Calculate customer acquisition cost (CAC) from marketing and sales spend. Digital marketing runs on unit economics. These calculators turn raw campaign numbers into the metrics that matter — what you pay per result, what each customer is worth and whether your ads are profitable.
How to use the Customer Acquisition Cost Calculator
- Enter your marketing spend, your sales spend, your new customers.
- Results update automatically as you type; you can also press Calculate.
- Read the output: cac, total acquisition spend.
- Use the 📊 chart to see the result visually, then copy or share it.
Formula and method
Worked example
With marketing spend = $8,000, sales spend = $4,000, new customers = 60, the Customer Acquisition Cost Calculator returns cac: $200.00; total acquisition spend: $12,000.00.
Tips for better results
- Track LTV:CAC — a ratio of 3:1 or higher is a common healthy benchmark.
- ROAS must exceed 1 ÷ margin to be profitable, not just exceed 1.
- Ad revenue varies widely by niche, country and season — use your own historical RPM when you have it.
⚠️ Revenue estimates depend on your traffic quality, niche and ad network policies; actual earnings will differ.
