E-commerce Customer Lifetime Value (CLV) Calculator

Calculate how much each customer is worth over their lifetime — and how much you can afford to spend acquiring them.

Customer Lifetime Value (CLV) = Average Order Value × Purchase Frequency × Customer Lifespan × Gross Margin. CLV tells you the maximum you should spend to acquire a customer and still be profitable. Most DTC brands target CLV:CAC ratio of 3× or higher.

Average Order Value

Average revenue per order

Annual Purchase Frequency

How many times the average customer orders per year

Customer Lifespan (Years)

How long the average customer stays active

Gross Margin %

Revenue minus COGS (before shipping, ads, overhead)

Discount Rate (Optional)Optional — calculates present-value CLV

Time value of money — typically 10% for DTC

The Formula

CLV = AOV × Frequency × Lifespan × Gross Margin%

In plain English

CLV = AOV × annual purchase frequency × customer lifespan years × gross margin %.

Worked Example

$85 × 3.5 × 2.5 × 55% = $408 CLV. Max CAC at 3:1 = $136.

Levers to Increase CLV

The three CLV levers: (1) Increase AOV — cross-sell, upsell, bundles add $10–20 per order at scale. (2) Increase purchase frequency — email retention flows, subscriptions, replenishment reminders, and loyalty programmes. (3) Extend customer lifespan — reactivation campaigns, ongoing engagement, and product quality keep customers buying longer.

Small improvements compound: increasing annual purchase frequency from 2.5× to 3× (20% improvement) grows CLV by 20%. Extending average lifespan from 2 to 2.5 years grows CLV by 25%. Both together: CLV grows 50%.

Common Mistakes

⚠️

Using gross margin instead of contribution margin

Gross margin excludes shipping, returns, payment fees, and fulfilment. Use contribution margin (after all variable costs) for a realistic CLV that reflects true customer profitability.

⚠️

Not discounting future cash flows

A customer buying $100 of margin in year 3 is worth less than $100 today. Apply a 10–15% discount rate to CLV for a more accurate present-value calculation, especially for longer customer lifespans.

⚠️

Using CLV to justify unprofitable first-order economics

"The CLV will make it profitable" is the rationalisation behind many failed DTC brands. CLV is a forecast; first-order margins are real. Prove repeat purchase rates with actual cohort data before betting the business on CLV projections.
