How long a Sume top-up lasts at 10 AI videos a week on Pro

Ten 15-second Wan 3.0 clips a week at 720p cost about $81.47 a month on average ($18.80 a week times 52 divided by 12). Pro's $40 of included usage covers the first part, so the top-up wallet pays about $41.47 a month. A $500 top-up lasts about 12.1 months, which is right at the 365-day expiry, so only a few dollars lapse; a $1,000 top-up would lose about $502 to it.

How the draw works

Credits are spent in a fixed order: included usage first, then top-ups. Included usage renews each month with no rollover. So every month you spend $40 from the allowance and the remainder from the wallet. Top-up amounts run from $10 to $1,000, with presets of $50, $100, $500 and $1,000, and each lot lasts 365 days. Included usage figures come from Sume's plan catalog; the Billing and subscription page in the dashboard shows what is left on your workspace.

Which is better, top-up or Startup

Startup is $120 with $140 included, which would cover this usage but costs more than Pro plus the $41.47 draw: Pro is $81.47 a month effective, Startup $120. Startup becomes better above $120 of monthly usage, or when you need 8 concurrent jobs.

A lump-sum top-up is a way to pre-pay, not a discount. Top-ups are team-wallet only, so check your workspace type before planning around one; see the solo workspace limit and the API balance view.

Treat the months column as an estimate. The 52 divided by 12 conversion gives about 4.33 weeks a month, while your real billing months vary, and any retake or extra step such as narration or captions raises the draw and shortens the top-up. Included usage also resets monthly, so a quiet month leaves the top-up untouched. A smaller $100 top-up topped up again when needed is a simpler habit than one large lot that might expire.
