Your workplace regularly takes your pension payments from your earnings and pays them into now:pensions. How much you pay depends on how your workplace calculates your pension payments.
Many workplaces use qualifying earnings. These are all your earnings between a lower and upper limit set by the government and reviewed each year. They include salary, wages, commission, bonuses, overtime, statutory sick pay and statutory parental leave pay (maternity, paternity and adoption pay).
The minimum legal requirement for auto enrolment pensions is 8% of qualifying earnings. Workplaces must pay at least 3% of this. So you pay the remaining 5%. If your workplace pays more than 3%, you pay less. For example, if your workplace pays 4% of qualifying earnings, you pay 4%.
Some workplaces use a different definition of pensionable earnings – the earnings that count towards pension payments. Ask your workplace how they work out pension payments and how much you pay.
