Subscription waste detection
Subscription waste detection identifies software subscriptions, SaaS tools, and recurring services that are unused, underused, or redundant. It quantifies the value of subscriptions that could be cancelled, downgraded, or consolidated to reduce operating costs without affecting productivity.

What is subscription waste detection?
Subscription waste detection systematically reviews all recurring software and service subscriptions to identify those that deliver insufficient value. Waste takes several forms: completely unused licences where no one has logged in for 90 or more days, underused subscriptions where the organisation pays for premium tiers but only uses basic features, and redundant tools where multiple teams pay for overlapping products that serve the same function.
Research consistently shows that organisations waste 25% to 35% of their SaaS spend. As the average company now uses hundreds of software tools, the total waste can reach significant sums. Detection requires combining payment data with usage data, which is why many organisations only discover waste during deliberate audits rather than through routine monitoring.
How to measure subscription waste
Subscription Waste Rate = (Value of Unused or Underused Subscriptions / Total Subscription Spend) x 100
For example, if the organisation spends 1.2 million pounds annually on SaaS subscriptions and an audit reveals 300,000 pounds in unused licences, low-usage premium tiers, and redundant tools, the waste rate is 25%. Define utilisation thresholds for each category: a project management tool with fewer than 5 active users out of 50 licences is underused, while a security tool with passive monitoring may show low login activity but still deliver value.
How to reduce subscription waste
Establish a SaaS management process that tracks every subscription with its owner, cost, renewal date, and usage data. Conduct quarterly reviews where low-utilisation subscriptions are flagged for cancellation or downgrade. Require business justification for new subscriptions that overlap with existing tools. Implement automated alerts when subscription utilisation drops below threshold. Right-size licence counts at renewal rather than automatically renewing at the same level. Consolidate overlapping tools by standardising on a single platform for each function.

Recurring Spend Analysis
Financial Metrics
Metric Definition
Recurring spend analysis identifies and tracks all subscription, contract, and regularly scheduled payments to provide a clear picture of committed expenditure. It reveals the true baseline cost of operating the business and surfaces renewal dates, auto-renewal risks, and opportunities to renegotiate or eliminate recurring charges.
Savings Identification Rate
Financial MetricsMetric Definition
Savings Identification Rate = (Value of Identified Savings / Total Addressable Spend) x 100
Savings identification rate measures the value of cost savings opportunities discovered by the finance or procurement team as a percentage of total addressable spend. It quantifies how effectively the organisation is finding opportunities to reduce costs, independent of whether those savings are ultimately realised.
Expense per Employee
Operating cost efficiency per head
Financial MetricsMetric Definition
Expense per Employee = Total Operating Expenses / Number of Employees
Expense per employee measures the total operating expenses of a business divided by its headcount. It is a normalised efficiency metric that reveals how much it costs to support each employee and whether the organisation is achieving operating leverage as it grows. A declining expense per employee (in real terms) signals that the business is scaling efficiently.
