This calculator runs locally in your browser and does not send expressions to a server. It is designed for fast everyday math, keyboard input and privacy-friendly use when you are already working inside MyIPScan tools.
Use it for quick percentages, powers, grouped expressions and simple checks while troubleshooting IP, DNS or network settings. For financial, legal or engineering-critical calculations, verify important results with a second trusted tool.
Runs simple calculations locally in the browser.
The expression is evaluated in the browser and shown next to the expression that produced it, so a surprising answer can be traced back to what was actually typed.
No. All calculations run entirely in your browser using JavaScript. Nothing you type is sent to any server. You can use it offline after the page loads, and no calculation history is stored anywhere.
Standard arithmetic: addition, subtraction, multiplication, division, percentages, and brackets for order of operations. For network-specific calculations like subnet masks and CIDR ranges, use the dedicated Subnet Calculator.
A browser calculator is always available regardless of your device, works the same on mobile and desktop, and can be linked to or bookmarked. It is also useful when working in a browser tab and you need a quick calculation without switching applications.
