Unlock the Surprising Secret: How Ditching Your Car Could Fast-Track You to Homeownership!

Ever wondered if your car is secretly the sneakiest expense draining your wallet? I mean, we all love the convenience of hopping into our trusty metal chariots—but what if that very habit has quietly cost you a fortune over the decades? Recently, Monevator threw down the gauntlet with an eye-opening piece that made me pause my usual pedal-to-the-metal lifestyle and ask: what if I’d parked the car keys for good and invested that cash instead? The Investor swears by a staggering £300,000 to £450,000 payoff after 30 years of plowing those car savings into global equities. Sounds like a get-rich-slow scheme wrapped in a driving ban, right? But before you trade your ignition for a ticket on the bus, let’s dive deep into real-world numbers—raw, unvarnished, and stripped of fluff—exploring whether cutting out car ownership might actually pave the road to your financial independence… or just have you stuck waiting at the bus stop wondering what could’ve been.

LEARN MORE

I‘ve read many personal finance articles that claim you can save big by ditching your car and jet-packing, hover-boarding, or *shudder* walking everywhere instead.

Monevator published a good one recently, which prompted car-swerving frugalista The Investor to claim he could have spun his savings into £300,000 to £450,000, just by ploughing them into a global equities tracker these past 30 years.

If that’s right, then hopefully he’s gonna cut us in because The Accumulators regularly ferried TI and his glow-sticks around sundry West Country amenities during the 1990s. If you’re thinking bear-baiting and badger hassling, well, I can neither confirm nor deny.

So how big a payout did I forgo by keeping my pedal to the metal instead? Can you really rake in nearly half a mil in exchange for 30 years of hanging about for buses?

Put another way: can you buy yourself a nice house by investing your car money instead?

Real numbers

Let’s do the sums. Except this time, let’s use some proper hardcore FIRE numbers. We’ll skip the silly money that most finance bloggers claim Joe Average throws at their transport problems.

Monty Mercedes or whoever does not read FIRE blogs. Only aspiring money mavens are into FIRE, and they’re unlikely to be subsidising the car industry in the first place.

Instead, those pursuing financial independence on wheels will do savvier stuff:

Buy used motors with a reputation for reliability and a global surfeit of spare parts.
Avoid dick extensions that command a premium just for the badge.
Drive ‘boring’ cars if needs-be. We’re on a mission here!
Profit from other people’s depreciation.
Drive the thing for as long as possible so you don’t keep resetting the depreciation curve (but getting rid once bits start falling off.)
Don’t buy more car than they need. No armoured vehicles, no automated parking, no lane assist, no heated seat subscriptions. Just own a car you can actually drive, and stay on the right side of tax and insurance costs.
Reduce their car habit by turning to alternative remedies like walking, cycling, and catching the bus, where possible.

All of which keeps costs down to a degree that can surprise hand-waving automobile avoidants.

So with the stage set, what can you really save if you don’t own a car when two budget ninjas enter the ring?

In the red corner

Introducing the West Country Wonga Worrier: The Accumulator-tor-tor!

…Weighing in with annual car costs of 3,312 pounds.

Vital statistics:

Mileage: 6,000 p.a.
Next car cost: £1,000 p.a.
Taxes, fines, breakdown cover: on request

In the blue corner

It’s the lift-cadging, thrift-meister himself: The Invest-oooooor!

…Weighing in at 1000 to 1500 pounds per annum.

Vital statistics:

London Transport: A mystery
National Rail: A mystery
Global city home ownership premium: Let’s not worry about that
Shoe leather: Sunk costs!

Judge’s ruling

The Accumulator’s annual poundage is a fully itemised, all-in figure. It’s the average of the last three years of car-related expenses, rebased to 2026 prices.

The Investor’s costs, meanwhile, are as impenetrable as the mask he wears.

A fully-qualified member of the finger-in-the-air school of expenses-tracking, we’ll just have to rely on TI‘s best recollections. He assures me he has an excellent memory.

Sounds reasonable. Ahem.

What I’ll do then is calculate the match-up as a range of outcomes and leave it to the reader to decide which is closest to the truth.

Fight!

Round One

TI’s car-free costs are deducted from TA’s motoring bill:

£3,312 – £1,500 = £1,812 annual savings go to our Shanks’ Pony jockey at 2026 prices.

(I’ll do the top-end of TI’s range first, then come back.)

Round two

Calculate the saving in 1996 prices. Or rather outsource the task to the Bank of England via its excellent inflation calculator.

