AI Video Generation Costs Are Eating Your Budget: Runway, Kling, and Pika Pricing Reality Check
Runway Gen-4 charges $0.12 per second. A 30-second video costs $3.60. Generate 1,000 videos and you've spent $3,600. Here's the real math behind AI video pricing and how to budget for it.
November 10, 2025 6 min read
You want to add AI video generation to your product. You test Runway Gen-4. The results are stunning. You estimate 1,000 videos per month at maybe $100-200 total.
Your first invoice is $3,600.
AI video generation is expensive in ways that image generation is not. The pricing is per-second. The credits systems are confusing. The actual costs are 10-20x higher than initial estimates. This is a major consideration for startups planning video features.
You need to understand the real math before building features around AI video.
How Video Generation Pricing Actually Works
Unlike image generation (flat fee per image), video is priced per second of output.
Why this matters:
A 5-second video and a 10-second video cost different amounts. Video length directly determines cost. This seems obvious, but it changes how you budget and design features.
The credit system complexity:
Most services sell "credits" instead of direct per-second pricing. You buy credits, then spend them generating videos. The conversion rate varies by:
Video length (more seconds = more credits)
Quality tier (4K costs more than 1080p)
Generation speed (turbo mode costs more)
Model version (newer models cost more)
This makes pricing opaque and budget planning difficult.
Stop planning and start building. We turn your idea into a production-ready product in 6-8 weeks.
Runway's Gen-4 is the current quality leader for AI video generation.
Pricing structure:
Standard mode: 12 credits per second
Turbo mode: 6 credits per second (faster, lower quality)
Credit cost: $1.00 per 10 credits = $0.10 per credit
Real pricing:
Actually, Runway's math is:
Gen-4: 12 credits/sec = $0.12/sec (at $10 per 100 credits)
Gen-4 Turbo: 6 credits/sec = $0.06/sec
Let me recalculate based on actual Runway pricing:
Actual Runway costs per video:
Monthly volume math:
That's substantially more expensive than any image generation service.
Subscription tiers:
Standard: $12/month for 125 credits (~10 seconds of Gen-4 video)
Pro: $28/month for 625 credits (~52 seconds)
Unlimited: $76/month for 2,250 credits (~188 seconds)
Enterprise: Custom pricing for volume
For any meaningful product usage, you'll need credits beyond subscriptions.
Kling AI: The International Competitor
Kling AI (from Kuaishou) is a Chinese competitor with competitive quality.
Pricing (approximate, varies by region):
Roughly $0.60 per 10-second clip in standard mode.
Real costs:
Comparison to Runway:
Considerations:
Quality competitive with Runway for many use cases
Less documentation and English support
Fewer integration options
Data sovereignty concerns for some customers
Pika: The Developer-Friendly Option
Pika focuses on ease of use and developer experience.
Pricing (approximate):
~$0.15 per 5-second video
Real costs:
This makes Pika significantly cheaper than Runway:
Trade-off:
Pika is cheaper but quality is a step below Runway Gen-4. For many use cases, the quality difference doesn't justify 4x cost.
The Hidden Costs Nobody Warns You About
Failed generations: You pay for failed outputs.
In practice, 30-50% of generations need regeneration. Budget accordingly.
Iteration costs: Users regenerate until they get what they want.
Storage costs: Video files are large.
Storage costs are small compared to generation, but they add up.
Processing costs: You probably need to post-process videos.
Total cost per video:
Credit System Math: Converting to Real Dollars
Services use credits to obscure actual costs. Here's how to convert.
Runway math:
Always calculate: Dollars per second of output, not credits per second.
Formula:
Use Case Budget Planning: Real Project Examples
Use case 1: Social media content tool
Feature: Generate 10-second video clips from text prompts
Estimated usage: 5,000 videos per month
Your pricing to break even:
Use case 2: Product demo videos
Feature: Turn product screenshots into animated demos
Estimated usage: 500 videos per month, 30 seconds each
Use case 3: Avatar videos
Feature: Generate talking head videos from text
Estimated usage: 2,000 videos per month, 5 seconds each
Key insight: For avatar videos specifically, specialized services are often more cost-effective than general video generation.
Cost Optimization Strategies
1. Length limits: Enforce maximum video duration.
2. Tier-based access: Limit generations per user tier.
3. Quality tiers: Use cheaper models for previews.
4. Batch processing: Generate videos async during off-peak hours.
5. Caching: Store and reuse identical generations.
We implement these patterns in every video generation project because costs spiral quickly without controls.
Understanding these cost optimization strategies is critical before you commit to pricing your video generation product.
Subscription Model Economics
Can you build a sustainable business on AI video generation?
Math:
Successful models:
Freemium with aggressive limits
Free: 3 videos/month
Starter: $9/month for 10 videos (lose money to acquire)
Pro: $49/month for 100 videos (profitable)
Enterprise: Custom (high margin)
Credit-based (like services themselves)
Sell credits, not subscriptions
Users buy what they need
Higher margin but less predictable revenue
Hybrid
Base subscription with included credits
Purchase additional credits as needed
Best of both models
Reality check:
Most video generation features are loss leaders. They attract users but need other revenue streams to be profitable. Plan accordingly.
Service Comparison: Which to Choose
Choose Runway Gen-4 if:
Quality is paramount
Budget can support $0.12/second
Targeting professional/enterprise users
Building portfolio/showcase tool
Choose Runway Turbo if:
Need balance of quality and cost
$0.06/second is acceptable
Targeting prosumer market
Social media content use case
Choose Pika if:
Cost is primary concern
Lower quality acceptable
High-volume use case
Building MVP to test market
Choose Kling if:
International audience
Cost-conscious
No data sovereignty requirements
Comfortable with less polished service
For most products: Start with Pika for MVP. Migrate to Runway if users demand quality and are willing to pay for it.
The Budget Reality Check
Before building video generation features:
Calculate minimum viable economics:
Common mistake: Building the feature first, discovering costs later.
Right approach: Model economics before writing code.
Monitoring and Alerts
Track spend in real-time.
Dashboard queries:
Building This: 4-Week Implementation
Week 1: Cost modeling
Calculate realistic usage estimates
Model economics across services
Test quality with sample prompts
Choose primary service
Week 2: MVP with hard limits
Integrate chosen service
Implement strict length limits
Add user tier limits
Basic cost tracking
Week 3: Optimization
Add preview/approve flow
Implement caching
Build retry logic with exponential backoff
Set up cost monitoring
Week 4: Production hardening
Configure alerting
Add fallback providers
Implement queue for async processing
Document costs for team
Don't skip week 1. The projects that fail are the ones that build first and model economics never.
For MVP development, starting with realistic cost modeling prevents expensive pivots later.
The Uncomfortable Truth
AI video generation is currently too expensive for most consumer use cases at scale.
Services that work:
Low-volume professional tools
Enterprise products with high ARPU
Premium features in existing products
Demo/marketing tools (not user-facing)
Services that struggle:
High-volume consumer apps
Free or low-cost tiers
Viral/social features with unlimited use
Products where video is core feature
You can build AI video features. You probably can't build a profitable business solely on AI video generation at current pricing.

Most marketing automation apps treat AI as a feature to add later. Here's why that approach fails—and how to architect AI-native marketing automation from day one.
