To calculate the total cost of a shift, there are a combination of factors that Rotaready takes into account:
Hours worked (accounting for rest breaks where applicable)
Sanitisation (if the actual start/finish time is available)
Employee's pay record
Pay rules (such as applying an overtime rate after a certain time of day)
Local taxes (such as national insurance)
Holiday pay (either direct or the result of holiday smoothing)
Pension contributions (default 3% for UK businesses)
Other internal wage uplifts found on pay records (such as additional healthcare benefit costs, if applied)
Where to see wage costs
Wage costs are saved at various stages of the lifecycle of a rota (such as when it's published or when sign-off occurs) so they can be referenced later.
Rota editor - enabling the Hours/wages tool shows live wage costs per individual and day, derived from the shifts on the rota as it stands. Attendance isn't taken into account here, as the rota editor is designed for forward planning rather than historical analysis.
Labour breakdown report - a view of actual wage costs split per individual per day.
Rota progress report - a view of forecast wage costs across multiple sites/departments, taken from a snapshot when the rota is marked for approval or published.
Sign-off report - a consolidated view of both forecast and actual wage costs. Forecast is taken from a snapshot when the rota is published. Actual is taken from when sign-off was completed.
Payroll export report - a view of hours and wage costs, exclusively using signed-off data.
How wages are calculated
It's best illustrated by walking through an example scenario. This one's based in a pub in the UK:
John's basic pay is £8.50 per hour
There's a pay rule in place that means he earns a different pay rate, £10.70 per hour, when working in the Kitchen
He has a holiday allowance set to accrue based on the hours he works
He has a 3% wage uplift (representing other benefits this company happens to apply)
The rest break policy grants a 30 min unpaid break for shifts of 8 hours or longer
Here's an example rota, displayed in tabular form:
Let's assume these shifts haven't been worked yet, so there's no clock-ins or clock-outs to worry about.
Basic pay = £327.35
Bar - 7.5 + 5 + 6.5 = 19 hours on the bar @ £8.50 per hour = £161.50
Kitchen - 8 + 7.5 = 15.5 hours in the kitchen @ £10.70 per hour = £165.85
Holiday pay = £39.51
Using the default accrual rate of 12.07%
£327.35 x 12.07% = £39.51
Taxes = £28.87
Using the UK's employer's national insurance rate of 15.05%, applied to anything above the first £175 in any given week
(£327.35 + £39.51 - £175) x 15.05% = £28.87
Pension contribution = £7.41
Using the UK's statutory 3% of net pay (basic pay + holiday pay) for weekly earnings between £120 - £967
(£327.35 + £39.51 - £120) x 3% = £7.41
Wage uplift = £11.00
In this case 3% of net pay (basic pay + holiday pay)
(£327.35 + £39.51) x 3% = £11.00
TOTAL= £327.35 + £39.51 + £28.87 + £7.41 + £11.00 = £414.14
If this example was more complicated and attendance events were available, the hours used to calculate net pay in the first step of the process would have been adjusted as per your organisation's sanitisation rules.
