This is calculated by multiplying 30 x 50 = 1500. Then multiply that result by 0.01 (100%) and that result to £15. This value means that you will be saving £15 from the original cost of £50 which means you will be paying just £35 instead of £50.

What is the percentage increase from X to Y?

For example, you if your landlord sends you a rent increase notice indicating that your rent will increase from $600 to $660 per week the coming year. What will your rent increase percentage be?

To calculate the percentage increase, X will be 600 while Y will be 660 in this case. If you enter the numbers in the calculator below, you will notice that your rent went up by 10%.

The formula for percentage increase is: ((Y-X)/X)*100

What is the percentage decrease from X to Y?

This is the reverse of above formula. So using same sample above assuming this time your rent decreased from £660 to £600. Then the percentage decrease will be about 9.09%. Try this using the calculator below:

Percentage Calculator (% decrease from X to Y?)



The formula for percentage increase is: ((X-Y)/X)*100

X is what percent of Y?

This calculation is finding what the percentage of a given value is off the actual value. A good example is when you go shopping for a product, the market value for that product for instance is £100 but the seller decides to show some generosity by giving you £10 off the price meaning you will be paying just £90. What percentage is £10 to £100?

Percentage Calculator (X what percent of Y)




The formula for this calculation is (X/Y)*100 where X is the discounted value (£10) while Y is the original value (£100). So (10/100)*100 = 10%.
