Average Calculator: Find the Mean Instantly

Ever needed to quickly calculate an average but found yourself adding up numbers and dividing manually? Whether you’re tracking business performance, calculating exam scores, or analysing investment returns, our Average Calculator does the work for you—instantly and accurately.

How It Works:

Percentage Calculator: Quickly Calculate Increases, Decreases & More

Percentages play a huge role in everyday life—from sale discounts to tax calculations, investment returns, and loan interest rates. Our Percentage Calculator helps you accurately determine percentage changes, increases, decreases, and differences—saving you time and effort.

How It Works:

Simply input the values you want to calculate, and our tool will generate the percentage result instantly. This is especially useful for:

• Shoppers calculating discounts and final sale prices
• Homeowners estimating mortgage interest rate changes
• Business owners measuring profit margins and revenue growth
• Taxpayers calculating VAT (Value Added Tax) or PAYE tax contributions
• Investors tracking percentage gains or losses in stock market investments

Finding a Discounted Price

You’re shopping online, and a store is offering 25% off a jacket that costs €80. Instead of manually calculating, just enter the original price (€80) and the discount percentage (25%) into our Percentage Calculator. You’ll instantly see that the discount is €20, making the final price €60.

For example, if you want to calculate investment growth:

You invested €5,000, and over time, your investment increased by 12%. Instead of manually multiplying, just enter your initial investment (€5,000) and the percentage growth (12%) into our calculator. You’ll instantly see that your investment has grown by €600, making it €5,600 in total.
