What is the difference between fortnightly amount and fortnightly deduction?

The fortnightly amount refers to the total amount of money that is received or paid out on a fortnightly basis. This could be a salary, rent, loan repayment, or any other regular payment that occurs every two weeks.

On the other hand, fortnightly deduction refers to a specific amount of money that is subtracted or taken out of the total fortnightly amount for a particular purpose. This could be taxes, insurance premiums, loan repayments, or any other deductions that are required to be paid regularly. So, while the fortnightly amount is the total sum of money being received or paid, the fortnightly deduction is a specific portion of that amount that is being subtracted for a specific purpose.
