What should I compare besides bank pay?
At a 5% full-salary contribution, the larger salary also puts £1,250.00 more into your pension each year before employer funding. Employer pension matching, travel costs, working hours and benefits can change the value of an offer. A lower loan deduction improves today’s cash flow but is not automatically a lifetime saving.
Does the higher tax band apply to everything?
Only the slice in each Income Tax band gets that rate. The difference above is calculated separately for each salary, including NI and any selected loan or pension. If your income goes above £100,000, Personal Allowance reductions can also affect the result.
What if I am a Scottish taxpayer?
With no pension or loan, the same rise adds £1,104.17 a month under Scottish Income Tax. Use the comparison tool with your tax region and actual deductions for a personal estimate.
