Overview

The Depreciation Calculator allows you to compare four major depreciation methods side by side: straight-line, declining balance, sum-of-the-years'-digits (SYD), and units of production. By entering your asset's cost, salvage value, and useful life, you can instantly generate a year-by-year depreciation table and book-value curves to determine the most tax-efficient or accurate accounting method for your business assets.

When to use

When comparing different accounting methods to optimize tax planning for new capital assets.
When calculating the annual depreciation expense and remaining book value of machinery, vehicles, or equipment over their useful life.
When evaluating asset depreciation based on actual usage or production output rather than just elapsed time.

How it works

1Enter the initial asset cost, estimated salvage value at the end of its life, and the useful life in years.
2Optionally adjust the declining balance multiplier or input comma-separated annual usage values for the units of production method.
3The calculator computes the annual depreciation expense, accumulated depreciation, and ending book value for each year across all selected methods.
4Review the generated comparative table and book-value curves to analyze how each method impacts your asset's value over time.

Use cases

Financial planning to choose between straight-line and accelerated depreciation for corporate tax reporting.
Equipment management to track the book value of company vehicles based on annual mileage or usage.
Academic or professional accounting training to visualize how different depreciation formulas affect asset valuation over time.

Examples

1. Standard Corporate Asset Depreciation

Corporate Accountant

Background

An accountant needs to determine the depreciation schedule for a new server stack purchased for $50,000, with an expected salvage value of $5,000 after 5 years.

Problem

The accountant needs to compare straight-line, double-declining balance, and sum-of-the-years'-digits methods to decide which fits the company's financial strategy.

How to use

Enter 50000 as the Asset Cost, 5000 as the Salvage Value, 5 as the Useful Life, and set the Declining Balance Multiplier to 2.

Asset Cost: 50000, Salvage Value: 5000, Useful Life: 5, Declining Balance Multiplier: 2

Outcome

The tool generates a comparative table showing a steady $9,000 annual depreciation for straight-line, while double-declining balance front-loads the depreciation with $20,000 in the first year.

2. Manufacturing Machinery Usage Depreciation

Operations Manager

Background

A factory manager wants to track the depreciation of a CNC machine costing $120,000, with a salvage value of $20,000, based on actual production hours over 5 years.

Problem

The manager needs to calculate depreciation using the units of production method alongside standard time-based methods.

FAQ

What depreciation methods can I compare?

You can compare straight-line, declining balance (including double-declining), sum-of-the-years'-digits (SYD), and units of production methods.

How do I calculate units of production depreciation?

Enter the comma-separated usage values per year in the units of production input field to calculate depreciation based on actual asset wear.

What is the declining balance multiplier?

It is the factor applied to the straight-line rate. For example, a multiplier of 2 calculates double-declining balance (DDB) depreciation.

Can I customize the decimal precision of the calculations?

Yes, you can specify the number of decimal places from 0 to 6 for the calculated depreciation values.

What is salvage value?

Salvage value is the estimated book value of an asset after its useful life has ended, representing what it can be sold for.

Asset Cost: 120000, Salvage Value: 20000, Useful Life: 5, Units of Production: 4000, 3500, 3000, 2500, 2000
