While Company B grew more in absolute dollars ($10M vs $200K), Company A had a higher growth rate (20% vs 10%) </code></pre> <h2>Calculating Percentage Increase</h2> <h3>Step-by-Step Calculation</h3> <p><strong>Step 1: Find the Increase</strong></p> <pre><code>Increase = New Value - Original Value </code></pre> <p><strong>Step 2: Divide by Original Value</strong></p> <pre><code>Relative Increase = Increase ÷ Original Value </code></pre> <p><strong>Step 3: Convert to Percentage</strong></p> <pre><code>Percentage Increase = Relative Increase × 100 </code></pre> <p><strong>Complete Example:</strong></p> <pre><code>Original: 250 New: 325
Step 1: 325 - 250 = 75 (increase) Step 2: 75 ÷ 250 = 0.30 Step 3: 0.30 × 100 = 30%
Answer: 30% increase </code></pre> <h3>Quick Calculation Methods</h3> <p><strong>Method 1: Using Multiplier</strong></p> <pre><code>Percentage Increase = (New Value ÷ Original Value - 1) × 100
Example: 250 → 325 Multiplier = 325 ÷ 250 = 1.30 Percentage Increase = (1.30 - 1) × 100 = 30% </code></pre> <p><strong>Method 2: Decimal Conversion</strong></p> <pre><code>1. Divide increase by original value
- Move decimal two places right for percentage
Example: Increase 75, Original 250 75 ÷ 250 = 0.30
- 30 = 30%

The rate increased by 40%, not 2% </code></pre> <p><strong>When to Use Each:</strong></p> <ul> <li><strong>Percentage Points</strong>: When discussing absolute changes in rates, percentages</li> <li><strong>Percentage Increase</strong>: When discussing relative growth of a value</li> </ul> <h2>Practical Tips</h2> <h3>Calculating Mental Estimates</h3> <p><strong>10% Increase:</strong></p> <pre><code>Move decimal left one place, add to original
10% of 250 = 25 250 + 25 = 275 (10% increase) </code></pre> <p><strong>25% Increase:</strong></p> <pre><code>Find 1/4, add to original
25% of 200 = 50 200 + 50 = 250 (25% increase) </code></pre> <p><strong>50% Increase:</strong></p> <pre><code>Find half, add to original
50% of 180 = 90 180 + 90 = 270 (50% increase) </code></pre> <p><strong>100% Increase (Doubling):</strong></p> <pre><code>New value = original × 2
100% of 150 = 150 150 + 150 = 300 (100% increase) </code></pre> <h3>Checking Your Work</h3> <p><strong>Quick Sanity Check:</strong></p> <pre><code>If new value is 1.5x original: 50% increase If new value is 1.25x original: 25% increase If new value is 2x original: 100% increase If new value is 1.1x original: 10% increase </code></pre> <p><strong>Common Mistakes to Avoid:</strong></p> <ul> <li>Don't confuse percentage increase with percentage points</li> <li>Don't forget to divide by the ORIGINAL value (not new value)</li> <li>Don't mix up absolute increase with percentage increase</li> <li>Remember that 100% increase means doubling, not 100% of original</li> </ul> <h3>How do I calculate percentage increase?</h3> <p>Calculate the difference between new and original values, divide by the original value, then multiply by 100. Formula: [(New Value - Original Value) ÷ Original Value] × 100. Example: From 100 to 120 = (20 ÷ 100) × 100 = 20% increase.</p> <h3>What's the difference between percentage increase and percentage points?</h3> <p>Percentage increase measures relative growth from one value to another. Percentage points measure the absolute difference between two percentages. Example: A rate increasing from 5% to 7% is a 2 percentage point increase, but a 40% percentage increase.</p> <h3>How do I calculate salary increase percentage?</h3> <p>Divide the raise amount by your old salary, then multiply by 100. Example: Old salary $50,000, new salary $55,000. Raise = $5,000. Percentage increase = ($5,000 ÷ $50,000) × 100 = 10% raise.</p> <h3>What does a 100% increase mean?</h3> <p>A 100% increase means the value has doubled (new value is 2x the original). The increase equals the original amount. Example: 100 → 200 = 100% increase (increase of 100, which equals original).</p> <h3>How do I calculate annual growth rate?</h3> <p>For single-year growth, use the standard percentage increase formula. For multi-year average, use: [(Ending Value ÷ Starting Value)^(1/n) - 1] × 100, where n is the number of years.</p> <h3>Is a 10% increase good?</h3> <p>A 10% increase is generally considered healthy growth. For salary raises, 10% is excellent (above the typical 3-5%). For investments, 10% is a strong return. For business revenue, 10% shows solid growth.</p> <h3>What's the difference between percentage increase and growth factor?</h3> <p>Percentage increase expresses growth as a percentage (e.g., 20% increase). Growth factor expresses the multiplier (e.g., 1.2x). A 20% increase equals a 1.2x growth factor. Convert: Growth Factor = 1 + (Percentage Increase ÷ 100).</p> <h3>How do I calculate multiple periods of growth?</h3> <p>For compound growth over multiple periods: Final Value = Original × (1 + rate)^n, where rate is the growth rate as a decimal and n is the number of periods. Example: $100 growing 10% for 3 years = $100 × 1.1³ = $133.10.</p> <h3>Can percentage increase be negative?</h3> <p>No, percentage increase specifically measures growth (positive change). If the new value is lower than the original, it's a "percentage decrease" and the result would be negative if you use the increase formula.</p> <h3>Is this percentage increase calculator free?</h3> <p>Yes, our percentage increase calculator is completely free with unlimited calculations. No registration or payment required.
