What is Customer Lifetime Value (LTV)?
Also known as: LTV, CLV, Customer LTV
What is customer lifetime value (LTV)?
Customer lifetime value (LTV) is the total profit a single customer generates from acquisition to churn. The classic Harvard Business Review research on loyalty economics found that a 5 percent lift in retention can raise profits 25 to 95 percent (Reichheld and Sasser, HBR). LTV captures that compounding effect in one number.
LTV sets the ceiling on what you can spend to acquire a customer. Get LTV right and every CAC ceiling, bid cap, and payback target falls into place. Get it wrong and paid acquisition either stalls or burns cash.
Two flavors matter. Revenue LTV uses top-line dollars. Margin LTV uses gross profit. Boards run on margin LTV.
LTV formulas (simple, contribution-margin, predictive)
Three formulas. Each one trades simplicity for accuracy.
| Formula | When to use | Example |
|---|---|---|
| Simple LTV = ARPU / churn rate | Month-one model, no cohort data yet | $99 ARPU / 4% monthly churn = $2,475 |
| Contribution-margin LTV = (ARPU x gross margin) / churn rate | You know unit economics | ($99 x 0.75) / 0.04 = $1,856 |
| Predictive LTV = sum of discounted cash flows from a cohort retention curve | You have 12+ months of cohort data | Built from cohort actuals, discounted at 10% |
The simple formula gets you started. It overstates LTV because it assumes 100 percent margin and a flat churn curve. Real churn is front-loaded. Real margins are below 100 percent.
Contribution-margin LTV is the working number for most performance marketing decisions. It nets out cost of goods, payment fees, and support cost before deciding what a click is worth.
Predictive LTV is what finance teams report. It uses cohort retention curves and a discount rate, per ProfitWell's subscription metrics framework. Most SaaS teams cap projected lifespan at 36 to 60 months to keep the number honest.
LTV by industry (benchmarks)
LTV varies wildly by business model, contract length, and price point. The numbers below are directional, not gospel.
| Segment | Typical 12-month LTV | Source |
|---|---|---|
| SMB SaaS ($50-$200 ARPU) | $600 to $2,400 | Recurly Research 2024 |
| Mid-market B2B SaaS | $5,000 to $25,000 | ProfitWell 2024 |
| Enterprise SaaS (annual contracts) | $40,000 to $200,000+ | ProfitWell 2024 |
| Ecommerce (repeat purchase) | $150 to $400 | Shopify Commerce 2023 |
| Subscription ecommerce (DTC) | $200 to $600 | Recurly Research 2024 |
| Mobile app subscriptions | $30 to $90 (Year 1) | RevenueCat 2024 |

Two rules of thumb hold across segments. Annual plans show 30 to 50 percent higher LTV than monthly plans. Sales-led businesses show higher LTV than self-serve at the same ARPU because churn is lower.
LTV-to-CAC ratio: the most important SaaS metric
The single number that decides whether a business compounds is LTV divided by customer acquisition cost. Per Bain & Company's loyalty economics work, top-quartile subscription businesses run LTV-to-CAC above 3:1 with payback under 12 months.
| LTV : CAC | What it means |
|---|---|
| Below 1:1 | You lose money on every customer. Stop spending. |
| 1:1 to 3:1 | Acceptable for early stage. Margin is thin. |
| 3:1 | Healthy. Standard SaaS benchmark. |
| Above 5:1 | Likely under-investing in growth. Spend more. |
The ratio matters more than either number alone. A $5,000 LTV is great until you learn the CAC is $4,000. A $400 LTV is fine if the CAC is $90.
Payback period sits next to the ratio. A 3:1 LTV-to-CAC with a 36-month payback breaks cash flow. The same ratio with a 9-month payback is a printing press.
How to grow LTV (retention, upsell, cross-sell, pricing)
Four levers move LTV. They compound.
Retention
Cutting churn is the highest-impact move. LTV is roughly ARPU divided by churn. Halve the churn rate and LTV doubles. The classic Bain finding still holds: a 5 percent retention lift can raise profits 25 to 95 percent (Bain & Company). Onboarding fixes, dunning, and annual-plan defaults move the number fastest.
