Why retention matters so much:
A 5% increase in retention can increase profits by 25-95% (Bain & Company). Existing customers are 50% more likely to buy again and spend 31% more than new customers. Focus on loyalty programs, personalized offers, and post-purchase engagement.

Share Your CLV Score
With a CLV of $1248, you can afford up to $416 per customer acquisition. DealCraft automates the retention levers that make every dollar count:
Understanding CLV is the foundation of profitable growth. Master these concepts to make better acquisition and retention decisions.
CLV = Average Order Value x Purchase Frequency x Customer Lifespan x Profit Margin. This tells you the total profit each customer generates. If CLV is $1,000 and CAC is $200, you have a 5:1 ratio — excellent unit economics.
The gold standard for unit economics. A 3:1 ratio means each customer generates 3x the profit vs. acquisition cost. Below 1:1 means you're losing money. Most profitable Shopify stores target 3:1 to 5:1.
How many months until a customer's profit covers their acquisition cost? Shorter is better — under 6 months is healthy for most e-commerce businesses. This determines your cash flow sustainability.
A 5% increase in retention can boost profits by 25-95% (Bain & Company). Existing customers spend 31% more and are 50% more likely to buy again. Retention is the highest-leverage growth lever.
Customer Lifetime Value (CLV or LTV) is the total profit a customer generates for your store over their entire relationship with you. The formula is: CLV = Average Order Value x Purchase Frequency x Customer Lifespan x Profit Margin. For example, if a customer spends $65 per order, buys 2 times per month, stays for 2 years, and your margin is 40%, their CLV is $1,040.
A CLV:CAC ratio of 3:1 or higher is considered excellent. This means each customer generates 3x the profit compared to what you spent acquiring them. A ratio of 2:1 is good but has room for improvement. Below 1:1 means you're losing money on every new customer. Most profitable Shopify stores target 3:1 to 5:1.
Retention has a massive impact on CLV. A 5% increase in retention can boost profits by 25-95% (Bain & Company). This is because retained customers buy more frequently, spend more per order (31% more on average), and cost less to serve. Existing customers are also 50% more likely to try new products and refer others.
CAC = Total Marketing Spend / Number of New Customers Acquired. Include all costs: ad spend, agency fees, content creation, tools, and salaries of marketing team. For example, if you spend $5,000/month on ads and get 100 new customers, your CAC is $50. Compare this to your CLV to ensure profitable unit economics.
Focus on four levers: (1) Retention — loyalty programs, personalized offers, post-purchase emails. (2) Average Order Value — upsells, bundles, free shipping thresholds. (3) Purchase Frequency — subscription models, replenishment reminders, seasonal promotions. (4) Profit Margin — optimize COGS, reduce returns, premium positioning. DealCraft helps you create smart discount rules that boost all four levers.
