When To Retire and Replace Fleet Vehicles: A Strategic Guide for Optimal Efficiency

Ageing fleet vehicles are a drain on your business. They cause unexpected downtime, add to your fleet maintenance and fuel costs, and can even pose a threat to driver safety. According to one estimate, ageing fleets cost UK businesses an extra £2.4bn per year.

Therefore, knowing when to retire and replace fleet vehicles is critical. In this guide, we’ll cover key indicators that tell you when it’s time to replace a vehicle, plus help you develop a strategic vehicle replacement plan so you can keep your fleet operating at full capacity.

Key Takeaways

• Holding onto ageing fleet vehicles can cost your business money. Creating a plan for when to retire and replace fleet vehicles is an important part of vehicle lifecycle analysis.
• Key metrics to consider when deciding whether to retire a vehicle include total cost of ownership, cost per mile, age, mileage, maintenance costs, and downtime frequency.
• Technology like telematics and fleet management software can help you track vehicle performance and decide when to retire a vehicle.
• Be strategic about retiring and replacing vehicles. Have policies in place to govern vehicle retirement, consistently set aside money to pay for new vehicles, and adopt a phased replacement approach to spread capital expenditures over time.

Understanding Vehicle Lifecycle and Total Cost of Ownership

Thinking about retiring and replacing vehicles is a key part of a broader approach to fleet management, known as vehicle lifecycle analysis. This analysis looks holistically at a vehicle’s total lifespan, from acquisition to disposal, and attempts to maximise the value the vehicle brings to your business.

Retirement is important because fleet vehicles age. After a certain number of years or miles, wear and tear add up, and vehicles are more likely to break down or need expensive maintenance. Older vehicles also tend to have higher carbon footprints. At some point, the extra costs of continuing to own a vehicle can exceed the value that vehicle brings to your fleet.

The challenge for fleet managers is figuring out when that threshold is going to be crossed – and working proactively to retire and replace a vehicle before it starts costing your business money.

Total cost of ownership

One of the best ways to measure when a vehicle’s value starts declining is to track its total cost of ownership (TCO). This is a metric that aims to capture the full cost of owning a fleet vehicle, from when your business purchases it to when you retire it.

Total cost of ownership can be calculated as:

(Vehicle Acquisition Cost + Fixed Costs + Variable Costs + Operating Costs) – Vehicle Resale Value

• Acquisition cost: The total cost to purchase a vehicle, including any deposit and financing fees.
• Fixed costs: Costs you must pay monthly or annually, such as lease or loan payments, insurance premiums, and vehicle registration fees.
• Variable costs: Costs that vary over time as you operate a vehicle, such as costs for fuel, regular fleet maintenance, unexpected repairs, tolls, and driver wages.
• Operating costs: Costs related to fleet support infrastructure, such as fleet administrator salaries and fleet management software costs.
• Vehicle resale value: The amount of money you could get by selling or trading in your vehicle.

You can calculate a vehicle’s TCO by estimating the lifespan of the vehicle and using historical data about its performance to predict future costs. As you recalculate TCO annually or semi-annually, it should stay nearly constant for a well-functioning, young vehicle. If a vehicle’s TCO increases, it indicates that it’s becoming more of a financial drag on your business and should be considered for retirement.

Cost per mile

Another important metric to consider when evaluating whether to retire and replace vehicles is cost per mile (CPM). This metric accounts for the total cost to operate a vehicle over a given period, divided by the mileage the vehicle is driven during that same period. Costs should include all fixed, variable, and operational costs paid during the selected timeframe.

CPM should be consistent over time for a healthy vehicle. A climbing CPM often indicates potential maintenance issues or declining performance, which signals that replacement may be necessary. Just keep in mind that CPM can also increase due to rising fuel prices or driver wages, so it’s important to pay attention to changes in these variable costs when conducting a CPM analysis.

Key Indicators for Vehicle Replacement

In addition to TCO and CPM, there are several other indicators to monitor that can signal it’s time to replace a fleet vehicle.

