Fathom Layer / Cloud versus local
Pay per token.
Or build the capacity.
Estimate when local hardware could recover its upfront cost, using your token volume, cloud API rates and monthly local running costs. Compare the assumptions before making a purchase.
Upfront cost.
Recurring consequences.
Cost arithmetic in USD.
Not a purchasing recommendation.
Upfront hardware cost divided by $400.00 in modeled monthly net savings, assuming all entered API use is replaced.
- Cloud API / month
- $400.00
- Local operation / month
- $0.00
- Monthly cost difference
- $400.00
- Upfront hardware
- $5,800.00
Projected cumulative cost
| Month | Cloud API | Local operation | Cloud minus local |
|---|---|---|---|
| 0 / Upfront | $0.00 | $5,800.00 | −$5,800.00 |
| 6 months | $2,400.00 | $5,800.00 | −$3,400.00 |
| 12 months | $4,800.00 | $5,800.00 | −$1,000.00 |
| 24 months | $9,600.00 | $5,800.00 | $3,800.00 |
Positive cloud-minus-local values mean local operation is less expensive in this scenario. Negative values mean cloud is less expensive. This does not establish workload equivalence.
Taxes, financing, residual value and migration costs are excluded unless included in your amounts. Recorded API conditions may differ from the billing rules that apply to your workload.
Modeled break-even 14.5 months.

Payback needs
more than arithmetic.
Compare upfront hardware spending with recurring API and local operating costs. This is a simplified cost scenario, not a purchase recommendation or a full financial model.
- Cloud costs: Monthly input and output token volumes multiplied by the selected model's recorded rates. Check the linked provider pricing for cache, batch, context and other conditions.
- Local costs: Your upfront hardware budget plus recurring electricity, hosting, maintenance and operator time. Preset budgets are examples, not product quotes.
- Estimated payback: Hardware cost divided by monthly API cost minus monthly local cost. If local running costs meet or exceed the API cost replaced, there is no cost break-even under these assumptions.
- Workload equivalence: The calculation assumes all entered API usage can be replaced locally. It does not establish equivalent quality, speed, uptime or model capabilities.
