AI Training Budget Calculator
Estimate the total budget required to train an AI model from compute and data costs.
About AI Training Budget Calculator
A realistic AI training budget covers more than raw GPU-hours: total = gpu_cost + storage_cost + overhead(15%), where gpu_cost = hourly_rate × gpu_count × training_hours, storage_cost = storage_GB × price_per_GB_month × months (for datasets, checkpoints, and logs), and a 15% overhead buffer accounts for failed/restarted runs, hyperparameter search, evaluation passes, and miscellaneous cloud fees (networking, snapshotting) that aren't captured in the raw compute and storage line items. Budgeting with this buffer up front avoids underestimating real project cost, which commonly runs 10-20% over the 'pure compute' estimate.

total_cost = (gpu_rate * gpu_count * hours + storage_GB * price_per_GB_mo * months) * 1.15

Assumptions and limits
- The result is derived only from the 6 inputs listed above. Anything not among them is not part of the calculation.
- In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
- Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
Frequently Asked Questions
Why include a 15% overhead buffer?
Real training projects rarely go perfectly on the first attempt — failed runs, hyperparameter sweeps, evaluation passes, and incidental cloud costs (data egress, snapshots, idle time between runs) typically add 10-20% on top of the 'ideal' compute and storage cost, so 15% is a reasonable planning buffer.
Does storage cost include checkpoints as well as the dataset?
It should — factor in your dataset size plus periodic model checkpoints (which can be substantial for large models saved multiple times during training) and any logs or intermediate artifacts you plan to retain for the storage duration.
How do spot/preemptible GPU instances change this estimate?
Spot instances can cut GPU cost by 50-70% compared to on-demand pricing, but introduce risk of interruption requiring checkpoint/resume logic — if using spot instances, consider using a lower effective hourly rate and possibly increasing the overhead buffer to account for interruption-related re-runs.
Should training hours include failed/restarted runs?
It's best to estimate training hours for a single successful run and let the 15% overhead buffer absorb typical retry costs; if you expect substantial iteration (e.g. many hyperparameter trials), multiply training hours by your expected number of runs instead.
