See how much value your car loses each year: a declining-balance chart up to 10 years, a worked $24,000 example, and how to decide when to sell.

A car depreciation calculator estimates how much value a car loses over time and what it could be worth in future years. You enter a starting value and a time horizon, and you get a year-by-year picture of the decline. That matters because a car is usually the second-largest purchase a household or small business makes, yet its value falls every day.

Most owners only discover the size of that fall at the worst possible moment: at a trade-in desk, after an accident, or when a loan balance turns out to be higher than the car is worth.

How much value does a car lose in the first three years?

A new car typically loses the largest share of its value in its first three years, often around a fifth to a third of its original price, with the steepest drop in year one. That early fall is why a nearly-new used car can cost far less than the same model straight from the showroom.

The exact figure varies so much that generic averages are dangerous. A popular, reliable model with low mileage holds up far better than a rare model with high mileage and a patchy service history.

How does the declining-balance method work?

Under the declining-balance method, a car loses a percentage of its current value each year, not a fixed amount. Because the value it is calculated on shrinks every year, the cash amount lost gets smaller over time, even though the percentage stays the same.

A worked example: one hatchback, five years of falling value

Meet a fictional owner, Daniyal, who bought a new hatchback for $24,000 and wants to know whether to sell in year three or keep it until year five. The table below is an illustrative declining-balance estimate using a 15% annual rate, chosen only to show the shape of the curve.

Three lessons jump out. First, the car loses $3,600 in year one but only $1,879 in year five. Second, after five years Daniyal has lost about $13,350, roughly 56% of what he paid. Third, the gap between selling in year three ($14,739) and year five ($10,649) is about $4,090 — the real price of keeping the car two extra years, before running costs.

How to use the car depreciation calculator, step by step

The car depreciation calculator keeps the process deliberately short. There is no account form to fight through before you see a result, and no spreadsheet to build yourself.

1. Enter the purchase price or current value. Use what you paid when new for the full lifetime picture, or today's estimated value for the years ahead.
2. Set the car's age and how many years ahead to project. The chart runs for up to 10 years.
3. Read the year-by-year breakdown. You see the estimated value each year and the total value lost, so you can spot where the curve flattens.

Try more than one scenario: selling in one, three, and five years. Treat the chart as one input to the decision, not the whole decision, because insurance, servicing, and loan interest also matter. A budget calculator can help you weigh monthly running costs against the lump sum you keep by selling.

When should you check depreciation before deciding?

Depreciation is not a curiosity to check once. Checking it before you sell, buy, finance, or replace a vehicle usually saves money, because each of those decisions locks in a price or a loan based on a value that keeps falling.

• Selling or trading in: check the curve before you visit a dealer, so you know whether their offer is fair or a lowball.
• Buying used: a car that has already taken its biggest hit can be far better value than a nearly-new one at a small discount.
• Financing a purchase: if you borrow more than the car will be worth in two years, you risk owing more than it is worth. Run the numbers alongside a business loan calculator before signing, especially for a work vehicle.
• Running a small fleet: for delivery vans or sales cars, the replacement year is a business decision. Selling too late burns cash in repairs; selling too early throws away the cheap, flat part of the curve.

What a car depreciation calculator does not tell you

Honest limits matter here, because a neat chart can create false confidence. The calculator does not know your car's service history, accident record, tyre condition, or local market. It does not predict fuel prices, interest rates, or a sudden change in demand for your model, such as a manufacturer discontinuing it or a new electric model making older cars less attractive.

It also does not account for money you spend keeping the car running. For a business, the full picture is depreciation plus running costs plus downtime, which is why a break-even calculator is a useful companion when deciding whether a vehicle is actually paying its way.

Can you slow down how fast a car loses value?

You cannot stop depreciation, but you can soften it with choices that protect condition, mileage, and buyer confidence, and by timing the sale well. None of these turns a car into an investment, but together they can save hundreds or thousands at resale.

• Keep the service history complete: a stamped book with receipts removes the buyer's biggest fear and is worth real money at sale time.
• Control the mileage story: high annual mileage pushes a car down the curve fastest, so think twice before using a car you plan to sell soon for long daily commutes.
• Fix cosmetic damage early: small dents and kerbed wheels cost little to repair and disproportionately hurt first impressions.
• Time the sale: selling just before a major service, a new model launch, or a seasonal dip usually beats selling after it.

None of this turns a depreciating asset into an investment. It simply means you lose less of your money on the way out.

Frequently Asked Questions

How does car depreciation work?

Depreciation is the loss of a car's value over time. The car depreciation calculator uses a declining-balance method: the car loses a percentage of its current value each year, so the biggest losses happen early and the yearly drop gets smaller as the car ages.

How much value does a car lose each year?

There is no single rate that fits every car. Make, model, mileage, condition, and local demand all shift the figure, so testing your own car's numbers gives a more useful answer than a generic percentage.

What is a car depreciation chart?

It is a year-by-year table of a car's estimated value, from its price when new through each following year. The calculator generates this chart for your car's price and age, covering up to 10 years ahead.

Is the car depreciation calculator free?

Yes, it is free to use. You enter a price, an age, and a projection period, and you see the year-by-year breakdown and total value lost without building a spreadsheet.

Should I sell my car or keep it longer?

Compare the depreciation you avoid by selling now with the running costs and repairs of keeping it. If the car is in the flat part of its curve and running cheaply, keeping it often wins; if repairs are rising and value is still falling fast, selling sooner usually wins.

Does mileage matter more than age?

Both matter, and buyers weigh them together. A low-mileage older car and a high-mileage newer car can end up at similar prices, because mileage signals wear while age signals outdated features and remaining life.
