AI API Call Budget Planner
The AI API Call Budget Planner compares your monthly dollar budget against your account's RPM and TPM rate limits to find which one actually caps your usable call volume first. Its burn-down mode projects whether current spending pace will exhaust a budget before the billing period ends, based on spend-to-date and days elapsed.
AI Image Generation Cost Calculator
The AI Image Generation Cost Calculator works out the raw cost of a batch of AI-generated images at your provider's current per-image rate. Its true cost mode accounts for acceptance rate and human review time, showing that the real cost per usable, approved image is often several times higher than the quoted per-generation price.
AI Latency vs Batch Size Calculator
The AI Latency vs Batch Size Calculator works out total request latency and system throughput from TTFT and inter-token latency (TPOT) at a given batch size. Its SLO mode interpolates between two benchmarked batch sizes to find the largest batch size that still keeps total latency within a target maximum, the practical ceiling for how aggressively a serving system can batch requests.

Why 20 Usable Clips Can Take 56 Generations to Produce
Budgeting a video production run purely off "clips needed times per-second rate," with no allowance for failed or rejected generations, is the mistake I see most often. A 90% technical success rate combined with a 40% creative acceptance rate yields a combined yield of only 36%, so a project needing 20 final usable clips at that yield actually requires roughly 56 total generations, not 20, a gap a raw "20 clips times rate" estimate misses entirely. Always separate technical success rate from creative acceptance rate before finalizing a budget, since combining them into one vague buffer number hides which problem is actually driving cost. This shows up most on a project's first few batches, before a team has enough completed runs to know either rate with confidence.
What the AI Video Generation Cost Calculator Actually Does
This tool works out the raw cost of generating video clips at your provider's current per-second rate, and separately, the true cost per usable clip once both technical failures and creative rejections are factored in. According to a 2026 breakdown of AI video API pricing, per-second rates vary enormously by model and resolution tier, from roughly $0.03 per second on value-tier models to $0.75 per second on premium 4K models with native audio, so duration and quality tier together drive cost far more directly than for single-image generation. Cost by duration mode handles a straightforward "seconds times rate times clip count" calculation; true cost mode accounts for two separate loss points, generations that fail technically and generations that complete but get creatively rejected, both of which inflate real cost well above the quoted rate.
Why Video Cost Scales With Both Duration and Resolution
Unlike a flat per-image price, video pricing multiplies rate by clip length, so a small change in resolution or quality tier compounds across every second of every clip. Confirm the exact resolution tier intended for shipping before pricing a project, since the same 2026 breakdown shows a 5x gap between a fast, lower-quality tier and a premium 4K tier from the same provider family, a gap applying to every second of every clip rather than being a one-time difference.
| Rate | 10-Second Clip Cost | 20-Clip Batch Cost |
|---|---|---|
| $0.03/sec (value tier) | $0.30 | $6.00 |
| $0.15/sec (fast tier) | $1.50 | $30.00 |
| $0.75/sec (premium 4K) | $7.50 | $150.00 |
Two Separate Loss Points: Technical Failures and Creative Rejections
Video generation carries a risk simple image generation mostly avoids: a generation can fail technically, timing out or erroring partway through, while still consuming its full billed cost. Work out technical success rate separately from creative acceptance rate, since these are genuinely different problems, one documented case on Adobe's Firefly community forum described credits being charged for a video generation that got stuck and never produced a usable result. Multiply the two rates together, technical success rate times creative acceptance rate, to find the combined share of generations ending up both completed and usable, and track them separately since they call for different fixes: retrying a prompt for creative misses versus checking provider status or input parameters for technical failures.
Estimating a Full Production Batch
Project a full batch by dividing the number of usable clips needed by the combined yield rate to find total generations required, then multiplying by per-clip cost. Isolating the dollar amount lost specifically to technical failures, as opposed to creative rejections, gives a concrete figure worth raising with a provider if it looks unusually high, in line with the workload-level tracking Google Cloud's guidance on video generation cost optimization recommends over estimating in aggregate. Set separate generation-count and cost targets for each clip type in a mixed project, since a batch combining short social clips with longer hero footage has meaningfully different true costs per usable clip for each category, and a single blended estimate understates the longer, more expensive category's real budget need.
Accuracy and Limitations
The arithmetic here is exact given accurate duration, rate, success rate, and acceptance rate inputs. This calculator does not track live provider pricing or model availability, and video-generation-specific volatility is real, the same 2026 pricing breakdown documents a major provider confirming the planned removal of an entire video API product line with no successor announced, so always verify a model is still actively supported before basing a production plan on it. Both success rate and acceptance rate are highly project-specific, varying by prompt complexity, clip length, and provider, so use logged outcomes from actual generations rather than a borrowed industry figure, and re-check both rates across a project's early batches specifically, since a rate that looks stable at 10 generations can shift meaningfully at a larger, more representative sample.

How I used the AI Video Generation Cost Calculator to separate a real platform problem from a creative one
A video production team reached out in mid-2025 asking me to help them understand why a batch of 50 AI-generated product demo clips had cost nearly triple their initial estimate of $750, calculated as 50 clips at roughly 10 seconds each and $0.15 per second. Their working theory was that their prompts simply needed to be much more detailed to get usable results, and they were preparing to spend significant time rewriting their entire prompt library before the next batch.
Breaking the true cost down into its two components told a different story. Their creative acceptance rate, the share of completed generations the client actually approved, was a reasonable 55%, not the source of the problem. The real issue was a technical success rate of only 62%, well below what the team had assumed, caused by clips consistently timing out whenever a specific camera-motion parameter was combined with their preferred aspect ratio, a provider-side interaction they had not identified as the cause.
Rather than rewriting their prompt library, the team isolated and removed the specific parameter combination causing timeouts, which brought technical success rate up to 91% on the next batch with no change to creative approach at all. The corrected combined yield reduced total cost for an equivalent 50-clip target by roughly 40% compared to the problem batch, without the weeks of prompt-rewriting work the team had originally planned to invest.
