Frequently asked questions

Why is total cost above salary?
Because UK employers also pay employer NI and pension contributions on top of gross salary, and many businesses carry additional per-employee overhead costs.
Can I use this for budget sign-off?
Yes, as a baseline estimator. Use the same assumptions line (tax year, NI rate/threshold, pension basis, overhead rule) across stakeholders.
