Customer Lifetime Value Calculator: method, checked example and practical limits
Estimate gross-profit customer value from order economics, purchase frequency and retention. The modeled value depends on customer behavior remaining consistent over the forecast horizon.
Inputs used by this calculator
Customer Lifetime Value Calculator uses the fields below. The starting values reproduce the page example; replace them with values from the same units and time period before using the result.
| Input | Starting example | Accepted value | How it is used |
|---|---|---|---|
| Average order value | 80 | 0 to 1000000000000 | Supplies the average order value quantity used by the published equation or result breakdown. |
| Gross margin (%) | 60 | 0 to 100 | Supplies the gross margin (%) quantity used by the published equation or result breakdown. |
| Purchases per year | 4 | 0 to 1000000 | Supplies the purchases per year quantity used by the published equation or result breakdown. |
| Average customer lifetime (years) | 3 | 0 to 1000 | Selects the unit or conversion path used by Customer Lifetime Value Calculator. |
| Acquisition cost | 50 | 0 to 1000000000000 | Supplies the acquisition cost quantity used by the published equation or result breakdown. |
Inputs and measurement conventions
The quantities used on this page are Average order value, Gross margin (%), Purchases per year, Average customer lifetime (years), Acquisition cost. Start with values for the same situation and read the units attached to each field. The field reference below shows supported choices and numerical limits.
Churn and retention must use matching intervals. Revenue lifetime value differs from contribution-margin value and discounted cash flow.
Method and equation
Multiply average order value, gross-margin fraction, annual purchase frequency and assumed customer lifetime to estimate contribution value.
Customer Lifetime Value Calculator uses the following stated relationship: LTV = order value × gross margin × annual frequency × lifetime. Its assumptions determine which question the answer can resolve.
LTV = order value × gross margin × annual frequency × lifetimeWorked calculation with the starting values
Average order value: 80; Gross margin (%): 60; Purchases per year: 4; Average customer lifetime (years): 3; Acquisition cost: 50. These starting values give 576 estimated gross-profit LTV. The calculation breakdown is Lifetime revenue: 960; Gross-profit LTV: 576; LTV:CAC: 11.52; Value after CAC: 526.
$80 × 60% × 4 purchases × 3 years produces $576 gross-profit LTV.
Reading the answer
The modeled value depends on customer behavior remaining consistent over the forecast horizon.
Lifetime revenue: 960; Gross-profit LTV: 576; LTV:CAC: 11.52; Value after CAC: 526. These intermediate quantities make the stated Customer Lifetime Value Calculator model inspectable; they should be read together with the main answer rather than treated as independent guarantees.
Common errors and model boundaries
Churn and retention must use matching intervals. Revenue lifetime value differs from contribution-margin value and discounted cash flow.
This simple model does not discount future cash flows or model changing retention by cohort.
Independent verification and next decision
Only when the CLV definition accounts for the relevant margin, acquisition scope, time horizon and discount assumptions.
For the Customer Lifetime Value Calculator method, compare LTV = order value × gross margin × annual frequency × lifetime with the starting inputs and the calculation table. The linked U.S. Small Business Administration: business guide and Federal Trade Commission: advertising and marketing basics references identify the relevant definitions, conventions or domain limitations. Retain intermediate precision when comparing a manually worked answer.

Frequently asked questions
Can I compare this directly with CAC?
Only when the CLV definition accounts for the relevant margin, acquisition scope, time horizon and discount assumptions.
Which relationship does the Customer Lifetime Value Calculator use?
Multiply average order value, gross-margin fraction, annual purchase frequency and assumed customer lifetime to estimate contribution value. The displayed relationship is LTV = order value × gross margin × annual frequency × lifetime.
What do the starting values produce in the Customer Lifetime Value Calculator?
Average order value: 80; Gross margin (%): 60; Purchases per year: 4; Average customer lifetime (years): 3; Acquisition cost: 50. These starting values give 576 estimated gross-profit LTV. The calculation breakdown is Lifetime revenue: 960; Gross-profit LTV: 576; LTV:CAC: 11.52; Value after CAC: 526.
