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
The raise you keep after tax is the difference between estimated take-home pay at the old salary and estimated take-home pay at the new salary. The retained share is usually lower than the headline raise percentage.
| 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. |
What 'after-tax raise' means
An after-tax raise is the increase in usable pay after income tax, payroll deductions and standard assumptions are applied. It is not the same as the gross salary difference.
Why the retained share varies
The retained share depends on where the extra income lands in the tax bands and whether payroll deductions, state tax, pension, retirement saving or student loans apply.
How to sense-check the output
Compare the estimated monthly raise with the costs it is supposed to cover. A raise can be meaningful even if the percentage retained looks modest.
Practical examples
| Example | What it shows | Planning takeaway |
|---|---|---|
| Gross raise | New salary minus current salary. | Useful for headline comparison. |
| Net raise | New take-home pay minus current take-home pay. | Best for real budget planning. |
| Retained share | Net raise divided by gross raise. | Shows how much of the raise survives deductions. |
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 |

Raise After Tax Calculator FAQ
How much of a raise do I keep after tax?
It depends on your tax bands, payroll deductions, location and benefits. The calculator estimates the retained amount using simplified assumptions.
Does a raise push all my pay into a higher tax band?
No. Tax bands usually apply marginally, meaning only income above a threshold is taxed at the higher rate.
Why does the monthly raise look small?
Annual gross figures can sound large, but after tax and monthly division the practical paycheck change is often more modest.
Can I use this for a percentage raise?
Yes. Enter the current salary and either calculate the new salary externally or type the new salary directly.
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.
