How many days does a $250 Sume wallet last at 10 clips a day

A $250 wallet lasts 20 days at 10 ten-second Wan 3.0 clips a day ($1.25 a clip at 720p) and 4 days at the same rate on Seedance 2.5 ($5.78 a clip). Those figures use Sume's Video Router prices, which are the provider list rate times 1.25, rounded up to the cent for each job (read 2026-10-06).

Runway is the number that matters for a content calendar, because a wallet is prepaid. Sume reserves the billable amount when you submit, captures it on success and refunds it on failure, so the balance you read is the balance you can spend. The tables below turn a top-up into days of output for the two ends of the price range.

Reading the tables

Days are rounded down, because the day on which the wallet cannot cover a clip is a day without output. The price gap between the two models is about 4.6 times, so the same top-up buys 4.6 times more days on Wan 3.0 than on Seedance 2.5 at 720p. Which model is right depends on the look you need, not on the runway, so use these tables to size the top-up after you choose the model.

Plan for retakes before you plan for days. If one clip in three is kept, the runway in kept clips is a third of what the table shows.

• Top-ups are a dashboard operation. The public API reads GET /v1/balance and GET /v1/usage, and does not create a top-up.
• A balance lower than one clip's price returns 402 insufficient_credits at submit, before any provider work starts.
• Failed jobs are refunded, so a failure does not shorten the runway.
• Concurrency comes from the plan, not from the wallet, so a bigger top-up does not make clips render faster.

Compute your own runway

Replace the price with the billed price of the model and duration you use, which you can read from the catalog or from the first job's usage row.

def runway_days(balance: float, clips_per_day: int, price: float) -> int:
    cents = round(balance * 100)
    daily = clips_per_day * round(price * 100)
    return cents // daily


PRICES = {"wan-720p-10s": 1.25, "seedance-2.5-720p-10s": 5.78}
for name, price in PRICES.items():
    for balance in (100, 250, 500):
        print(name, balance, [runway_days(balance, n, price) for n in (3, 10, 20)])

A month, a quarter, a year

At 10 clips a day a 30-day month is 300 clips. That is $375.00 on Wan 3.0 and $1,734.00 on Seedance 2.5, so a month of the cheaper model costs less than a week of the dearer one. A 90-day quarter is $1,125.00 and $5,202.00. These are the numbers to put next to a plan fee when you decide what the monthly line should be.

Remember that the plan and the wallet are two different bills. The subscription plan is billed separately, and the wallet pays for the generation. Workspace concurrency is a dispatch limit that controls how many jobs run at once, not how much you can spend, so the wallet is the line that scales with output.

When to top up

Set the top-up trigger in days, not dollars. If your team needs a week of lead time to approve spend, top up when the balance covers 10 days at your current rate, and check it with the balance read on a schedule. The rate that drives the trigger is the last seven days of spend from GET /v1/usage, which is more honest than the rate you planned.

The current prices are in the Video Router catalog, and the plan side of the bill is on the pricing page.
