Cost and budget calculators
Calculators that take your own rates and your own volumes and give you a number you can defend — every price is a field you type, so nothing here goes stale and nothing here is anyone else's guess at what you pay.
LLM Cost Calculator
Put one workload against three rate cards and see the monthly bill for each, split into fresh input, cached input and output.
Token Cost Estimator From Pasted Text
Paste the text you are about to send, set your rate per 1M tokens, and get the cost of one request and of a thousand.
Monthly AI Bill Forecaster
Users, requests per user and tokens per request turned into next month's bill, a quiet-month floor, a busy-month ceiling and a twelve-month projection.
Two-Option Cost Comparison
Two rate cards, each with its own fixed monthly fee, against one workload — with the request volume at which they cross over.
Prompt Caching Savings Calculator
Cacheable prefix, hit rate and three separate rates — ordinary, cache read and cache write — turned into a monthly saving and a break-even hit rate.
Batch Discount Savings Calculator
How much of your workload can tolerate an asynchronous window, what the discount on it is worth per month, and what one hour of that wait is worth.
RAG Cost Calculator
Embedding the corpus, storing the vectors, embedding each query and generating each answer, added up into one fully loaded cost per query.
Fine-Tuning Cost Estimator
Data preparation, training runs and monthly serving costed together, and compared against prompting the base model with a longer prompt.
Self-Host vs API Break-Even Calculator
GPU rental, ops time and real utilisation against per-token API spend, solved for the monthly request volume at which running your own box starts to win.
GPU Cost per Million Tokens
Rental or purchase, power and facility overhead divided by the tokens a GPU actually produces, with the cost per 1M shown across six utilisation levels.
Embedding Cost Calculator
Turn a corpus size and a chunking strategy into the one-time index cost, the monthly cost of new documents and queries, and the cost of the re-index you will eventually do.
Vector Storage Cost Calculator
Vectors × dimensions × bytes per component, plus the HNSW graph and the metadata, into gigabytes and a monthly bill.
Agent Run Cost Estimator
Prices a multi-step agent run including the context it resends on every step, at your mean step count and at your p90.
Reasoning Token Cost Estimator
What hidden thinking tokens add to a bill, what turning effort down would save, and what share of the invoice is text you never see.
Image Generation Cost Calculator
Three quality tiers, your per-image prices, and the regenerations nobody counts, into a monthly image budget.
Image Input Token Cost Calculator
Enter an image's width and height and see what it costs as input tokens under three different tiling formulas at once.
Audio Transcription Cost Calculator
Hours of audio at your per-minute rate, with per-request minimums, trimmable silence and the LLM that reads the transcript afterwards.
Text-to-Speech Cost Calculator
Characters into dollars, with SSML markup counted or not counted, an audio cache for your fixed phrases, and retakes billed in full.
Cost per User Calculator
What one user costs you a month in inference — the typical one, the heavy one, and the blended average that hides the difference.
AI Feature Margin Calculator
Price, payment fees, inference and infrastructure into a gross margin — on a typical user, on a heavy user, and blended.
Break-Even Price Calculator for an AI Product
Works out the lowest price per user that covers your inference, your fixed costs and the payment fee — and what a heavy user does to it.
Model Cascade Savings Calculator
Prices cheap-first routing against sending everything to the expensive model, and gives the escalation rate at which the saving disappears.
Context Trimming Savings Calculator
Turns a prompt reduction into a monthly figure, including the case where trimming the prefix costs you the cache discount.
Output Length Cost Impact
Shows what shortening the answer is worth per month, and what 100 extra output tokens on every request cost you.
Retry and Failover Cost Calculator
Expected attempts under your retry policy, what the failures cost, and how much you spend on requests that never produce an answer.
Free-Tier Runway Calculator
Compounds your usage growth against an allowance and says how many days are left, for a one-off credit or one that resets.
Token Budget Planner
Works backwards from a monthly cost ceiling to the prompt you can afford on every request.
Cost Anomaly Detector
Paste a usage export and it groups by day, compares each day against the median and flags the outliers.
Usage CSV Analyser
Paste a usage export, pick any column, and get spend per group with shares and cost per request.
Invoice Reconciler
Compares an invoice total against your own logged usage, with credits and tax, and tells you which direction the gap runs.
Currency Converter for AI Spend
Convert a dollar-denominated AI invoice or rate card into your own currency at the rate you were actually charged, with the date and the card markup shown.
VAT and Reverse-Charge Calculator
Work out the VAT to self-account for on a cross-border AI invoice under the reverse charge, at a rate you enter, including the part you cannot deduct.
Cost Split by Feature
Paste tagged usage and get spend per feature, ranked, with each one's share of the total.
Annual Commitment Break-Even
Model a committed-spend agreement against on-demand pricing month by month, including the months you pay the floor without using it.
Multi-Currency Team Budget Planner
Per-seat licences and per-token usage in one monthly budget, with the licence half converted at an exchange rate you supply.
Cost of a Conversation
What a multi-turn chat costs once every turn re-sends the whole transcript, and how much of the bill is history you have already paid for.
Document Processing Cost Estimator
Price a batch of documents through a text-extraction pipeline and through a vision model, and see which route is cheaper at your page count.
Classification Workload Cost Comparison
Compare an LLM, an embedding classifier and a classical model on monthly cost at your volume, with the build effort amortised and the crossover volumes computed.
Migration Cost Estimator
What moving to a different model costs once re-embedding, dual-running two indexes, repeated eval runs and prompt rewriting are all counted — and how long the saving takes to repay it.
Total Cost of Ownership Calculator
Inference, storage, egress, platform, evaluation and engineering time in one monthly figure, with the human share stated as a percentage of the total.
