Table Breakdown: Percentage Increase Calculations
| Situation | Formula | Example |
|---|---|---|
| Sales growth | (New sales – Original sales) / Original sales x 100% | $1,500 sales increase from $5,000 to $6,500: (6,500 – 5,000) / 5,000 x 100% = 30% increase |
| Investment return | (New investment value – Original investment value) / Original investment value x 100% | $500 increase in investment from $1,000 to $1,500: (1,500 – 1,000) / 1,000 x 100% = 50% increase |
| Population growth | (New population – Original population) / Original population x 100% | 100 people population growth from 1,000 to 1,100: (1,100 – 1,000) / 1,000 x 100% = 10% increase |
