Subscription or API: the break-even math
The one formula
Effective subscription rate = monthly fee ÷ seconds you'll realistically generate. If that beats the API's per-second rate for the same model, subscribe. The honesty is in the word realistically — plans are priced against your ambitions, profits are made on your actual usage.
| Plan | Fee | Break-even vs API |
|---|---|---|
| Kling Standard ($6.99, 660 cr) | $6.99/mo | Wins from ~70 standard seconds/mo — almost anyone posting weekly |
| Runway Pro ($28, 2,250 cr) | $28/mo | Wins if you'd burn 2,250+ API credits — plus bundles Veo/Kling/Seedance access |
| Sora 2 — API only | pay-per-use | No subscription math to do; $0.10/s is the price at any volume |
| Google AI Ultra ($249.99) | $249.99/mo | Only wins over Vertex per-second rates at heavy Standard-tier volume |

The decision beyond the math
APIs win on flexibility (spiky usage, multi-model pipelines, no breakage) and subscriptions win on psychology — a sunk monthly fee makes iteration feel free, and creators who iterate more make better content. That behavioral effect is real budget value for solo creators. Teams and pipelines should default to API pricing and let the numbers decide. Full credit conversions in the reference tables.
