GPU calculator
Self-host vs API break-even calculator
Self-host vs API break-even calculator is built for teams deciding whether to rent a GPU for an open model or keep paying per-token API. Use it to decide the monthly token volume where a flat GPU rental beats linear API pricing. Keep the workload assumptions consistent across options, then inspect the cited prices and last-checked dates before committing budget.

The decision this page helps you make
Find the monthly token volume where renting a GPU to self-host an open model beats paying per-token API pricing, with one-GPU capacity and a labeled throughput band.
The practical question is the monthly token volume where a flat GPU rental beats linear API pricing. Use the same workload assumptions for every option so the comparison reflects billing differences instead of different inputs.
Start with these inputs
- Self-host: Flat monthly GPU rental and throughput.
- API: Your provider's per-token rate.
- Output: Break-even tokens/month and one-GPU capacity.
What the result includes
| Area | What ByteCosts shows |
|---|---|
| Self-host | Flat monthly GPU rental and throughput |
| API | Your provider's per-token rate |
| Output | Break-even tokens/month and one-GPU capacity |
How to use the result
- Run a realistic base case and a heavier-usage case before choosing a provider or plan.
- Compare alternatives with identical traffic, token, seat, runtime, and retry assumptions.
- Open the cited provider source before a purchase or production billing decision.
Formula
monthlyCost = usageVolume * unitCost, adjusted only for the billing units and optional inputs that this calculator exposes.
Assumptions
- Published rates come from committed ByteCosts datasets or visible source-backed rows.
- Calculator outputs are planning estimates, not final invoices.
- Taxes, negotiated discounts, billing minimums, and undocumented limits are excluded unless the page states otherwise.
- Unknown inputs stay unknown until the user supplies them or a source-backed value is available.
Example scenario
Enter a conservative base case, then duplicate it and change one important driver such as usage, retries, utilization, or output volume. Comparing controlled scenarios makes the result easier to explain and audit.
Interpretation guide
- Compare alternatives with identical workload assumptions.
- Stress-test the input that is most likely to grow in production.
- Verify source links and last-checked dates before making a purchase decision.
Limitations
Self-host vs API break-even calculator is a planning tool, not a billing guarantee. It uses the visible assumptions and committed source-backed data available at the page's last update.
Check the cited provider page and your own production logs before signing a contract, changing price, or committing infrastructure spend.
Frequently asked questions
What should I enter first in Self-host vs API break-even calculator?
Start with self-host: flat monthly gpu rental and throughput. Add optional adjustments only after the base case is understandable.
Is the result a guaranteed invoice forecast?
No. It is a planning estimate based on the visible workload assumptions and source-backed public prices. Taxes, negotiated discounts, undocumented limits, and production behavior can change the final invoice.
Where do the prices and assumptions come from?
ByteCosts keeps provider source links, confidence information, and last-checked dates attached to pricing records. User-entered workload assumptions remain separate from published vendor facts.
