Real cost breakdown

Moderate monthly use = roughly 8 finished videos (avg 2 min each). On HeyGen Creator at $29/mo you get 15 credits — each video costs ~$1.93/credit, so 8 videos runs you $29 flat. On Synthesia Starter at $29/mo you get only 10 minutes total — 8 x 2-min videos = 16 minutes, blowing past your cap and forcing an upgrade to the $89/mo plan. Real cost for identical moderate workload: HeyGen $29/mo vs Synthesia $89/mo. That's 3x more expensive for Synthesia at this usage level. Per minute of output: HeyGen ~$1.93, Synthesia ~$8.90 on Starter, ~$3.56 on the $89 plan. HeyGen wins the cost battle decisively.

When to switch

DROP HeyGen FOR Synthesia when: you're producing formal corporate training or compliance content where avatar realism is non-negotiable, you need 140+ language support with accurate lip-sync, or your company requires ISO 27001 compliance by policy. DROP Synthesia FOR HeyGen when: you're a solo creator, marketer, or small team making more than 10 min of video per month on a budget, you want a custom avatar without paying $89/mo, or you need faster generation times and a bigger template library for social/marketing content.
