About Unitly

Unitly is a free library of business calculators for e-commerce, SaaS, marketing and general business decisions. It exists because the core numbers of a business — profit, margin, break-even, ROAS, churn, LTV — should take seconds to compute, not spreadsheets.

Who it's for: store owners, SaaS founders, marketers, freelancers, agencies, product managers, students, and anyone researching a business idea.

How we build: every calculator uses standard, documented formulas shown on the page. Inputs are validated, edge cases (division by zero, empty fields, extreme values) are handled explicitly, and all computation runs locally in your browser. Nothing you enter is transmitted or stored on a server.

Honesty policy: we don't display fake statistics, testimonials or usage numbers. Results are informational estimates, not financial, legal, accounting or investment advice.
