Real-World Examples

Wondering when you might actually need to pull this tool up? Here are a couple of incredibly common everyday scenarios:

Scenario 1: Splitting the Dinner Bill You are out to dinner with three of your friends. The total bill, including tax and tip, comes out to $145.60. Nobody wants to do the mental gymnastics to figure out exactly what they owe. You pull up this calculator, type in 145.60, hit the ÷ button, type 4, and hit =. Instantly, you see that everyone owes exactly $36.40. Problem solved in five seconds!

Scenario 2: Calculating a Discount You’re shopping online and find a jacket you really want. It costs $85, but you have a coupon code for 20% off. You need to figure out how much you are actually going to save. You open the calculator, type 85, hit ×, type 0.20 (which is 20% as a decimal), and hit =. The calculator shows $17. You now know you’ll save $17, bringing the final price down to $68.


Why Keep Things Simple?

In a world where technology is constantly getting more complicated, there is something incredibly refreshing about a tool that just does exactly what it’s supposed to do, and nothing more. You don’t need a massive scientific calculator with trigonometric functions just to balance your budget.

Our standard calculator is built on the philosophy of frictionless utility. It loads instantly, it doesn’t bog your browser down, and it gives you accurate results without making you think too hard.

Our standard calculator evaluates expressions linearly as you type, so keep that in mind for complex equations!
