Percentage Calculator
Percentage Calculator online.
An Online Percentage Calculator is a simple and free tool that helps you quickly calculate percentages for any purpose — whether you’re managing finances, solving math problems, tracking discounts, or analyzing data. It lets you find percentage values, percentage increases or decreases, and convert fractions or ratios into percentages instantly. You can use it for business, education, shopping, or daily life tasks without needing to remember complicated formulas.
The Percentage Calculator works in three main ways. First, you can find a percentage of a number — for example, what is 20% of 500? Enter 20 and 500, and the calculator instantly gives 100. Second, you can find what percent one number is of another — for example, 50 is what percent of 200? The answer is 25%. Third, you can calculate increase or decrease percentages, like if your salary went from ₹25,000 to ₹30,000, the calculator shows a 20% increase. These are the most common real-world percentage calculations people need every day.
This online calculator eliminates the need for manual math or complex formulas. Normally, to calculate percentages, you’d use formulas such as:
(Value × Percentage) ÷ 100 for finding part of a number.
(Part ÷ Total) × 100 for finding percentage share.
[(New Value − Old Value) ÷ Old Value] × 100 for percentage change.
The tool performs these instantly and accurately, allowing you to focus on understanding results rather than doing arithmetic.
The Online Percentage Calculator supports all major currencies, numbers, and decimal formats. You can use it for school exams, business analysis, or personal budgeting. For example, students use it to find exam scores and grade percentages, while business owners use it for profit margins, tax rates, or price markups. Shoppers use it to quickly calculate discounts — if an item worth ₹2,000 has a 30% discount, the tool instantly shows that you’ll pay ₹1,400. Similarly, investors use it to check percentage returns on stocks or mutual funds.
It’s also useful for professionals in finance, accounting, and marketing who frequently need to calculate GST, interest rates, commissions, profit percentages, or data growth. With the Percentage Calculator, you avoid errors that come from manual rounding or misplaced decimals. It provides real-time results and can handle both small and large numbers easily.
On Narbariya.com, the Percentage Calculator is fast, accurate, and mobile-friendly. It allows you to perform all common percentage operations in one place:
Find percentage of a number
Find what percent one number is of another
Find percentage increase or decrease
Reverse percentage (find original value before discount or increase)
You can switch between these modes easily and get instant results. For example, if you know the final price after discount and the percentage of discount, the calculator can also find the original price. This makes it a complete all-in-one percentage tool for any kind of calculation.
