a rule of thumb at the place I work is just to take the take off weight and minus only flight fuel to get estimated landing weight. Ie for weight purposes plan that taxi fuel, instrument approach fuel, variable Reserve will not be used.
in reality some of those allowances will be used in full (or in part) so the estimate is conservative. Works fine.
