Everyday percentage calculations made simple
Percentages appear everywhere in daily life, from store discounts and restaurant tips to sales tax, interest rates, test scores and statistics. This all-in-one percentage calculator handles the three most common needs. Use the first mode to find a percentage of a number, such as 15 percent of a 60 dollar bill for a tip. Use the second mode to see what percentage one value is of another, like a score out of a total. Use the third mode to add or subtract a percentage, ideal for applying a discount or adding tax to a price. Each calculation runs instantly as you type, with no complicated formulas to remember. Everything is computed locally in your browser, so your numbers stay private and results appear without any waiting.
Frequently Asked Questions
How do I calculate a discount price?
Use the add or subtract mode. Enter the original price and the discount percentage, then subtract to see the final price. For example, subtracting 20 percent from 50 gives a sale price of 40.
Are my calculations kept private?
Yes. Every calculation runs entirely in your browser and nothing you type is uploaded or stored. Your figures, whether budgets, salaries or invoices, remain completely private on your own device.
How do I work out what percentage one number is of another?
Use the second mode and enter both numbers. The tool divides the first by the second and multiplies by 100. For instance, 30 out of 120 is calculated as 25 percent instantly.
