What are LTV and CAC in dating?

LTV and CAC are the two numbers at the heart of every dating business model, and getting them honest is the difference between scaling profitably and burning money fast. Both have dating-specific traps that catch operators who borrow definitions from general software.

LTV: lifetime value

LTV, or customer lifetime value, is the total gross revenue you expect from a paying user before they cancel. At its simplest it is average revenue per paying user multiplied by the average number of months a payer stays. The dating trap is the months: paying lifetimes are short because a product that works removes the reason to keep paying, so monthly churn runs 15 to 25 percent and average lifetimes are measured in months, not years. That compresses LTV by an order of magnitude compared with a typical software model. And LTV is gross, so refunds, chargebacks, app store commissions, and payment fees all sit between it and your bank account.

CAC: customer acquisition cost

CAC is the blended cost to acquire one paying subscriber, including paid media, attribution, and incentives. The dating trap is that you are not really buying a user, you are buying one side of a marketplace that only works in balance. Acquire the abundant side into a market short on the other and your new users churn fast, so your nominal CAC looks fine while your real cost, to acquire a user who actually stays, is far higher. Honest CAC in dating is segmented by side of the marketplace and by geography, not blended.

The ratio that matters

Divide LTV by CAC and you get the multiple of value created for every dollar of acquisition. In paid dating the working floor is around three to one, but it must be a net floor, after refunds, fees, and disputes, not a gross one. Alongside the ratio, CAC payback, the number of months to earn back acquisition cost, matters just as much, because cash, not ratios, is what runs out. Operators target payback under three months. A healthy long-term ratio with slow payback can still sink a business that runs out of runway first.

How to use them

Read both by cohort, not as blended averages, because a blended number hides the moment the model turns. Track ARPPU and conversion separately so you understand what drives LTV, and watch marketplace balance because it drives the real CAC. If the math works net, scale with confidence; if it does not, fix churn, conversion, or balance before spending. The unit economics calculator in our guide lets you pressure-test all of this with your own numbers.
