Here are the figures from (1) the GlantzĀ“s book and (2) the Soviet General Staff.
(1) Glantz and House. The Battle of Kursk, p 151-152, 275, 414:
Given the attrition of the penetration battle, by 10 July the II SS Panzer Corps' strength had fallen to fewer than 300 tanks and assault guns, and Army Detachment Kempf's III Panzer Corps numbered fewer than 200. On the Soviet side, General P.A. Rotmistrov's 5th Guards Tank Army eventually controlled five corps totaling 830 tanks and self-propelled guns. ...[A]bout 572 [German and Soviet AFVs] met on the field of Prokhorovka itself. (Note: Calculated as 172 tanks and assault guns of Leibstandarte and Das Reich and just over 400 tanks and self-propelled guns of Rotmistrov's 2d, 18th, and 29th Tank Corps.)
...
German armor losses in Citadel are more difficult to pin down.... Considering repaired armored vehicles, these figures indicate that [iI SS Panzer Corps] lost between 60 and 70 tanks on 12 July (at Prokhorovka).... (Note: Finally, during the battle for Prokhorovka, the 5th Guards Tank Army lost over 400 of its 840 tanks and self-propelled guns....)
(2) The Soviet General Staff. The Battle for Kursk, 1943 (originally published in 1944), p 222, 228:
[German units attacking toward Prokhorovka] consisted of three SS Panzer Corps divisions (Adolf Hitler, Death's Head, and Das Reich), 17th Panzer Division units, and also the 168th Infantry Division. This grouping numbered more than 600 tanks, including more than 100 heavy tanks ('Tigers') and self-propelled 'Ferdinand' guns.
...
By the beginning of combat operations the 2d Guards Tatsinskaia Tank Corps and the 2d Tank Corps, which had a total of no more than 200 tanks...were subordinated to the 5th Guards Tank Army.... Thus the 5th Guards Tank Army had 793 tanks, including 501 T-34 tanks, 261 T-70s, and 31 'Churchills', and therefore, with respect to the number of tanks, the correlation of forces was approximately equal, although the enemy had qualitative superiority, especially in heavy tanks and self-propelled 'Ferdinand' guns.
...
As a result of five days of combat, the Germans lost around 300 tanks [and] 20 self-propelled guns....
