Aircraft
I was operating my Piper PA-28-180 at ZZZ. Gross weight was 1;875 lbs and balance was within range per the AFM with just myself and 34 gallons of fuel onboard. Wind was calm and outside air temperature was 94 F (34.4 C); altimeter 29.98. Taxiway B was planned as a takeoff abort point. Calculated takeoff distance over a 50 feet obstacle was 2;250 feet.Engine start; taxi and runup were normal; before takeoff checklist was completed. I received clearance and began a takeoff from Runway XXR. RPM and airspeed did not rise as expected. I made a decision to abort the takeoff and pulled power back to idle. After moderate braking the airplane entered the smooth gravel overrun area. After receiving clearance from Tower; I performed a 180 and taxied the aircraft back to the ramp under its own power.Based on my evaluation of a low power condition I flagged the aircraft as unairworthy and turned it over to my A&P for maintenance.
PA-28 pilot reported the RPMs and speed were not rising as expected during takeoff roll resulting in a rejected takeoff and a runway excursion.  ATC was advised and assisted the pilot in returning the aircraft back to the ramp.
