Instantly calculate your LTV, LTV:CAC ratio, and payback period — then see how group buying boosts LTV by 25%+ through higher purchase frequency.

With group buying, each customer generates an extra $0 in revenue over their lifetime. Multiply that by your monthly customer count and the impact compounds fast.
Customer Lifetime Value (LTV or CLV) is the total revenue a business can expect from a single customer account over the entire duration of their relationship. It is the single most important metric for understanding whether your business is growing sustainably.
The standard formula is: LTV = Average Order Value × Purchase Frequency × Customer Lifespan. For a profit-based LTV, multiply by your gross margin percentage.
Knowing your LTV alone is not enough. You need to compare it to your Customer Acquisition Cost (CAC). A healthy LTV:CAC ratio means your business can profitably acquire more customers and scale. Below 1:1 means you are subsidizing customers — not building a business.
Group buying campaigns increase purchase frequency because customers stay engaged with ongoing group deals and refer friends to join. Referred customers also have 16–25% higher LTV than ad-acquired customers, since trust is built into the acquisition channel. Our calculator applies a conservative +25% frequency uplift based on aggregated merchant data.
Example: $75 × 2.5 × 2 × 40% = $150 profit LTV

A good LTV depends on your industry and customer acquisition cost. As a general rule, aim for an LTV that is at least 3x your CAC. For Shopify stores, the average LTV ranges from $85 (electronics) to $165 (beauty). If your LTV:CAC ratio is below 1, you are losing money on each customer. A ratio of 3:1 or higher is considered healthy and sustainable.
The most effective strategies to increase LTV are: 1) Increase purchase frequency with repeat-buy incentives and group campaigns, 2) Raise average order value through bundles and upsells, 3) Extend customer lifespan with loyalty programs and subscription models, 4) Use group buying to turn customers into advocates who refer high-value friends, 5) Improve post-purchase experience to reduce churn.
The LTV:CAC ratio compares how much revenue a customer generates over their lifetime (LTV) versus how much it cost to acquire them (CAC). A ratio of 3:1 means each customer brings in 3x what you spent to get them — generally considered the minimum for sustainable growth. Below 1:1 means you are unprofitable per customer. Above 5:1 suggests you may be under-investing in growth.
Group buying increases LTV in three ways: 1) Higher purchase frequency — group buyers return 25% more often because they are socially committed and receive group campaign invites, 2) Higher AOV — group participants tend to add more to cart to hit group thresholds, 3) Referred friends have higher LTV than ad-acquired customers because trust is pre-built through the referral. Studies show referred customers have 16–25% higher LTV than non-referred customers.
The CAC payback period is how many months it takes to recover the cost of acquiring a customer through their gross profit contribution. Formula: CAC ÷ (Monthly Revenue per Customer × Gross Margin). For example, if your CAC is $50 and a customer generates $20/month in gross profit, your payback period is 2.5 months. A payback period under 12 months is ideal for most ecommerce businesses.
