MarginLab Calculator Library
Profit, pricing, inventory, finance, marketing, customer economics and ecommerce calculators.
Explore Tools →Built around profit, not vanity metrics.
Economic context
Metrics are explained through the decisions they influence, not as isolated definitions.
Connected knowledge
Lessons, research, business analysis, cases, definitions and tools reinforce one another.
Practical reasoning
Numerical examples and trade-offs turn abstract ecommerce metrics into usable business thinking.
How the Academy works.
Is MarginLab Academy free?
Yes. Academy learning resources are designed to be accessible without a paid MarginLab subscription.
Where should I start?
If you want structured learning, begin with Lessons. For a specific commercial question use Business Articles; for deeper research use Long Guides.
What is the difference between Academy and Tools?
Academy explains concepts and business reasoning. Tools is the separate calculator library for applying those concepts to numbers.
Is the Academy only for Shopify stores?
No. MarginLab Academy focuses on ecommerce profitability principles that apply across stores, marketplaces and business models, while some resources use Shopify-specific examples where useful.
Understand profitability. Then measure it in your own store.
MarginLab turns the same economic principles taught in the Academy into store-level profit intelligence, risk signals and actionable decisions.
