Sume Scale $400 includes $800 of usage: fee per usage dollar by plan

Sume's plans do not charge the same fee for each dollar of included usage. Pro is $40 for $40, Startup is $120 for $140, and Scale is $400 for $800, so the fee per included dollar falls from $1.00 to $0.86 to $0.50. The catch is that the discount only exists if you actually spend the allowance. Included usage figures come from Sume's plan catalog; the Billing and subscription page in the dashboard shows how much included usage is left on your workspace.

Fee per dollar of included usage

Included usage is billed at Sume's rates, which are the model provider's list price times 1.25. The table divides each monthly fee by its allowance, then shows how much provider list price the allowance covers (allowance divided by 1.25).

What the allowance buys in video

Take 15-second Wan 3.0 clips at 720p, which cost $1.88 each after Sume rounds the job up to the next cent. Divide each allowance by that price and you get the clip counts below. They are whole clips only, and they assume nothing else is spent from the same pool.

When the cheaper rate is not cheaper

Scale only wins on price if you use most of the $800. A workspace that spends $200 a month pays $400 on Scale, but $200 on Pro, because usage above the Pro allowance is billed on top of the fee. Concurrency is the other half of the decision: Pro runs 4 jobs at once, Startup 8 and Scale 20, which matters more than price for batch work.

A fair rule is to pick the plan from your expected monthly spend, not from the best-looking ratio. The break-even post and the cost per concurrency slot post cover the other axes.

Two cautions apply when you use the ratio to choose. The ratio assumes the whole allowance gets spent, and included usage does not roll over, so a month at half the allowance doubles your effective fee per dollar. Also, usage is only one reason to pick a plan: Pro runs 4 jobs at a time, Startup 8 and Scale 20, and a larger queue can matter more to a team with a deadline than a lower fee ratio. Start from last month's real usage and your busiest batch, then read the ratio as a tiebreaker.
