Render Farm Cost per Frame: How to Calculate It Before You Submit
Five farms, five price lists and 300 frames due on Friday: what will the render farm cost per frame, and what will the whole job cost? This guide gives you the formula, the billing units behind each rate and a worked example, using the pricing pages the farms published on 7 November 2026.
Render farm cost per frame is frame time multiplied by a rate, but that rate comes in three different units, so two price lists are rarely comparable at face value.
- Three billing units: CPU farms charge per GHz-hour, GPU farms per OctaneBench-hour (OBh) and remote-machine farms per node-hour. On 7 November 2026 GarageFarm listed $0.004 per OBh at Low priority, RANCH €0.005 and RebusFarm 0.53 cent, while iRender listed $8.20 per hour for one RTX 4090 node.
- Priority moves the rate: GarageFarm charges $0.024 per CPU GHz-hour at Low priority and $0.072 at High, three times as much. RANCH lists GPU rates from €0.005 to €0.010 per OBh across its three tiers.
- Worked example: 300 frames at 12 minutes each on one RTX 4090 come to about $492 at $8.20 an hour. A 4-GPU node at $30 an hour finishes in about 16.7 hours for roughly $500. The inputs are illustrative, not measured.
- Extras: RebusFarm lists upload, download and storage as free, while Fox charges more for RAM above its 64 GB default and for some software. GarageFarm and RANCH quote prices without tax.
- Practical fix: render a stepped sample of frames, multiply by the frame count and leave headroom for retries. For how hourly nodes differ from per-unit billing, read SaaS vs IaaS render farms for VFX. Test first, then submit.

How Do You Calculate Render Farm Cost per Frame?
Multiply the resource a frame uses by the hours it runs and by the farm’s rate. The resource is GHz on CPU nodes, OctaneBench points on farms that bill per OBh, or a single node on farms with a flat hourly price. Multiply that cost per frame by your frame count to get the job total.
The unit matters more than the headline number. A GHz-hour rate and an OBh rate describe different things, and neither tells you how many hours a frame will take on the farm’s hardware. GHz-hour pricing counts clock speed, not how much work each GHz does, so newer cores finish a frame in fewer GHz-hours. OBh pricing tries to even this out through the OctaneBench score, though your renderer may scale differently from Octane on a given card.
What Do Five Render Farms Charge, and What Does the Rate Include?
Each farm publishes its own unit, tiers and inclusions. The table lists the figures shown on their pricing pages on 7 November 2026. Treat it as a snapshot: rates, tiers and trial offers change, so reread the page before you budget.
What Each Farm Charges and Includes
Read from each farm’s own pricing page on 7 November 2026. iRender is listed first, the others in alphabetical order.
| Farm | Billing unit | Rate on the pricing page | Tiers or priority | Included or extra |
|---|---|---|---|---|
| iRender | Node-hour (whole remote machine) | RTX 4090: $8.20 (1 GPU), $15 (2), $30 (4), $52 (8). RTX 5090: $10.80, $20, $38, $62 | One price per node size | iRender lists 10% off when you pay for 3 hours or more at once. You install your own software and plugin versions. |
| Fox Renderfarm | Core-hour (CPU), node-hour (GPU) | Unit price set by tier; check the live page | Five tiers from Ordinary to Diamond, set by cumulative recharge ($500, $2,000, $5,000, $10,000) | Default RAM is 64 GB and larger nodes cost extra. Some software carries extra charges shown at submission. $25 trial. |
| GarageFarm | GHz-hour (CPU), OBh (GPU) | CPU $0.024 / $0.036 / $0.072. GPU $0.004 / $0.006 / $0.012 | Low / Medium / High | Billed by the second for active render time only. Price includes licenses and excludes VAT. $25 trial. |
| RANCH Computing | GHz-hour (CPU), OBh (GPU) | CPU €0.011 to €0.016. GPU €0.005 to €0.010 | Low / Medium / High, with two rates per tier tied to different node limits | Prices exclude tax. €30 trial and bonus credit on larger top-ups. |
| RebusFarm | GHz-hour (CPU), OBh (GPU) | CPU 1.41 cent. GPU 0.53 cent | One rate, with volume discounts on RenderPoint packs (1 RenderPoint = $1.18) | Upload, download and storage free. No minimum turnover. 25 RenderPoint trial. |
The inclusions differ as much as the rates. GarageFarm states that it bills per second for active render time and not for queue time, and that its rate covers licenses. RebusFarm states that upload, download and storage cost nothing. Fox ties its unit price to cumulative recharge, so a studio that tops up often pays less per unit than a new user. RANCH adds extra credit on larger top-ups. iRender prices the whole machine, which suits artists who want to control software and plugin versions.

