B737900er:
First, establish your most limiting weight for take-off which will be the lowest of:
a) performance RTOW
b) structural RTOW of aircraft
c) landing weight RTOW which = MLW + trip fuel to destination
Take the most limiting of the above and subtract the actual ZFW to give a fuel that can be carried ( + you may add taxi fuel )
Finally ensure that this fuel uplift does not exceed the fuel you actually require for the subsequent sector - no point in "over tankering".
The above technique will always work and save any embarrassment.
