Calculating surface water runoff volume

I'm trying to calculate how much water will runoff of a area through a given point.  I have the DEM of my area and the soil data.  I've already delineated the drainage basin that feeds the pour point and created flow direction and flow accumulation, but now I'm stuck trying to combine that data with the soil data.  Obviously not all of the water will flow through the pour point, most will get absorbed by the ground, but I was hoping to get a rough estimate of the runoff volume at the pour point based on a rainfall total of X inches. Thanks
