How do i work out the % difference?

Question

Say for example last May i earnt £2000 and this May i earn £2857 there would be a difference of £857 how do i work out the % increase or if it was the opposite way round the % decrease.

Many thanks

Answer 1

simple divide £857 by £2000 times 100
This equals 42.85 % more (you lucky bugger)

Answer 2

% increase - (857/2000) x 100% = 42.85% (exact value)
% decrease - (857/2857) x 100% = 30.0% (to 3 sig fig)

You always divide the difference by the original amount as that would represent 100%.

In the first case, 100% is £2000 while in the second, 100% is £2857.

Answer 3

to find the % difference, divide the difference into the first value

increase = 857 / 2000 = 42.85 %

otherwise, if your first value was 2857 and then became 2000

decrease = 857 / 2857 = 30 %

Answer 4

2000+857=2857
857/2000 positive
2000-857=1143
a 42.85% difference

Answer 5

It couldn't be dollars? Anyway...
It's actually pretty simple. 2000 is 100 percent. and 2857 is x percent.
Cross multiply like this: 2000------ 100
2857------ x
Multiply 2857 by 100, then divide by 2000 to find x, the percentage. Then you just subtract as appropriate: x-100, fr the percentage increase.
If it's opposite: 2000----- x
2857------- 100
Then 100-x to find the percentage decrease.
If x is higher, do the opposite.

Answer 6

A percentage change is calculated by dividing the amount of the change by the original amount, then multiplying by 100.

So you would have 857/2000 x 100 % = 42.85% increase

Answer 7

% increase. 857/2000*100=42.85
% decrease 857/2857*100=30 ish
