Common questions
What's a healthy LTV:CAC ratio?
A common SaaS rule of thumb is 3:1 — that is, lifetime value should be at least three times customer acquisition cost. Below ~1.5:1 you're losing money or barely breaking even on each customer; above ~5:1 you're typically under-investing in growth.
Should I use gross margin or net margin?
Use gross margin for product-level pricing and unit economics. Use net margin when you want to compare overall company profitability after operating expenses, taxes and interest. The margin calculator handles all three.
