3 scenarios
$120/month ($1,440/year)
Media Company Archive Processing (500 hours/month, batch)
30,000 minutes at $0.004/min via Dynamic Batch. Add $50-$100/month for Cloud Storage and egress fees. Total: $170-$220/month. This is 92% cheaper than AWS Transcribe standard ($720/month) and 67% cheaper than OpenAI Whisper ($180/month) for the same volume.
$192/month ($2,304/year)
Real-Time Captioning Service (200 hours/month)
12,000 minutes at $0.016/min for standard real-time processing. Add $30-$80/month for GCP infrastructure (Cloud Functions, Pub/Sub, Storage). Total: $222-$272/month. First 60 minutes/month free reduces to 11,940 billable minutes ($191/month).
$4,800/month ($57,600/year)
Enterprise Analytics Platform (5,000 hours/month)
300,000 minutes at $0.016/min standard rate. Enterprise volume pricing (contact sales) may reduce to $0.008-$0.012/min ($2,400-$3,600/month). Add $300-$500/month for BigQuery, Storage, and Cloud Functions. Using Dynamic Batch where real-time is not needed reduces to $1,200/month base.
