Fine Tuning Calculator — calculate fine tuning for tech projects. Formula, specs, and practical notes.
Total monthly cost = (Usage volume × Cost per unit) + Fixed monthly fee
Cost per user = Total monthly cost ÷ Active users
Annual cost = Monthly cost × 12
Worked example: API with 500,000 requests/month at $0.002 per 1,000 requests + $10 fixed fee. Variable cost = 500,000/1,000 × $0.002 = $1.00. Total = $11.00/month = $132/year. At 5,000,000 requests (10× growth): variable = $10.00 + $10 = $20.00/month — costs grow linearly with usage.
