What Is a Ratio Calculator?
A Ratio Calculator is a tool used to compare two quantities by showing their relationship in ratio form. A ratio expresses how much of one value exists relative to another.
For example, if two values are 20 and 10, the ratio is written as 20:10, which can be simplified to 2:1.
This calculator helps you:
- Calculate ratios accurately
- Simplify ratios to lowest terms
- Understand proportional relationships
Ratios are widely used in mathematics, finance, business analysis, cooking, engineering, and data comparison. To understand the mathematical concept behind ratios, you can also read the explanation on Wikipedia.

Ratio Formula Explained
The Ratio Calculator follows a simple mathematical concept.
Basic Ratio Formula
Ratio = A : B
Where:
- A = First value
- B = Second value
Simplified Ratio
To simplify a ratio, both numbers are divided by their greatest common divisor (GCD).
Example Calculation
If the values are 50 and 100:
Ratio = 50 : 100
Simplified ratio = 1 : 2
Financial Example Using $
If two departments spend $2,000 and $1,000:
Ratio = 2000 : 1000
Simplified ratio = 2 : 1
This shows the first department spends twice as much as the second.
