Diagnosis
You have created an overlapping grading.

Example:
Sales From,,,,,,Sales To,,,,,,% Rate,,,,,,Amount,,,,,,Grading Name
0,,,,,,1,000,000,,,,,, ,,,,,,20,000,,,,,,Grading that starts with 0
0,,,,,,3,000,000,,,,,,6%,,,,,, ,,,,,,Grading that starts with 0
2,000,000,,,,,,5,000,000,,,,,,7%,,,,,, ,,,,,,Overlapping grading
5,000,000,,,,,,0,,,,,,8%,,,,,, ,,,,,,Interval grading
In this case, the sales-based rent is determined as follows:
a) Sales = 900,000. The sales are completely within the first grading:sales-based rent = 20,000.
b) Sales = 7,000,000. The sales are distributed over several gradings:
(7,000,000 - 5,000,000,,= 2,000,000),, * 8%,,= 160,000remainder = 5,000,000
+ (5,000,000 - 2,000,000,,= 3,000,000),, * 7%,,= 210,000remainder = 2,000,000
+ (2,000,000 - 0,,= 2,000,000),, * 6%,,= 120,000remainder = 0
sales-based rent,,,,,, = 490,000
c) Sales = 2,500,000. The sales are completely within the secondgrading. The grading above it is ignored. The total sales are calculatedwith 6%: Sales-based rent = 150,000.
