How the calculation works

A salary-growth projection repeatedly applies one annual percentage to the previous year’s salary. It illustrates compounding in a gross salary scenario, with a year-by-year table so the difference from a fixed cash increase is visible.

Salary after n years = starting salary × (1 + annual change/100)^n.

  1. Start from year zero

    Record the current annual salary before any increase. A zero-year horizon returns this same amount without applying the rate.

  2. Apply each annual change to the latest salary

    Multiply by one plus the percentage divided by one hundred. The second change applies to the already-adjusted amount rather than the original salary.

  3. Inspect the path and final salary

    The table and chart show each annual value through the selected horizon. The headline is the annual salary rate at that point, not cumulative earnings over all years.

Worked example: Two increases

Sample inputs demonstrate the method. They are not a forecast or product offer.

The first example starts at €40,000 and applies two increases of 10%. Year one becomes €44,000; another 10% on that amount produces €48,400. The second increase is €4,400 because its base has already increased.

Understanding your result

With a positive rate, each later cash increase is larger because the base salary has grown. A constant cash rise would require a different model.

This projection does not forecast promotions, employer decisions or job changes. It also does not subtract inflation or payroll deductions, so nominal gross growth is not a purchasing-power or take-home forecast.

Questions you might have

What does this salary growth calculator include?

Project gross salary over a chosen number of years with an explicit annual pay-change assumption.

Which assumptions should I check?

This is a constant-rate scenario. Promotions, inflation, tax, job changes and employer decisions are not forecast.

Choosing the right inputs

Starting annual salary
Enter the starting annual gross salary. This is the year-zero amount before any projected annual changes.
Annual salary change
Use the annual percentage change to repeat. Negative values represent reductions, and negative 100% reduces salary to zero from the first projected change.
Years to project
Enter a whole number of years from zero to 100. This model does not prorate part of a year or schedule increases on particular payroll dates.

Common mistakes to avoid

  • Do not multiply the annual percentage by the number of years and apply it once; that omits compounding.
  • The final annual salary must not be read as the total salary earned throughout the projection.

Assumptions to check

  • This is a constant-rate scenario. Promotions, inflation, tax, job changes and employer decisions are not forecast.
