- You are a Basic rate (20%) taxpayer. Your effective rate of tax and National Insurance combined is 19.7%.
- At 37.5 hours a week, £42,500 works out to about £21.79 an hour before tax.
- A 5% salary-sacrifice pension contribution (£2,125) would reduce both Income Tax and National Insurance, so your take-home falls by less than the amount saved.
