Unit Economics Calculator

Work out your Customer Acquisition Cost (CAC), Customer Lifetime Value (LTV), the LTV:CAC ratio, and your CAC payback period — the three numbers investors and your own gut-check ask for first. No password, and nothing you enter ever leaves your browser.

Unit Economics Calculator — CAC, LTV & Payback Period
Planning aid, not an audited metric. This calculator uses the standard, widely-used unit-economics formulas (CAC = spend ÷ new customers; LTV = ARPU × gross margin % × average customer lifetime). The LTV:CAC benchmarks shown (3:1 as "healthy") are commonly-cited investor rules of thumb, not a guarantee — a good ratio for your specific business depends on your industry, funding stage and growth ambitions.

    Disclaimer: This is a self-help planning aid, not an audited or certified metric. It assumes a constant monthly churn rate (so average customer lifetime = 1 ÷ monthly churn rate) and a constant ARPU over a customer's lifetime — real businesses see both change over time, especially with expansion revenue or cohort-based pricing. Aggarwal Abhishek & Co. does not certify these figures — for a proper MIS/Virtual CFO setup tailored to your business, please get in touch.
