When to use this calculator
- When you need a fast estimate before making a bigger decision.
- When you want to compare a few scenarios using the same assumptions.
- When you need a clearer starting point before using a detailed quote or formal document.
- When you want to sanity-check a figure you have seen elsewhere.
A realistic Australia planning example
Use these sample inputs as a quick scenario test, then change one variable at a time to compare outcomes.
| Input | Value |
|---|---|
| Current Value (A$) | A$1,400 |
| Annual Depreciation (%) | 5% |
| Years | 5 years |
After entering these figures, review value after {years} years and lost together rather than in isolation. Then rerun the tool with one input adjusted.
How to read your results
Value After {years} Years
The figure produced by this output for the inputs you entered. Change one variable at a time if you want to see what drives it.
Lost
The figure produced by this output for the inputs you entered. Change one variable at a time if you want to see what drives it.
Method & assumptionsAuthoritative sources
This calculator estimates how much value your car is likely to lose over time using a declining-balance depreciation model, which more accurately reflects real-world used car pricing than a simple straight-line approach. You enter the purchase price, estimated annual depreciation rate, and the number of years you plan to own the car. The calculator does not factor in mileage, condition, regional market variations, or sudden shifts in demand (such as those affecting diesel cars after emissions regulations tightened). Treat the result as a planning guide rather than a precise valuation. For a current market value, tools such as CAP HPI or Parkers provide data-driven used car pricing specific to your registration.
Common mistakes
- !Using an assumption that is not supported by a current local quote, bill, statement or official source.
- !Treating a generic estimate as a lender, provider, payroll or tax authority decision.
- !Mixing monthly and annual inputs without converting them consistently.
- !Testing only one scenario instead of checking how a cautious assumption changes the result.
What to do next
- Run a second scenario with a cautious assumption so you can see the downside clearly.
- Compare the result with the related calculators below before making a decision.
- Check current local rules, eligibility and provider terms before applying or committing money.
- Keep a record of the assumptions so you can update the estimate when a quote, bill or pay figure changes.
