Are You "Car Poor"? Why Overspending on Car Finance Can Cost You Thousands

Updated August 2025

In the UK, owning a car has long been a symbol of freedom and convenience. But in recent years, the rise of Personal Contract Purchase (PCP) finance, higher insurance premiums, and record-high fuel prices have left many drivers in a financial trap: being “car poor”.

Being car poor means a significant chunk of your income, sometimes 25% or more, goes towards car-related costs, leaving little room for saving, investing, or other priorities. The result is a depreciating asset that eats away at your long-term financial security.

Quick rule of thumb: Aim to keep total car costs under 10% to 15% of your take-home pay. If you are consistently above 20%, review and reduce.

What Does “Car Poor” Look Like?

It is not just about having a luxury car on finance. It is about your car expenses taking up a disproportionate share of your monthly income. This can include:

For example, someone earning £2,500 after tax might spend:

Monthly item Amount
Finance payment £400
Insurance £100
Fuel £200
Servicing and tax (averaged) £50
Total £750
Share of £2,500 take-home 30%

The Real Cost of Depreciation

Unlike a house, which can increase in value over time, a car is almost always a depreciating asset. That brand new £25,000 car might be worth only £15,000 after three years, and you are paying interest on top of that loss.

When you combine depreciation with finance charges, you can end up spending thousands of pounds for the privilege of driving a car that is losing value every single day.

PCP Pitfalls To Watch

What If You Invested That Money Instead?

Here is where the opportunity cost becomes clear. Imagine that instead of spending £750 per month on car expenses, you drove a cheaper, reliable used car costing half as much to run, freeing up £375 per month.

If you invested that £375 every month into a Stocks & Shares ISA with an average annual return of 6%, here is what you could have after different time periods:

Time period Total invested Estimated value (6% return)
5 years £22,500 ~£26,000
10 years £45,000 ~£61,500
20 years £90,000 ~£173,000

That is the power of redirecting money from a depreciating asset to an appreciating one.

Signs You Might Be Car Poor

How To Escape the Car Poor Trap

If you realise you are spending too much on your car, use these steps:

Audit Your Car Costs In 10 Minutes

  1. List every monthly cost: finance, insurance, fuel, parking, tax, servicing, breakdown.
  2. Add one-twelfth of yearly items like MOT and tyres.
  3. Divide the total by take-home pay to get your percentage.
  4. If above 15%, pick at least two actions from the list above to bring it down.

Mindset Shift: From Status To Stability

Many people buy cars that reflect their desired image rather than their financial reality. Social pressure and advertising fuel the idea that a shiny new car equals success, but it can mean years of delayed financial progress.

By shifting your mindset from “What will people think?” to “How will this help my future?”, you can make car choices that support your long-term goals.

FAQs

Is leasing cheaper than PCP?

Leasing can have lower monthly payments, but you never own the car and there can be mileage and damage charges. Compare the total cost over the whole term, not just the monthly figure.

Should I buy new or nearly-new?

Nearly-new cars often avoid the steepest early depreciation while still giving you a modern, reliable vehicle with warranty cover.

What is negative equity?

Negative equity is when the car is worth less than the remaining finance. Rolling it into a new agreement increases your debt and monthly costs.

Final Thoughts

Being car poor is one of the most common and avoidable money traps in the UK. By reducing your car expenses and redirecting the savings into investments, you are not just cutting costs, you are building wealth.

The next time you are tempted by a new car on finance, run the numbers. Ask yourself: “Would I rather impress people for a few years, or secure my financial freedom for decades?”
