About MerchSites
Empowering online sellers, independent store owners, and merchandise creators with exact, transparent financial tools.
Our Core Mission
MerchSites was created to solve a widespread problem in the ecommerce community: sellers launching products with false confidence based on oversimplified margin formulas. When sellers multiply product unit cost by two to set a retail price, they miss the cumulative impact of landed freight, custom packaging, payment processing, platform fees, return reserves, and advertising CAC.
Our mission is simple: Know your real profit before you sell.
Built for Reliable Financial Math
Financial calculations can produce unexpected rounding errors when standard floating-point math is used carelessly. MerchSites uses decimal-safe calculation methods, consistent rounding rules, and automated formula tests to provide dependable estimates for product pricing and profitability planning.
Privacy-First Client-Side Processing
Your product costs, supplier pricing, margin targets, and sales projections stay 100% private. All calculations occur inside your browser using client-side JavaScript. We never store, transmit, or monetize your business financial inputs.
All calculations provided by MerchSites are for planning, educational, and estimation purposes only. MerchSites does not provide certified accounting, tax, legal, or financial advising services. Consult a qualified professional for official corporate financial statements.
Use MerchSites Calculators on Your Website
Selected MerchSites calculators can be embedded into ecommerce websites, seller resource pages, industry associations, blogs, and business education platforms. An embedded calculator can help visitors make better pricing decisions while giving your website a useful, interactive resource.
