How does HeyGen charge for videos?

HeyGen bills by video minute, drawn from a monthly credit allowance tied to your plan. Longer scripts and higher resolutions consume more credits, and unused credits usually do not roll over.

How do you convert words to minutes?

The calculator assumes about 140 spoken words per minute, a typical narration pace. Duration in minutes ≈ word count ÷ 140, rounded up because most tools bill partial minutes as whole minutes.

Are these exact HeyGen prices?

No. Credit costs and plan allowances are editable estimates based on published tiers and can change. Confirm the current rate in your HeyGen dashboard before committing to a paid plan.

Does 1080p really cost more?

On most plans higher-resolution export consumes more credits per minute or is gated to paid tiers. The calculator applies a resolution multiplier so you can compare 720p and 1080p side by side.

Is anything I type uploaded?

No. The calculator runs entirely in your browser. Your script length and settings never leave your device.

How HeyGen billing works

HeyGen meters video generation by spoken minute, deducted from a monthly credit allowance that depends on your plan. The two levers that drive cost are length and resolution:

minutes  = ceil(word_count / 140)
credits  = minutes × resolution_multiplier × number_of_videos

Narration runs at roughly 140 words per minute, so a 700-word script is about five minutes of finished video. Higher resolution (1080p) generally consumes more credits per minute than 720p, and most plans bill any partial minute as a full minute — which is why short clips can feel surprisingly expensive.

Tips to stretch your credits

Batch tightly: render only final scripts; re-renders burn fresh credits.
Trim filler: cutting 15% of words can drop you below a minute boundary.
Default to 720p for social drafts and reserve 1080p for hero videos.
Match your tier to volume — the higher tiers lower effective cost per minute once you exceed a few videos a month.
