Sources and limits

Capital allocation = (purchase + components − residual value) / months. Electricity = (load W × load hours + idle W × idle hours) / 1000 × electricity price. Curve: cloud hours equal load hours; additional costs stay constant. The current monthly calculation uses entered idle and billed hours. Powered-off consumption is assumed zero. Quality and throughput must match the same workload. No current provider quote; zero API values indicate no modeled API usage.
