SYD Function (LibreOffice Calc)

Financial Intermediate LibreOffice Calc

Learn the SYD function in LibreOffice Calc: Calculates the arithmetically declining value of an asset (depreciation) for a specified period.

The SYD function in LibreOffice Calc is used for this task: Calculates the arithmetically declining value of an asset (depreciation) for a specified period. Calculate sum-of-years-digits depreciation for the first year.

This guide explains how to read the formula, reproduce a concrete example, interpret its result and recognize common input mistakes.

Syntax and arguments

SYD(cost; salvage; life; period)
Argument Required? Meaning
Cost Yes Acquisition costs. The initial cost of the asset.
Salvage Yes Salvage: The remaining value of the asset at the end of its life.
Life Yes Useful life. The number of periods in the useful life of the asset.
Period Yes Period. The depreciation period which must have the same time unit as average useful life.

Calc formulas normally use semicolons (;) between arguments in common configurations; the displayed separator may depend on settings or locale.

Worked example

=SYD(1000;100;3;1)

Expected result: 450.

Why it works: Calculate sum-of-years-digits depreciation for the first year.

How to use it in your own spreadsheet

  1. Identify the cells or inputs that correspond to the sample values above.
  2. Enter the formula in an empty cell, changing the references or literal values to match your sheet.
  3. Compare the output with a manual check on a small known example.
  4. Extend the formula to a larger dataset only after you understand the result.

Common problems and practical checks

  • Confirm that the data represents the intended sample, population, rate or cash-flow timing.
  • Keep units and percentage conventions consistent; a mathematically valid result can still answer the wrong question.
  • A pasted formula may produce an error when it uses the other program’s argument separator or unsupported options.