• Age and mileage: Age and mileage can be used as general indicators of how much wear and tear a vehicle has experienced. On average, light-duty vehicles should be considered for replacement after four years or 100,000 miles. Heavy-duty lorries should be considered for replacement after 10 years or 250,000 miles.
• Maintenance and repair costs: Escalating maintenance costs are a sign that a vehicle is ageing and could need even more expensive fixes in the future. It’s typically more cost-efficient to replace a vehicle than pay for repeated high-cost repairs.
• Downtime frequency: Breakdowns and downtime for repairs can hamper your business’s productivity and increase your fleet costs. If a vehicle is frequently unable to be used, it’s time to consider replacing it.
• Safety and compliance issues: Ageing vehicles with repairs that have been put off can present safety issues or even leave your business at risk of non-compliance with fleet regulations. Older vehicles may also lack modern safety features. Accidents can be extremely costly, so safety concerns may necessitate replacing a vehicle sooner rather than later.

Utilising Data and Technology in Replacement Decisions

Technology can play an important role in helping you make informed decisions about when to replace fleet vehicles. For example, onboard telematics devices track metrics like engine performance, miles driven, and fuel consumption, enabling you to monitor changes in efficiency over time.

Fleet management software goes even further, incorporating data about a vehicle’s maintenance history and downtime. It can even update a vehicle’s TCO in real time and alert you if a vehicle is becoming more expensive to keep.

Another benefit of fleet management systems is that they offer predictive analytics features. They can use data about a vehicle’s performance and maintenance history to forecast when major repairs will be needed, enabling you to act before a breakdown happens.

In addition, they can predict when fleet vehicles should be replaced and help you build a schedule for retiring vehicles. This is important for giving you the flexibility to service or replace a vehicle when it has the least impact on your business operations, instead of whenever an emergency arises.

Developing a Strategic Replacement Plan

In addition to monitoring replacement indicators, it’s important to have a strategic plan and schedule for replacing vehicles. This takes some of the uncertainty out of when to retire a vehicle and can help your business manage the capital expenses associated with purchasing new fleet vehicles.

Establish replacement policies

First, fleet managers should establish policies or replacement standards for when vehicles are eligible for retirement. They can focus on a vehicle’s age or mileage, performance metrics like TCO or CPM, or downtime over a preset timeframe. Policies can also vary by vehicle type or use.

Importantly, these policies can clarify which vehicles should be considered for retirement, not necessarily specify when vehicles must be retired. This approach can help fleet managers focus resources while still leaving flexibility to replace vehicles at the perfect time.

Budget for replacement vehicles

Most of the time, when your business retires a fleet vehicle, you’ll need to replace it. That means you must be prepared to make a large capital expenditure at the time you retire a vehicle.

A good way to do this is to start setting aside money for a replacement as soon as you purchase a vehicle. Each month, contribute a fixed amount to a new vehicle fund and don’t use this money for other expenses, like regular maintenance costs. When it’s time to replace a vehicle, you’ll have at least a significant portion of the cost already budgeted for.

Adopt a phased replacement approach

Replacing all of your fleet vehicles at the same time can be extremely disruptive to your business, not to mention costly. For most businesses, adopting phased replacement, in which you stagger vehicle replacements over time, is more effective.

Use historical data to predict when each vehicle in your fleet will approach retirement. You can then push some retirement dates back and pull some forward to spread them out over time. Fleet management software can be very helpful here, since it can automatically predict replacement cycles for each vehicle and update your schedule as the condition of vehicles changes.

Disposal and Resale Considerations

When it comes time to retire a vehicle, there are a few important things to keep in mind.

Resale value

A vehicle’s resale value is an important part of its TCO, and maximising resale value can help you get more out of your fleet. You can use sites like Parkers and Autotrader to estimate the value of a vehicle you’re getting ready to sell.

Importantly, market conditions can have a big impact on the resale value of a vehicle. So, it’s worth monitoring used car prices and potentially retiring a fleet vehicle earlier if it will fetch a higher price.

Disposal methods

There are many options for selling a fleet vehicle. Some of the most popular include:

• Private sale
• Auctions
• Trade-in
• Donation
• Recycling

Each of these methods has benefits and drawbacks. For example, you might get the most money for your vehicle in a private sale, but finding a buyer can be a lot of work and may take a long time to sell.

Trade-ins are convenient, especially if your fleet procurement strategy involves buying a new fleet vehicle from a dealer. However, you’re unlikely to get the maximum resale value for your vehicle.

Recycling should only be considered for vehicles with no resale value since you’ll receive little or no money in return.

Environmental and regulatory compliance

It’s also important to be aware of any rules surrounding vehicle sales. For example, there are environmental regulations that govern how vehicles at the end of their lives can be disposed of.

No matter what method you choose to dispose of a vehicle, make sure the title and registration are transferred to the new owner. This ensures your business is no longer legally responsible for it.
