How we calculated our BMW Salary Sacrifice examples
Each example breaks down the potential savings and costs involved in a salary sacrifice scheme, which includes:
- The amount of income tax saved
This is calculated as a percentage of the monthly lease cost and depends on your income tax band. - National Insurance (NI) savings
For these examples, an employee’s NI rate of 2% was applied to the monthly lease cost. - The Benefit In Kind (BIK) that would be paid
BIK is a tax applied to employees who receive benefits or perks on top of their salary. The current rate of 2% of the P11D price (divided by 12 for a monthly figure) was used. - The employer’s NI contribution to the BIK value
This is calculated at a rate of 13.8% on the BIK value. - The net cost
This represents the overall monthly cost to the employee after all deductions and additions. - Monthly lease cost
We took this figure from the current Octopus Electric Vehicles price.
These calculations provide a starting point for understanding how an electric car salary sacrifice scheme could impact your monthly outgoings if you were to lease or subscribe to a BMW. They should be used as a guide rather than definitive advice, and it is always recommended to consult with an accountant for personalised advice.
