HeyGen credit rollover: one cycle monthly, until renewal annual

HeyGen rolls unused credits over, but the length depends on how you pay: monthly subscribers keep leftovers for one more cycle, annual subscribers accumulate credits until the plan renews. That is the wording on HeyGen's pricing page, read on 2026-10-13. Sume plan credits do not roll over at all; they expire at the end of each billing period.

So the billing cadence you pick at HeyGen changes how much of a quiet month you get back. This post shows the plan numbers from the page and the equivalent rules on Sume.

The page lists the plans below. Credits are described as one currency for video and asset creation. The rollover rule is stated once for all subscribers rather than per plan.

What the rollover rule changes

On a monthly plan, a month you under-use is partly saved for exactly one extra cycle. If you hold Creator and spend 300 of 600 credits, the other 300 stay available into the next cycle, and then lapse if still unspent, per the page's one-cycle wording.

On an annual plan the page says credits accumulate until renewal. That favors uneven demand: a campaign-heavy quarter can draw on the quiet quarters before it. The page does not state a cap for either mode, so treat any ceiling as unknown until you read the plan terms.

• Monthly: leftovers survive one more cycle.
• Annual: leftovers build up until the renewal date.
• Neither rule changes the price per credit; it changes how much you waste.

What Sume does with unused credits

Per Sume's Billing and credits, a paid plan adds its credits at the start of each period and they expire at the end of it, with no rollover. Free workspaces get one grant, once. Team workspaces can buy extra credits that last longer than plan credits but also expire, and Sume uses plan credits before purchased ones.

Spending is also reversible in one specific way: a request reserves credits on acceptance and captures them on completion, so a failed generation, or one cancelled before it starts, gives its credits back. Over MCP, dry_run=true returns usage.credits as an estimate with no submission. See Errors and credits for the 402 insufficient_credits case.

Choosing between them

If your avatar video work is lumpy and you can commit for a year, HeyGen's annual accumulation is the more forgiving rule. If your use is steady, or you prefer a pay-as-needed team balance with failed-job refunds, Sume's model avoids paying for a pool you may not finish. Compare against your last three months of real usage, not against list prices.
