60 frame batches · equal workers, ideal distribution, 10% overhead
How to use render time calculator
Use a representative per-frame render time to estimate completion. Enter equally capable workers and an overhead allowance for scheduling, transfers, or other work.
- Enter the number of frames still to render. For a partially finished job, use the remaining frames.
- Enter seconds per frame from a test render using the settings and hardware you intend to use.
- Enter the number of equally capable workers that can render separate frames at the same time. Use 1 for a single worker.
- Add a percentage allowance for scheduling, transfers, and other overhead. Review the result as an estimate.
How the calculation works
Estimated seconds = ceil(frames ÷ workers) × seconds per frame × (1 + overhead ÷ 100)
A batch gives each available worker one frame. The number of batches is rounded up because a remaining frame still needs a full per-frame render interval. The overhead allowance increases the complete estimate; it is not a separate fixed setup time.
Worked examples
A short animation on four workers
240 frames at 30 seconds per frame need 60 batches on four equal workers. That is 1,800 seconds, or 30 minutes. Adding 10% overhead gives 1,980 seconds: 33 minutes.
An incomplete final batch
Ten frames on three equal workers need four batches, not 3.33. At 30 seconds per frame and 0% overhead, the estimate is 120 seconds, or two minutes. Only one worker has a frame in the final batch.
| Workers | Frame batches | Duration (H:MM:SS) |
|---|---|---|
| 1 | 240 | 2:12:00 |
| 2 | 120 | 1:06:00 |
| 4 | 60 | 0:33:00 |
| 8 | 30 | 0:16:30 |
What the result means
Whole frame batches are rounded up. Actual speed depends on frame complexity, hardware, memory, and distribution; this is not a cost quote.
Common questions
How should I measure seconds per frame?
Test several representative frames, including a complex part of the sequence. Use the intended resolution, samples, scene, and hardware. Try typical and slower measured values in the calculator to see how the estimate changes. A single unusually simple frame can underestimate the job.
Will twice as many workers finish in half the time?
The calculation assumes equal workers rendering independent frames with ideal distribution. Different hardware, shared resources, uneven frame complexity, or loading delays can change the actual completion time. Small jobs also have a partially filled final batch. Choose an overhead allowance based on your workflow.
Does this estimate the price of a render farm?
This result estimates elapsed render time. A cost quote also needs the provider’s pricing and billing rules. It does not benchmark your scene or account for a provider’s queue.
