Percentage change
This can also be found as its own calculator. Here it is for comparison. The result of the calculation depends on which way the numbers are. This calculator also works with negative numbers. The first number cannot be zero.
Percentage difference
In this calculation, the average of the numbers is used as the divisor. The result of the calculation is the same regardless of which way the numbers are given. Both numbers must be greater than zero.
Log difference
This calculation is the difference of logarithms of numbers. The result is the same here too regardless of the order of the numbers. Both numbers must be greater than zero.

Inverse proportionality
In inverse proportionality, as the value of one variable increases, the value of the other variable decreases in the same proportion. This can be applied to calculating speed and time, area calculations, resource allocation, calculating the number of employees, and many other practical matters. You can use the calculator on this website to calculate calculations based on inverse proportionality.
Direct Proportionality
In direct proportionality, the relationship between two variables remains the same. This can be applied to pricing, estimating distance and time, image size changes, and many other practical matters. The calculator on the page makes it easy to perform calculations based on direct proportionality.
Percentage calculations without a calculator
Percentage calculations become much easier when we understand that they are multiplication calculations. You can put the numbers to be calculated in a different order. You can also separate the tens and hundreds into their own numbers.
Negative percent
A percentage calculation can easily result in a negative percentage instead of a positive percentage. You can also calculate a percentage from a negative number. The calculation gets a bit strange when you calculate the percentage change using a negative number, but that's not impossible either.
Percentage and percentage point
A percentage means a hundredth and they are used to measure a share of something. The percentage point, on the other hand, is used when comparing percentages to each other or when referring to percentages of certain percentages.
