How to Calculate Percentages - The Basics

Understanding percentages is essential for everyday life, from shopping to business. A percentage represents a portion of 100. For example, 50% means 50 out of 100, or half of something.

Basic percentage formula:

Percentage = (Part / Whole) × 100

For example, if you scored 45 out of 60 on a test: (45 / 60) × 100 = 75%

Our calculator automates these calculations and provides step-by-step breakdowns so you can understand the math behind the results.

UK VAT Calculator - Add and Remove VAT

Value Added Tax (VAT) is a consumption tax applied to most goods and services in the UK. Our VAT calculator supports all UK VAT rates and can both add and remove VAT from amounts.

Current UK VAT Rates (2024):

• 20% (Standard Rate): Applied to most goods and services, including electronics, clothing, and professional services
• 5% (Reduced Rate): Applied to children's car seats, home energy, heating controls, and some renovation work
• 0% (Zero Rate): Applied to most food items, children's clothes, books, newspapers, and prescription medicines

How to Add VAT:

To add VAT to a price, multiply the net amount by (1 + VAT rate as decimal). For 20% VAT: Net Price × 1.20 = Gross Price

Example: £100 × 1.20 = £120 (£100 net + £20 VAT)

How to Remove VAT:

To remove VAT from a gross price, divide by (1 + VAT rate as decimal). For 20% VAT: Gross Price ÷ 1.20 = Net Price

Example: £120 ÷ 1.20 = £100 (£20 is the VAT amount)

Percentage Change Calculator

The percentage change calculator helps you determine the percentage increase or decrease between two values. This is essential for tracking price changes, analyzing growth rates, and comparing values over time.

Percentage Change Formula:

((New Value - Old Value) / Old Value) × 100

Examples:

• Price increased from £80 to £100: ((100 - 80) / 80) × 100 = 25% increase
• Price decreased from £100 to £75: ((75 - 100) / 100) × 100 = -25% decrease

A positive result indicates an increase, while a negative result indicates a decrease. This calculator is perfect for analyzing sales data, stock prices, salary changes, and business metrics.

Percentage Increase Calculator

Use the percentage increase calculator when you need to add a percentage to a number. This is useful for calculating price increases, adding tips, determining salary raises, or applying markup.

Formula:

New Value = Original Value × (1 + Percentage / 100)

Common Uses:

• Restaurant Tips: Calculate a 15% tip on a £50 meal: £50 × 1.15 = £57.50
• Salary Raises: £30,000 salary + 5% raise: £30,000 × 1.05 = £31,500
• Price Increases: £100 product + 12% increase: £100 × 1.12 = £112
• Retail Markup: £50 cost + 40% markup: £50 × 1.40 = £70 selling price

Percentage Decrease Calculator

The percentage decrease calculator helps you subtract a percentage from a number. This is essential for calculating discounts, price reductions, depreciation, and sales.

Formula:

New Value = Original Value × (1 - Percentage / 100)

Practical Applications:

• Sale Discounts: £200 jacket with 30% off: £200 × 0.70 = £140
• Clearance Sales: £500 item with 60% discount: £500 × 0.40 = £200
• Student Discounts: £15 ticket with 20% student discount: £15 × 0.80 = £12
• Early Bird Pricing: £100 course with 25% early discount: £100 × 0.75 = £75

Percentage Calculator Tips and Tricks

Mental Math Shortcuts:

• 10%: Simply divide by 10 (move decimal point left)
• 5%: Calculate 10% and divide by 2
• 1%: Divide by 100 (move decimal point two places left)
• 15%: Calculate 10% + 5%
• 20%: Divide by 5 or calculate 10% × 2
• 25%: Divide by 4
• 50%: Divide by 2

Common Mistakes to Avoid:

• Don't confuse percentage points with percentages (50% to 60% is a 10 percentage point increase but a 20% relative increase)
• Remember that consecutive percentages don't add up (a 20% increase followed by 20% decrease doesn't return to original)
• Always use the correct base value when calculating percentage changes
• Be careful when removing VAT - don't just subtract the percentage, use the correct division formula
