AI video generation is no longer just for big studios — but it can still get expensive fast if you don't understand how the pricing works. This guide breaks down exactly what you'll pay on every major platform so you can make smart decisions about your budget.
The Two Pricing Models
Most AI video platforms fall into one of two pricing structures:
- Subscription-based: Pay monthly, get an allotment of credits or "generation minutes". Unused credits often don't roll over.
- Pay-as-you-go: Buy credits when you need them, spend them on any model at any time. No monthly commitment.
Subscriptions win if you generate consistently high volumes every month. Pay-as-you-go wins for everyone else — occasional creators, agencies testing workflows, and anyone who wants to use multiple models without paying multiple subscriptions.
Platform-by-Platform Cost Breakdown
Kling (klingai.com)
| Plan | Monthly Cost | Credits/Month | Cost per 5s video |
|---|---|---|---|
| Free | $0 | 66 | Limited — slow queue |
| Starter | $9.99 | ~600 | ~$0.08 |
| Pro | $39.99 | ~3,000 | ~$0.07 |
| Premier | $99.99 | ~10,000 | ~$0.05 |
Note: Kling credits expire at end of billing period. If you don't use all your credits, you lose them.
Runway (runwayml.com)
| Plan | Monthly Cost | Credits/Month | Cost per 5s video |
|---|---|---|---|
| Basic | $0 | 125 (once) | Free tier limited |
| Standard | $15 | 625 | ~$0.12 |
| Pro | $35 | 2,250 | ~$0.08 |
| Unlimited | $95 | Unlimited* | ~$0.04 effective |
*Runway Unlimited throttles after heavy use. Not truly unlimited in practice.
Luma AI (lumalabs.ai)
| Plan | Monthly Cost | Generations/Month |
|---|---|---|
| Free | $0 | 30 videos |
| Plus | $29.99 | 200 videos |
| Pro | $99.99 | 2,000 videos |
Sora (openai.com/sora)
Sora pricing is tied to ChatGPT Plus and Pro subscriptions. As of March 2026:
- ChatGPT Plus ($20/mo): ~50 priority video generations/month, 1080p max
- ChatGPT Pro ($200/mo): Unlimited relaxed, 500 priority generations, 4K max
Sora doesn't offer true pay-as-you-go — you're always attached to a ChatGPT subscription tier.
Pika (pika.art)
| Plan | Monthly Cost |
|---|---|
| Free | $0 (150 credits/mo) |
| Standard | $8 |
| Unlimited | $28 |
| Pro | $58 |
The Hidden Cost: Multiple Subscriptions
Here's where most creators get caught. If you want to use both Kling and Runway — which many professionals do — you're looking at paying for two separate subscriptions:
- Kling Pro: $39.99/month
- Runway Standard: $15/month
- Total: $54.99/month before you generate a single video
Add Luma and Sora, and you're paying $150–200/month in subscriptions alone. That's before the cost of actual generations.
The Pay-As-You-Go Alternative
MotionAI gives you access to Kling 2.6, Kling 3.0 Pro, and Wan 2.2 on a pure pay-as-you-go basis. Here's how the credit packages work:
| Package | Credits | Price | Per Credit |
|---|---|---|---|
| Starter | 20 | $9.99 | $0.50 |
| Creator | 50 | $19.99 | $0.40 |
| Pro | 120 | $39.99 | $0.33 |
| Studio | 300 | $79.99 | $0.27 |
Credits never expire. One Kling 3.0 Pro 5-second video costs 1 credit (~$0.33 at Creator tier). No monthly commitment. No wasted credits. No multiple logins.
Who Should Pay for a Subscription?
If you generate more than 100 videos per month on a single platform, a subscription often wins on per-video cost. But consider the full picture:
- Do you actually use that many credits every month?
- Do credits roll over, or do you lose unused ones?
- Are you locked into one model, or do you want to mix and match?
- What's the cost of unused months during slower periods?
For most creators generating fewer than 50 videos a month or wanting access to multiple models, pay-as-you-go wins.
No subscription required
