Everything you need to know about Customer Acquisition Cost — from the formula and benchmarks to strategies for reducing CAC and improving your LTV:CAC ratio.
Customer Acquisition Cost (CAC) is the total amount a business spends to acquire one new paying customer. It includes all marketing and sales expenses — ad spend, salaries, software, agency fees, and more — divided by the number of new customers gained in the same period.
CAC = Total Marketing & Sales Costs ÷ Number of New Customers Acquired. For example, if you spent ₹2,10,000 across all acquisition channels and gained 700 new customers, your CAC is ₹300.
A 'good' CAC depends on your industry, product price, and customer lifetime value (LTV). For e-commerce, ₹300–₹2,000 is typical. For SaaS, ₹2,000–₹20,000 is common. The most important benchmark is your LTV:CAC ratio — a ratio of 3:1 or higher is considered healthy.
The LTV:CAC ratio compares how much revenue a customer generates over their lifetime (LTV) to how much it costs to acquire them (CAC). A 3:1 ratio means you earn three times what you spent to acquire each customer, which is the widely accepted benchmark for sustainable growth. Below 1:1 means you're losing money on every customer.
Include all direct and indirect acquisition costs: paid advertising (Google, Meta, LinkedIn), content production and SEO spend, sales team salaries and commissions, marketing software and CRM tools, agency or freelancer fees, event sponsorships, and any other costs directly tied to acquiring new customers.
Most businesses calculate CAC monthly or quarterly to track trends. Measuring it against the same periods allows you to see whether CAC is rising or falling as you scale. If you run campaigns, calculate CAC per campaign to identify which channels are most efficient.
The most effective ways to reduce CAC include: investing in SEO and content marketing (organic channels with compounding returns), building a referral or loyalty program (word-of-mouth has the lowest CAC), improving landing page and funnel conversion rates, tightening your ideal customer profile (ICP) targeting, and shortening your sales cycle.
Blended CAC divides your total acquisition spend by all new customers regardless of channel — it gives you an overall efficiency metric. Channel CAC calculates cost per customer for each individual channel (e.g., Google Ads, organic, referrals). Channel CAC helps you identify which channels are most cost-efficient so you can reallocate budget accordingly.

Strong customer retention lowers your blended CAC over time. When existing customers return and refer others, you acquire more revenue without proportionally increasing your acquisition spend. Tools like loyalty programs, gift cards, and referral systems — like those offered by 99minds — directly improve your CAC efficiency by turning customers into a growth channel.
