TCTM07APPX1 - Calculation of entitlement: The rates and how to use them

Appendix 1 - The rates and how to use them

Note: At points in the calculation when the legislation does not require the numbers to be rounded the calculations display numbers only to 3 decimal places (dp). This is for presentational ease and does not affect the remainder of the calculation. As a result there may be occasion when your own calculation may vary slightly to the award, however this will be rare and due only to the rounding applied by the computer system. For most cases the 3 figure (dp) number will be used in the rounding but occasionally the last figure displayed will show a zero, for example 1.120. An assumption is therefore made that there are further numbers after the 0, (eg.1.1201) which when rounding up will result in 1.13. In these cases only, the rounding is shown as 1.120 = 1.13.
