Display advertising costs in 2026 are no longer moving as a single market. According to 2026 programmatic advertising data, the average CPM on the Google Display Network sits at $3.12, while private marketplace (PMP) deals — curated, brand-safe inventory sold directly rather than through open auction — average $8.20. Connected TV (CTV) display inventory runs even higher, averaging $24.50 per thousand impressions.

A widening gap, not just a range

This isn’t simply „display ads cost between $3 and $25“ — it’s a genuine bifurcation. The gap between commodity open-exchange placements and curated, brand-safe inventory has widened by more than 60% since 2024, and overall CPM growth ran about 12% year-over-year from 2025 to 2026. Advertisers are increasingly paying a real premium for guaranteed placement quality and brand safety, rather than accepting whatever inventory an open auction happens to serve.

Why this matters for how you plan a budget

Treating „display CPM“ as one number when budgeting a campaign is a common mistake, given how differently these tiers price. A campaign planned around open-exchange programmatic rates (as low as $2.80 on average) will blow through budget fast if the media buy actually lands on premium PMP or CTV inventory instead — or conversely, a budget set for premium placements will be substantially underspent if it ends up buying remnant inventory. Knowing which tier you’re actually buying into, before setting a budget, avoids both problems.

Run the numbers for your own campaign

Whichever tier you’re planning for, the underlying math — spend versus impressions versus CPM — is the same. Our CPM calculator lets you calculate your actual cost per thousand impressions from a real campaign, or work backward from a target CPM to estimate total cost before you commit budget.
