Calculate monthly LLM token costs across prompts, outputs, users, and daily usage before choosing an AI model.
Formula
const inputCost = users * promptsPerUserPerDay * inputTokens * inputCostPerMillion / 1000000 * daysPerMonth; const outputCost = users * promptsPerUserPerDay * outputTokens * outputCostPerMillion / 1000000 * daysPerMonth; const totalMonthlyCost = inputCost + outputCost; const annualCost = totalMonthlyCost * 12; return { inputCost, outputCost, totalMonthlyCost, annualCost };Users
