We Ran the Credit Math on Runway, Kling, and Veo 3 — Here's What a 60-Second Video Actually Costs

Runway’s $28/month Pro plan sounds reasonable until you do the math: 2,250 credits buys you roughly 187 seconds of Gen-4 footage. Kling 3.0’s $25.99/month Pro tier gives you 3,000 credits — enough for about 250 seconds of 1080p output. Same budget. Sixty-three more seconds of video.

The post-Sora shutdown landscape is three platforms now: Runway, Kling, and Veo. They all hide pricing behind credit systems on purpose. Credits obscure per-second cost, make month-to-month comparison impossible, and lock you into tiers based on feature bundles, not output. We converted every plan into dollars per generated second. The result: Kling wins on raw cost, Veo 3.1 is a trap, and Runway Pro is the middle ground.

The Cost-Per-Second Breakdown

Here’s what you actually pay per second of usable video across all three platforms:

*Based on Runway pricing and Kling 3.0 complete guide breakdowns; Veo 3 figures from per-second cost comparison.

Kling 3.0 Pro wins by a mile on raw cost-per-second: $0.0087. Runway Pro sits at $0.012. Veo 3.1 at Google AI Ultra ($249.99/month) lands between $0.15–$0.50 per second depending on model choice. That’s 17–57× more expensive than Kling.

The Iteration Cost Nobody Admits

Here’s the beat everyone skips: a usable clip doesn’t come out of the first generation. In practice, one keeper take requires three to five attempts. Bad framing, bad timing, output doesn’t match the prompt, you regenerate.

That means real-world cost-per-deliverable is 3–5× the headline rate. Kling Pro’s $0.0087/second becomes $0.026–$0.044 per second when you account for iteration waste. Runway Pro climbs to $0.036–$0.060. Veo 3.1 Ultra hits $0.45–$2.50 per usable second.

Suddenly the tiers look different. Runway’s Unlimited plan ($76/month, no credit ceiling) starts making sense if you’re iterating. Kling’s Pro tier remains unbeatable for volume work. Veo only makes sense if you’re chasing a specific aesthetic Veo produces that Runway or Kling can’t match — which is true sometimes, but not often enough to justify the markup.

The Verdict

Kling 3.0 Pro is the value leader. $25.99/month, 3,000 credits, approximately 250 seconds of 1080p output, and the lowest per-second cost in the market. If you’re shipping volume and iteration is part of the workflow, Kling eats Runway’s lunch.

Runway Pro is the middle ground. $28/month for 2,250 Gen-4 credits gives you flexibility and a consistent output quality. The UI is smoother, the model is battle-tested, and the extra $2/month buys you peace of mind if you’re not sure what you’re building yet.

Google AI Ultra / Veo 3.1 is a tax on aesthetic preference. $249.99/month is indefensible on cost-per-second alone. Pick it only if you’ve tested Veo’s output against Runway and Kling, and Veo’s quality wins the shoot. Marketing copy will tell you Veo is the future; the math tells you it’s expensive today.

We have no affiliate relationship with any of these platforms — this is just the math.

The credit system exists so you don’t compare. Now you can. (We cry about opaque billing systems so you don’t have to.)
