What is the ratio for an overrun?

The term "overrun" can refer to different contexts, such as project management, manufacturing, or finance, and the ratio can vary accordingly. In project management, an overrun ratio often compares the actual cost to the budgeted cost, expressed as a percentage. For example, if a project has a budget of $100,000 and the actual cost is $120,000, the overrun ratio would be 120%. In manufacturing, it may refer to the amount produced beyond the planned output, but the specific ratio would depend on the details of the production goals and actual results.
