- Kling 3.0: Kling’s own app on Standard annual credits is cheapest at 720p and 1080p ($5.40 720p no audio, $10.80 1080p with audio); Luma is cheapest at 4K ($33.08). Kling 3.0 Turbo: Luma ($9.00 at 720p).
- Dearest everywhere: the Runway app. Kling 4.0 at 720p is $20.74 even with Runway’s 25% discount ($27.65 list) on Standard annual credits; Kling 3.0 costs 2.7–2.9× the Kling app.
Prices checked Nov 11, 2026, about 9pm Central. Rows not yet in ClipCost’s ranked data (Runway app Kling 4.0, Luma Kling 4.0 Flash, Runway API Kling 4.0 list and Flash) are shown as “not ranked (~#N)” = where that price would sit among the 237 ranked rates.
Basis: usable = 3 attempts (1 + 2 retries) of 30 seconds, the same as the calculator. Plan credits use the cheapest paid plan billed annually: Kling Standard $6.60/month for 660 credits ($0.01), Luma Plus $25 for 10,000 ($0.0025), Runway Standard $12 for 625 ($0.0192). API credits: Runway $0.01 each; Kling API rates as printed in dollars. Plan credits expire monthly, so plan rates assume you use your whole allowance. Cost only, not quality.

Runway’s app does not print the discounted Kling 4.0 rate per second: its credits page lists 16 / 24 credits per second and its pricing page says “25% off Kling 4.0 generations until November 30”, showing 1080p at 118 → 89 credits per 5 seconds (about 23.6 → 17.8 per second, a touch under the credits page’s 24). ClipCost applies 25% to the credits-page rates (12 / 18 credits per second). With input or reference video, Kling’s API bills 0.6 / 0.9 units per second of output × 2 (or input + output), and the Runway API 7.52 / 11.28 credits (promo); details on Kling 4.0 cost.

Kling 3.0: usable 30s by storefront
Usable 30-second clip (3 attempts) and rank of 237. Cheapest per row in bold. Kling 3.0 makes 3–15 seconds per generation, so 30 seconds is two clips.
| Kling 3.0 tier | Kling app (Standard annual) | Luma Plus (annual) | Kling API | Runway API (Std = 720p, Pro = 1080p) | Runway app Standard (Std / Pro) |
|---|---|---|---|---|---|
| 720p, no audio | $5.40 (#51=) | $6.75 (#70=) | $7.56 (#83=) | $8.10 (#87=) | $15.55 (#159=) |

Kling app rates: 6 / 9 / 8 / 12 credits per second (720p no audio / 720p audio / 1080p no audio / 1080p audio) from Kling’s VIDEO 3.0 guide; Kling app 4K is not on that guide. Runway prices Kling 3.0 as Std and Pro without stating a resolution; ClipCost pairs Std with 720p and Pro with 1080p. Runway’s app lists Kling O3 4K at 43 credits per second, not plain Kling 3.0 4K. Luma prices Kling 3.0 and 3.0 Omni the same. Pika also sells Kling 3.0 at 720p — see Which AI video storefront.
Kling 3.0 Turbo: Luma vs Kling API vs Runway app
| Kling 3.0 Turbo | Luma Plus (annual) | Kling API | Runway app Standard | Runway API |
|---|---|---|---|---|
| 720p | $9.00 (#97=) | $10.08 (#114=) | $24.19 (#194) | Not listed |
| 1080p | $11.03 (#127=) | $12.60 (#138=) | $27.65 (#204=) | Not listed |
Luma: 40 / 49 credits per second; Kling API: $0.112 / $0.14 per second with native audio; Runway app: 14 / 16 credits per second (audio not stated). Kling’s app rate for 3.0 Turbo is not on its public guide.
Why the gap: what one credit costs
- Kling app: $0.01 per credit on Standard annual; Kling’s own Kling 3.0 rates are the lowest per second, but membership credits expire after a month. See Kling credits explained.
- Luma Plus: $0.0025 per credit; per-second credit counts are high (53 for Kling 4.0 at 720p) but each credit is cheap. See Luma partner models cost.
- Runway app: $0.0192 per credit on Standard annual, almost 2× a Runway API credit, for the same or higher credits per second (Kling 4.0: 16 in the app vs 15.7 list on the API). See Runway credits explained.
- Runway API: $0.01 per credit, pay as you go; partner Kling rates on Runway API partner models cost.
- Kling API: priced in units (1 unit = $0.14 list on Kling 3.0 and older; Kling 4.0 and 4.0 Flash rows print 1 unit = $0.157); prepaid packages. See Kling API pricing.
Which to buy (on cost)
- Kling 4.0 before Nov 30: Runway API ($11.30 at 720p). If you already pay for Luma Plus, it is only $0.63 more per usable 30s.
- Kling 4.0 from Dec 1: Luma Plus ($11.93 / $17.78).
- Kling 4.0 Flash: Luma ($7.20).
- Kling 3.0 at 720p / 1080p: Kling’s own app, if you use your monthly credits; otherwise pay-as-you-go via Kling’s API ($7.56) or the Runway API Std no audio ($8.10).
- Avoid for cost: the Runway app for any Kling model, unless you need Kling inside a Runway workflow. Compare: Runway vs Kling cost and Luma vs Runway cost.
Honest flags
- Kling’s app price for Kling 4.0, 4.0 Flash and 3.0 Turbo is not on a public Kling page we could read (the pages are JS-rendered), so those cells say unverified. Kling shows the exact credit cost before each generation — check in-product.
- Runway app Kling 4.0, Luma Kling 4.0 Flash and the Runway API Kling 4.0 list / Flash rates are shown page-only (“not ranked, ~#N”); they are not in ClipCost’s calculator or ranked data yet.
- Runway’s app discount is 25% and its API discount 20%; both end November 30 (the API says UTC). The Runway app 720p discounted rate is ClipCost’s 25% of 16, not a printed number.
- Kling app plan price ($6.60/month annual for 660 credits) was last verified Oct 17, 2026; the membership page did not return a price table today. Per-second Kling 3.0 credit rates were re-checked today.
