Operator-grade cost math for AI video in 2026. Real per-second and per-finished-video numbers across Runway, Kling, Pika, Sora, Luma, HeyGen, and ElevenLabs, the revision multiplier that doubles sticker price, the hidden costs nobody quotes, and the honest break-even against hiring a video editor — by output volume.
AI video per-second cost in 2026 ranges roughly $0.04-0.75 depending on tool and quality tier — Kling and Runway Gen-4 Turbo at the bottom (~$0.04-0.10/sec), Veo on Vertex at the top (~$0.35-0.75/sec). But the number that drives your budget is cost per FINISHED video, not per generated second, and that runs $5-50 for a 30-second short once you fold in the revision tax (1.4-1.8 generations per usable clip), source-asset prep, color matching, audio cleanup, captions, and human review. Break-even versus a part-time editor lands around 5 videos/month for solo creators and 30-50/month for brand-strict teams. Sticker price is the smallest part of the real bill.
AI video pricing is more honest than most marketing pages suggest — and less dramatic than the "$0.06 per second!" headlines imply once you account for everything those headlines leave out. The per-second sticker is real, but it describes a single successful generation, not a finished, on-brand, captioned, color-matched clip you would actually publish. The gap between those two numbers is where every budget surprise lives.
This is the operator-grade math. We start from the verified 2026 per-second rates, apply the revision multiplier that every production team eventually discovers, walk the hidden costs nobody quotes you, then run the break-even against hiring an editor at three output volumes. The bottom line up front: AI video is dramatically cheaper than human production above a handful of videos a month, but the real cost is 3-4x the advertised compute cost, and the break-even depends almost entirely on your volume and your brand-consistency bar. Pairs with [text-to-video-tools-2026](/ai-video-generation/text-to-video-tools-2026) for the model-by-model quality read, [avatar-video-comparison](/ai-video-generation/avatar-video-comparison) for the avatar-engine economics, and [pricing](/pricing) for how orchestration collapses the stack into one credit line.
Every AI video tool quotes you a per-second or per-credit price. That number answers one question: what does one successful generation cost? It does not answer the question your budget actually asks: what does one finished, publishable clip cost? Those diverge for three reasons — you regenerate to land the shot, you spend on inputs the generation does not include (script, voice, music, B-roll), and you spend operator time assembling and cleaning the output. A 5-second clip with a $0.40 sticker can carry a $3-5 fully-loaded cost by the time it is in the feed.
The rest of this spoke walks the layers of that gap in order: the per-second floor, the revision multiplier on top of it, the hidden costs around it, and finally the break-even that all of it rolls up into. Hold both numbers in your head as you read — the per-second sticker is the floor, never the bill.
The per-second floor at 1080p on each tool's standard paid tier, derived from credit allotment divided by typical consumption. These are nominal — the cost of one clean generation, before the revision tax. Cross-referenced against the live pricing pulled for [text-to-video-tools-2026](/ai-video-generation/text-to-video-tools-2026).
| Tool | Plan used for the math | Approx cost per 1080p second | What you get |
|---|---|---|---|
| Runway Gen-4 Turbo | Standard $12 / Pro $28 | $0.04-0.10 | Cheapest Western model at the production bar; filmic look |
| Kling 2.0 | Standard ~$7.99 / Pro tier | $0.05-0.15 | Motion fluidity; 10s base clips; strongest value for action |
| Pika 2.x | Pika ~$8/mo entry | $0.08-0.20 | Stylized effects; fast iteration; 5s clips |
| Sora 2 | OpenAI premium tier (above Kling/Pika) | Premium band | Narrative coherence + audio-in-frame; priced as a premium model |
| Luma Dream Machine | Plus $30 / Pro $90 | $0.15-0.40 | Real-time previews; clean reference-image lock |
| Veo 3 (Vertex API) | Pay-as-you-go | $0.35-0.75 | Most expensive per second; physics + native synced audio |
| HeyGen (avatar) | Creator $29 | ~$0.04/sec equivalent | ~30 min Avatar IV output; talking-head, not text-to-video |
| ElevenLabs (voice) | Creator $22 (Starter $6) | ~$0.02/sec equivalent | AI narration; the cheapest layer in the whole stack |
Two structural reads. First, the spread between cheapest and most expensive text-to-video is roughly 4-7x for output most viewers would call "similar 1080p" — the premium tiers (Veo, Sora, Luma) earn it on physics, audio, narrative, and character lock, not on raw resolution. Second, the avatar and voice layers are an order of magnitude cheaper per finished second than generative text-to-video, which is why faceless and avatar workflows carry such low marginal cost. See [faceless-video-creation](/ai-video-generation/faceless-video-creation) for the per-video math on those patterns.
