Runway credits calculator

Runway pricing is easiest to compare when credits become dollars per second. Use this guide to understand the conversion before you choose Gen-4.5 or Gen-4 Turbo.

Runway model	Example credits / sec	Credit price	Estimated $ / sec	Best use
Gen-4 Turbo	5	$0.01	$0.05	Drafting, fast iteration, cheaper B-roll.
Gen-4.5	25	$0.01	$0.25	Hero shots, cinematic output, quality-first work.

The formula

Credits per second × price per credit × seconds × retake multiplier = estimated project cost. If you make a 10-second Gen-4.5 shot at 25 credits per second, that is 250 credits before retakes. At $0.01 per credit, the raw cost is $2.50; with a ×1.5 retake profile, the usable estimate is $3.75.

When Runway credits get expensive

Credits are clear once converted, but the same wallet can drain at different speeds depending on the model. That makes Runway great for creators who switch between fast drafts and high-quality final shots, but risky if you draft everything on the premium model.

FAQ

How much is one Runway credit worth?

ClipBudget's tracker uses $0.01 per credit for developer pricing calculations, then converts model credit burn into dollars per second.

Why does Gen-4.5 cost more than Gen-4 Turbo?

It burns more credits per second. The trade-off is higher visual quality, so use it for final hero shots rather than every draft.
