Estimate the comparative costs of GPT-6 and Gemini 4 easily with our accurate calculator.
Formula
const gpt6Cost = (inputs.tokensPerMonth / 1000000) * inputs.gpt6PricePerMillionTokens + (inputs.promptEngineeringHours * inputs.hourlyRate); const gemini4Cost = (inputs.tokensPerMonth / 1000000) * inputs.gemini4PricePerMillionTokens + (inputs.promptEngineeringHours * inputs.hourlyRate); const difference = gpt6Cost - gemini4Cost; const recommended = inputs.modelPreference === 'Auto-Select' ? (gpt6Cost < gemini4Cost ? 'GPT-6' : 'Gemini 4') : inputs.modelPreference; return { gpt6MonthlyCost: gpt6Cost, gemini4MonthlyCost: gemini4Cost, costDifference: difference, recommendedModel: recommended };Estimated Tokens per Month