£1,812 in May 2026 = £877.46 in 1996.

Okay, so horseless carriage hater TI would have trousered £877.46 some 30 years ago with his strap-hanging ways.

Round three

How much then would TI be sitting on now if he’d committed the inflation-adjusted equivalent of £877.46 per year for 30 years into a global tracker fund?

£74,298.77 at 1996 prices

That number comes from dividing the annual saving by 12 to get a monthly contribution of £73.12.

Compound that by 6.06% for 30 years.

6.06% is the 30-year real annualised return of the MSCI World GBP.

The final round

Now we have to pump up £74,298.77 to 2026 prices to goggle at the size of TI’s treasure chest in today’s money.

£74,298.77 in 1996 is worth £153,429.98 in May 2026.

Or, if TI’s low-ball £1,000 annual costs are accurate: £195,774.30.

Post-match analysis

It’s not quite the jackpot The Investor imagined. On the other hand, who would say no to an extra £150,000 to £200,000 in their account?

Driving is the norm in the UK so few people are likely to consider designing a lifestyle that squeezes it out.

But what if a wizened savings sensei told your younger self that a tidy six-figure sum was at stake?

Maybe they could make it work?

Take it steady,

The Accumulator

Bonus caveats

The Accumulators’ costs are shared between two. In theory that means TI’s savings are only worth half as much per person in a two-person, single-car household.

Then again, if TI diverted the dosh into his pension pot he’d earn tax relief unavailable to the rubber-burning Accumulators.

TI’s commuting costs were low to minimal for most of his life but so were The Accumulator’s. Let’s say that balances out.

There surely is a premium to pay for living in an area well served by public transport. (On the other hand, if you own your home then TI would argue it’s an investment.)

But you may be able to offset that outlay some other way. Perhaps you can dispense with having a garden, or living near great schools, or some other ‘must-have’ lifestyle choice that, for you, just isn’t.

TI would also likely claim a health benefit over most drivers – because his favoured mode of transport is his own fine pins.

FIRE in the whole

The compounded number is much less impressive if you’re dashing for FIRE in ten years. However, the money will continue to compound for so long as you’re saving.

One way to look at it in those circumstances is to divide the saving by your sustainable withdrawal rate, then subtract that amount from your target figure.

For example, car savings of £1,500 per year enable you to reduce your FIRE number by:

£1,500 / 0.04 = £37,500 (Assuming a 4% withdrawal rate.)

How dependable is the investing route?

Inflation-adjusted equity returns can vary a great deal – even over 30 years.

The current 30-year real annualised range is 2.4% to 9.9% (1900-2025). The mean average is 5.7%.

For the record

Finally, my full list of car-related expenses includes:

Maintenance (repairs, service, MOT)
Taxes (car tax, drivers’ licence renewal, registration fees)
Petrol
Parking
Fines (2023 was a bad year)
Cost of the next car (£1,000 per year)

Right to reply by TI

The Investor here…

Okay, I hope we’ve all had our fun, but I’m commandeering the reins – perks of the publishing button – to add a final bit.

When we discussed this piece, I asked gas-guzzling petrolhead The Accumulator to include a nod to typical car ownership costs in his attempt to ~~ridicule~~ substantiate my six-figure savings claims.

Looking back, it was a poor sign that he shouted something back down the line about not being able to hear me as Mrs TA had the hairdryer on and by the way he was “off on a mini-break, starting now, bon voyage!” before terminating the call.

So for the record, the latest Pension Living Standard’s report puts ‘motoring’ costs in the range of £4,000 to £5,000 a year.

That’s for typical retirees, remember, not for wannabe Jeremy Clarksons.

Moreover it’s easy to find estimates – such as this one from breakdown cover specialist AutoHome – that put the annual cost of a car in the £5,000 to £8,000 ballpark, all-in.

Now I’m not going to second-guess TA’s figures, nor gainsay his frugality.

I’ve waited too many times in vain at the bar for that – coughing and waving an empty pint glass around while TA has taken an unusually deep interest in his shoes / WhatsApp messages / something in the distance a few centimetres above my head.

So yes, as a globally recognised titan of the FIRE movement, TA’s numbers should look good! And no doubt those following in his footsteps can keep their costs down, too.

But I still stand by my benchmarking against the average car owner, not a savings ninja. That’s what we do when we’re weighing up other FIRE lifestyle choices, after all.

Not owning a car saved me a fortune. Albeit at the cost of some friends’ patience, surely.
