How is AI video cost calculated?

Most platforms bill per second of generated video, scaled by resolution and model tier, then convert credits to USD. This tool multiplies your duration, resolution multiplier, and clip count for each platform's published rate.

Are these prices exact?

No — they are editable estimates based on published list and credit prices, which change often. Confirm the current rate inside each provider's dashboard before budgeting.

Which AI video tool is cheapest?

It depends on length and resolution. Shorter 720p clips are cheapest on Pika and Haiper, while longer high-fidelity clips often favour Kling or Luma. The comparison shows the winner for your exact specs.

Does generation cost more at higher resolution?

Yes. 1080p typically costs roughly 1.5–2× the 720p rate, and 4K (where offered) more again, because more frames and pixels are rendered.

Video Generation Credit & Cost Calculator

Compare AI video generation costs

Pricing for AI video tools is confusing because each one uses different credits, tiers, and per-second rates. This calculator normalises them: enter your clip length, resolution, and how many clips you need, and see an estimated cost across Sora, Runway Gen-3, Pika, Kling, Luma Dream Machine, and Haiper at a glance.

How it works

Nearly all generative-video platforms bill on the same shape:

cost ≈ seconds × per_second_rate × resolution_multiplier × clip_count

The per-second rate is the model’s base price, the resolution multiplier scales 720p → 1080p → 4K, and clip count covers a batch. The calculator applies each platform’s editable preset and sorts the results so the cheapest option for your exact specs is obvious.

Tips for cutting video spend

Generate at 720p first. Draft motion and composition cheaply, then re-render only the keepers at 1080p.
Keep clips short. Cost scales with seconds — six 4-second clips often beat one 24-second clip, and they hold motion better too.
Match tier to use. Social drafts don’t need the Pro model; reserve premium tiers for final hero shots.
Batch on a plan. Subscription credits are usually cheaper per second than pay-as-you-go top-ups once you’re generating regularly.
