SCP-8640

Expected annual

$10K

One-time setup

$-420195

Annual recurring

$8K

Personnel

One-time investigative expenses (~$80k) are dominated by equipment purchases and field-team labor; recurring annual costs are minimal (~$7.5k) for records and archive maintenance. A large notional containment-cost avoidance (~$500k) is noted because the object self-neutralized.

⚡ Cost Scenarios

📊 Baseline (baseline) $8K/yr

92.0% probability / year

No further field activity; ongoing records maintenance, archive and equipment upkeep only.

no_manifestation no_public_interest

🚨 Minor Incident $14K/yr

6.0% probability / year +$7K vs baseline

A small follow-up investigation or new evidence prompts a single redeployment and limited lab work/legal response.

new_witness_report new_media_or_discovery

🚨 Property Acquisition $108K/yr

2.0% probability / year +$100K vs baseline

Unexpected need to secure or purchase the property for secrecy/permanent control following discovery or recurrence.

📋 Confidence Notes

Line items are drawn from analyst estimates with clear ranges; one-time investigative costs are well-bounded while optional/avoided items (property purchase, containment avoidance) introduce larger uncertainty, hence medium confidence.
