CTV budget planning requires more inputs than a simple CPM and total spend calculation. The variables that determine whether a CTV budget achieves its goals — reach, frequency, brand recall — include audience universe size, household coverage on target platforms, fill rate, flight duration, and the interaction between frequency caps and campaign pacing. Underestimate any one of these and the campaign either over-delivers to a small group of households or fails to build the frequency needed for brand impact. The CTV budget calculator models these interdependencies explicitly, so you can determine the budget needed to achieve a specific reach-and-frequency target rather than working backwards from an available spend figure.
Reach and frequency have a non-linear relationship in CTV. The first impression to each new household adds to your unique reach total. Each repeat impression to an already-reached household adds frequency without adding reach. As a campaign accumulates impressions, the ratio of reach-adding impressions to frequency-adding impressions shifts — early in a flight, most impressions expand reach; later in the flight, most impressions are repeat exposures. This diminishing reach curve is faster when targeting a narrow audience (small universe, fast saturation) and slower when targeting broad demographics (large universe, slow saturation). Budget allocation should account for this curve: spending the final 30% of a budget typically adds only 5–10% incremental unique reach.
Platform mix is a key budget allocation decision in CTV planning. Roku, Fire TV, Samsung TV Plus, Apple TV, and Android TV have meaningful household overlap — the same household may own multiple CTV devices. When building a media plan across multiple platforms, unified frequency management (via HouseholdID in LtvAdx) prevents the same household from accumulating ads across platforms beyond the intended cap. Without unified frequency management, a household that owns both a Roku and a Fire TV may receive 3× frequency on each platform — 6× total — which wastes budget on overexposed households and leaves other households unreached. Budget the frequency cap against total household exposures, not per-platform exposures.
Frequently asked questions
How much does a CTV advertising campaign cost?
A mid-size brand awareness CTV campaign (2M–5M impressions over 4 weeks) costs $60,000–$200,000 depending on CPM and platform mix. An entry-level campaign with limited targeting and open exchange CPMs ($18–$25) might cost $36,000 for 2M impressions. A targeted household-level campaign with audience data and premium CPMs ($40–$60) could cost $120,000 for the same impression volume. For most brands, $50,000–$150,000 is the budget range that delivers meaningful reach (500,000–1.5M unique households) and effective frequency (3–4× per household over a 4-week flight.
How do I estimate unique reach from a CTV budget?
Start with impressions: Budget ÷ CPM × 1,000. Divide impressions by your target average frequency (typically 3–5×) to get unique household impressions needed. Then apply platform household coverage: if Roku reaches 70% of your target demographic and you're buying Roku-only, multiply unique households by 0.70. If you're buying across multiple platforms, apply the combined deduplicated coverage (which requires HouseholdID for accurate measurement). The calculator automates this, but the key insight is that unique reach grows non-linearly — early impressions add more reach per dollar than later impressions.
What frequency should I target for a CTV brand awareness campaign?
Research on CTV ad effectiveness consistently points to 3–5 exposures per household as the optimal range for brand awareness and recall. Below 3×, most households won't form a durable memory of the brand. Above 5×, incremental effectiveness per impression drops sharply while creative fatigue increases. For direct-response CTV campaigns (driving app installs, site visits), slightly higher frequency (4–7×) can improve conversion rates because repeated exposure increases the probability the ad is seen at the moment of consideration. Cap frequency by flight period rather than by day — a 3× cap over 30 days is very different from a 3× cap in 7 days.
