עבריתWhat Is LTV (Customer Lifetime Value)?
LTV, or customer lifetime value, is the total revenue a business expects to earn from one customer over the full time that customer keeps buying.
LTV (customer lifetime value) is the total revenue, or in some models total profit, a business expects to earn from one customer over the entire time that customer keeps buying. The simple version: LTV = average order value x purchase frequency x customer lifespan. Marketers use it to figure out how much they can afford to spend acquiring a customer without losing money.
Why it's the number that should set your budget#
Without an LTV figure, customer acquisition cost is just a cost sitting in isolation. Once you know a customer is worth $180 over their lifetime, a $45 acquisition cost on a native campaign looks very different than it would if that same customer bought once for $50 and never came back. This is a big part of why subscription and repeat-purchase businesses can often outbid one-off ecommerce sellers for the same traffic on a native ad network: they're pricing the same click against a much bigger number.
Simple vs cohort LTV#
The basic formula (AOV x frequency x lifespan) is fast but rough. Cohort LTV tracks a specific group of customers acquired in the same period, say everyone who converted in March, and measures their actual cumulative spend at 30, 90, and 365 days out. Cohort LTV is slower to compute but far more honest, because it doesn't average in customers you haven't earned back yet.
| Approach | Speed | Accuracy | Best for |
|---|---|---|---|
| Simple/blended LTV | Fast | Rough | Early-stage, low volume |
| Cohort LTV | Slow, needs history | High | Scaling, budget-setting |
| Predictive LTV (modeled) | Fast, needs data science | Medium to high | Large subscription businesses |
LTV in native and affiliate media buying#
Affiliate offers usually pay a flat CPA (Cost Per Acquisition) or EPC (Earnings Per Click) per conversion, so LTV mostly lives with the advertiser rather than the affiliate, unless the offer includes rebill or recurring commission structures common in nutra and subscription verticals. If you're buying media for your own brand instead of running an affiliate offer, LTV should directly inform your max bid and your ROAS target.
A brand with a 90-day LTV of $60 and a brand with a 90-day LTV of $200 selling a similar-looking product can sustain very different CPCs on the same placement. That's one reason the same vertical can show wildly different bid ranges when you check live spend across a network's index.
Where LTV breaks down#
LTV models built on early data tend to overstate lifespan, because customers who churn late simply haven't churned yet at the point you calculate it. Businesses that lean too hard on an optimistic LTV number often end up bidding above their real breakeven and only find out months later, once blended marketing efficiency across the whole account starts sliding. Watching media buying costs alongside LTV, rather than after the fact, is what keeps that gap from opening in the first place.
How OpenAdLibrary helps#
Before you commit a budget built around an assumed LTV, it helps to see how competitors in your vertical are actually behaving. OpenAdLibrary's ad intelligence tools show how long a competitor's creative has been running across networks, a rough proxy for profitability, which is a useful sanity check against your own LTV-driven bid math.
