This is only an estimate. It draws on Flexera's 2025 State of the Cloud report. The report found that organizations waste 27% of cloud spend. It also found that 84% of orgs struggle to manage cloud spend. CostMon shows you where your spend goes. It does not guarantee savings. We never take a cut of what you save. This estimate leaves out one of the biggest levers. Check the commitment discount calculator to see how much a Savings Plan or Reserved Instance could add. If you run Kubernetes, idle capacity hides differently there. See the Kubernetes cost allocation & idle capacity calculator.
One flat price. Read-only access.
CostMon charges a flat rate, not a cut of what you spend or save. Access is read-only, so nothing you connect can be changed from our side.
