Calculator — Common Questions
Does this calculator send my input to a server?
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.
What operations does this calculator support?
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.
Why use a browser calculator instead of the OS 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.
