How much is your legacy system costing you?

Keeping an old system alive has visible costs and others nobody measures: incidents, hours of your best people and the risk of knowledge walking out the door. Calculate it in 2 minutes with numbers you already know.

Calculate your yearly cost

Use approximate values: we are after an order of magnitude, not exact accounting.

Reference estimate based on the values you entered. The assessment delivers the real numbers over your actual code and processes.

How it is calculated

Maintenance

Monthly maintenance hours × cost per hour × 12 months. The visible cost on your payroll.

Incidents

Incidents per quarter × downtime hours × cost per downtime hour × 4. The cost the business pays, not IT.

Knowledge risk

If the system depends on 1 or 2 people, we apply a premium on the total: the expected cost of losing that knowledge.
