Very little. By one estimate jets burn about 10% of fuel to reach _cruising altitude_. [1] Unless the catapult got you up to altitude it would not help much. Catapults solve a different problem, namely taking off from a short runway.

On the plus side, a catapult that could get the airplane up to cruising altitude in one piece would make for a heck of a ride.
