🔹 Formula
Price Impact (%)=New Price – Old PriceOld Price×100\text{Price Impact (\%)} = \frac{\text{New Price – Old Price}}{\text{Old Price}} \times 100Price Impact (%)=Old PriceNew Price – Old Price×100
And if you want to calculate the financial effect: Impact Value=Price Change×Quantity\text{Impact Value} = \text{Price Change} \times \text{Quantity}Impact Value=Price Change×Quantity
🔹 How to Use the Calculator
- Enter the old price (before change).
- Enter the new price (after change).
- Input the quantity or units affected.
- Click calculate → Get the % impact and the total cost/revenue change.
🔹 Example 1 – Business Pricing
- Old price of product = $20
- New price = $25
- Quantity sold = 1,000 units
Step 1: % Impact 25−2020×100=25%\frac{25 – 20}{20} \times 100 = 25\%2025−20×100=25%
Step 2: Value Impact 5×1000=$5,0005 \times 1000 = \$5,0005×1000=$5,000
👉 A 25% price increase generates an extra $5,000 in revenue.
🔹 Example 2 – Investment Price Change
- Old stock price = $100
- New stock price = $85
- Shares owned = 200
85−100100×100=−15%\frac{85 – 100}{100} \times 100 = -15\%10085−100×100=−15% −15×200=−$3,000-15 \times 200 = -\$3,000−15×200=−$3,000
