What this tool does
Shows two things at once: the salary needed to keep the same purchasing power as prices rise, and how much today’s salary will be worth in future terms.
How to use it
- Enter your current salary.
- Enter the average annual inflation rate as a percentage.
- Enter the number of years.
- Run it to get both the required salary and the purchasing-power equivalent.
Worked example
A 50,000 salary at 3% over five years needs about 57,964 to hold purchasing power, while today’s salary is worth about 43,130 in five-year terms.
Calculation method
Salary maintaining purchasing power
salary*(1+inflation/100)^yearsPurchasing power of unchanged salary
salary/(1+inflation/100)^yearsFrequently asked questions
- Why are the two numbers different?
- They run in opposite directions. The required salary inflates to future money; the purchasing-power figure discounts the same salary to today’s value. Both use the same rate.
- Where do I get an inflation rate?
- Use the consumer price index growth published by your statistics office or central bank. A historical average is a starting point, not a forecast.
What this tool does not cover
A single rate compounded over time. Differences between spending categories, tax-bracket changes, and promotions or allowance changes are not reflected.
