Lifetime Value Calculator
Estimate customer lifetime value from purchase amount, purchase frequency, margin, retention, or customer lifespan. LTV is useful for deciding how much you can afford to spend on marketing, service, retention, and acquisition.
Lifetime Value Planning Tips
Estimate customer lifetime value. Use current figures that match the same reporting period, and include the costs, fees, revenue, customers, or transactions named in the form. Test more than one set of inputs to see how the lifetime value changes under stronger and weaker business conditions.
Quick Guide
- Use figures from the same month, quarter, or year.
- Include all costs or transactions requested by this calculator.
- Compare a conservative scenario with an optimistic one.
- Update the calculation as your business data changes.
Customer Economics
Compare what customers cost to acquire with what they may be worth.
Growth Planning
Use CAC and LTV to evaluate campaigns and retention.
Profit Check
Read the result with margin, payback period, and repeat purchases.
Lifetime Value Formula and Inputs
LTV can be estimated from average order value × purchase frequency × customer lifespan × margin.
Business metrics are most useful when the inputs come from the same time period and the same definition. Before comparing results, decide whether you are measuring revenue, profit, customers, orders, units, leads, or another specific business event.
| Input | How to Use It |
|---|---|
| Average order value | Use a value from the same campaign, product, period, or business scenario as the other inputs. |
| Purchase frequency | Use a value from the same campaign, product, period, or business scenario as the other inputs. |
| Gross margin | Use a value from the same campaign, product, period, or business scenario as the other inputs. |
| Customer lifespan or retention | Use a value from the same campaign, product, period, or business scenario as the other inputs. |
Worked Lifetime Value Example
If a customer spends $80 four times per year for three years, gross revenue LTV is $960 before margin or servicing costs.
After calculating one result, change one input at a time. This makes it easier to see whether price, cost, volume, conversion rate, retention, ad spend, or labor is driving the business outcome.
How to Interpret the Result
LTV helps decide how much acquisition spend can be justified, but it depends heavily on retention, margin, and real purchasing behavior.
A business calculator can point you toward better decisions, but the number should be reviewed with context: margin, cash timing, customer quality, seasonality, capacity, and whether the result can repeat.
Common Lifetime Value Mistakes
- Using revenue LTV when profit LTV is needed.
- Overestimating retention.
- Ignoring refunds or support costs.
- Averaging together very different customer groups.
When to Use the Lifetime Value Calculator
Use the Lifetime Value Calculator when you need to calculate customer lifetime value for a specific business decision or reporting period. It is especially helpful for reviewing customer economics, comparing acquisition channels, measuring retention, planning growth targets, or testing whether the expected value of a customer supports current marketing and service costs. Enter values such as Average order value, Purchase frequency, Gross margin, Customer lifespan or retention from the same product, campaign, team, customer group, or accounting period so the result remains meaningful. For tax filings or formal financial reporting, verify the figures with your accounting records or a qualified professional.
Lifetime Value Calculator FAQs
How do I calculate customer lifetime value?
Use the relationship: LTV can be estimated from average order value × purchase frequency × customer lifespan × margin. Enter values from the same product, campaign, customer group, or reporting period so the result represents one consistent business scenario.
Which inputs matter for the Lifetime Value?
The main inputs are Average order value, Purchase frequency, Gross margin, Customer lifespan or retention. Check each value carefully because changing cost, price, volume, rate, or time period can materially change the result.
Can you give a lifetime value example?
If a customer spends $80 four times per year for three years, gross revenue LTV is $960 before margin or servicing costs.
How should I interpret the result?
LTV helps decide how much acquisition spend can be justified, but it depends heavily on retention, margin, and real purchasing behavior.
What are common lifetime value mistakes?
Using revenue LTV when profit LTV is needed. Overestimating retention. Ignoring refunds or support costs. Averaging together very different customer groups.
When should I recalculate customer lifetime value?
Recalculate whenever prices, costs, fees, sales volume, traffic, staffing, customer behavior, or the reporting period changes. Use the calculator for planning, then verify official figures in your bookkeeping, analytics, payroll, or accounting system.
