## Caveats

- Public tiered list rates, shared credits cover browsers, sandboxes and desktop VMs. Engine card represents Professional sandbox only; other tier rates retained as raw regimes because freely combining tier-specific rates with any plan would underprice. Professional only permits 10 concurrent sandboxes.
- Features set to null were not verified. No sandbox was purchased or tested; feature/performance statements are documentation claims. Null maximums are unknown unless a cited note explicitly states unlimited.
- A complete monthly bill requires known snapshot/egress/plan limits; do not silently treat missing ancillary charges as free.
- isolation:"shared" tier (process tree in a 4-vCPU VM shared with your own shared sandboxes; cpu<=4, memMb<=2048, default 512) is described as 'cheaper' but has no published separate rate; 'hardened' = dedicated with all outbound blocked. Parked sandboxes (parkAfterMs) keep their concurrency slot and appear to keep billing; only full pause stops billing. Desktop VMs add $0.02/h for the live screen.

## Gotchas

- Public tiered list rates, shared credits cover browsers, sandboxes and desktop VMs. Engine card represents Professional sandbox only; other tier rates retained as raw regimes because freely combining tier-specific rates with any plan would underprice. Professional only permits 10 concurrent sandboxes.
- Features set to null were not verified. No sandbox was purchased or tested; feature/performance statements are documentation claims. Null maximums are unknown unless a cited note explicitly states unlimited.

## Worked workload

4 vCPU / 8 GiB; 50 simultaneous instances × 8 h/day × 22 days = **8,800 instance-hours**, **35,200 vCPU-hours**, **70,400 GiB-hours**. At 30% observed CPU:10,560 active-vCPU-hours only where the meter actually uses utilization. Assume one start/instance/day:1,100starts. Retain50GiB snapshots for a month;100GiB outbound. Active disk capacity was not specified.

Professional compute at 4/8 is $0.1596/h; 8,800h → $1,404.48; with $200 fee and $200 credits the compute bill remains $1,404.48, but C=10 fails C=50. Enterprise published compute subtotal 8,800×(4×.0175+8×.0055)=$1,003.20, plus unknown contracted minimum/fees and egress. Snapshots are free as of Sep 28; after Oct 1, 50−10=40 GB costs $2/month. No feasible all-in self-serve estimate.
