## Overview

The Percentage Decrease Calculator is a straightforward utility designed to find the exact drop rate between an original value and a new, lower value. Whether you are tracking price reductions, weight loss, or a decline in support tickets, this tool instantly computes both the absolute decrease amount and the percentage drop, allowing you to customize the decimal precision of your results.

## Inputs

- **Original Value** (text): e.g. 150
- **New Value** (text): e.g. 120
- **Decimal Places** (number)

## When to use

- When you need to calculate the exact percentage drop in sales, revenue, or website traffic over a specific period.
- When evaluating price discounts to determine the true percentage saved on a retail item.
- When tracking performance metrics like a reduction in customer support tickets or error rates.

## How it works

- Enter the starting number in the 'Original Value' field.
- Input the lower, updated number in the 'New Value' field.
- Adjust the 'Decimal Places' setting to choose your preferred level of precision (up to 12 decimal places).
- The calculator instantly outputs the absolute decrease amount and the exact percentage decrease in JSON format.

## Use cases

- Retailers calculating the discount percentage of clearance items to print on sale tags.
- Data analysts reporting on month-over-month declines in user churn or server downtime.
- Individuals tracking personal goals, such as calculating the percentage of weight lost or monthly expenses reduced.

## Frequently asked questions

### How is percentage decrease calculated?

It is calculated by subtracting the new value from the original value, dividing that difference by the original value, and multiplying by 100.

### Can I use decimals in the input values?

Yes, you can input both whole numbers and decimals for the original and new values.

### What happens if the new value is higher than the original value?

This tool is designed for decreases. If the new value is higher, the result will be a negative percentage decrease, which actually represents a percentage increase.

### How many decimal places can I display in the result?

You can configure the output to show anywhere from 0 to 12 decimal places using the decimal places setting.

### Does this tool calculate the absolute difference as well?

Yes, the calculator outputs both the percentage decrease and the absolute decrease amount.
