How to use this calculator
What this calculator does
Budget model fine-tuning using training example volume, token length, epochs, dataset quality work, evaluation and amortized setup investment.
How to use it
Specify labeled training examples, average training tokens, epochs and vendor training rates. Add dataset preparation and independent evaluation expenses, then choose how to spread that upfront investment.
What the result means
Upfront training cost can be small relative to labeling, evaluation and operating the fine-tuned service. Inference savings should be verified rather than assumed.

Actual AI costs depend on provider pricing, model choice, token usage, discounts, caching, retries, batching, tool calls, workflow design, and usage volume.
Scenario guidance
When to use this
Use when evaluating a small specialized fine-tuning project.
Example scenario
A company considers adapting a general language model for a narrow document classification task.
Inputs that usually matter most
- Training examples, tokens, epochs and training rates
- Dataset preparation and independent evaluation
Common mistake to avoid
Do not treat training spend as the total implementation cost or assume fine-tuning guarantees higher accuracy.
How to interpret the result
Compare quality gains and total ongoing costs against prompt or retrieval alternatives.
Educational scenario with editable values; vendor billing rules, quality and service levels can differ.
Formula
The comparison excludes ongoing refreshes, drift monitoring, hosting, data security, failures and recurring finetuned model inference cost unless included in the expected inference savings.
Worked calculation
Fifty thousand 800-token examples trained for three epochs at $3 per million tokens cost $360. Including $500 labels and $1,000 evaluation makes $1,860 upfront, or $155/month over 12 months, less $50/month assumed inference savings.
Frequently Asked Questions
Does this include the cost of serving the fine-tuned model?
No. Ongoing model serving costs are outside this project-cost estimate, except for any explicitly modeled savings.
What does amortization do here?
It divides the upfront project investment across the entered months for planning; it does not change the amount paid initially.
