Margin Bench / Our approach
About Margin Bench
What this workspace offers, what is still in preview, and how to use it responsibly.
A workspace for thinking through the numbers
Margin Bench provides 33 business calculators covering ecommerce and profit, marketing returns, and SaaS retention. They are local, deterministic tools: the same accepted inputs and formula produce the same numeric result. Calculations run in your browser, without a remote calculation API, connected business account, or sign-in.
Each tool explains its inputs, formula, worked example, and limitations. The purpose is to make a specific calculation easier to inspect, not to replace bookkeeping, campaign measurement, or a financial model.
Start with a question, not a target
If you are pricing a product, decide whether you need markup, contribution margin, or net margin before choosing a calculator. If you are evaluating advertising, distinguish attributed revenue from profit. For subscriptions, separate recurring revenue from cash collected and estimated lifetime value from observed customer outcomes.
The business guides work through these distinctions with illustrative numbers. Browse ecommerce and profit tools, marketing tools, or SaaS tools when you have a defined question and matching inputs.
Transparent scope
No professional credentials, independent certification, or named expert review are claimed for these pages. Examples are illustrative arithmetic, not customer case studies, market benchmarks, or evidence of likely earnings. Read the methodology before relying on a result and the terms of use for the scope of the service.
