Batch vs Realtime LLM Cost
Compare batch API (50% off) vs real-time pricing.
50 is 1.0% of 5,000.
Batch API
Anthropic Message Batches: 50% off, 24-hour SLA. OpenAI Batch: 50% off. For non-realtime jobs (embeddings, summarization, classification), batch is the default — no UX trade-off.
Worked Example
50% of $5,000
- base
- 5000
- rate
- 50
- Result
- $2,500
$5,000 × 50% = $2,500.

Frequently Asked Questions
How is the percentage computed?
(Batch Discount / Realtime Cost) × 100. The result tells you what fraction of the Realtime Cost the Batch Discount represents. For inverse questions ("what's X% of Y?"), swap the inputs accordingly.
What if my percentage is over 100%?
Means Batch Discount exceeds Realtime Cost. Common in growth calculations (sales doubled → 200%) or ratios where the "part" can legitimately exceed the "base." If unexpected, double-check your inputs.
Should I round the result?
For reporting: round to 1 decimal place (e.g., "23.4%"). For internal calculations: keep full precision. Conversion rates and engagement metrics conventionally show 2 decimals (e.g., "3.42% CTR").
What's a meaningful percentage in my context?
Depends on the metric. Conversion rate: 1–5% typical for SaaS landing pages. Engagement rate: 3–6% for mid-tier influencers. Tax rate: federal effective is 12–22% for most middle-class earners. Compare to industry benchmarks to interpret your number.
