Clarity over complexity
Selling on modern e-commerce marketplaces like Etsy has never been more accessible—or financially confusing. Between base listing fees, variable transaction commissions, multi-country payment processing rates, regulatory operating taxes, and offsite advertising attribution, calculating what you actually take home on each sale can feel like guesswork.
Most online fee calculators are cluttered with intrusive ads, slow to load, outdated with older fee schedules, or require email signups just to see basic results. We built HarkleTools to change that.
Our core principles
100% Client-Side Privacy
Your financial inputs, item prices, material costs, and margin numbers never leave your device. All calculations execute locally in your browser with zero server data collection.
Policy-Verified Accuracy
We continuously cross-reference official documentation from platforms like Etsy to ensure payment processing rates, auto-renewal rules, and country compliance taxes are always up to date.
Design-Forward Utilities
Inspired by Apple's human interface guidelines, our tools feature clean typography, responsive controls, dark/light themes, and instant visual allocation feedback.
Building the modern seller toolkit
HarkleTools launched with our flagship Etsy Fee & Profit Calculator, but our vision spans across multiple e-commerce ecosystems. We are actively developing pricing, margin, and business calculation utilities for Shopify, eBay, Amazon Handmade, and independent digital storefronts.
