An illustrated guide on calculating and managing asset depreciation with the right rental management software.

What is Depreciation?

Common Depreciation Methods

There are several ways to calculate depreciation, and the choice of method depends on the nature of the asset and business requirements. Below are the most commonly used approaches:

1. Straight-Line Depreciation

This method evenly distributes the depreciation amount over the asset’s useful life. It is the simplest and most widely used depreciation technique.

Annual Depreciation = Cost of Asset - Salvage Value Useful Life (in years)

Example:

If a forklift is purchased for $50,000, expected to last 10 years, with a salvage value of $5,000:

Annual Depreciation = 50,000 - 5,000 10 = 4,500

This means $4,500 is recorded as depreciation each year.

2. Declining Balance Depreciation

This accelerated method applies a higher depreciation expense in the earlier years of an asset’s life. It is beneficial for businesses dealing with assets that lose value more rapidly, such as technology-intensive machinery.

  • Double-Declining Balance: Depreciates at twice the straight-line rate, allowing businesses to write off a larger portion of the asset’s cost early on.

3. Units of Production Depreciation

Unlike the previous methods, this approach bases depreciation on actual usage rather than time. This is ideal for assets that have variable usage rates.

Depreciation per Unit = Cost of Asset - Salvage Value Total Expected Units of Usage

Multiply this rate by the actual number of units produced or hours used in each period.

How to Calculate Depreciation: A Practical Example

Let’s consider an example to illustrate the depreciation process.

A backhoe loader is purchased for $75,000, expected to last 10 years, with an estimated salvage value of $10,000. Using the straight-line method, the calculations would be:

Depreciable Base = 75,000 - 10,000 = 65,000
Annual Depreciation = 65,000 10 = 6,500

Thus, $6,500 is recorded annually as depreciation.

Why Should You Track Asset Depreciation for Your Rental Business

Depreciation has a significant financial impact on rental businesses. For example, Hertz Global Holdings recorded a $1 billion asset impairment charge and an 89% increase in depreciation expenses, underscoring its effect on profitability.

Proper depreciation tracking helps rental businesses in key areas:

  • Optimizing Rental Pricing – Factoring in depreciation ensures rental rates cover asset devaluation and operational costs, maintaining profitability while staying competitive.
  • Strategic Asset Planning – Depreciation data helps rental businesses forecast asset replacement cycles, avoiding unexpected downtime and costly repairs.
  • Maximizing ROI – If rental revenue doesn’t offset depreciation and maintenance costs, businesses must adjust pricing, utilization, or asset investments for long-term profitability.

The Role of a Rental Management Software in Asset Depreciation Tracking

Managing asset depreciation effectively is crucial for rental businesses to set competitive pricing, optimize asset utilization, and enhance financial planning. Rental management software simplifies this process by automating depreciation tracking, reducing manual errors, and providing real-time financial insights.

Here is how it transforms the way you manage depreciation:

  • Automated and Accurate Depreciation Tracking
  • Real-Time Asset Valuation & Pricing Insights
  • Optimized Asset Lifecycle Planning
  • Tax & ROI Optimization

Depreciation is not just an accounting necessity—it’s a strategic financial tool that enables rental businesses to maintain profitability, extend asset lifespans, and drive informed decision-making.

By adopting a robust management system, businesses can gain automated, data-driven insights that improve pricing strategies, asset management, and this ensures sustainable growth and maximum profitability.
