AI Avatar Pricing Has No Common Unit. Here Is One.

A new model launched last week as "the cheapest long-form AI avatar model on the market," and the comparison most people ran next was simple: its per-minute price against the $29 plan they already know.

It feels like due diligence, and it's easy to run without noticing the problem: in AI avatar pricing, two per-minute figures rarely count the same minute. The headline price and the plan price measure different things, and on the launch page itself the headline comes in four versions.

This post won't tell you which avatar tool is cheapest. From the pricing pages alone, nobody can. What it will do is give you one unit that makes AI avatar pricing comparable, show the arithmetic on real pages read today, and mark the place where the arithmetic stops working. We found that place through a mistake of our own.

One model, four starting prices

VidRush's page for Persona I, read in a browser on 2026-09-23, states four different entry prices for the same model, and none of them says what it assumes.

Noah Morris announced Persona I on X(opens in new tab) on September 18 as "as low as $0.6/min," adding that "competitors charge $1+." The post drew a lot of attention, and the claim is the reason this one exists. Five days later, the Persona I page(opens in new tab) says something else, several times:

• The hero: "Starting at $0.53 per finished minute."
• The comparison block, two scrolls down: "From $0.85/min."
• The same block: "10 minutes with VidRush: from $5.30."
• The footer: "Starting at $0.76/min. Make your next 10-minute long-form video from $7.60."

The plan cards clear up part of it. On the monthly toggle, which is the default, Starter is $99 a month for 116 minutes ($0.85), Creator $239 for 323 ($0.74), Pro $639 for 918 ($0.70). The nearest thing to $0.53 sits at the far end of the calculator on the pricing page(opens in new tab): pick Persona I, slide to 7,677 minutes a month, switch to yearly billing, and it shows $4,158 a month at $0.54 a minute. Billed monthly, the same volume shows $0.65.

Sources: vidrush.ai/persona-i and vidrush.ai/pricing, read in a browser on 2026-09-23; launch post on X, dated September 18.

None of this is dishonest. Each figure is true under some plan, toggle and volume. The problem is that "cheapest" is a claim about a number, and VidRush's two pages hand you seven of them, eight with the launch post, without the condition that selects one.

The per-minute price assumes you use every minute

A published per-minute rate is what you pay only if you use the whole allowance, every month. Use less and the real rate climbs, fast.

VidRush's own calculator shows it without meaning to. Set it to 6 minutes a month on Persona I and it still reports "$0.85 / minute," next to the line "Covers your 6 minutes a month, 5% of your credits." The plan is still $99. Six minutes for $99 is $16.50 per minute you actually made.

Our arithmetic on VidRush's Starter plan as listed on 2026-09-23: $99 divided by minutes made. Rollover doesn't rescue a steady month: if you make the same amount every month, you still pay $99 for it.

Expiry rules decide how much of that curve you live on, and they differ everywhere:

• headcast(opens in new tab) says it plainly: "Plan minutes do not roll over; bought minutes do." Extra minutes cost $1.00 each and never expire.
• HeyGen(opens in new tab) lets monthly credits live one extra cycle, "up to 60 days," and lets annual credits pile up until renewal.
• VidRush's calculator says unused credits roll over "up to 1.5× your monthly credits." The pricing block on the Persona I page, a few hundred pixels higher, says "Minutes reset every month."

So the honest per-minute figure depends on how steady your volume is, and only you know that.

Same vendor, same model, four prices

HeyGen's Avatar IV costs between $0.64 and $1.50 a minute on the same entry plan, depending on the avatar type and the billing toggle. Same company, same plan.

The Creator plan(opens in new tab) is $29 a month, or $24 billed yearly, and includes 600 credits. HeyGen's credits article(opens in new tab), read on 2026-09-23, prices Avatar IV at 16 credits a minute for a Photo Look and 31 for a Video Look. So 600 credits buy 37.5 minutes of the first or about 19 of the second. If every credit goes to Avatar IV, a Photo Look minute costs $0.77 monthly or $0.64 yearly, and a Video Look minute $1.50 or $1.24.

Our arithmetic from heygen.com/pricing and HeyGen's credits help article, both read in a browser on 2026-09-23: $29 or $24 divided by 600 credits over 16 or 31 credits a minute.

