1. Percentage Calculator Online
The Percentage Calculator Online is the most used tab on this page. Almost everyone needs to calculate percentages at some point — whether it is for exam marks, shopping discounts, salary hikes, business growth, or comparing two numbers.
Our percentage calculator online supports three types of calculations. You can find what percentage one number is of another. You can also find the percentage of any number. And you can calculate the percentage change between two values, which is very useful for tracking growth or decline over time.
For example, if your monthly sales went from Rs. 80,000 to Rs. 1,00,000, this percentage calculator online will instantly tell you that your growth is 25 percent. No manual formula needed.
Students use this calculator for marks and grades. Business owners use it for profit tracking. Professionals use it for data reporting and analysis.
2. Discount Calculator
Shopping during a sale season? Our Discount Calculator helps you instantly find out how much you are saving and what the final price will be after the discount.
Just enter the original price and the discount percentage. The tool will show you the exact amount you save and the final price you pay. It also shows a simple chart so you can visually see the split between what you pay and what you save.
This discount calculator supports both INR and USD currency formatting, making it useful for both Indian and international users. It is perfect for online shoppers, retail store owners, and anyone who deals with pricing on a daily basis.
3. Margin and Markup Calculator
Many business owners confuse profit margin with markup. They are different, and both matter when you are pricing your products.
Our Margin and Markup Calculator calculates both at the same time. Profit Margin is calculated as a percentage of the selling price. Markup is calculated as a percentage of the cost price.
For example, if you buy a product for Rs. 600 and sell it for Rs. 900, this calculator will instantly show you that your Profit Margin is 33.3 percent and your Markup is 50 percent. This helps you price your products correctly and ensure your business stays profitable.
This tool is very useful for retail shop owners, e-commerce sellers, wholesalers, and manufacturers.
4. ROI Calculator – Return on Investment
Before putting money into any business, project, or investment, you need to know if it is worth it. That is exactly what our ROI Calculator helps you find out.
ROI stands for Return on Investment. It tells you how much profit or loss you made compared to what you invested. Our ROI calculator shows three results the total gain or loss, the ROI percentage, and the Annualized ROI which is also known as CAGR.
For example, if you invested Rs. 50,000 in a business and got back Rs. 65,000 after one year, your ROI is 30 percent. If the same return happened over two years, your Annualized ROI would be around 14 percent.
This calculator is used by investors, startup founders, marketing teams, and anyone who wants to evaluate whether their money is working hard enough.
5. Break-even Calculator
Every business needs to know how much it needs to sell before it starts making a profit. This is called the break-even point, and our Break-even Calculator finds it instantly.
You just need to enter three numbers — your fixed costs, your selling price per unit, and your variable cost per unit. The calculator will tell you exactly how many units you need to sell to cover all your costs and reach the break-even point.
For example, if your monthly fixed costs are Rs. 30,000, you sell each item for Rs. 400, and your variable cost per item is Rs. 250, you need to sell 200 units per month to break even. Anything above 200 units is pure profit.
This is a must-use tool for anyone starting a new business, launching a new product, or planning their monthly budget.
