The **POWER** function raises a number to a specified exponent in LibreOffice Calc. It is equivalent to using the `^` operator but is often preferred for clarity, readability, and compatibility. `POWER` is essential in financial modeling, scientific calculations, growth formulas, and any scenario involving exponents.

What the POWER Function Does

  • Raises a number to a specified exponent
  • Supports positive, negative, and fractional exponents
  • Works with integers, decimals, and expressions
  • Useful for growth models, compounding, geometry, and scientific math
  • Equivalent to the ^ operator

It is designed to be precise, flexible, and universally compatible.

Syntax

POWER(number; exponent)

Arguments

  • number:
    The base value.

  • exponent:
    The power to raise the base to.
    Examples:

    • 2 → square
    • 3 → cube
    • 0.5 → square root
    • -1 → reciprocal

Basic Examples

Square a number

=POWER(5; 2)

Returns 25.

Cube a number

=POWER(3; 3)

Returns 27.

Square root using POWER

=POWER(16; 0.5)

Returns 4.

Reciprocal using POWER

=POWER(10; -1)

Returns 0.1.

POWER with a cell reference

=POWER(A1; 2)

Squares the value in A1.

Advanced Examples

Exponential growth

=POWER(1 + A1; B1)

Useful for compound interest or growth factors.

POWER with negative bases

=POWER(-2; 3)

Returns -8.

Fractional exponents (roots)

=POWER(A1; 1/3)

Returns the cube root of A1.

POWER with formulas

=POWER(A1 - B1; 2)

Squares the difference between A1 and B1.

Equivalent using ^ operator

=A1 ^ 2

Same result as POWER(A1; 2).

POWER for geometry

=POWER(A1; 2) + POWER(B1; 2)

Useful for Pythagorean calculations.

Common Errors and Fixes

Err:502 — Invalid argument

Occurs when:

  • number is negative and exponent is fractional
  • exponent or number is non-numeric
  • the expression results in an undefined value

Fix:
Ensure the exponent is compatible with the base.

Err:503 — Numeric overflow

Occurs when:

  • The result is too large for Calc to represent
    Example: POWER(10; 400)

Fix:
Scale inputs or use logarithmic transformations.

POWER returns a complex number (not supported)

Cause:

  • Negative base with non-integer exponent
    Example: POWER(-4; 0.5)

Calc cannot compute imaginary results.

Best Practices

  • Use POWER for clarity when formulas become complex
  • Use the ^ operator for quick inline exponentiation
  • Avoid fractional exponents on negative bases
  • Use POWER for growth, compounding, and geometric formulas
  • Use SQRT for readability when exponent is 0.5
POWER is ideal for financial and scientific models where exponentiation must be explicit and readable.
  • Use SQRT for square roots
  • Use EXP for natural exponentiation
  • Use LN or LOG for logarithmic transformations
  • Use A1 ^ B1 as a shorthand for POWER(A1; B1)
  • Use PRODUCT for multiplication-based growth models

By mastering POWER and its combinations with other math functions, you can build precise, scalable numeric models in LibreOffice Calc that handle exponentiation cleanly and consistently.

Reproducible example (tested in LibreOffice Calc)

This standalone example was calculated in LibreOffice Calc 25.2.3.2 and matched the expected value. It is a practical cross-check of one usage, not proof that every example elsewhere on this page is correct.

=POWER(2;3)

Expected result: 8.

Raise a base to a whole-number exponent.

If the result differs, check the referenced cells, argument separators and number formatting. For more information, consult the LibreOffice Calc official help.
