Suppose your salary in 2014 is $40,000. Assuming an annual inflation rate of 8%, what salary do you need to earn in 2018 in order to have the same purchasing power?

To determine the salary needed in 2018 to have the same purchasing power as a $40,000 salary in 2014, considering an annual inflation rate of 8%, we use the formula for compound interest:

\[
\text{Future Salary} = \text{Present Salary} \times (1 + r)^n
\]

Where:
- $ r $ is the annual inflation rate (8% or 0.08)
- $ n $ is the number of years (2018 - 2014 = 4 years)
- Present Salary = $40,000

Now, let's calculate it:

\[
\text{Future Salary} = 40,000 \times (1 + 0.08)^4
\]

Let's compute this value.The salary needed in 2018 to have the same purchasing power as a $40,000 salary in 2014, assuming an 8% annual inflation rate, is approximately $54,419.56.

1. How does a change in inflation rate affect future salary requirements?
2. What would the required salary be if the inflation rate was only 5% instead of 8%?
3. How does compound interest differ from simple interest in calculating inflation impact?
4. How would the purchasing power change if your salary remained the same over those years?
5. How does inflation affect long-term savings and investments?

**Tip:** Always consider inflation when planning your finances for the future, as it erodes the value of money over time.