No AI video clip lands on the first try. Prompt adherence across every 2026 model misses roughly one generation in four at the median, so you regenerate — for the shot, for the color, for the framing. Across the leading text-to-video models, plan on 1.4-1.8 generations per finished clip; for brand-strict work or stylized shots that don't resolve cleanly, 2-4 is common. That multiplier sits directly on top of the per-second floor.
| Clip | Nominal cost | Revisions to land it | Effective cost | Multiplier |
|---|---|---|---|---|
| 5s Pika clip | $0.40 | 2-4 attempts | $0.80-1.60 | 2-4x |
| 8s Runway Gen-4 Turbo B-roll | $0.32-0.80 | 1.4-1.8 median | $0.45-1.45 | ~1.6x |
| 10s Kling action shot | $0.50-1.50 | 1.5-2 attempts | $0.75-3.00 | ~1.7x |
| 8s Veo product shot (Vertex) | $2.80-6.00 | 1.3-1.6 (high adherence) | $3.65-9.60 | ~1.5x |
| 30s HeyGen avatar segment | ~$1.20 | 1-2 (script-driven, predictable) | $1.20-2.40 | ~1.5x |
The revision tax is the cost you can see. The hidden costs are the ones that don't show up on any pricing page because they are inputs and labor, not generations. At production volume these routinely match or exceed the generation spend itself.
Sum the hidden layer and the rule of thumb holds across nearly every workflow we have modeled: the real per-video cost is 3-4x the advertised compute cost. A "$1 of credits" short is a $3-4 short once prep, matching, cleanup, captions, and review are honest.
Rolling the floor, the revision tax, and the hidden costs into a single per-finished-video number for a 30-second short — the unit most creators and marketers actually ship.
| Format | Compute (post-revision) | Tools amortized | Operator time | Fully-loaded per video |
|---|---|---|---|---|
| Slideshow + AI narration (stock images) | $0.20-0.80 | $6-22/mo voice | 8-15 min | $2-6 |
| AI-narrator + stock B-roll (faceless) | $0.50-2.00 | $30-80/mo | 15-25 min | $5-15 |
| Avatar + B-roll (HeyGen segment) | $1.50-4.00 | $29-80/mo | 25-40 min | $8-25 |
| Generative-video heavy (Runway/Pika shots) | $4-25 | $70-150/mo | 60-180 min | $20-50 |
The takeaway: per-finished-video cost is dominated by format choice and operator time, not by which generative model you picked. Switching from Pika to Kling saves cents per clip; switching from a generative-heavy pattern to an AI-narrator-stock pattern saves dollars and hours per video. Optimize the workflow before you optimize the model.
The question every operator actually wants answered. Here is the monthly cost of an AI workflow producing 30-second shorts at 30 videos/month, against the cost of a part-time editor producing the same.
| Line item | AI workflow (30 videos/mo) | Part-time editor (30 videos/mo) |
|---|---|---|
| Tools / subscriptions | $80-150/mo | N/A |
| Compute (post-revision) | $30-90/mo | N/A |
| Labor | 7.5-15 operator hrs (opportunity cost) | 30-90 hrs at $25-75/hr |
| Cash cost | $110-240/mo | $750-6,750/mo |
| Quality ceiling | High at volume; brand-strict needs review | Highest on continuity / brand match |
The break-even points, distilled: for a solo creator, AI wins at essentially any volume above ~5 videos/month — below that, an editor's time on a tiny batch is competitive with AI's total loaded cost including revisions. For a team with a strict brand-consistency bar, the human-editor option stays competitive up to ~30-50 videos/month, because the review-and-rework time on AI output at that bar erodes the cash advantage. Above ~50 videos/month, AI dominates regardless — no editor produces that volume at competitive cost.
The honest limits matter as much as the savings, because believing AI is cheaper everywhere is how teams overspend on the wrong tool for a job a human still owns.
