Estimated Cost
We calculate the estimated cost of the project using the Basic COCOMO model. For those familiar with the details, we are using coeffcients a=2.4 and b=105.

Estimate seems way too high?
Have you excluded any external dependencies or libraries from your codebase? Ohloh will scan and calculate everything in the enlistment.
You can exclude files and directories on the project enlistment page.
Estimate still seems way off?
Software cost estimation is tricky business even when all the variables are known (which we certainly don't have). One thing to remember is that COCOMO was created to model large institutional projects, which often don't compare well with distributed open-source projects. Beyond just development time, COCOMO is meant to include the design, specification drafting, reviewing and management overhead that goes along with producing quality software.
This model seems to be most accurate with mature, large projects. Young projects with little activity are typically overvalued.
