Understanding the Golden Ratio (LTV:CAC)
The LTV to CAC ratio measures the relationship between the lifetime value of a customer and the cost of acquiring that customer. A ratio of 3:1 is considered ideal for SaaS businesses. If it's lower, you are spending too much on marketing. If it's higher (e.g., 5:1), you are likely underinvesting in growth.

SaaS Project Economics Made Simple
Running a SaaS startup requires a clear view of customer economics. The most important metrics are LTV (Lifetime Value), CAC (Customer Acquisition Cost), and the Golden Ratio that compares them.
Our SaaS Project Economics Calculator helps you measure how much each customer is worth, how much you spend to acquire them, and whether your growth strategy is sustainable. By entering your data, you can instantly see if your LTV to CAC ratio meets the industry benchmark for healthy SaaS growth.
Understanding these numbers is critical. A strong LTV means customers stay longer and generate more revenue. A controlled CAC ensures you are not overspending on marketing and sales. The Golden Ratio shows if your business model is scalable. With this calculator, founders and finance teams can make smarter decisions about pricing, marketing spend, and long‑term profitability.
Use this tool to track your startup’s performance, adjust strategies, and build a SaaS business that grows with confidence.
