Beyond the numbers
The maths shows one side. These are the things only you can weigh.
- Reliability and peace of mindA new car comes with a warranty and a known history. Fewer surprise breakdowns can matter a lot if the car is needed every day.
- Safety featuresNewer models often have better safety equipment. For a family car, that may outweigh the numbers.
- Knowing the historyA used car with a full service record and an independent inspection is a much safer buy than one without.
- The pleasure of newChoosing the colour, being the first owner and the new-car feeling are real joys. Only you can say what they are worth.
- Time and hassleFinding a good used car takes effort, and repairs take time. Some people would rather pay to avoid that.
How it's calculated
Both households start with the same money. Money not spent grows at your assumed return. Comparing what each owns at the end, the car plus savings, shows the true cost of each choice.
Assumptions
- Values fall by a steady yearly rate; real resale prices vary with model, condition and demand.
- Upkeep and insurance are yearly amounts paid at the end of each year.
- Fuel, registration, loans and selling costs are not included unless added to the running costs.
- Money saved grows at a steady yearly return.
Worked example
A 10 lakh rupee new car losing 15% a year and costing 40,000 rupees a year to keep, against a 6 lakh rupee used car losing 10% a year and costing 60,000 rupees: after 5 years, with savings at 8%, the used car ends about 3.81 lakh rupees ahead. The new car would then be worth about 4.44 lakh and the used car about 3.54 lakh.
Questions
Why does the new car fall behind?
Because a new car loses the most value in its first few years, and the extra money spent on it could have been saved instead.
When does a new car make sense in the numbers?
When the used car would need much more upkeep, loses value quickly, or the price gap is small. Try those values to see.
Should I include fuel?
Only if the two cars use noticeably different amounts. Add the yearly difference to the running cost of the thirstier car.
What about a loan?
If either car is bought on a loan, add the yearly interest to its running costs, or use the car cash or loan page alongside this one.
