Customer Acquisition Cost Calculator for Shopify

A good CAC depends heavily on your average order value (AOV) and customer lifetime value (CLV). As a general rule, your CAC should be no more than one-third of your customer lifetime value, so if a customer is worth $300 over their lifetime, aim for a CAC under $100. For first-time purchases, successful Shopify stores typically maintain a CAC that's 20-30% of their average order value. Fashion stores might see CAC between $10-$40, while higher-ticket items like furniture could have CAC of $100-$300. The key is ensuring your CAC allows for profitability when combined with your profit margins and repeat purchase rates.

To calculate accurate CAC, include all marketing and sales expenses divided by the number of new customers acquired. This includes: paid advertising spend across all platforms (Facebook, Google, TikTok, etc.), influencer partnerships and affiliate commissions, content creation costs (photography, video, copywriting), email marketing tools and SMS services, marketing agency or freelancer fees, social media management costs, SEO and content marketing expenses, promotional discounts and free shipping offers used for acquisition, and marketing team salaries if applicable. Don't include costs for retaining existing customers. CAC specifically measures what you spend to acquire NEW customers.

Several strategies can help reduce your CAC: focus on organic traffic through SEO and content marketing, leverage referral programs to turn existing customers into advocates, optimize your paid advertising by testing creatives and targeting, improve your website conversion rate to get more customers from existing traffic, build an email list and nurture leads over time, use retargeting to bring back visitors who didn't purchase, and focus on customer retention to increase lifetime value which effectively lowers your CAC ratio.
