Which one do you need?
- LLM API Token Cost Calculator
- Estimate LLM API spend from input and output token counts and per-million pricing, including prompt-cache discounts, per request, per month and per year.
- LLM Cost Per User Per Month Calculator
- Work out what one active user costs you in LLM tokens each month, what gross margin your price leaves, and the price a target margin requires.
- Self-Hosted LLM vs API Break-Even Calculator
- Find the monthly token volume where renting GPUs beats paying per token, including the utilisation assumption that usually decides the answer.
- Prompt Caching Savings Calculator
- Work out what caching a long system prompt actually saves once the write premium, the discounted read rate and the number of cache hits are counted.
- LLM Throughput & Latency Calculator (Tokens Per Second)
- Estimate tokens per second, time to first token and total response time from GPU memory bandwidth and model size, with batching and efficiency.
