Universal calculator

Type an expression in one line. Results update as you type; save lines to history (Advanced) or copy the result.

What it does

The universal calculator uses a safe math parser (not raw JavaScript). It supports addition, subtraction, multiplication, division, exponentiation with ^, percent notation, and nested parentheses. Commas and periods work as decimal separators.

How to use

  1. Type a formula in the expression field.
  2. Watch the result update live (short debounce for performance).
  3. Press Enter or Save to history to append a line (Advanced shows the list).
  4. Use Copy result to paste the value elsewhere.
  5. Share a preset via URL: add ?q=1%2B1 (URL-encoded expression).

FAQ

  • Is this different from a regular calculator?

    Yes. You type expressions like in a spreadsheet or search bar: parentheses, exponents, percents. It is optimized for quick formulas, not a button grid.

  • Is my history stored on your servers?

    No. History is saved only in your browser (localStorage) on this device unless you clear it.

  • Does it replace your specialized calculators?

    No. It is a fast scratchpad for expressions. For mortgages, loans, taxes, or conversions, use the dedicated calculators for structured inputs and guidance.
