💲 Credits estimator

Actual costs may change, see hailuoai.video for current pricing. The $ at Master column prices each generation on the $79.99/m Master plan ($0.00762/credit, the lowest cost per credit). Paid plans apply Seedance 2.0 at half credits, already reflected below.

Seedance 2.0 and Hailuo 3.0 bill per second, and a video reference is charged on its own length on top of the generated clip — at a lower per-second rate than the output. Image and audio references carry no per-second charge. The calculator below takes a video reference length so you can see the full cost.

Plan Monthly Credits/mo $/credit
Standard $9.99 1,000 $0.00999
Pro $34.99 4,500 $0.00778
Master $79.99 10,500 $0.00762
Max $199.99 20,000 $0.01000

Billed per second, so multiply by your duration (4–15). A video reference is charged on its own length as well, at the rate in the last column — image and audio references add nothing per second.

Interactive calculator — pick a plan and model for the per-generation cost:

Estimate only — it does not include any discounts or promotional pricing. Plan rates are the current published monthly prices.

💲 Music credits

Music bills against the MiniMax Audio balance, which is a separate ledger from the video credits above — a video plan does not pay for songs, and vice versa.

300 credits per song, whatever the model, length, or whether it has vocals. A quantity of 3 costs 900.

Both prices below are MiniMax’s own — what changes is which MiniMax product you buy:

Cost of one song  
minimax.io/audio — Pro plan, $99/mo (what this API uses) $0.01
platform.minimax.io — pay-as-you-go $0.15

A fifteenth of the price of MiniMax’s own developer API, for the same song.

Also worth knowing:

  • Other tiers carry 100,000 credits on Starter (~330 songs), 330,000 on Creator (~1,100), 750,000 on Standard (~2,500).
  • Pay-as-you-go adds $0.01 when the model writes the lyrics. On a minimax.io plan that is part of the same 300 credits.

Actual costs may change, see minimax.io for current pricing.

💲 Speech credits

Speech bills against the same MiniMax Audio balance as music — the same plans, so characters and songs draw on one pool.

Billing is per character — 1 credit on an hd model, 0.6 on a turbo one, so turbo costs 40% less and takes twice the text in a single call.

All three prices below are MiniMax’s own — what changes is which MiniMax product you buy:

Cost of 1,000,000 characters on speech-2.8-hd  
minimax.io/audio — Pro plan, $99/mo (what this API uses) $33
platform.minimax.io — Audio Subscription, Pro $99/mo $90
platform.minimax.io — pay-as-you-go $100

A third of the price of MiniMax’s own developer API, for the same audio.

Also worth knowing:

  • Other tiers carry 100,000 credits on Starter, 330,000 on Creator, 750,000 on Standard.
  • Voice cloning costs no credits. It uses a voice slot — 10 on Starter up to 250 on Pro — which POST speech/delete-voice frees and GET speech/equity counts.
  • Emotion tags are free. Sound and pause markup is billed as ordinary text.
  • On turbo it is $19.80 a million against pay-as-you-go’s $60. MiniMax discounts both sides by the same 0.6, so the gap stays a third whichever model you pick.

Actual costs may change, see minimax.io for current pricing.
