Percentage change (increase or decrease)=(New value -Old value)/(Old value)*100%
If result is positive it is an increase. If result is negative it is decrease
% increase=28.298%=28.30%
Compare the definition above with the inflation measure and decide if they are the same.

SOURCE: Calculating Percent savings

Since I don't use the percent sign. Here is instead a MUCH easier way. Divide the price you bought it for (289) by the original price (648). This gives you the percentage that 289 is with respect to 648 if you just read off the first two decimal places. When you divide one number by another it will tell you how many times they 'fit' for the purpose of explaining it. That is also essentially what a percentage is out of 100 parts. so when you divide one number by another, you will get a decimal answer, just multiply it by 100 (or just take the first two decimals) and that is percent saved (percent different). Note that if the first value is LARGER than the second, you will have a percentage of over 100%.

### How do I calculate percentage of increase

3=100%
26=A (the A is the percentage of the this year)
so we make 26*100=3*A
2600=3A
A=2600/3=866.67 (is the percentage of the this year)
and to know the percentage increase (we remove the percentage of the last year (100%) from the percentage of the this year 866.67%
so we get 866.67-100=766.67
so your percentage increase is 766.67%

### When an amount is increases by 15% it becomes \$117300. Find rthe original amount.

Your problem is that of percentage increase.

To calculate that, this is what you do:

Initial amount (Initial amount * percentage) = Percentage increase.

Let us call the initial amount, x.

Then our parameters are:
Initial amount = x
Percentage = 15/100
Final amount = 117300

So,
x (x * 15/100) = 117300
x (15x/100) = 117300
(x/1) (15x/100) = 117300
(100x 15x)/100 = 117300
115x/100 = 117300

cross multiplying
115x * 1 = 117300 * 100
115x = 11730000

dividing both sides by 115

115x/115 = 11730000/115
x = 102000.

So the original amount was \$ 102000.

Have a wonderful day.

### Increase percentage of 70 to 200

A percentage increase from a value a to a value b is defined as
Percent increase=(b-a)/a*100 percent.
In your case it is (200-70)/70=1.857. Multiply this number by 100 and append the percent symbol. Thus increase=185.7 percent or about 186 percent.
