What Is the UK Job Offer Comparison Calculator?
Comparing two UK job offers by base salary alone misses a lot — bonus, employer pension contribution, and other benefits can add thousands of pounds a year, and a higher base salary doesn't automatically mean more take-home pay once Income Tax, National Insurance, and student loan repayment (which all rise with a higher salary) are factored in. This calculator compares both offers two ways: total gross package value (everything combined, before tax) and real take-home pay (after everything actually comes out of your payslip), since the offer that wins on paper doesn't always win in your bank account.
Employer pension contributions are kept separate from your own contribution deliberately — the employer's share is real compensation value that doesn't affect your personal tax at all, while your own contribution (modeled here via salary sacrifice) directly reduces your Income Tax, National Insurance, and student loan repayment together.
UK Job Offer Comparison Calculator Formula
Total Package = Gross Salary + Employer Pension + Other Benefits
Take-Home = Gross Salary − Your Pension − Income Tax − NI − Student Loan
How Is the UK Job Offer Comparison Calculator Calculated?
Gross salary combines base pay and target bonus (base × (1 + bonus%)). The employer pension contribution and other benefits are added on top as pure compensation value, since neither reduces your own take-home pay or is taxed as your personal income the way salary is. Take-home pay is then calculated using the same UK PAYE mechanics as the Salary After Tax + Pension + Student Loan Calculator — your own salary sacrifice pension contribution reduces the base for Income Tax, National Insurance, and student loan repayment together, using 2026/27 HMRC figures throughout.
This means the "winning" offer can differ between the two comparisons — a bigger bonus or employer pension contribution can make one offer's total package larger, while a different balance of salary versus pension can make the other offer's actual take-home pay higher, since pension contributions (by design) don't add to your spendable cash now.
UK Job Offer Comparison Calculator Example
Offer A: £55,000 base, 10% target bonus, 5% employer pension, 5% employee pension (salary sacrifice), £2,000 other benefits totals a £65,250 package, taking home about £41,365 after tax (Plan 2 student loan).
Offer B: £60,000 base (a higher headline salary), 5% bonus, 3% employer pension, same 5% employee pension, £1,000 other benefits totals about £65,800 — a slightly larger package than Offer A — and takes home about £42,529, also higher than Offer A on both measures in this example, despite Offer A having the higher bonus percentage and employer pension rate.
How to Use the UK Job Offer Comparison Calculator
Step 1
Enter each offer's base salary, target bonus percentage, employer pension percentage, your own pension contribution percentage, and other benefits.
Step 2
Select the student loan plan that applies to you (used for both offers).
Step 3
Compare total package value and real take-home pay side by side.

Understanding Your Result
The total package figures show each offer's full gross value — useful for understanding your overall compensation, including pension contributions that build long-term wealth even though they don't add to today's spendable income. The take-home figures show what actually lands in your bank account after everything is deducted, which is the number that matters for day-to-day budgeting and affordability decisions.
These two comparisons can point to different winners, and that's not a contradiction — a stronger pension package genuinely adds long-term value even when it reduces current take-home pay, so which comparison matters more depends on your own priorities between cash now and retirement savings later.
Tips
- If two offers are close, ask each employer for their exact pension contribution structure and any other benefits (private healthcare, life insurance) that have real monetary value but aren't part of base salary.
- A bigger employer pension match is effectively free money, similar to a 401(k) match in the US — it's worth weighing seriously even if it doesn't show up in take-home pay.
- Remember that bonus targets aren't guaranteed the way base salary is — if comparing offers with very different bonus structures, consider running the comparison at a conservative (below-target) bonus assumption too.
- If you plan to increase your own pension contribution over time, re-run this calculator with different percentages to see how the take-home comparison shifts.
- Non-financial factors — career growth, company stability, team, location — matter alongside this calculator's numbers, especially when the financial comparison is close.
Common Mistakes
- Comparing offers by base salary alone and ignoring bonus, pension, and benefits differences.
- Treating employer and employee pension contributions as the same thing, when only your own contribution affects your take-home pay.
- Assuming the offer with the bigger total package always has the bigger take-home pay — a higher pension contribution can make total package bigger while take-home stays lower.
- Forgetting that student loan repayments scale with salary, so a bigger raise brings a bigger student loan deduction too.
- Not accounting for the Personal Allowance taper if either offer's total pay approaches or exceeds £100,000.
Frequently Asked Questions
Why do I need to enter pension contributions separately for employer and employee?
Because they have completely different effects — the employer's contribution is compensation value with no effect on your personal tax, while your own contribution (via salary sacrifice) reduces your Income Tax, National Insurance, and student loan repayment.
Which comparison matters more — total package or take-home pay?
It depends on your priorities — total package reflects your full compensation including long-term pension savings, while take-home pay reflects what you can actually spend now. Neither is more "correct" than the other.
What if one offer doesn't have a bonus?
Enter 0% for the bonus field — the calculator handles offers with or without a bonus naturally.
Does this calculator account for the Personal Allowance taper?
Yes — if either offer's adjusted pay (after your own pension contribution) exceeds £100,000, the calculator reduces the Personal Allowance accordingly, exactly as HMRC rules require.
Can I compare offers with different employer pension structures, like a percentage match versus a flat contribution?
Convert a flat contribution to an equivalent percentage of base salary before entering it, or approximate it using the closest percentage that matches the pound amount.
Should I assume I'll hit my full bonus target?
That depends on your confidence in each employer's bonus history and structure — consider running the comparison at both target and a more conservative bonus percentage to see how sensitive the result is.
Does this calculator include benefits like private healthcare or a company car?
Only as a flat pound estimate in the "other benefits" field — some benefits (like a company car) can also create their own separate tax charge (a Benefit in Kind), which isn't modeled here.
What if I'm comparing a UK offer against one from another country?
This calculator only models UK PAYE mechanics — for a cross-country comparison, you'd need to separately calculate take-home pay under each country's own tax system.
Does the student loan plan apply differently to each offer?
No — your student loan plan is a personal circumstance, not something that varies by employer, so the same plan and threshold apply to both offers' take-home calculations.
How accurate is this compared to my actual payslip?
It's a close estimate using current HMRC rates, but your actual payslip may include additional specific deductions (like a company benefit scheme) not modeled here — use this for comparing offers, and check your actual payslip once employed for exact figures.
Can I compare more than two offers?
Run the calculator multiple times, keeping one offer fixed as Offer A and changing Offer B each time to compare against additional options.
Can I share my job offer comparison as an image?
Yes — tap Share and, on supported devices, your result is shared as a branded image card, not just a text link.
