Adjust Calculator Width % Adjust Calculator Width: Move the slider to left and right to adjust the calculator width. Note that the Help and Tools panel will be hidden when the calculator is too wide to fit both on the screen. Moving the slider to the left will bring the instructions and tools panel back into view. Also note that some calculators will reformat to accommodate the screen size as you make the calculator wider or narrower. If the calculator is narrow, columns of entry rows will be converted to a vertical entry form, whereas a wider calculator will display columns of entry rows, and the entry fields will be smaller in size ... since they will not need to be "thumb friendly".	Show/Hide Keypads Show/Hide Popup Keypads: Select Show or Hide to show or hide the popup keypad icons located next to numeric entry fields. These are generally only needed for mobile devices that don't have decimal points in their numeric keypads. So if you are on a desktop, you may find the calculator to be more user-friendly and less cluttered without them.	Stick/Unstick Tools Stick/Unstick Tools: Select Stick or Unstick to stick or unstick the help and tools panel. Selecting "Stick" will keep the panel in view while scrolling the calculator vertically. If you find that annoying, select "Unstick" to keep the panel in a stationary position. If the tools panel becomes "Unstuck" on its own, try clicking "Unstick" and then "Stick" to re-stick the panel.

If I don't know what your set up is I have no way to find and fix the issue.

How to calculate percentage change.

How to Calculate Percent Change

The formula used for calculating percent increase or decrease is as follows:

Percentage Change Formula

% Change	=	(	V₂ - V₁	)	100
			V₁

Where V₁ is the starting number and V₂ is the ending number

To see how the percent change formula works, let's suppose you wanted to calculate the percent change in the cost of attending college from the previous year. If the tuition last year was $5,000, and tuition this year is $5,500, here is how you would calculate the percent increase in college tuition:

Calculate Percent Change from 5000 to 5500

% Chg.	=	(	5500 - 5000	)	100
			5000

% Chg.	=	(	500	)	100
			5000

% Chg.

0.10 * 100

Change

10% Increase

On the other hand, let's suppose tuition last year was $5,500, and tuition this year is $5,000 (I know, wishful thinking), here is how you would calculate the percent decrease in college tuition:

Calculate Percent Change from 5500 to 5000

% Chg.	=	(	5000 - 5500	)	100
			5500

% Chg.	=	(	-500	)	100
			5500

% Chg.

-0.0909 * 100

Change

-9.09%, or a 9.09% Decrease

If you are wondering why a 500 increase results in a higher percentage change (10%) than a 500 decrease (9.09%) in the above example, it's because the denominator in the percentage change formula is always greater in the case of a percentage decrease (higher of the two numbers is the divisor).

I hope my explanation has solidified your understanding of how to calculate percent change. If not, please use the feedback form beneath the calculator to let me know what questions I have left unanswered.
