The initial value cannot be zero, because division by zero is undefined \u2014 the calculator will show an error message if you try it.<\/p>\n<h2>What Is Percentage Increase?<\/h2>\n<p>Percentage increase measures how much a value has grown relative to its starting point, expressed as a percentage of that starting point. Instead of saying \"the price went up by $20,\" you can say \"the price increased by 20%\" \u2014 which immediately tells you the size of the change compared with the original amount.<\/p>\n<p>This makes percentage increase far more informative than an absolute difference. A $20 rise on a $100 item is dramatic; the same $20 rise on a $10,000 item is negligible. The formula divides the change by the initial value precisely to capture this relative scale.<\/p>\n<p>Percentage increase appears everywhere: salary raises, inflation rates, sales growth, population statistics, exam score improvements, and interest earned on savings. Whenever a number goes up and you want to describe the growth in a way that is comparable across different sizes, percentage increase is the standard tool.<\/p>\n<h2>Interpreting the Result<\/h2>\n<ul>\n<li><strong>Positive result<\/strong> \u2014 the final value is larger than the initial value; the number grew by that percentage.<\/li>\n<li><strong>Result of 0%<\/strong> \u2014 the two values are identical; nothing changed.<\/li>\n<li><strong>Negative result<\/strong> \u2014 the final value is smaller than the initial value. This is actually a percentage <em>decrease<\/em>, and you can verify it with the <a href=\"https:\/\/wpcalc.com\/en\/mathematics\/percentage-decrease-calculator\/\">Percentage Decrease Calculator<\/a>.<\/li>\n<\/ul>\n<p>Note that the result is always measured <em>relative to the initial value<\/em>, not the final one. An increase from 100 to 120 is 20%, but going back down from 120 to 100 is a decrease of only about 16.7%, because the reference value changed.<\/p>\n<h2>Assumptions and Limitations<\/h2>\n<ul>\n<li><strong>Zero initial value:<\/strong> the calculation requires a non-zero starting value. If the initial value is 0, any growth from it cannot be expressed as a percentage.<\/li>\n<li><strong>Direction matters:<\/strong> this calculator is designed for growth. If your values usually go down, the <a href=\"https:\/\/wpcalc.com\/en\/mathematics\/percentage-change-calculator\/\">Percentage Change Calculator<\/a> handles both directions with the same input style.<\/li>\n<li><strong>Percentage increase vs. percentage difference:<\/strong> if you need to compare two values without treating either as the starting point, use the <a href=\"https:\/\/wpcalc.com\/en\/mathematics\/percentage-difference-calculator\/\">Percentage Difference Calculator<\/a> instead.<\/li>\n<li><strong>Percentages are not additive:<\/strong> a 20% increase followed by a 20% decrease does not return the original value \u2014 you end up 4% lower. Compound changes require repeated calculations.<\/li>\n<li><strong>Negative values:<\/strong> the calculator accepts them mathematically, but the meaning of a \"percentage increase\" between negative numbers can be counterintuitive. Be careful when interpreting such results.<\/li>\n<\/ul>\n<h2>Quick Reference Table<\/h2>\n<table>\n<thead>\n<tr>\n<th>Initial value<\/th>\n<th>Final value<\/th>\n<th>Absolute change<\/th>\n<th>Percentage increase<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>50<\/td>\n<td>60<\/td>\n<td>10<\/td>\n<td>20%<\/td>\n<\/tr>\n<tr>\n<td>100<\/td>\n<td>120<\/td>\n<td>20<\/td>\n<td>20%<\/td>\n<\/tr>\n<tr>\n<td>200<\/td>\n<td>250<\/td>\n<td>50<\/td>\n<td>25%<\/td>\n<\/tr>\n<tr>\n<td>80<\/td>\n<td>100<\/td>\n<td>20<\/td>\n<td>25%<\/td>\n<\/tr>\n<tr>\n<td>1,000<\/td>\n<td>1,050<\/td>\n<td>50<\/td>\n<td>5%<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>The table shows why percentages matter: a change of 20 means something very different depending on where it started.<\/p>\n<h2>Related Calculators<\/h2>\n<p>To combine several percentage changes into one figure, try the <a href=\"https:\/\/wpcalc.com\/en\/mathematics\/average-percentage-calculator\/\">Average Percentage Calculator<\/a>.
