LTV:CAC Ratio Benchmarks by Stage & ARR Band

Calculate your LTV:CAC ratio

LTV = ACV × Gross Margin % × Customer Lifetime (years). Divide by CAC.

The 3× rule — and when it doesn't apply

The widely cited 3:1 minimum applies to growth-stage companies ($5M–$50M ARR). Seed-stage companies often operate below 3× while finding PMF — acceptable if the trend is improving quarter over quarter. Above $50M ARR, best-in-class companies sustain 6–10× ratios because expansion revenue compounds LTV without proportional CAC increases. A 120% NRR customer renews and expands for free — that compounds the numerator of LTV:CAC with every passing year.