Two more things make the HeyGen minute a different object from the VidRush minute. HeyGen's Avatar IV guide(opens in new tab) says "we only charge for the actual seconds of avatar generation, not the entire video length." VidRush and headcast both bill the finished minute, whatever it took to make. A ten-minute video with four minutes of presenter on screen is four minutes on one meter and ten on the other.

And the number moves under you. The same credits article says Creator "now includes 3x the monthly credits than before." Any spreadsheet built on the old allowance needs redoing.

Where the arithmetic stops: our Arcads mistake

Some prices can't be turned into a per-video number at all, and we learned that when one reached our own comparison page.

On 2026-07-16, the day we set up Clipwright's repository, our competitor notes got a line saying Arcads costs about $11 per video. We hadn't measured it. The figure came from another vendor's own positioning, a list of what its competitors supposedly charge per video, and we repeated it without checking. The same number also had a derivation attached: a $110 entry plan, divided by "roughly ten videos."

On 2026-09-15 that line reached the published version of our Arcads comparison page, labelled as checked that day against their public pages. It wasn't. Arcads shows prices only behind signup, and when we read them there, both premises failed. The $110 was the undiscounted Starter price, $77 after a 30% discount that day, and the plan covered up to 50 videos. The page was corrected 16 minutes later.

We didn't replace it with a better per-video number, because Arcads doesn't sell one. Arcads' own FAQ says: "Can I pay per video? No." Each plan carries three ceilings at once, and the page doesn't say which one you hit first.

From Arcads' signed-in pricing page, 2026-09-15. Dividing $77 by any one ceiling gives an upper bound that changes with the ceiling you pick.

The cost was a wrong competitor price in a publishing commit, on a page whose whole job is a fair comparison, marked as verified when it wasn't. The number was wrong, but the deeper error was the unit. Since then every competitor price we keep carries a capture date and a unit, we never divide a plan by one of several ceilings, and Arcads' per-video cell stays empty on purpose. A per-video comparison with them needs one script rendered in both tools and two invoices side by side, and until we run it we publish no per-video figure for them.

How to normalise AI avatar pricing yourself

Here is the unit: dollars per minute of finished video you will actually publish, at your real monthly volume. Everything below is a step toward that number.

1. Write down your month first. How many videos, how long, which model. Do this before you open any pricing page.
2. Read each page in a browser and note the toggle. Monthly or yearly, which tier, and the date. We've been caught by a toggle before, on a page with a $2 gap between its two states.
3. Convert to the vendor's own meter. Credits per second, minutes of finished video, or avatar-seconds only. Note which, because a HeyGen minute and a VidRush minute measure different things.
4. Divide the plan price by the minutes you will use rather than the minutes included. If your volume swings, apply that vendor's expiry rule to your worst month.
5. Where the meter is hidden, stop. Write "not computable" and run one script through the tool to get a measured figure.

These rows describe two days in September, and any of them may have changed by the time you read this, so check the dates before you rely on a row.

FAQ

What is the cheapest AI avatar generator?

It can't be answered from pricing pages. Published per-minute rates assume you use every included minute, they change with the billing toggle and the tier, and vendors meter different things: some bill the finished minute, others only the seconds the avatar is on screen. The cheapest tool is the one with the lowest cost per minute you actually publish, at your volume, and only you have that number.

Is a per-minute price the same across AI avatar tools?

No. On 2026-09-23, VidRush and headcast billed the minute of finished video, while HeyGen's Avatar IV guide says it charges "only for the actual seconds of avatar generation." A ten-minute video with four minutes of presenter on screen costs four minutes on one meter and ten on the other.

Why does my real cost per minute come out higher than the pricing page?

Because the page divides the plan price by the minutes included, and you pay the plan price whether you use them or not. On a $99 plan with 116 minutes, making 6 minutes a month costs $16.50 per minute made. Expiry rules decide whether the unused part carries forward, and they differ by vendor.

What we do, and where we're not in this fight

We build in this category, so treat this as the view of an interested party.

Clipwright is a short-clip API for agents, not a long-form channel tool, so it isn't in the comparison above. Its meter is the one this post argues for: you pay for the length of the finished video, rounded up to the next whole second, out of credits that never expire. That makes a run priceable before it starts. It also commits us to absorbing vendor price moves ourselves, and we've gotten the billing rule wrong before, charging for a video that never arrived.

If you're choosing an avatar tool this week, open the calculator on each pricing page, set it to your real monthly minutes, and write down the number it shows alongside the plan price divided by those minutes. If the two don't match, the second one is your price.