The per-tool math above assumes you hold every subscription yourself — a voice tool, a B-roll source, a clipper, an avatar engine, a captioner — and pay each separately while absorbing the operator time of moving assets between them. That stack is where the hidden costs concentrate: five logins, five billing lines, and the switching tax of assembling output by hand.
An orchestration layer collapses that into one credit line. Kompozy routes the underlying providers per format and meters everything as credits — text at 3, image at 8, blog at 12, a clipped short at 14, an avatar short at 106, an AI-generated short at 214 — so Creator ($49/mo, 2,500 credits) or Pro ($299/mo, 18,000 credits) buys a predictable monthly output budget instead of a pile of separate per-second bills you reconcile at month-end. The Founding tier ($39 BYO-key) routes the same orchestration against your own provider keys. The cost story changes from "what does each second cost across five tools" to "how many finished outputs does this credit pool buy" — which is the number that actually maps to your content calendar. See [pricing](/pricing) for the full per-format credit table and [content-repurposing](/repurpose) for how one source fans into many outputs off one credit pool.
Per-second AI video cost has fallen roughly 60% per year from 2024 to 2026 as models and compute got more efficient, and another 40-50% drop in 2027 looks locked in based on shipped roadmaps and funding patterns. The practical effect is not that the cheapest tool gets cheaper — it is that the break-even floor keeps dropping, so AI wins at lower and lower output volumes each year. The revision tax shrinks too as prompt adherence improves, which compresses the gap between sticker price and finished-video cost.
What does not fall on that curve: the hidden costs that are labor, not compute. Source-asset prep, brand review, and editorial judgment stay roughly fixed because they are human time, and human time does not ride Moore's law. As compute approaches free, those become the entire cost of an AI video — which is exactly why the workflow decision (format, operator time) outweighs the model decision (which provider) and will outweigh it more every year.
For 5+ short-form videos per month: yes, dramatically — an AI workflow runs $110-240/mo all-in versus $750-6,750/mo for a part-time editor at the same volume. For 1-2 high-budget videos: not necessarily, because an editor's time on a tiny batch is competitive with AI's total loaded cost once you fold in revisions and review.
For a 30-second short: $2-6 for slideshow + AI narration, $5-15 for AI-narrator + stock B-roll, $8-25 for avatar + B-roll, and $20-50 for generative-video-heavy formats. These are fully-loaded numbers — the advertised compute cost is typically 3-4x smaller than the real per-video cost once revisions, prep, color matching, audio cleanup, captions, and review are counted.
Three reasons stack on top of the sticker. The revision tax (1.4-1.8 generations per usable clip, 2-4x for stylized or brand-strict shots), the hidden inputs (script, voice, music, reference images, captions), and operator time (prep, color matching, audio cleanup, review). The sticker describes one successful generation; your bill describes a finished, publishable clip.
Per second of text-to-video at the production-quality bar: Runway Gen-4 Turbo (~$0.04-0.10/sec) and Kling 2.0 (~$0.05-0.15/sec). Per second of avatar output: HeyGen Creator at ~$0.04/sec. Per second of AI voice: ElevenLabs at ~$0.02/sec. But the cheapest finished video comes from the format choice (slideshow or AI-narrator-stock), not the cheapest model.
Roughly $80-150 in tools plus post-revision compute. For faceless 30-second shorts at $1-3 loaded compute each, that is ~$1,080-3,150/month all-in. Human production of 1,000 comparable videos would run well into five figures monthly, so AI dominates decisively above ~100 videos/month.
For a solo creator: about 5 finished videos/month is the crossover — below that an editor on a small batch is competitive. For a brand-strict team, the editor stays competitive up to ~30-50/month because review-and-rework time erodes the cash advantage at a high quality bar. Above ~50/month, AI wins in every scenario we model.
It changes the cost structure more than the headline number. Instead of five separate per-second bills plus the operator time of moving assets between tools, you get one credit pool (Creator $49/mo for 2,500 credits, Pro $299/mo for 18,000) metered per format — a clipped short at 14 credits, an avatar short at 106, an AI-generated short at 214. The win is predictability and reclaimed operator time, which is the largest hidden cost in the whole stack.
Yes — per-second cost has fallen roughly 60% per year since 2024, and another 40-50% drop in 2027 looks locked in. But the labor-side hidden costs (script prep, brand review, editorial judgment) do not fall on that curve because they are human time. As compute approaches free, those become the entire cost of an AI video, which is why the workflow decision outweighs the model decision and will more every year.
