buyer and remitted (in most cases) by eCRATER on your behalf, so it doesn't hit your margin. Add income tax on your net profit separately at your country's rate.
Are eCRATER fees negotiable?
For most sellers, no — they're set by the platform. High-volume sellers, brand-registered sellers, or enterprise accounts sometimes negotiate reduced commissions or waived fees, but you typically need to clear $250K+/yr in gross sales to start that conversation.
How accurate is this calculator?
It uses eCRATER's publicly-published rate card as of 2026. Category-specific commissions, returns, refund retention fees, and currency conversion can adjust your real net by 1–3 percentage points. Always cross-check against your monthly statement.
What's a healthy net margin on eCRATER?
For most product categories on eCRATER, a 20–30% net margin after all fees, COGS, ads and returns is healthy. Below 15% you'll struggle to absorb returns and reinvest in inventory; above 35% you're either underpriced for the platform or you have a moat worth protecting.
