    How to Calculate Customer Acquisition Cost and Budget with the CAC Calculator

    Calculate customer acquisition cost from marketing and sales spend, estimate the budget required for a customer goal, or forecast customers from budget.

    Formula

    CAC = sales and marketing cost / new customers

    How to use the result

    Pair CAC with gross-profit LTV and payback months before deciding whether acquisition can scale.

    Include sales payroll and tools when measuring blended CAC; channel CAC can use narrower costs. Inputs and calculations stay in this browser.

    Understanding CAC

    CAC = (Total Marketing Cost + Total Sales Cost) / New Customers Acquired

    Customer Acquisition Cost (CAC) is a critical metric that tells you how much you spend on average to acquire a new customer.

    Marketing Costs include advertising, content creation, SEO, social media, email marketing, and other promotional expenses.

    Sales Costs include sales team salaries, commissions, tools, and other direct selling expenses.

    CAC vs CLV: Compare your CAC to Customer Lifetime Value (CLV). A healthy ratio is typically 1:3 (CAC:CLV), meaning customers should generate 3x what you spent to acquire them.

    What is CAC (Customer Acquisition Cost)?

    CAC is the average amount you spend to acquire one new customer. It combines marketing and sales costs and is most useful when you measure it over a consistent time window and compare it against LTV/CLV. A “good” CAC depends on your margins, payback period, and retention.

    How to Calculate Customer Acquisition Cost and Budget

    Calculate CAC

    1. Enter your Total Marketing Cost and Total Sales Cost for the same period.
    2. Enter New Customers Acquired in that period.
    3. Use the output CAC to benchmark channels and spot efficiency changes over time.

    Required Budget

    1. Set a Target CAC you believe is sustainable given your margins and payback goals.
    2. Enter expected new customers and calculate the budget needed.
    3. Use this view for planning quarterly spend and sales capacity.

    Customers Needed

    1. Enter an Available Budget and a Desired CAC.
    2. Use the result to understand how many customers your budget can support.
    3. Compare the output with your pipeline/traffic forecasts to check feasibility.

    Measurement tips

    • Include only acquisition-related costs; exclude retention spend unless you intentionally treat it as acquisition.
    • Use fully-loaded costs when possible (tools, agencies, salaries) to avoid underestimating CAC.
    • Pair CAC with payback period and CLV so you optimize for profit, not just cheap customers.
