One of the most important things to understand in motor insurance is that IDV is not static. It changes as the car gets older. If you do not track that change, renewal quotes can feel arbitrary even when they follow a clear depreciation pattern.
You can estimate that year-by-year movement with the car insurance IDV calculator.
The rule used on this site
This site uses a simple pattern:
- first year or new car: 5 percent lower than ex-showroom price
- second year onward: 10 percent lower than the previous year's IDV
That means the reduction compounds over time.
Why this year-by-year view matters
If you only look at the current premium, you miss the bigger picture. The car is aging, the insured value is changing, and your policy comparison should account for that. Looking at the schedule year by year helps you understand whether the quote is broadly in the range you expect.
Example of how value changes
For a car with an ex-showroom price of Rs 10,00,000:
- year 1 IDV: Rs 9,50,000
- year 2 IDV: Rs 8,55,000
- year 3 IDV: Rs 7,69,500
- year 4 IDV: Rs 6,92,550
The drop is not a flat amount each year because it is being calculated from the previous year's IDV.
Common misunderstanding
Many people expect depreciation to be calculated from the original car price every year. But if you are using a rule based on the previous year's IDV, the path is compounding instead.
That is why it helps to use a proper schedule rather than rough mental math.
How to use the schedule during renewal
At renewal time, review:
- the age of the car
- the estimated IDV for that age
- the premium being quoted
- any add-ons such as zero-depreciation
This lets you compare the insured value with the rest of the policy package more clearly.
Final takeaway
IDV changes with car age, and the pattern can be easier to understand when you look at it year by year. If you want a quick estimate for a new or old car, use the car insurance IDV calculator and review the schedule before comparing renewal options.
