| 1-hour session | ≥ $0.18 (2 vCPU / 4 GB · rank 18 of 28) | ≥ $0.341 (2 vCPU / 4 GB · rank 28 of 28) |
| Fleet month | ≥ $1,589 (50 × 8 h × 22 days) | ≥ $2,999 (50 × 8 h × 22 days) |

| Billing: Plan minimum | $5 a month [1] | $20 a month [2] |
| Billing: Billing increment | unknown (Billed 'for every 10ms' an instance runs; the field holds whole seconds) [1] | unknown (Not published; provisioned memory is billed in '1 minute minimum increments', Active CPU increment not stated) [2] |
| Billing: Minimum charge | unknown (Not published) [1] | 60 s [2] |
| Billing: Per-job fee | None [1] | $0 per job [2] |
