Observational variable that is utilized for example free variable which is; a. Data Claim, b. Year Sell, c. Supporter data processes. Meanwhile variable is tied-up is cost warrant that computing each month it or Logarithm t is time up to warranty. Acquired data collecting of secondary data via corporate documents, proprietary file corporate. Analisys is data utilizes simple Linear Regression Result of this research points out that exists 4 flour kaolin rates that guaranteed apparently have cost estimation who shall be taken on each type titrates mix's flour kaolin on titrates 2 % cost warrant as big as Rp 2.887.525,26 and WCA'S warranty cost as big as Rp 298.442,84 therefore happening over budgeted (cost plus warrants), to titrate 2,5 % having cost warrants as big as Rp 597.728,39 and WCA Rp warranty cost 100.029,45 (over budgeted), on rate 3 % have warranty cost as big as Rp 158.062,21 and WCA Rp warranty cost 85.066,20 therefore happening over budgeted and on rate 5% have warranty cost as big as Rp 211.821,65 as big as and WCA Rp warranty cost 104.791,02.
