About this tool
Infrastructure ROI Calculator
The Infrastructure ROI Calculator computes infra-to-revenue ratio, ROI trend, and scaling efficiency from cost and revenue growth rates.
• Track infra cost as percentage of revenue for a quarterly board update
• Model infrastructure ROI improvement from an optimization initiative
• Benchmark infra spend against healthy SaaS ratios
• Calculate when infrastructure costs will require optimization if growth continues

FAQ
What does this tool tell you?
The Infrastructure ROI Calculator computes infra-to-revenue ratio, ROI trend, and scaling efficiency from cost and revenue growth rates.
What affects the result most?
Infrastructure ROI = (revenue_enabled - infra_cost) / infra_cost — return on infrastructure spend. Revenue per server: total_revenue / server_count — rough efficiency metric. Infra cost as % revenue: healthy SaaS is 8-15% of revenue on infrastructure.
How should I use the result?
The calculation is deterministic — the same inputs always produce the same output — so the most useful workflow is to vary one input at a time and see which factor moves the result most. That tells you where to focus your attention before committing to a decision.
