What Calculate Declining Balance Depreciation can do:

The Calculate Declining Balance Depreciation tool uses a percentage rate you choose, making it flexible for scenarios like custom tax depreciation schedules or estimating real-world asset decline. It’s a generalization of the double-declining method but with any rate 20%, 40%, even 60% if needed.

You’ll get an annual breakdown (if toggled), a final book value, and total depreciation calculated precisely. Rounding is optional. Everything updates instantly.

Example:

Settings: Asset Cost: 10000, Salvage Value: 1000, Useful Life: 5, Decline Rate: 40 Show Breakdown: ON, Round Values: OFF

Output:

Year 1: 4000.00
Year 2: 2400.00
Year 3: 1440.00
Year 4: 864.00
Year 5: 296.00
Ending Book Value: 1000.00
Total Depreciation: 9000.00

Common Use Cases:

This tool is great for accountants, analysts, or business owners who need more flexibility than DDB allows. It’s also useful for students studying depreciation methods or for custom forecasting tools where decline isn’t uniform.

Useful Tools & Suggestions:

To explore different ways declining balance works, the Fixed Rate Declining Balance Calculator gives you a straightforward view using a constant rate perfect if you want predictable depreciation each year. And the Variable Declining Balance Depreciation Tool lets you adjust the rate as needed, which helps if asset usage or value loss changes over time.
