Fuel at destination is calculated by the FMC Performance function.  It
uses the cruise altitude, wind profiles, and calculated speed (such as
ECON) to perform the integration.  It uses the lateral flight plan for the
distance and if there are any discontinuities then a direct line distance
between the discontinuous parts are used.  This probably happens most when
you have not entered an arrival.

The biggest impact to the fuel at destination is the accuracy of the wind
model.

If you can be a little more detailed as to what information you need, I
can expand on the explanation.
