# Depreciation Calculator

Calculate the depreciation of an asset using the straight line, declining balance, double declining balance, or sum-of-the-years’ digits method.

## Depreciation Schedule:

2022 | $19,000 |

2023 | $19,000 |

2024 | $19,000 |

2025 | $19,000 |

2026 | $19,000 |

## Straight Line Depreciation Formula

depreciation = asset cost – salvage value / service life

## Declining Balance Depreciation Formula

depreciation = value × factor × 1 / service life

**Where:**

value = depreciable value at the beginning of the year

service life = years of useful life

factor = depreciation factor

## Double Declining Balance Depreciation Formula

depreciation = value × 2 × 1 / service life

**Where:**

value = depreciable value at the beginning of the year

service life = years of useful life

## Sum-of-the-Years’ Digits Depreciation Formula

depreciation = (asset cost – salvage value) × factor

**Where:**

n = service life in years

factor = years of service life remaining divided by the sum of each year’s digits (see example below)

year 1 factor = n / 1 + 2 + … + n

year 2 factor = n – 1 / 1 + 2 + … + n

final year factor = 1 / 1 + 2 + … + n
