What It Is

ecalc.tk shows the page title/content as “Eric's eBay Calculators.” Its core offering is a set of online fee calculators for eBay and PayPal use cases. The page states that its rates are “Accurate as of May 2026,” including an eBay fee of 13.6% plus a fixed $0.40 fee, and a PayPal fee of 3.49% plus a fixed $0.49 fee. It also displays reverse-calculation formulas on the page.

Core Features and User Experience

Functionally, it provides an eBay fee calculator, an eBay reverse fee calculator, an eBay + PayPal combined reverse fee calculator, a PayPal fee calculator, and a PayPal reverse fee calculator. Users can enter total received amount, target net amount, or shipping cost to calculate platform fees, profit, or the total price they should set. Its strengths are transparent formulas and a low barrier to use, making it especially suitable for small sellers estimating costs and margins before listing products.

However, from a SaaS or enterprise software perspective, the text does not show any account system, team collaboration, permissions, approvals, reporting, data import/export, third-party integrations, or API capabilities. It is closer to a collection of single-page tools than a full enterprise-grade ecommerce operations platform.

Pricing, Deployment, and Security

The crawled content does not provide information on plans, pricing, free trials, or payment methods. It also does not mention data security, privacy, or compliance certifications. The deployment model can only be understood as an online web tool; there is no description of self-hosting, private deployment, or enterprise cloud deployment. This is not a major issue for users who only need occasional amount calculations, but for businesses that need transaction data retention, multi-user collaboration, or compliance audits, the available information is clearly insufficient.

Pros, Cons, and Who It’s For

Its advantages are that it is lightweight, intuitive, and provides practical forward and reverse calculations around eBay/PayPal fee rates. Its drawbacks are a narrow use case, the possibility that rates may vary by region, category, or account type, and the lack of enterprise software capabilities or service/support information. It is better suited to individual eBay sellers, part-time sellers, and small cross-border merchants needing quick pricing references. It is not suitable as a formal finance, ERP, or order profit accounting system.

Access from China and Alternatives

Access from China cannot be determined from the page content alone, so it is marked as unknown. No payment method information is provided either. If users in China cannot access it reliably, they can consider using the official eBay/PayPal fee documentation, building their own spreadsheet templates, or choosing cross-border ecommerce ERP tools or profit calculator tools as alternatives.
