• Locate the gross monthly salary within the table corresponding to the “lower limit” and “upper limit”.
• Subtract the “lower limit” value from the total income. The result you get will be the base.
• Locate the rate corresponding to the gross salary range in the table.
• Calculate the percentage of the rate to base that you obtained previously.
• Add the fixed fee located in the table to the result.
