COMMON QUESTIONS

Frequently asked questions

What is salary sacrifice?

It is an arrangement where contractual cash pay is reduced in return for a non-cash benefit such as an employer pension contribution. Scheme rules and eligibility matter.

Does this include employer National Insurance savings?

No. The calculator focuses on employee take-home and employee deductions and does not assume an employer passes any employer-side saving into the pension.

Can salary sacrifice affect other benefits?

It can affect calculations linked to contractual or reference salary. Employers may use a notional pre-sacrifice salary for some benefits, so check your scheme.

Is this financial advice?

No. It is an estimate for comparing scenarios. Pension tax rules, annual allowances and individual circumstances can require professional advice.
