Compare customer lifetime value across industries only after aligning the customer unit, margin, observation horizon and retention assumptions. Work through an illustrative cohort comparison and the checks needed before using an outside reference.
Customer lifetime value by industry is comparable only after the customer unit, margin, horizon and retention definitions match. A published dollar figure cannot tell you whether your customers are more valuable when one calculation counts revenue and another counts contribution. Start with a common measurement basis, then decide whether an outside reference belongs beside it.
The business relationship determines what a customer is and how value arrives. A telecom account can contain several lines; a retailer may observe long gaps between seasonal purchases; a maintenance business may work through renewable contracts. Treating each as an identical recurring customer hides the differences that drive the calculation.
| Business setting | Customer unit to confirm | Evidence of activity | Comparison question |
|---|---|---|---|
| Telecom | Account or individual service line | Active services and recurring charges | Does the reference count lines or relationships? |
| Retail | Identified shopper or household | Completed purchases after linked returns | Does the reference allow for buying cadence? |
| Maintenance services | Contract or customer organization | Work delivered under the relationship | Does renewal preserve the same customer identity? |
These are measurement choices to document, rather than universal industry definitions. Customer lifetime value for telecom covers the account-versus-line issue in its own setting. The general lifetime value definition provides the shared starting point.
An observed cohort measure adds the value actually earned during a fixed period. A future lifetime estimate adds expected contribution over the remaining relationship, with assumptions about retention, purchase patterns, cost and timing. Give those measures different labels even if both appear in the same management report.
Published methods make their retention assumptions explicit. Bruce Hardie's contractual CLV note derives value measures using a stated distribution of customer lifetimes. A retail cohort with no cancellation event needs a different treatment of continued activity from a contractual relationship.
For a comparison you can rebuild from an export, start with this narrower calculation:
Observed cohort contribution = Net sales − Direct delivery costs − Other included variable service costs
Observed contribution per original customer = Observed cohort contribution / Original cohort customers
The original denominator includes customers who later stopped buying. Dividing only by survivors would remove the effect of losses from the per-customer result. Use a complete observation window for every cohort before comparing them.
The following figures describe illustrative US businesses, not published industry benchmarks. Each cohort is observed for the first 12 months after acquisition. Sales are net of returns and credits; costs include direct delivery plus the stated variable fulfillment or service costs. Corporate overhead and acquisition costs are excluded consistently, and amounts are undiscounted.
| Illustrative business | Original customers | Net sales (USD) | Direct delivery costs (USD) | Other variable costs (USD) | Contribution (USD) | Contribution per original customer (USD) |
|---|---|---|---|---|---|---|
| Telecom accounts | 100 | 96,000 | 57,600 | 14,400 | 24,000 | 240 |
| Retail shoppers | 100 | 60,000 | 36,000 | 12,000 | 12,000 | 120 |
| Maintenance customers | 50 | 120,000 | 72,000 | 18,000 | 30,000 | 600 |
| Total | 250 | 276,000 | 165,600 | 44,400 | 66,000 | 264 |
For telecom, 96,000 − 57,600 − 14,400 = $24,000, and 24,000 / 100 = $240 per original account. Retail produces 60,000 − 36,000 − 12,000 = $12,000, or $120 per shopper. Maintenance produces 120,000 − 72,000 − 18,000 = $30,000, or $600 per customer.
The pooled figure is 66,000 / 250 = $264, calculated from totals. All displayed dollar values are exact for these illustrative inputs. The maintenance result is larger, but that alone does not prove better retention or a better acquisition decision. Contract size and service scope also differ.
Suppose the retail comparison omits the other variable costs while keeping every sale and customer unchanged. Its reported value becomes 60,000 − 36,000 = $24,000, or 24,000 / 100 = $240 per shopper. That is double the contribution figure under the common definition, created entirely by excluding the $12,000 cost column.
No customer bought more. No cost disappeared. The comparison changed its scope. Revenue alone would give 60,000 / 100 = $600 per shopper, a third measure that should not share the same label.
This is why customer profitability versus lifetime value keeps period economics separate from future relationship value. For the full calculation choices, use how to calculate LTV.
Before adding a published number, record the source date, population and exact calculation. Ask whether its customers are newly acquired or already established, whether the horizon is observed or projected, and whether the figure is a mean, median or ratio of totals. Missing definitions are a reason to withhold the comparison.
Record the currency and period too. Confirm whether acquisition costs, returns, servicing and overhead are included. If the reference discounts future cash flows, document the rate and timing convention rather than placing it beside an undiscounted observed total without explanation.
Do not convert a recent churn rate into a lifetime mechanically. Hardie's note on reciprocal churn calculations explains why reported average lifetime is not generally the reciprocal of churn. Your evidence card should identify the retention assumption instead of letting it remain hidden. Customer lifetime value statistics addresses the separate job of assessing published figures.
The example's contribution reconciles as 276,000 − 165,600 − 44,400 = $66,000. Its customer count reconciles as 100 + 100 + 50 = 250. In your file, tie the sales and cost totals to the underlying reports and account for unmatched customer IDs before accepting a per-customer result.
Finance should own the cost definition and reconciliation. The commercial owner should confirm the relationship unit and acquisition cohort. Together they can decide whether an outside reference has a sufficiently similar basis to inform planning.

See customer profitability for the supporting business context.
No single dollar value is meaningful across businesses with different customer units, margins and purchase patterns. Start with your company's cohorts and a documented value definition. An outside figure is useful only when its measurement basis is clear enough to make the comparison defensible.
Only after reconciling the costs between them. Revenue value excludes the expense of delivering and servicing those sales. A profit-based measure needs a stated cost scope, including whether variable fulfillment, support and acquisition costs are included. Label the difference before comparing the figures.
It is an observed value over a fixed horizon, rather than a complete estimate of future lifetime value. It is useful for comparing mature cohorts consistently. Extending it into the future requires explicit assumptions about retention, buying frequency, margins and the length of the remaining relationship.
