How Much Does AI Video Generation Cost Per Video?

Why nobody can quote you a single price per video

A plan buys you a pool of credits. Each generation spends some of them, and the price of a generation changes with the model you pick, the length of the clip, the resolution and extra features like upscaling. Two users on the same plan can pay completely different amounts per finished video: one writes tight prompts and uses most generations, the other experiments loosely and discards half of everything they make.

This is deliberate pricing design, explained in AI video credits explained: metering by credits lets a vendor charge for the actual computing your requests use. For you, it means the plan price is only the first of three numbers that decide your real cost.

The three numbers that decide your real cost

First, the plan price — what you pay per month whether you use the credits or not. Second, the credit cost per generation for the model and settings you actually use: premium models, longer clips and higher resolutions spend credits faster on every platform. Third, your success rate — the share of generations that survive into the finished video. If one in three generations is usable, your effective cost per usable clip is roughly three times the per-generation cost, because the rejected two still burned credits.

That third number is the one beginners miss, and it improves with skill. Better prompts, one action per clip and reusing good generations as starting frames all raise your success rate, which is the cheapest price cut available. Our guide on how to write a good text-to-video prompt is effectively a cost-cutting guide for this reason.

• Plan price: what the subscription costs each month
• Credits per generation: set by model, length and resolution
• Success rate: the share of generations you actually keep
• Real cost per finished video = plan spend ÷ finished videos that month

What entry plans actually cost in our listings

Prices below are the entry paid plans exactly as stated on our listings, checked against the vendors' official pages. Among pure generators, Kling AI starts from around $7–$10 a month, Pika from $8 a month billed annually, and Runway from $12 a month billed annually. Luma Dream Machine sits higher, from $25 a month billed annually, and has no free plan.

Tools that assemble whole videos price differently: InVideo AI starts from $10 a month billed annually, Synthesia from $14 a month billed annually, OpusClip from $15 a month, VEED from $18 a month per user and HeyGen from $24 a month billed annually for its Creator plan. Treat every figure as a starting point — plans change, and each listing shows its current entry price and what the credits or minutes buy.

The costs hiding behind the headline price

Retries are the biggest hidden cost, covered above. Next come the extras around generation: upscaling a clip to HD or 4K with a tool from the video enhancer category, generating a voiceover with a voice tool, or buying stock footage for the shots AI does badly. None of these is compulsory, but a polished workflow often includes one or two of them, and they belong in your per-video maths.

Billing style quietly matters too. Many entry prices in our listings are quoted per month but billed annually — Runway's $12, Pika's $8 and HeyGen's $24 are all annual-billing figures. Paying month to month usually costs more per month. When you compare two tools, compare like with like: same billing period, same resolution, same clip length.

Finally, count your own time honestly in any comparison with filming. Generation is fast, but choosing, trimming and assembling are not: an evening of editing is a real input even when no invoice records it. Creators who publish weekly treat the workflow itself — saved prompts, editor presets, a fixed export setting — as part of the price, and invest in it once precisely because it lowers the cost of every video that follows.

What a free plan really costs: nothing, with limits

Free plans cost $0 and are the right way to test a workflow. What they limit is output: free generations on Kling AI carry a watermark, free exports from InVideo AI carry a watermark, and Synthesia's free Basic plan is watermarked and share-link only. Pika is the notable exception on marks — no watermark on any plan, free included — though its free plan carries no commercial licence, which is a different limit entirely.

So a free plan's real price is paid in restrictions: watermarks, lower resolution, fewer credits and, often, no right to use the output commercially. Our roundup of the best free AI video generators lays out each free plan's limits side by side, and the watermark guide explains why the limits exist.

How to work out your own cost per video

Do it empirically. Spend one month on the cheapest plan that fits, log every finished video you publish, and divide. That single number — your cost per finished video, with your prompts and your success rate — is worth more than any comparison table, ours included. If the number is too high, the fix is usually a higher success rate or a plan whose credits match the model you actually use, not a cheaper headline price.

To model it before spending, use our free cost calculator: enter how many videos you plan to make and it converts plan credits into a per-video cost using the same listing prices. Then check the top tools ranking to see which tools give you the most finished video for that budget.

One last discipline: re-run the calculation whenever a tool changes its prices or credit rates, which happens often in this market. A per-video cost computed in January can be plain wrong by spring. Every listing on this site shows when its facts were last checked against the vendor's official pages, so you can see at a glance when the inputs to your own maths may have moved.

A worked example: same plan, two very different costs

Take a purely illustrative example — the numbers are invented to show the shape, not taken from any tool. Suppose an entry plan costs $12 a month and, at your usual settings, covers roughly 120 generations. Creator A writes tight prompts, drafts at low settings, and keeps one generation in two: she ends with about 60 usable clips and cuts them into 8 published videos, a cost of $1.50 per finished video. Creator B tests every idea on the flagship model at full length and keeps one generation in four: he gets about 30 usable clips and publishes 4 videos, a cost of $3 per finished video — exactly double, on the identical subscription.

The lesson is that the plan price is the smallest variable in the equation. Success rate and settings discipline move your real price more than any discount or plan tier, which is why this site converts plans into per-video costs instead of ranking them by sticker price. It is also why your first month on any tool should be treated as measurement: log the finished videos, divide the bill, and only then decide what size of plan your workflow honestly needs.
