Complete Reiatsu GP Calculator

Welcome to my * step guide on how to calculate the cost of your desired GP points faster than humanly possible. This calculator calculates your total spent AND the amount of GP needed to reach your specified Reiatsu limit. 

1. Open Excel.
2. Label Row 1
   1. A1 should be Current
   2. B1 should be Desired
3. Fill in Row 2
   1. A2 should contain your current Reiatsu, INCLUDING the starting 50. Don't worry, it has been factored in aleady.
   2. B2 should contain your desired TOTAL Reiatsu.
4. Here's where it gets tricky.
   1. In A3, copy and paste the following function: 
      
      SPOILER: Click to show
      =IF(AND(A2>50,A2<200),(A2-50)*15,IF(AND(A2<=200,A2<250),(A2-200)*30+2250,IF(AND(A2<=250,A2<300),(A2-250)*45+2750,IF(AND(A2<=300,A2<400),(A2-300)*60+6000,IF(AND(A2<=400,A2<500),(A2-400)*80+12000,IF(A2>=500,(A2-500)*100+20000))))))
   2. In B3, copy and paste the following function:
      
      SPOILER: Click to show
      =IF(AND(B2>50,B2<200),(B2-50)*15,IF(AND(B2<=200,B2<250),(B2-200)*30+2250,IF(AND(B2<=250,B2<300),(B2-250)*45+2750,IF(AND(B2<=300,B2<400),(B2-300)*60+6000,IF(AND(B2<=400,B2<500),(B2-400)*80+12000,IF(B2>=500,(B2-500)*100+20000))))))-A3
5. Profit.

B3 is the total amount of GP you need to achieve the total Reiatsu score specified in B2. This takes into account starting Reiatsu and the changes of GP cost. Feel free to compare with the chart specified in Stats and Skills before use.

If there's any questions why I did this... A love of Excel and boredom yield weird outcomes.
