Renewing Car Insurance Is a 10-Minute Decision That Costs or Saves You ₹3,000-12,000 Every Single Year.
Most car owners auto-renew. Their agent calls, quotes a number, they pay. No comparison, no IDV check, no add-on review. This convenience costs the average car owner ₹5,000-8,000 annually in overpayment.
The renewal window is the one time each year you control your motor insurance costs. Miss it, and you either overpay or underinsure. This guide covers the exact 9-point checklist to follow before clicking “renew.”
The 9-Point Car Insurance Renewal Checklist
1. Start 15 Days Before Expiry — Not the Last Day
IRDAI recommends renewing 15 days before expiry. The new policy automatically starts from the old policy’s end date — there is no overlap or double-payment.
Why 15 days matters:
- Time to compare 5-10 insurer quotes
- Time to switch insurers if a better deal exists
- Time to research which add-ons you actually need this year
- Zero risk of accidental lapse
If you wait until the last day, you accept whatever your current insurer quotes. That is not renewal — that is autopay with extra steps.
2. Check Your Current NCB — It Is Your Biggest Discount
NCB (No Claim Bonus) applies only to OD premium, but at 50%, it halves your OD cost.
| Your Current NCB | New NCB at Renewal (if claim-free) | Annual Savings on ₹18,000 OD |
|---|---|---|
| 0% (new policy) | 20% | ₹3,600 |
| 20% (1 year) | 25% | ₹4,500 |
| 25% (2 years) | 35% | ₹6,300 |
| 35% (3 years) | 45% | ₹8,100 |
| 45% (4 years) | 50% | ₹9,000 |
| 50% (5+ years) | 50% (max) | ₹9,000 |
Where to find your NCB: Check the policy schedule document, call your insurer’s helpline, or look at the renewal notice email/SMS.
If you filed a claim last year, your NCB resets to 0%. Factor this into your renewal budget — your premium will jump significantly.

3. Verify Your IDV — The Number That Determines Your Payout
IDV (Insured Declared Value) is the maximum your insurer pays on total loss or theft. Most people never check it.
The IDV trap at renewal:
- Insurer defaults to minimum allowed IDV (saves them money on claims)
- You see a lower premium and think you got a discount
- Your car is stolen — payout is ₹1-2 lakh less than market value
How to set the right IDV:
- Check your car’s resale value on Cars24, OLX, or CarDekho
- Compare with the insurer’s quoted IDV
- If the gap exceeds ₹50,000, increase IDV to match market value
| Car | Age | Default IDV (Insurer) | Market Resale Value | Gap You Lose on Theft |
|---|---|---|---|---|
| Maruti Swift VXI | 3 years | ₹4,20,000 | ₹5,30,000 | ₹1,10,000 |
| Hyundai Creta SX | 2 years | ₹10,50,000 | ₹12,00,000 | ₹1,50,000 |
| Honda City V | 4 years | ₹5,80,000 | ₹7,00,000 | ₹1,20,000 |
The premium cost of correct IDV is ₹1,000-3,000/year. The claim cost of wrong IDV is ₹1-2 lakh. The math is not close.

4. Compare Quotes Across 5+ Insurers (Set Identical Parameters)
Since OD was detariffed in 2007, every insurer sets its own OD pricing. The spread is massive.
Real example — Hyundai Creta SX 2023, Delhi, 35% NCB, identical IDV and add-ons:
| Insurer | OD Premium | TP Premium | Total (incl GST) |
|---|---|---|---|
| ACKO | ₹9,200 | ₹7,897 | ₹20,174 |
| Go Digit | ₹10,800 | ₹7,897 | ₹22,063 |
| ICICI Lombard | ₹12,400 | ₹7,897 | ₹23,951 |
| New India Assurance | ₹14,100 | ₹7,897 | ₹25,957 |
| Bajaj Allianz | ₹11,500 | ₹7,897 | ₹22,889 |
Spread: ₹5,783 between cheapest and most expensive — for the same car, same city, same coverage.
Critical rule: Set identical IDV and identical add-ons before comparing. A cheaper quote with lower IDV is not a discount — it is less insurance.
Use PolicyBazaar, InsuranceDekho, or Coverfox to compare 15-20 insurers in one search.
5. Buy Online — Skip the Agent Commission
Agent commissions on motor insurance range from 10-25% of OD premium. Since IRDAI removed fixed commission caps in 2024 (shifted to principle-based framework), this range has widened.
What the agent commission costs you:
| OD Premium | Agent Commission (15-25%) | Your Annual Overpayment |
|---|---|---|
| ₹8,000 | ₹1,200-2,000 | ₹1,200-2,000 |
| ₹15,000 | ₹2,250-3,750 | ₹2,250-3,750 |
| ₹25,000 | ₹3,750-6,250 | ₹3,750-6,250 |
Online purchase eliminates this entirely. Digital insurers (ACKO, Digit) have no agent channel — their pricing reflects zero commission overhead. Aggregator platforms show direct-from-insurer pricing.
The only value an agent adds is hand-holding during claims. Digital insurers now handle claims through apps, WhatsApp, and dedicated helplines — often faster than agent-assisted claims.
6. Review Your Add-On Stack — What to Keep, What to Drop
Add-ons should change as your car ages. The stack that made sense for a new car is wrong for a 4-year-old car.
| Add-On | Car Age 0-3 Years | Car Age 3-5 Years | Car Age 5+ Years |
|---|---|---|---|
| Zero Depreciation | Keep (₹1,500-4,000/yr) | Keep if available | Usually unavailable |
| Engine Protect | Keep (₹500-1,500/yr) | Keep | Limited availability |
| RTI (Return to Invoice) | Keep (₹500-1,500/yr) | Marginal value | Skip (IDV too low) |
| NCB Protector | Keep if NCB ≥35% | Keep | Keep |
| RSA (Roadside Assistance) | Skip if under warranty | Maybe (₹300-800/yr) | Maybe |
| Consumables Cover | Keep (₹300-700/yr) | Keep | Keep |
| Tyre Protect | Skip | Skip | Skip |
Annual add-on review saves ₹1,000-3,000 by dropping what no longer provides value.

