Pay Raise Calculator explained clearly

Quick answer: Use this calculator to estimate the effect of a pay rise as a percentage or fixed amount.

Core formulaNew pay = current pay + raise amount. Percentage raise = raise amount ÷ current pay × 100.

This is the main rule used by the calculator, written in plain language so you can check the result.

Worked exampleA salary increase from £28,000 to £30,800 is a £2,800 raise, or 10%.

Examples are rounded where needed, so final values may differ slightly from payroll, school, or accounting systems.

How to read itA raise can look different as a gross annual amount, monthly amount, or take-home change. Use the result as a starting point for negotiation or budgeting.

Use the result as a decision aid, then confirm important school, work, or payroll decisions with the official source.

Common mistakes to avoid

Comparing before-tax raise with after-tax spending power
Ignoring inflation
Using different pay frequencies in the same comparison

Methodology

The calculator compares the old and new pay values, calculates the difference, and shows the change as both money and percentage where possible.
