Customer acquisition cost (CAC) measures how much you spend to gain one new customer. It helps you set realistic marketing budgets, evaluate campaign efficiency, and ensure customer acquisition remains profitable as you scale your business.
Divide your total marketing expenses by the number of new customers acquired during the same period. For example, if you spend ₹2,00,000 and gain 500 customers, your CAC is ₹400. Track this monthly or quarterly to spot trends and inefficiencies.
A healthy CAC should be 3x to 4x lower than your customer lifetime value. If your CLTV is ₹12,000, aim for CAC under ₹4,000. Compare against past periods and industry benchmarks to evaluate campaign performance and identify optimization opportunities.
Include all marketing and sales expenses—ad spend, salaries, commissions, tools, and agency fees. Comprehensive tracking gives accurate CAC numbers. Use this full picture to set realistic budgets and evaluate whether acquisition spending stays profitable.
Calculate CAC monthly for fast-moving campaigns or quarterly for strategic reviews. Monthly tracking spots trends quickly and lets you adjust spending in real time. Quarterly tracking provides broader context to evaluate marketing efficiency and performance.
Investors use CAC to evaluate business sustainability and growth potential. Low CAC relative to lifetime value signals efficient marketing and scalability. Show clear CAC trends alongside revenue metrics to prove you can acquire customers profitably at scale.
