Cost Optimization Masterclass — ₩77,000 →

가격 기준: 2026-04 Anthropic 공개 가격. Optimized 시나리오는 80% Haiku / 15% Sonnet / 5% Opus 라우팅 + 5분 캐시(80% 히트) + Batch 50% 가정. 실제 결과는 워크로드에 따라 달라질 수 있습니다.

How to use this calculator

  1. Pick your model. Most teams default to Sonnet — try Haiku to see what 80% routing would save.
  2. Estimate token volume. If unknown, 2000 input / 500 output is a rough Claude API average.
  3. Cacheable tokens. System prompts, schemas, few-shot examples, and RAG context are typically cacheable.
  4. Cache mode + hit rate. 5-minute cache for chat, 1-hour for stable knowledge. 70-90% hit rate is realistic with proper prompt structure.
  5. Batch API. Check this if workload is async (≤24h SLA). 50% off everything.

Frequently Asked Questions

How accurate is this calculator?

Pricing reflects public Anthropic API rates as of April 2026. The Optimized scenario assumes 80% Haiku / 15% Sonnet / 5% Opus routing, 5-minute prompt caching at 80% hit rate, and Batch API for 50% of traffic. Real workload savings vary — these are best-case approximations.

What is the 80/15/5 model routing rule?

Route 80% of work to Haiku, 15% to Sonnet, 5% to Opus. Typical bill reduction: 60-75% versus Sonnet-everywhere. See Haiku vs Sonnet vs Opus.

Does Batch API affect quality?

No. Same models, same quality. Trade-off is up-to-24h latency for 50% discount. See Batch API guide.

Why is my actual bill higher than this estimate?

Common reasons: (1) you're not actually caching cacheable tokens, (2) tool use adds tokens not modeled here, (3) retries on rate limits, (4) max_tokens not set so responses run long. The Cost Optimization Masterclass walks through diagnosing each.

Want to actually implement these savings?

The Cost Optimization Masterclass is a 120-page PDF + 6-sheet Excel calculator (more granular than this page) + 12 production case studies. Real result documented: $2,100/month → $187/month (91% savings) on a customer support agent.
