NMWM03140 - National Minimum Wage rates: calculating “fair� piece rates
Relevant legislation
The legislation that applies to this page is as follows:
- National Minimum Wage Regulations 2015, regulations 41 to 43
For pay reference periods starting on or after 1 October 2004, special rules apply to the rated output work system (NMWM07080). Under that system, employers can decide to pay a "fair" piece rate for every piece produced or task performed (rather than pay at least National Minimum Wage for every hour worked) (NMWM03150).
“Fair� piece rates (NMWM03130) are calculated with reference to:
- the average hourly output rate of an average worker (NMWM03150), and
- the worker's assessed hourly rate (NMWM03130) and
- the worker's National Minimum Wage rate (NMWM03010).
Calculating a “fair� piece rate
To calculate a “fair� piece rate divide the worker’s National Minimum Wage hourly rate by the average hourly output rate for the piece or task.
If the pay reference period starts on or after 6 April 2005, multiply the result by 1.2. (This produces a result that is the equivalent of calculating by reference to the worker’s assessed hourly rate (i.e. 120% of the average hourly output rate.)
"Fair" piece rates must be re-calculated whenever National Minimum Wage rates change.
Examples
Pay Reference Periods starting 1 October 2004 until 5 April 2005 (inclusive)
The worker is entitled to National Minimum Wage at the main rate (then £4.85)
- The employer tells you the average hourly output rate = 10 items per hour
- The “fair� piece rate is £4.85 divided by 10 = £0.485 per item
Pay Reference Periods starting on or after 6 April 2005Ìý
The worker is entitled to National Minimum Wage at the main rate (here £5.05)
- The employer tells you the average hourly output rate = 10 items per hour
- The “fair� piece rate is £5.05 divided by 10 multiplied by 1.2 = £0.606 per item
Although not specifically shown in the calculation above, the assessed hourly rate in this example is 8.33 items, (120% of the average hourly output rate, 10 divided by 1.2)
