Percentage Decrease Calculator

Enter values to compute.

Original Value v1

New Value v2

Understanding the Math

The Percentage Decrease Calculator computes the result using fundamental principles of mathematics. Calculate the percentage decrease from one value to another.

Formula Definition

Result = ((v1 - v2) ÷ v1) × 100

This formula is applied directly to the inputs provided above. Ensure all units are consistent (e.g., all lengths in meters) before calculation to guarantee accuracy.

Example Problem

Given:

Original Value = 13
New Value = 6

Solution:

Substitute values into the formula:

Result = ((13 - 6) ÷ 13) × 100

Quick Notes

Double-check input units. Inconsistent units (e.g. feet vs meters) will yield incorrect results.
Calculations are performed with high-precision floating point arithmetic.
