Promotion pay comparison
Promotion Calculator
Compare current pay with a promotion salary and estimate the extra take-home pay after tax. Use the result to judge the financial effect of a promotion without drifting into generic career advice.
The figures on this page are planning estimates. They are designed to help interpret salary movement, not replace an employer payslip, HMRC, IRS, payroll software or personal tax advice.

After-tax difference
This looks like a useful increase, but the monthly figure is the one to compare with real bills, savings and housing costs.
How to read this page
A promotion can bring more responsibility, different benefits, bonus potential or higher deductions. The first financial test is simple: how much extra monthly take-home pay does the new salary create?
| Step | What to compare | Why it matters |
|---|---|---|
| Current salary | Estimate current take-home pay. | This is the baseline before the raise. |
| New salary | Estimate take-home pay after the increase. | This shows the practical change. |
| Monthly difference | Compare the net monthly gain. | This is usually the number that affects budgeting. |
Promotion pay is not just the headline salary
A promotion may change pension contributions, retirement saving, bonus eligibility, health benefits, commuting cost or tax band exposure. The calculator isolates the salary effect first.
Use the monthly result for real decisions
The net monthly difference is the number that affects housing, childcare, transport, debt repayment and savings capacity.
When the promotion is worth a second look
If the after-tax gain is small relative to extra hours, commuting or benefit changes, the salary number may not tell the full story. That is a planning issue, not a motivational slogan.
Practical examples
| Example | What it shows | Planning takeaway |
|---|---|---|
| Role uplift | New salary, similar deductions. | Focus on net monthly increase. |
| Promotion with benefits change | Salary rises but benefits or deductions change too. | Use the calculator as a baseline, then check payroll details. |
| Promotion into higher-income territory | New salary crosses a tax threshold. | Review tax bands and planning assumptions before judging the offer. |
UK and US planning context
| Context | What can affect the increase | Useful route |
|---|---|---|
| UK salary increase | Income Tax, National Insurance, pension contributions, student loans, salary sacrifice and tax code changes. | UK salary after tax |
| US salary increase | Federal tax, FICA, state tax, filing status, benefits, retirement contributions and withholding. | US salary after tax |
| High-income raise | Tax thresholds, phase-outs, state tax and planning choices can make the retained share less intuitive. | Six-figure salary planning |

Promotion Calculator FAQ
Can this calculator tell me whether to accept a promotion?
No. It estimates the salary effect after tax. Workload, hours, career direction and personal priorities are outside the calculator.
Why might a promotion feel smaller than expected?
Tax, payroll deductions, benefits, commute costs or higher savings contributions can reduce the practical monthly gain.
Should I include bonuses?
Use this page for base salary. If the promotion includes bonus potential, compare it separately with bonus-tax guidance.
Is the result exact?
No. It is a planning estimate. Real payroll may differ.
Bottom line
A salary increase is most useful when it is translated into after-tax monthly income and then compared with real commitments. Use the calculator or guide as a decision baseline, then check actual payroll details before relying on the result.
