What is the Increment Arrears Calculator?
This calculator finds the arrears due when an increment takes effect from an earlier date than the one it is paid from. Enter the old and new monthly salary and the months of arrears. It shows the monthly difference, the increment per cent and the total arrears owed.
How it works
The monthly difference is the new monthly salary minus the old monthly salary. Total arrears are the monthly difference multiplied by the months of arrears. The increment per cent is the difference divided by the old salary, times 100. A zero old salary shows zero per cent.
How to use it
- Enter the old monthly salary.
- Enter the new monthly salary after the increment.
- Enter the number of months for which the new pay was not yet paid.
- Read the monthly difference and the total arrears.
Increment Arrears Calculator — FAQ
How do I count the months of arrears?
Count the months from the date the increment takes effect to the date the new salary starts being paid. Decimals are fine for part months.
Do arrears include allowances linked to salary?
Only if you enter salaries that include them. Enter the old and new totals your payroll uses for the comparison.
What if the new salary is lower?
The monthly difference and total come out negative, showing a recovery rather than arrears owed.
