A creator who publishes weekly often makes the wrong decision by budgeting only the next upload. A more useful view separates required deliverables, approved footage already in inventory, and new generation demand for each week. This avoids buying credits for work that is already finished.
Map the calendar before counting credits
Consider a hypothetical four-week content schedule: one 60-second product overview in week one, two 30-second explainers in week two, three 20-second vertical clips in week three, and one 90-second recap in week four. Total finished runtime is 270 seconds, but that does not mean 270 seconds must be newly generated. Some shots may come from approved inventory or already cleared footage.
| Week | Target deliverables | Final runtime | Approved reusable footage | New runtime estimate |
|---|---|---|---|---|
| 1 | One product overview | 60 s | 0 s | 60 s |
| 2 | Two explainers | 60 s | 12 s | 48 s |
| 3 | Three vertical clips | 60 s | 24 s | 36 s |
| 4 | One recap | 90 s | 36 s | 54 s |
| Total | Seven deliverables | 270 s | 72 s | 198 s |
The inventory figures are assumptions for this example. Confirm whether reused seconds are actually approved, fit the new message, and carry adequate reuse rights. If not, move them back into the new-generation column.
Convert weekly demand to credits
With six-second source clips, the 198 seconds of new approved footage require about 33 accepted clips. At an illustrative two attempts per accepted clip and four credits per generated second, the baseline forecast is 33 × 2 × 6 × 4 = 1,584 credits. This assumes billed duration equals six seconds for every attempt and that the exact number of clips is feasible after rounding within each week's shot plan.
Do not consume every credit on week one. Reserve a separate revision envelope for client feedback arriving after the draft delivery. A transparent approach is to hold back, say, 20% of the baseline as a hypothetical planning policy: 1,584 × 0.20 = 316.8, or approximately 317 additional credits. That is not an industry-standard buffer. Your historical revision data should eventually replace it.
Separate calendar risk from production risk
Production risk concerns whether a shot will be accepted. Calendar risk concerns whether it can be generated, reviewed, and edited before its deadline. A crowded delivery week can create rush editing expenses even if AI generations succeed. Put approval dates, not merely publication dates, on the schedule.
For each week define: script lock, source rights clearance, first-pass generation, internal QC, client approval, and platform upload. A missed client approval should not silently trigger repeated generations or a new subscription purchase.
Make a monthly purchase decision only after the forecast
Once the weekly tables are complete, compare the needed credits with the current plan's available balance and rollover rules. If the shortfall lands entirely in the last week, an immediate upgrade may not be economical. If the first week consumes nearly everything, a modest buffer may be justified.
The result is a plan with traceable assumptions, not a promise that every video will be delivered automatically. Estimate each production batch in the calculator, then sum batches by billing period.
Check the source and keep your inputs
Our examples show a decision-making method, not a live price quotation. Before purchasing credits, verify the provider’s billing method and current plan rules in its official credit documentation or the equivalent official page for the tool you use. Keep your calculations reproducible with our total cost CSV worksheet. See the methods and sources page for limitations and a full cost ledger.
