How to Use a Backwards Percentage Calculator
A BACKWARDS PERCENTAGE CALCULATOR is useful when you need to find the original number before a percentage was applied. Here’s how it works:
Step 1: Identify Your Given Values
Before using a reverse percent calculator, gather the following:
- Final Value (e.g., the price after tax or discount).
- Percentage Change (e.g., 20% discount or 15% tax).
- Increase or Decrease (whether the percentage was added or subtracted).
Step 2: Use the Reverse Percentage Formula
If a percentage was added, use:
Original Value=Final Value/1+Percentage/100
If a percentage was subtracted, use:
Original Value=Final Value/1−Percentage/100
Step 3: Calculate the Original Value
For example, if the final price after a 20% discount is $80, the original price is:
Original Price=80/1−0.20
=80/0.80=100
A reverse discount calculator automates this calculation for quick results.
Common Uses of a Reverse Percentage Calculator
A percentage reverse calculator is helpful in various real-life situations:
- Finding the original price before a discount (e.g., sale price vs. regular price).
- Undoing a percentage increase (e.g., price before tax).
- Determining pre-markup costs (e.g., wholesale price before a 30% markup).
- Calculating salary before deductions (e.g., pay before tax withholdings).
- Reversing percentage-based changes (e.g., percentage losses in stocks).
Whether you’re using a reverse markup calculator for business or a percentage calculator with money for shopping, these tools are incredibly useful.

How to Reverse Calculate a Percentage in Different Scenarios
Scenario 1: Finding the Original Price Before a Discount
- Sale price: $80
- Discount: 20%
- Original price = $80 ÷ 0.80 = $100
Scenario 2: Undoing a Tax Percentage
- Final amount: $115
- Tax rate: 15%
- Pre-tax price = $115 ÷ 1.15 = $100
Scenario 3: Reversing a Percentage Markup
- Final price: $130
- Markup: 30%
- Cost price = $130 ÷ 1.30 = $100
A reverse calculating percentages tool simplifies these calculations.
