Customer Lifetime Value (LTV) measures the total gross profit expected from a single customer over their entire relationship with your company. This calculator estimates LTV using revenue, purchase frequency, churn rate, and margin assumptions to help SaaS and B2B companies evaluate whether their acquisition spending is sustainable.
Customer Lifetime Value represents the total gross profit a customer generates across their entire relationship with your company. It is the numerator in every acquisition efficiency calculation and the single best predictor of sustainable growth. This calculator supports multiple LTV methodologies — from basic revenue multiplication through churn-adjusted, margin-weighted, and discounted cash flow models — because the right approach depends on your business maturity and data availability. SaaS finance teams, investor-facing founders, and customer success leaders use LTV to set acquisition budget ceilings, identify high-value customer segments, and quantify the revenue impact of retention improvements. An increase of just a few percentage points in retention rate can double LTV over a multi-year horizon due to compounding effects.

Interpreting Your Customer Lifetime Value
LTV is only meaningful in the context of what it costs to acquire and serve that customer. An LTV of $50,000 sounds impressive until you learn CAC is $40,000 and gross margin is 60 percent — at which point the true economic value per customer is only $30,000 minus $40,000, a loss. Always evaluate LTV in conjunction with CAC and gross margin. LTV that falls below the industry median usually points to one of three issues: high churn (customers leave too early for revenue to compound), low expansion revenue (no upsell or cross-sell motion), or declining ARPU (pricing does not grow with usage). The fastest path to LTV improvement is churn reduction — a 5 percent reduction in annual churn has a larger LTV impact than a 10 percent increase in ARPU because it extends the compounding window. For subscription businesses, segment LTV by acquisition cohort and channel: if LTV varies significantly by source, your CAC targets should vary accordingly rather than using a single blended figure.
Customer Lifetime Value by Business Model
| Segment | Low | Median | High |
|---|---|---|---|
| B2B SaaS (SMB) | $3,500 | $8,000 | $18,000 |
| B2B SaaS (Mid-Market) | $25,000 | $65,000 | $150,000 |
| Professional Services | $15,000 | $42,000 | $120,000 |
| Digital Agencies | $12,000 | $35,000 | $85,000 |
What Is Customer Lifetime Value?
Customer Lifetime Value is the predicted net profit attributed to the entire future relationship with a customer. It accounts for repeat purchases, contract renewals, expansion revenue, and gross margin over an estimated customer lifespan. LTV is the numerator in every acquisition efficiency formula and the foundation of sustainable growth modeling.
How to Calculate LTV for B2B Companies
The simplest LTV formula multiplies average revenue per account by customer lifespan in years. For greater accuracy, apply gross margin percentage and adjust for churn: LTV equals ARPU multiplied by gross margin divided by monthly churn rate. Advanced models add expansion revenue and apply a discount rate to account for the time value of future cash flows. Most B2B companies should use the gross-margin-adjusted model at minimum.
What Is a Good LTV Benchmark?
Healthy LTV varies dramatically by segment. SMB SaaS companies with $500 monthly ARPU and 5 percent monthly churn typically see LTV around $6,000 to $10,000. Mid-market SaaS with $5,000 monthly ARPU and 1.5 percent monthly churn can reach $200,000 or higher. The benchmark that matters most is LTV relative to CAC: a ratio of 3:1 or better is the standard threshold for scalable growth.
How to Improve Customer Lifetime Value
The three highest-leverage improvements are reducing churn (extends the compounding window), increasing expansion revenue through upsells and cross-sells (raises ARPU without new acquisition cost), and improving onboarding to reduce early-stage cancellations (where the steepest churn curve occurs). A 5 percent reduction in annual churn typically produces a larger LTV increase than a 10 percent increase in ARPU because it multiplies across all future periods.
Common Measurement Mistakes
Common Measurement Mistakes
- •Using revenue instead of gross profit — LTV should reflect margin, not top-line revenue, because cost of goods sold varies significantly across customer segments and erodes the actual value each customer generates.
- •Ignoring cohort differences — blending all customers into a single LTV figure hides the fact that different acquisition channels, contract sizes, and customer segments have dramatically different retention curves and lifetime values.
- •Assuming constant churn — early-stage churn (first 90 days) is typically 2-3x higher than steady-state churn, so models that use a single churn rate overestimate LTV for new cohorts.
- •Excluding expansion and contraction — models that only count initial contract value miss the 15-30 percent of revenue that comes from upsells, and ignore the downgrade revenue that offsets it.
- •Not discounting future revenue — a dollar received three years from now is worth less than a dollar today, especially for companies with cost of capital above 10 percent.
When This Metric Breaks Down
When This Metric Breaks Down
LTV calculations break down for companies with fewer than 12 months of retention data, where churn estimates are unreliable projections rather than observed behavior. The metric also loses meaning for project-based businesses with no recurring revenue component, and for companies undergoing rapid pricing changes where historical ARPU does not predict future ARPU. In hypergrowth environments where the customer base doubles annually, cohort-level LTV is essential because blended figures are dominated by immature cohorts that have not yet revealed their true retention behavior.

- What is a good LTV for B2B companies?
- A good LTV varies by industry. For B2B SaaS, the median LTV is $24,000.00, with top performers achieving $45,000.00 or higher.
- How does churn affect LTV?
- Churn directly reduces customer lifespan, which is a multiplier in the LTV formula. Reducing churn by 1% can significantly increase LTV.
- Why use risk-adjusted LTV?
- Risk-adjusted LTV accounts for uncertainty in future revenue, providing a more conservative and reliable figure for business planning and CAC budgeting.

Calculation Methodology
The basic LTV model multiplies average revenue per customer by average customer lifespan. Advanced models layer gross margin adjustment, churn-based lifespan estimation (1 / churn rate), net expansion revenue, and time-value discounting. All models use annual or monthly periods depending on the billing cycle, and benchmarks reflect aggregated 2026 B2B industry data.