Upsell and expansion
Existing customers convert at 60 to 70 percent on upsells, per ProfitWell's expansion revenue research, versus 5 to 20 percent on new prospects. Plan tiers, seat expansion, and usage-based add-ons all show up in net revenue retention. Top-quartile SaaS hits NRR above 120 percent.
Cross-sell
Adjacent products extend the relationship. A second product in the cart raises retention more than discounting the first one. The data point most teams miss: a customer who owns two products churns at roughly half the rate of a single-product customer.
Pricing
Pricing is the fastest LTV lever and the most under-used. A 10 percent price increase flows almost entirely to gross margin. Annual plans, usage tiers, and value-metric repricing all raise ARPU without proportionally raising churn.
Real-world example with numbers
A B2B SaaS sells a $99 per month plan with 75 percent gross margin and 4 percent monthly churn.
Simple LTV = $99 / 0.04 = $2,475
Contribution-margin LTV = ($99 x 0.75) / 0.04 = $1,856Blended CAC across paid channels is $620. LTV-to-CAC ratio:
$1,856 / $620 = 2.99Right at the 3:1 benchmark. Healthy, not exceptional.
The team runs three plays over the next two quarters:
| Lever | Move | Effect |
|---|---|---|
| Retention | Annual-plan default at checkout | Monthly churn drops 4% to 2.8% |
| Upsell | Seat expansion email sequence | ARPU rises $99 to $112 |
| Pricing | New plan tier at $149 | 18% of new customers pick the higher tier |
Recalculated LTV:
New blended ARPU = $118
New monthly churn = 2.8%
Contribution-margin LTV = ($118 x 0.75) / 0.028 = $3,161LTV climbs 70 percent. CAC stays at $620. The new ratio sits at 5.1:1, which means the team can either pay more per click to scale or hold spend and bank the margin.
LTV in performance marketing
Most ad accounts treat LTV as a finance number. Performance teams that wire it into the ad stack pull ahead.
Three places LTV feeds the media buy:
- CAC ceilings. Bid caps and target CPA get derived from cohort LTV, not first-purchase margin. Refresh every quarter as churn shifts.
- High-LTV lookalikes. Export the top 10 percent of customers by 12-month LTV. Hand the list to Meta and Google as a seed audience. The lookalike pulls prospects who match the value profile, not just the demographic.
- Creative and offer angles. The features high-LTV customers use most become the headline angles for prospecting creative. The offers that lifted retention become the win-back angles for retargeting.
In a connected platform like Coinis, cohort LTV exports plug straight into audience definition and creative generation. The number stops sitting in a spreadsheet. It starts buying media at the right ceiling.

Frequently asked questions
What is the difference between LTV and CLV?
Nothing. LTV and CLV are the same metric. Customer lifetime value gets shortened to either acronym depending on the team. Finance and SaaS shops favor LTV. Ecommerce and CRM tools tend to use CLV. Pick one and stay consistent across reports.
How is LTV different from revenue per customer?
Revenue per customer is a top-line number for one period. LTV is a profit number across the full customer relationship. The strongest version of LTV uses gross margin, not revenue, and weighs in churn. Revenue LTV inflates the ceiling you can pay on acquisition.
What is a good LTV-to-CAC ratio?
Three to one. An LTV three times your customer acquisition cost is the standard benchmark for healthy SaaS, per Bain & Company's customer economics research. Below 1:1 you lose money on every customer. Above 5:1 you are likely under-investing in growth.
How do I calculate LTV without years of data?
Use the simple formula. ARPU divided by monthly churn gives a workable LTV in month one. As cohort data builds, switch to the contribution-margin or predictive version. Per ProfitWell's subscription benchmarks, most teams refresh LTV quarterly once cohorts stabilize.
Does LTV apply to ecommerce too?
Yes. Repeat-purchase ecommerce uses LTV the same way SaaS does. Average order value times purchase frequency times gross margin times customer lifespan. Per Shopify's commerce data, repeat customers drive roughly 40 percent of ecommerce revenue despite being a smaller share of orders.
