Salary increase due to inflation: negotiation argument

How inflation influences your argument for a salary increase

In 2025, inflation still plays a key role in negotiating your salary. Between the rise in the cost of living and stagnant incomes, you need to play the card of economic reality to convince your employer. Most employees forget that their purchasing power is directly affected by these developments.

Here is how you can structure your approach :

• Remind them of the steady rise in energy and food prices, which eats into your budget each month.
• Highlight the impact of this inflation on your standard of living, citing concrete examples.
• Insist on the need for a salary adjustment to maintain your purchasing power.
• Compare your salary to previous years, a necessary revaluation operation.
• Use the salary indexation clause, if your contract or collective agreement provides for this mechanism.

Key figures to support your request for an inflation-related raise

In 2025, according to recent studies, inflation is around 2.5%. That means the cost of living has increased by that proportion over one year. For example, if your salary has not been adjusted accordingly, your purchasing power has decreased by at least 2.5%.

For better understanding, here is a comparative table of the main expense categories :

Type of expense	Average increase in %	Annual impact in € for a family
Energy	4.2%	1500 €
Food	3.8%	1200 €
Transport	2.9%	800 €
Housing	2.7%	1800 €
Leisure and others	2.3%	500 €

In total, the typical family must face an increase in its expenses of about 5 800 € per year, partly offset by a moderate rise in wages, unless you negotiate. This is where the indexation clause comes in, which would allow your salary to be adjusted automatically to keep pace with inflation.

Concrete strategies to assert your purchasing power

1. Specify that your salary has not kept up with the rise in prices in recent months.
2. Support your argument with precise figures from your market or the collective bargaining agreement.
3. Highlight your contribution to the company, emphasizing that this increase is a necessary rebalancing.
4. Propose an increase based on inflation: often between 3% and 4% in the current context.
5. Also negotiate other benefits: bonuses, meal vouchers, flexibility, to compensate for a possible refusal.

The stakes of collective bargaining in the face of inflation

Collective negotiations play a major role in managing wage indexation. In 2025, many companies have signed agreements to revalue salary scales according to the cost of living. In this context, social dialogue becomes a strategic tool to enforce the indexation clause.

Appointing a union representative or creating a works council makes it possible to weigh in collectively. This prevents the rise in prices from being borne solely by the employee and promotes a coherent salary rebalancing.

Points to check during a collective negotiation on inflation

• Check whether the collective agreement provides for an automatic indexation clause.
• Discuss the frequency of salary updates.
• Obtain a guarantee that the agreement will be applied in practice.
• Negotiate the creation of an inflation bonus to compensate for rising prices.
• Propose an adaptability mechanism to avoid any slippage during periods of high inflation.

Pitfalls to avoid when negotiating on inflation

Counterproductive, the argument of simply “recovering” lost purchasing power can backfire on you. Here are some common mistakes to be aware of :

• Not preparing a quantified file to justify the desired amount.
• Demanding an increase of more than 4% without solid arguments.
• Relying on a purely emotional speech, without illustrating with concrete examples.
• Failing to refer to the indexation clause if it exists.
• Jumping straight to the demand without negotiating the overall economic context.

Example of failure to avoid: a poorly argued request

Imagine an employee who simply claims that “their salary is too low because they need a raise”. Without figures, without market references or inflation data, the request will quickly be dismissed by the employer.

The benefits of a successful negotiation during a period of inflation

A skillful and well-prepared negotiation allows you to capitalize on the economic situation to obtain :

• A revaluation that covers the rise in the cost of living.
• Better protection against the degradation of your purchasing power.
• Recognition of your skills in the face of economic challenges.
• Salary stability in the face of market fluctuations.
• Increased motivation to continue performing.

To illustrate this, here is a comparative table of purchasing power before and after negotiation in a situation of correct indexation :

Year	Initial salary	Annual inflation	Adjusted salary	Change in purchasing power
2024	35 000 €	2.2%	35 770 €	0%
2025	35 770 €	2.5%	36 570 €	+2.5%

A genuine adjustment strategy makes it possible to preserve your standard of living in the face of the continuous rise in prices.
