Are accelerator-hours the same as elapsed hours?

No. Eight accelerators running for ten elapsed hours equal 80 accelerator-hours.

Can I use a spot or reserved rate?

Yes, if that is the rate appropriate to your scenario; account separately for expected interruptions or reruns.

What should I put in other costs?

Only known costs not already included, such as CPU, memory, networking, egress, orchestration, data preparation, or labeling.

Does the result predict the cost to reach a target accuracy?

No. It prices entered resource time and cannot predict model convergence or quality.

How to Estimate AI Training Cost

Define one run or experiment plan, then use rates and billing boundaries from the infrastructure you will actually use.

Choose a display currency.

Avoid bundled-cost double counting

If an instance rate already includes accelerators, CPU, and memory, use the corresponding effective accelerator allocation once and do not add those same costs again.

What the Training Budget Includes

The calculator measures purchased compute time, not model quality or training progress. It accepts any user-entered accelerator rate and keeps non-compute expenses visible.

960 accelerator-hours cost 3,360; storage and other entered costs add 390.

The model permits zero compute while retaining explicit project costs.

Model reruns explicitly

Increase hours or include expected reruns in the scenario; the calculator does not infer failure or experimentation rates.

Accelerator-Hour Training Cost Formula

The method uses a simple resource-time product so every price assumption remains visible and replaceable.

Formula

accelerator-hours = accelerator count × hours per accelerator

Accelerator-hours

accelerator-hours = accelerator count × hours per accelerator

Compute cost

compute cost = accelerator-hours × hourly rate per accelerator

Total training cost

total cost = compute cost + storage costs + other costs

Scientific Background

Official cloud documentation describes GPUs as attached compute resources and explains that availability and billing depend on configuration and region. Because those prices and bundles change, this calculator stores no provider price table.
