Your store manager will take home up to 20% of his salary - and for a store manager I know, that equates to £24,000 - if all targets are met, your deputy will take home up to 10% and your team leaders will take home up to 3% [like colleagues].
Most convenience store managers should expect to clear £6-£7k, providing their KPI's have been met; most main chain store managers should expect to clear £10-11k, providing their KPI's have been met.
