Customer Lifetime Value Calculator
Estimate lifetime value from average order value x purchase frequency x customer lifespan, or from monthly revenue divided by churn, then compare the result with benchmark range and optional CAC before changing acquisition or retention spend.

Benchmark-range lifetime value
$950
LTV sits inside the usual industry band. Read CAC and retention before deciding whether to scale harder.

Industry benchmark range
$250 to $1,200
Annual revenue / customer

Gross-profit LTV

Gross-profit LTV/CAC
4.59:1
3:1 target CAC
$183.67
Revenue lifetime value is $950 on $380 of annual customer revenue. Current LTV/CAC is 4.59:1.
LTV is within the typical e-commerce range. The next question is whether gross margin, retention, and CAC still support faster growth.
Industry read: Within the typical E-commerce range
Relative to a 3:1 target, current CAC is below target by $63.67.
Action Checklist
- Gross margin is doing a lot of work in the profit view. Even modest pricing or fulfillment improvements can lift gross-profit LTV without adding more customers.

This section substitutes your current inputs into the selected CLV method so you can check whether revenue, retention, and CAC are pointing in the same direction.

Assumption notes
- Revenue, frequency, lifespan, and CAC should all describe the same customer definition.
- Subscription LTV assumes a stable monthly churn pattern, which is a planning shortcut rather than a full cohort forecast.
- Benchmark ranges are directional because businesses define CLV slightly differently across revenue and profit views.
Current scenario highlights
- Status: Benchmark-range lifetime value
- Industry read: Within the typical E-commerce range
- Target ratio: 3:1
- Target CAC at 3:1: $183.67

What we checked: Formula selection, benchmark framing, example arithmetic, boundary statements, and source accessibility.
Purpose and scope: This page supports growth planning, pricing review, and customer-economics discussions. It is not a cohort warehouse and not a substitute for channel-level finance reporting.
How to use this review: Keep one customer definition, one time basis, and one formula choice consistent every time you run the model. That makes the trend line more useful than any isolated CLV reading.
Use Scenarios
Acquisition budget review
Use LTV with the Customer Acquisition Cost Calculator when you need to decide whether new spend is buying valuable customers or just buying faster churn.
Retention prioritization
Pressure-test whether LTV is mainly being constrained by short lifespan, weak repeat purchase, or high subscription churn before you redesign pricing or discounts.
Segment and plan design
Compare different customer types, plans, or channels with the same CLV method so margin and retention assumptions stay aligned during planning.
Formula Explanation
1) Revenue method
Revenue LTV = Average order value x Purchase frequency x Customer lifespan
This is the simplest view of lifetime value. It is useful when the business mainly needs a top-line estimate of what one customer relationship is worth over time.
2) Gross-profit method
Gross-profit LTV = Revenue LTV x Gross margin
This version is usually better for acquisition decisions because CAC has to be paid back with gross profit, not with revenue alone.
3) Subscription / churn method
Revenue LTV = Monthly revenue per customer / Monthly churn rate
If your dashboard shows retention instead of churn, convert it with `Monthly churn = 100% - Monthly retention`. When churn inputs are the real constraint, check the Churn Rate Calculator first so the lifetime assumption matches your retention reality.
4) Unit-economics view
LTV/CAC = Comparison LTV / Customer acquisition cost
The calculator uses gross-profit LTV for the ratio when margin is available. Without margin, it falls back to a revenue-based ratio, which is directionally useful but less conservative.
How to Read the Result
Benchmark ranges are planning context, not universal rules. Different contract length, margin profile, and customer mix can support very different CLV levels even inside the same industry.
Below benchmark range
Usually a sign that repeat purchase, retention, pricing, or margin needs work before the business assumes current acquisition cost is healthy.
Within benchmark range
A workable planning position, but still not enough by itself. You still need CAC, gross margin, and churn trend to decide whether the number supports more spend.
LTV/CAC below 3:1
The business may still grow, but the cushion is thin. One weak cohort, margin drop, or slower retention curve can turn a workable model into an expensive one quickly.
LTV/CAC at or above 3:1
A healthier operating range for many teams. Above 5:1 can be excellent, but it can also suggest the business has room to invest harder if retention and payback still look strong.
Example Cases
Case 1: DTC brand with workable repeat behavior
Inputs
- Average order value: $90
- Purchases per year: 4.2
- Customer lifespan: 2.4 years
- Gross margin: 58%
- CAC: $110
Computed Results
- Revenue lifetime value: $907.2
- LTV/CAC: 4.78:1
Interpretation
Revenue LTV looks healthy, but gross-profit room against CAC is still narrow enough that repeat purchase quality matters more than raw top-line value.
Decision Hint
Protect repeat rate and margin before assuming more paid social spend will stay efficient.
Case 2: PLG SaaS with healthy retention
Inputs
- Monthly revenue: $120
- Monthly retention: 95%
- Gross margin: 82%
- CAC: $420
Computed Results
- Gross-profit lifetime value: $1,968
- Revenue LTV: $2,400
- Average lifetime: 20 months
- LTV/CAC: 4.69:1
Interpretation
The modeled lifetime is being driven mainly by retention, so a small churn improvement is worth more than shaving a few dollars off acquisition.
Decision Hint
Prioritize activation, onboarding, and early expansion before opening new acquisition channels.
Case 3: Service business with premium acquisition
Inputs
- Average order value: $950
- Purchases per year: 4.0
- Customer lifespan: 2.1 years
- Gross margin: 64%
- CAC: $1,200
Computed Results
- Gross-profit lifetime value: $5,107.2
- Revenue LTV: $7,980
- LTV/CAC: 4.26:1
Interpretation
A premium CAC can still work when customer value is durable, but the business needs enough sales quality and retention discipline to justify the cost.
Decision Hint
Review qualification and proposal conversion before accepting even higher CAC as normal.
