A salary increase can be expressed as an amount or a percentage. Knowing both makes compensation offers easier to compare.

The Bethemesh salary increase calculator calculates the new salary, increase amount and corresponding percentage.

Salary increase formulas

New salary = Current salary × (1 + increase / 100)

At €3,000 per month with a 5% raise:

3,000 × 1.05 = €3,150

That is €150 more per month, or €1,800 over twelve months.

To find the percentage between two salaries:

Increase (%) = (New salary − Old salary) / Old salary × 100

Moving from €3,000 to €3,300 is therefore a 10% increase.

Target salary

Entering your current and desired salary is useful when preparing a negotiation because it gives the exact percentage change required.

Monthly and annual pay

Always compare compensation over the same period. Use the hourly, monthly and annual salary calculator for time-period conversion.

Gross or net?

The raise calculation works with either gross or net amounts as long as you use the same basis for both values. Use the gross/net salary calculator separately when needed.

Key point

A 5% raise means the new salary is 105% of the old salary. To find the percentage between two amounts, divide their difference by the starting salary.
