Understanding the distinction between nominal and real income is crucial. Nominal income is the face value of money you earn, such as a salary of $45,000. However, its actual value can change over time due to inflation. Real income adjusts for these price level changes, providing a more accurate measure of purchasing power.<\/p>\n\n\n\n<p>The tool used for this adjustment is the Consumer Price Index (CPI), which tracks the average cost of a standard basket of goods and services. The formula provided, Real Income = Nominal Income \/ CPI, effectively deflates the nominal income to reflect its value in constant base year dollars.<\/p>\n\n\n\n<p><strong>Step 1: Calculate Real Income for 2009<\/strong><\/p>\n\n\n\n<p>First, we calculate the real income for 2009 using the given figures.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Nominal Income (2009): $45,000<\/li>\n\n\n\n<li>CPI (2009): 2.113<\/li>\n\n\n\n<li>Real Income (2009) = $45,000 \/ 2.113 = $21,296.73<br>This means the purchasing power of the $45,000 salary in 2009 was equivalent to $21,296.73 in the CPI&#8217;s base year.<\/li>\n<\/ul>\n\n\n\n<p><strong>Step 2: Calculate Real Income for 2010<\/strong><\/p>\n\n\n\n<p>Next, we perform the same calculation for the year 2010.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Nominal Income (2010): $46,500<\/li>\n\n\n\n<li>CPI (2010): 2.120<\/li>\n\n\n\n<li>Real Income (2010) = $46,500 \/ 2.120 = $21,933.96<br>In 2010, the person&#8217;s purchasing power was equivalent to $21,933.96 in base year dollars.<\/li>\n<\/ul>\n\n\n\n<p><strong>Step 3: Calculate the Change in Real Income<\/strong><\/p>\n\n\n\n<p>Finally, to find the change in purchasing power, we subtract the 2009 real income from the 2010 real income.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Change = Real Income (2010) \u2013 Real Income (2009)<\/li>\n\n\n\n<li>Change = $21,933.96 \u2013 $21,296.73 = $637.23<\/li>\n<\/ul>\n\n\n\n<p>This positive result indicates that the individual\u2019s real income increased by $637.23. Although their nominal income rose by $1,500, a portion of that gain was offset by inflation (the CPI increased from 2.113 to 2.120). Nevertheless, their pay raise was greater than the rate of inflation, resulting in a tangible increase in their ability to purchase goods and services<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/learnexams.com\/blog\/wp-content\/uploads\/2025\/07\/learnexams-banner5-616.jpeg\" alt=\"\" class=\"wp-image-245273\"\/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Real Income = (Nominal income) \/ CPI (as decimal, or CPI\/100)&nbsp; The Correct Answer and Explanation is: Correct Answer Explanation This problem requires the calculation of real income for two different years and the change between them.
