Unit Economics Calculator
Compute key unit economics metrics: contribution per transaction, contribution margin, LTV (Customer Lifetime Value), CAC (Customer Acquisition Cost), and LTV:CAC ratio. It applies the standard formula: LTV = AOV × Purchase Freq × Lifetime × Gross Margin% | LTV:CAC = LTV / CAC.
Whether you are facing an important financial decision or simply need a fast, reliable answer, this calculator eliminates manual mathematical errors and delivers instant, accurate results. It is designed around verified industry standards and mathematical best practices, making it suitable for students, professionals, and everyday users alike.
Use the inputs above to enter your values — results update in real time. Below the result, you will find a step-by-step formula breakdown, a worked numerical example, and common mistakes to avoid. Note: Unit economics use assumed customer behavior metrics. Actual values depend on cohort data and business model.
