How to use this calculator

Enter AOV, gross margin, expected lifetime purchases, and CAC. The calculator estimates lifetime gross profit, LTV:CAC ratio, and customer value health.

What the result means

A strong LTV means each buyer produces enough lifetime profit to justify acquisition cost. Low LTV means the business needs better repeat purchases, margin, or AOV.

LTV = AOV × Margin × Lifetime Purchases. LTV:CAC = LTV / CAC.

A ratio above 3 is strong, 1.5 to 3 is workable, and below 1.5 is weak.

Example calculation

With $45 AOV, 35% margin, 3 lifetime purchases, and $8 CAC, LTV is $47.25 and LTV:CAC is 5.91.

Tips for better results

  • Increase repeat purchases with post-purchase offers.
  • Bundle related products to raise AOV.
  • Do not scale CAC until LTV is clearly above acquisition cost.

FAQ

How do I calculate customer LTV for eBay buyers?

Multiply average order value by gross margin and expected lifetime purchases, then compare that value against customer acquisition cost.

What is a good LTV to CAC ratio for eBay?

A ratio above 3 is generally strong, 1.5 to 3 is acceptable, and below 1.5 suggests acquisition spending is risky.

How can I increase repeat purchases on eBay?

Use accurate listings, strong service, product inserts where allowed, category-focused inventory, and follow-up offers to encourage repeat buying.

Is eBay customer lifetime value important for resellers?

It matters most when buyers can return for similar products. One-time collectible sales may rely more on item-level profit than customer LTV.

Why is my eBay LTV lower than my CAC?

LTV may be low because of thin margins, low repeat purchases, weak AOV, high ad costs, or poor customer retention.
