For development teams building AI features and needing to understand token costs across different models
Calculate AI model costs based on token usage. Understand how input tokens, cache tokens, and output tokens contribute to monthly expenses, compare pricing across models, and optimize token allocation for cost efficiency.
Input Cost
$30
Cache Cost
$2
Output Cost
$30
Total Monthly Cost
$62
Processing 10M input tokens at $3/M, 5M cache tokens at $0/M, and 2M output tokens at $15/M yields $62 total monthly cost.
AI token pricing varies significantly across models based on parameter count, training methodology, and provider infrastructure costs. Input tokens cost less than output tokens due to computational asymmetry, while prompt caching enables dramatic cost reduction by reusing common context across requests.
Token cost optimization balances model capability against pricing efficiency. Large context windows and prompt caching strategies can reduce effective per-token costs while maintaining quality, particularly for applications with reusable instruction patterns or reference documents.

Understanding token cost composition enables optimization decisions through model selection, prompt engineering, caching strategies, and output length management. Different token types carry varying prices reflecting computational requirements, with output generation typically costing more than input processing due to sequential generation overhead.
Prompt caching provides meaningful cost reduction opportunities for applications with reusable context, reference documents, or consistent instruction patterns. Cache tokens cost substantially less than regular input tokens as cached content bypasses initial processing stages. Organizations often achieve strong savings through strategic cache utilization in customer support systems, documentation Q&A, and structured data analysis where common context repeats across requests.
Token cost optimization requires balancing model capability against pricing efficiency. Smaller models offer lower per-token costs but may require more tokens to achieve equivalent quality, while larger models cost more per token but can deliver results with fewer tokens. Production optimization typically involves measuring actual token consumption patterns, testing model alternatives, implementing prompt compression techniques, and establishing monitoring to detect cost anomalies before they impact budgets significantly.

Output tokens require sequential generation where each token depends on previous outputs, creating computational overhead absent in parallel input processing. Models must maintain context across generation steps, apply sampling strategies, and validate output quality through each token. Input processing benefits from parallel computation across prompt tokens, making it computationally cheaper per token. This pricing asymmetry reflects fundamental differences in generation complexity between reading existing text and creating new text token by token.
Prompt caching stores processed representations of repeated context, eliminating redundant computation for common prompts, system instructions, or reference documents. When cached content appears in subsequent requests, models skip initial processing steps and retrieve pre-computed representations. Applications with consistent instruction patterns, shared knowledge bases, or recurring contextual information can achieve substantial cost reductions. Effective caching requires identifying reusable context portions and structuring prompts to maximize cache hit rates while managing cache invalidation for updated content.
Token consumption varies dramatically by use case, model selection, and implementation approach. Conversational applications typically consume moderate input and output tokens per interaction, document analysis tools process large input volumes with modest outputs, content generation services produce high output volumes from smaller prompts, and code generation balances input context with substantial code outputs. Measure actual production usage rather than relying on estimates, as prompt engineering choices, user behavior patterns, and quality requirements significantly influence consumption. Many applications find actual usage differs from initial projections by meaningful margins.
Model selection involves balancing per-token costs against quality, speed, and total token requirements. Smaller models offer lower per-token prices but may need more tokens or multiple attempts to achieve desired quality, while larger models cost more per token but can deliver results efficiently. Calculate total cost including retry attempts and quality-driven regeneration, not just base per-token pricing. Test target use cases across model options measuring both quality metrics and actual token consumption to identify optimal cost-performance balance for specific requirements.
Output token reduction typically involves specifying concise response formats, implementing length constraints in prompts, using structured output formats like JSON to minimize verbosity, requesting bullet points rather than full paragraphs where appropriate, and designing systems that generate only essential information. Some applications benefit from two-stage approaches where initial requests determine necessary detail level before generating full outputs. Monitor output length distributions to identify opportunities for constraint tuning without sacrificing necessary information completeness.
Budget planning requires measuring current consumption patterns, projecting growth based on user adoption forecasts, incorporating safety margins for usage variability, and establishing cost monitoring with alerting thresholds. Track cost per user or cost per transaction to identify scaling economics and detect anomalies early. Plan for optimization investments that become justified at higher volumes, such as prompt engineering efforts, custom model training, or caching infrastructure. Many organizations benefit from tiered approaches where initial lower volumes accept higher per-token costs before optimization investments make economic sense.
Model pricing changes periodically as providers optimize infrastructure, introduce new capabilities, or adjust market positioning. Monitor provider announcements for pricing updates, maintain flexibility to migrate between models if pricing changes economics significantly, and build cost monitoring that detects unexpected rate increases. Some applications benefit from model abstraction layers that facilitate switching between providers without extensive code changes. Understand whether your provider guarantees pricing stability for specific periods or can change rates with limited notice.
Predict costs through prototype testing with representative prompts and expected usage patterns. Measure token consumption across sample interactions, multiply by projected monthly volumes, and apply appropriate model pricing. Account for variability in prompt lengths and response sizes based on actual use cases rather than averaging. Build cost projections including development phase experimentation, initial lower-efficiency implementation, and optimized steady-state operation. Many teams find actual production costs differ from initial estimates as real user behavior and edge cases emerge during deployment.