7. Consider Voluntary Deductible — But Do the Math
Voluntary deductible reduces your OD premium but increases your out-of-pocket per claim.
| Voluntary Deductible | OD Discount | Max Discount Cap | Break-Even Claims |
|---|---|---|---|
| ₹2,500 | 20% | ₹750 | Worth it if <1 claim/2 years |
| ₹5,000 | 25% | ₹1,500 | Worth it if <1 claim/3 years |
| ₹7,500 | 30% | ₹2,000 | Worth it if <1 claim/4 years |
| ₹15,000 | 35% | ₹2,500 | Worth it if <1 claim/6 years |
The hidden catch: Discount percentages look attractive, but IRDAI caps the rupee savings. A ₹15,000 deductible on a ₹12,000 OD premium saves only ₹2,500 — not ₹4,200 (35%). And every claim now costs you ₹15,000 out of pocket plus ₹1,000-2,000 compulsory deductible.
Best strategy for most: ₹2,500 voluntary deductible saves ₹750/year with minimal claim impact. Higher deductibles only make sense for premium SUVs with OD above ₹20,000.

8. Check if Your Zone Changed
IRDAI divides India into Zone A (8 metros: Delhi, Mumbai, Chennai, Bengaluru, Kolkata, Hyderabad, Ahmedabad, Pune) and Zone B (everywhere else).
Zone A OD premiums are 10-15% higher than Zone B due to higher accident frequency, theft rates, and repair costs.
If you relocated:
- Zone B → Zone A: Your premium will increase. Update your address — failing to do so risks claim rejection.
- Zone A → Zone B: Your premium should decrease. Update your address and save 10-15% on OD.
- Different state: Get NOC from current RTO, re-register vehicle, then renew with updated RC.
TP premium is the same nationwide — zone only affects OD.
9. Factor in the 18% GST
Every rupee of premium, every add-on, every rider attracts 18% GST. This is non-negotiable and often forgotten when budgeting.
| Pre-GST Premium | GST (18%) | Total You Pay |
|---|---|---|
| ₹15,000 | ₹2,700 | ₹17,700 |
| ₹20,000 | ₹3,600 | ₹23,600 |
| ₹30,000 | ₹5,400 | ₹35,400 |
No income tax deduction is available for personal car insurance GST. It is a pure cost. This makes every premium-saving decision above more impactful — the savings compound by 18%.
Renewal Timeline: What to Do When
| Days Before Expiry | Action |
|---|---|
| 30 days | Receive renewal notice from current insurer. Note your NCB percentage. |
| 15-20 days | Compare quotes from 5+ insurers. Set identical IDV and add-ons. |
| 10-15 days | Decide: renew with current insurer or switch. If switching, gather NCB documents. |
| 7 days | Purchase the new policy online. New policy auto-starts from old policy expiry date. |
| 0 days (expiry) | If you have not renewed, your car is uninsured from midnight. |
| 1-90 days after expiry | Can still renew but need break-in inspection. NCB retained. |
| 90+ days after expiry | NCB permanently lost. Break-in inspection mandatory. |
The ₹10,000/Year Renewal Mistake in Action
Scenario: Rajesh owns a 2022 Hyundai Creta (petrol, 1,497cc). He auto-renews through his dealer’s agent every year without comparing quotes.
| Factor | Rajesh (Auto-Renew) | Smart Renewal |
|---|---|---|
| IDV | ₹9,20,000 (insurer default) | ₹10,80,000 (matched to market) |
| OD Premium | ₹16,200 | ₹11,400 (cheaper insurer) |
| Agent Commission | ~₹2,400 (15%) built-in | ₹0 (online) |
| Unnecessary RSA Add-On | ₹600 (has manufacturer RSA) | ₹0 (dropped) |
| NCB Applied | 35% (correct) | 35% (correct) |
| Total Premium (incl GST) | ₹31,152 | ₹22,771 |
| Annual Overpayment | ₹8,381 | — |
| Payout Gap on Total Loss | ₹1,60,000 less (lower IDV) | — |
Rajesh pays ₹8,381 more per year AND gets ₹1.6 lakh less on a total-loss claim. Over 5 years, that is ₹42,000 in excess premium plus ₹1.6 lakh in claim risk.
TP Premium Hike Alert: 2025-2026
Third-party premiums have been frozen for 4+ years. IRDAI has proposed an 18-25% increase. MoRTH may cap it at 10%. Either way, your TP component will rise at your next renewal.
| Engine Capacity | Current TP | After 10% Hike | After 25% Hike |
|---|---|---|---|
| ≤1,000cc | ₹2,094 | ₹2,303 | ₹2,618 |
| 1,001-1,500cc | ₹3,416 | ₹3,758 | ₹4,270 |
| >1,500cc | ₹7,897 | ₹8,687 | ₹9,871 |
You cannot avoid TP hikes — they are IRDAI-mandated. But you can offset them by optimizing your OD premium using the 9 steps above.

Bottom Line
Car insurance renewal is not a formality. It is a ₹20,000-35,000 annual financial decision. The 9 checks above take 30 minutes and save ₹3,000-12,000 every year — without reducing your coverage by a single rupee.
Renew early. Compare always. Buy online. Check your IDV. Protect your NCB. That is the entire playbook.
