Where the money leaks
Most teams pay for idle or over-provisioned capacity — 20–40%* is typically recoverable.
The biggest line is rarely the one being watched — one lever (caching, routing, or a commitment) usually moves it most.
Without per-team attribution, no one owns the number — showback makes the savings stick.
The cloud layers to optimize

Free calculators — each one explained in plain language, with what to enter and what to do with the result.
🧮 Agent Loop Cost - Multi-Turn Agent Budget with Runaway Risk
This calculator predicts your monthly AI bill while accounting for hidden costs when automated tasks get stuck in loops.
You'll need: Average steps your AI takes per task · Estimated words processed per step · Number of tasks your business runs daily · Risk percentage of the AI getting stuck
What it tells you: Your predictable monthly budget for normal operations · The hidden cost of 'runaway' tasks that loop forever · Comparison of agent costs versus simpler AI methods
What to do with it: Use the typical-case cost to set your monthly department budget · Set 'circuit breaker' limits on steps and spending to stop runaway costs · Decide if a complex agent is worth the price premium over a simpler tool
Watch out: Small errors can snowball; a 1% failure rate can become your biggest expense if you lack hard limits.

🧮 Agentic AI Stack - Full Cost from Tools to Memory
This calculator predicts the total monthly bill for running a team of AI workers that can search the web, remember past conversations, and complete complex tasks.
You'll need: How many daily tasks you want the AI to handle · How many back-and-forth messages each task takes · How many external tools or databases the AI must check · How much information the AI needs to store in its long-term memory
What it tells you: The total monthly cost for the AI brain, memory, and monitoring · A breakdown of hidden fees like tool usage and debugging software · A comparison of costs based on using standard versus premium AI models
What to do with it: Use the total to decide if the AI is cheaper than hiring more staff for the same workload · Check the tool-call cost to see if you need to limit how often the AI searches the web · Allocate a specific budget for 'observability' so you can actually fix the AI when it makes mistakes
Watch out: Don't ignore the monitoring costs; without specialized tracking software, you cannot debug why an agent failed or where money is being wasted.

🧮 Cheapest Model - Best Value for Your Workload
This tool finds the least expensive AI model that is still smart enough to handle your specific business tasks without making mistakes.
You'll need: A 1-10 score of how difficult your task is · The minimum quality level you can accept · How many tasks you run per day
What it tells you: The specific AI model tier that offers you the best value · How much money you save by choosing mid-tier over premium · The monthly cost based on your actual work volume
What to do with it: Use the complexity score to filter out models that are too basic for your needs · Check the quality floor to ensure you aren't sacrificing customer satisfaction for a lower bill · Compare the top three recommendations to see if a slight price increase significantly boosts reliability
Watch out: Never pick a cheaper model that falls below your quality floor just to save money; it will cost more in fixes later.

🧮 Chunking Optimizer - Chunk Size vs Cost vs Recall
This tool helps you decide how to slice your documents so your AI finds the right answers without wasting money.
You'll need: The average length of your documents · How many pieces of information you want the AI to read at once · The type of content you have, like short FAQs or long manuals
What it tells you: The total monthly cost for storing and searching your data · The predicted accuracy of the AI's answers based on slice size · The best size for each text chunk to balance speed and quality
What to do with it: Use smaller slices for simple facts and FAQs to keep costs low and answers precise · Use larger slices for complex manuals to ensure the AI doesn't lose the context of a step · Compare different sizes against a test set of questions to find your business's sweet spot
Watch out: Slicing text too small can save money but make the AI lose the 'big picture' meaning.
