The Practical Project Estimation 2nd edition provides a table of regression equations that you can use to obtain an indicative estimate of speed of delivery (FP per elapsed month) for a project. Equations are provided for:

• Development platform
• Development language
• Development language/platform combination

The Toolkit also provides tables for mainframe and mid-range platforms that show speed of delivery by team size. These tables can be useful to establish the practicality, or otherwise, of adding more people to a development team, also in initially planning a practical team size to deliver a required number of function points per month. For example if you have a mainframe project of 900FP which needs to be completed in four months, you need to deliver 225FP per elapsed month. Reference to the appropriate chart indicates a team size of 15-20 people. You can then decide on the practicality of that team size for your project and adjust the project variables as needed.