Why Is the Lowest Rate Not Always the Lowest Render Farm Cost per Frame?
A per-OBh or per-GHz rate only tells you the price of one unit. The bill also depends on how many units your frame consumes, which the node speed and your scene decide. Two farms with the same rate can charge differently for the same frame, and the priority tier you pick changes the rate itself.
Here is a worked example with illustrative inputs, not measurements: a node scoring 1,000 OB and a frame that takes 10 minutes. The table applies each published OBh rate to that same node.
Cost per Frame at Published OBh Rates
Illustrative inputs: a node scoring 1,000 OB and a 10-minute frame. Cost per frame = 1,000 × (10 / 60) × rate.
| Farm and tier | Published OBh rate | Cost per frame | Cost for 300 frames |
|---|---|---|---|
| GarageFarm Low | $0.004 | $0.67 | $200.00 |
| GarageFarm Medium | $0.006 | $1.00 | $300.00 |
| GarageFarm High | $0.012 | $2.00 | $600.00 |
| RANCH Low | €0.005 to €0.006 | €0.83 to €1.00 | €250 to €300 |
| RANCH Medium | €0.007 to €0.008 | €1.17 to €1.33 | €350 to €400 |
| RANCH High | €0.009 to €0.010 | €1.50 to €1.67 | €450 to €500 |
| RebusFarm | 0.53 cent | $0.88 | $265.00 |
Real nodes at each farm score differently, so these rows show how the rate scales with priority, not which farm is cheaper. Moving from Low to High multiplies the cost by three on GarageFarm and by roughly 1.7 to 2 on RANCH. What the higher tier buys is parallelism: GarageFarm raises the node limit per GPU job from 15 to 60, and RANCH lists 40 to 120 GPU cards across its tiers. RANCH amounts are in euros and are not converted.
How Do You Price a Job on an Hourly GPU Node?
On a node-hour farm the cost is the hours the machine runs multiplied by the node price. Estimate the frame time on one GPU, divide by the multi-GPU speedup of the node you plan to rent, and multiply the resulting hours by the hourly price. Benchmark scores and unit rates do not enter the sum.
What Does a 300-Frame Job Cost on 1, 2, 4 and 8 GPUs?
Take illustrative inputs: 300 frames at 12 minutes each on one RTX 4090, which is 60 hours of single-GPU time. iRender lists RTX 4090 nodes at $8.20, $15, $30 and $52 per hour for 1, 2, 4 and 8 cards. With typical speedups of about 1.9×, 3.6× and 6.5× for 2, 4 and 8 cards, the job takes about 60, 31.6, 16.7 and 9.2 hours and costs about $492, $474, $500 and $480.
Multi-GPU buys time, not savings. The cost stays between about $474 and $500 because the hourly price rises roughly in step with the speedup, while the finish moves from two and a half days to nine hours. Speedups vary by renderer and scene, so replace 1.9×, 3.6× and 6.5× with a measurement from your own scene. iRender states that paying for 3 hours or more up front takes 10% off the hourly price, which would bring the 4-GPU run to about $450. RTX 5090 nodes (each card keeps its own 32 GB) are listed at $10.80, $20, $38 and $62 per hour for 1, 2, 4 and 8 cards.
What Happens to Idle Hours on an Hourly Node?
Hourly billing has one sharp edge: a node costs money for every hour it stays on, including the hours you sleep through. Eight idle hours on a single RTX 4090 node come to $65.60 at $8.20 an hour, so shut the machine down once the last frame has been copied out.
What Else Adds to the Bill Besides Render Time?
Beyond render minutes, check four items: extra RAM or software charges, tax, how long the farm keeps your files, and the resolution of the frames you actually submit. Each can move the total by more than a small rate difference does.
RAM and software: Fox sets default RAM at 64 GB, charges more for larger nodes and says some render software carries extra charges shown at submission. GarageFarm states that its price includes license cost.
Tax: GarageFarm lists prices excluding VAT and RANCH shows prices excluding tax, so budget for tax at checkout.
Storage: GarageFarm keeps project data for 28 days after the last completed render, and RebusFarm lists data storing as free.
Resolution: GarageFarm’s FAQ gives a pixel-count rule: a test at one fifth of each dimension costs one twenty-fifth of the full render. Treat that as an upper bound, since 4K frames usually take about 3 to 4.5 times as long as 1080p rather than exactly four times.
How Do You Test the Render Farm Cost per Frame Before Submitting?
Render a sample of frames spread across the sequence, read the cost and scale it by the frame count. Consecutive frames from one shot understate the cost of heavy shots later on. Most farms support this with a free trial and an estimator.
GarageFarm’s FAQ describes a stepped range such as 1to400s20, which renders 20 frames across a 400-frame sequence and returns an estimate for the full range. It adds that frames rendered in the test are not charged again when you render the full range. Fox offers a $25 trial and a cost estimator, RebusFarm provides a cost calculator and an estimation tool, and RANCH offers €30 of trial credit and a cost estimator. For deeper Redshift and Octane pricing, see the Redshift farm guide and the Octane farm guide.
On an hourly node the test is your own: run a short sequence on the rented machine, note the frames per hour and multiply. Keep room for retries and for the hours the machine sits idle while you check results.

FAQ: Render Farm Cost per Frame
How do I calculate render farm cost per frame?
Multiply the resource a frame uses by the hours it runs and by the farm rate. For GHz-hour pricing the resource is the GHz the nodes use, for OBh pricing it is the node OctaneBench score, and for node-hour pricing it is one node. Then multiply the cost per frame by the frame count.
What is an OBh on a render farm?
OBh means OctaneBench-hour. The farm multiplies the OctaneBench score of the GPU nodes working on your job by the hours they render and by a per-OBh rate. The score is a benchmark of GPU speed, so the unit scales the price with how fast the hardware is.
Is the lowest rate always the cheapest frame?
No. A rate is the price of one unit, and your bill also depends on how many units a frame consumes, which the node speed and your scene decide. Priority tier, queue behavior and extras such as RAM or tax change the total as well, so test a few frames.
Do render farms charge for upload, download and storage?
It varies by farm. RebusFarm lists data storing, upload and download as free of charge. GarageFarm charges for active render time only and keeps project data for 28 days after the last completed render. On an hourly node, any hour the machine stays on is billable time.
How accurate is a test render estimate?
It is close when the sample spans the whole sequence and rough when it does not. GarageFarm notes that its calculator shows a best-case time and leaves out queue waiting, so treat any estimate as a floor and keep headroom for retries and heavier shots.
