Percentage increase/decrease calculation

The percentage increase/decrease from old value (Vold) to new value (Vnew) is equal to the old and new values difference divided by the old value times 100%:

percentage increase/decrease = (Vnew - Vold) / Vold × 100%

Example #1

Price percentage increase from old value of $1000 to new value of $1200 is caluclated by:

percentage increase = ($1200 - $1000) / $1000 × 100%

 = 0.2 × 100% = 20%

Example #2

Price percentage decrease from old value of $1000 to new value of $800 is caluclated by:

percentage decrease = ($800 - $1000) / $1000 × 100%

 = -0.2 × 100% = -20%

Difference and final value calculation

The difference d is equal to the initial value V0 times the percentage increase/decrease p divided by 100:

d = V0 × p / 100

The final value V1 is equal to the initial value V0 plus the difference d:

V1 = V0 + d

What are the changes of conditions for? With their assistance, you can understand conditions. How? Certain changes, which will be examined in the following section, enable us to move from a condition to an identical condition or condition impact. Handy utilization of such changes makes it conceivable to construct a chain of proportionate conditions and conditions results with a genuinely basic arrangement as far as a limited condition, which enables you to discover every one of the underlying foundations of the first condition by the foundations of the last condition.
