What is Blended CAC?

How blended CAC actually works

Sum marketing costs for the month, count new customers from your store with repeat buyers filtered out, divide. Spend Rs 8,00,000, acquire 1,000 first-time buyers, and blended CAC is Rs 800 regardless of whether 300 of them arrived through a Google search you never paid a rupee for.

That inclusion is the whole point. Paid CAC tells you what ads cost. Blended CAC tells you what growth costs.

Plot it monthly. The direction of the line over six months says more than any single value on it.

Where teams get blended CAC wrong

Using it to judge channels. You cannot, because it has no channel dimension by construction, and slicing it produces something that is neither blended nor useful.

The more dangerous mistake is letting a strong organic base disguise weak paid performance, which happens constantly to brands with a loyal Delhi following who carry a blended CAC of Rs 600 while their Meta prospecting quietly buys customers at Rs 2,400 each. That works until you try to scale. Organic stays flat, the blended number climbs fast, and nobody saw it coming.

Watch the ratio between paid and blended CAC. Widening means paid is doing less work than the headline suggests.

What good looks like in India

Your LTV sets the target, not category convention. A twelve-month LTV of Rs 2,400 supports a blended CAC around Rs 800 at a 3 to 1 ratio, and whether Rs 800 is reachable depends entirely on your category, your creative and how crowded the auction has become.

One pattern holds across Indian D2C. Brands that invest early in owned channels see blended CAC fall while paid CAC rises, both at once, because media keeps getting dearer while the owned base absorbs more of the load. That divergence is the whole argument for distribution you do not rent.
