# Class 1 structural overview: earnings limits & thresholds for pay intervals of other than a week

## Lower and upper earnings limits - regulation 11(2), SS(C)R 2001

If an employee’s Earnings period (see NIM01003) is for a period other than a week, the appropriate limits may be calculated as follows:

 Earnings Period How to calculate the earnings limits Multiple of a week Multiply the weekly LEL and UEL by the number of weeks in the period. A month multiply the weekly LEL and UEL by 4 1/3 and round the resultant figure up to the next whole pound Multiple of a month multiply the weekly LEL and UEL by 4 1/3 and then by the number of months in the earnings period. Round this answer up to the next whole pound. A year multiply the weekly LEL and UEL by 4 1/3 and then by 12. Round this answer up to the next whole pound Not a multiple of a week or month divide the weekly LEL and UEL by 7. Multiply the answers by the number of days in the period. Calculate to the nearest penny, with a halfpenny or less being disregarded.

## Primary & secondary thresholds - regulations 11(3), SS(C)R 2001

If an employee’s Earnings period (see NIM01003) is for a period of other than a week, the appropriate threshold may be calculated as follows:

 Earnings Period How to calculate the Primary and Secondary Thresholds Multiple of a week Divide the yearly threshold by 52 and multiply the result by the number of weeks in the period. Round this answer up to the next whole pound. Multiple of a month Divide the yearly threshold by 12 and multiply the result by the number of months in the period. Round this answer up to the next whole pound. Not a multiple of a week or month Divide the threshold by 365 and multiply the result by the number of days in the period. Calculate to the nearest penny, with a halfpenny or less being disregarded.
