Where unused credits go on HeyGen
HeyGen splits this column by how a buyer pays. Monthly subscribers keep unused credits for one further month, annual subscribers accumulate them to the renewal date, and after a cancellation nothing carries over at all. As of 2026-09-22.
| Who is buying | What the pricing page states |
|---|---|
| Monthly subscribers | Unused credits are kept for one more month |
| Annual subscribers | Credits accumulate to the renewal date |
| After cancelling | Credits do not carry over |
| Plans behind it | $29 a month for 600 credits, $49 for 1,000 and $149 for 1,500 |
Inclusion rule. Statements on the pricing page about credits that go unspent, grouped as the page groups them: by billing cycle rather than by plan tier. Order. Monthly first, then annual, then cancellation.
1Where HeyGen sits in this column
| Channel | Unused credits |
|---|---|
| Hedra | No answer, though the FAQ asks |
| HeyGen | Answered by billing cycle |
| invideo AI | A single sentence, and it is a refusal |
| Kling AI | A 180-day window, stated twice |
| Magnific | A year, with no monthly reset |
| Morph Studio | No answer on the page that asks |
| Pika | A feature bullet, not a rule |
| Runway | Three answers, one per plan |
| SceneMixer | Into one balance, with no lapse date |
| Synthesia | Not stated where the plans are priced |
Inclusion rule. Channels whose own priced pages say something about credits left unspent, including the ones that raise the question and leave it unanswered. A channel that never meters in credits has nothing to answer and is not listed. Order. Alphabetical by channel name.
2Answering by cycle rather than by tier is the rarer split
Channels that vary this answer usually vary it by plan: the expensive tier gets rollover, the cheap ones do not. HeyGen varies it by how often the card is charged, so the same plan behaves differently depending on whether it was bought monthly or yearly.
That turns the annual discount into two discounts. The obvious one is the lower monthly figure; the hidden one is that a year of allowances pools instead of expiring twelve times, which is worth more to a production working in bursts than the price cut itself.
3A one-month grace period is a partial answer with a clear edge
Keeping credits for one further month sounds generous and behaves as a cap. Two quiet months in a row and the first month's allowance is gone regardless, so the grace period smooths a single slow month rather than an irregular schedule.
The useful reading is arithmetical: a monthly subscriber can carry at most two months of allowance at once. Anything that depends on saving up for a heavy month beyond that needs the annual cycle or a different seller.
4Cancellation is where the pooled credits stop being an asset
The annual case accumulates credits to the renewal date and the cancellation case carries nothing over, which together mean a large pooled balance has no value outside the subscription that created it. It is a quantity of access rather than a prepayment.
Pages elsewhere in this register distinguish purchased credits, which persist, from plan credits, which do not. This page does not print a credit price at all, so every credit here is a plan credit and the distinction never arises.
