NCB in Car Insurance — What It Is, How to Calculate & How to Protect It in 2026

Your No Claim Bonus (NCB) is the most valuable discount in motor insurance — and most car owners don't fully understand it. Over 5 claim-free years, NCB can save you up to 50% on premium. Here's everything you need to know.

What is No Claim Bonus (NCB)?

NCB is a reward from your insurer for not making any claims during a policy year. For every claim-free year, you earn a progressively higher discount on your Own Damage (OD) premium at renewal. It's essentially your insurer rewarding you for being a safe, careful driver.

NCB applies only to the Own Damage component of comprehensive insurance — not on third party premium (which is fixed by IRDAI).

How Much Can You Save with NCB?

Claim-Free YearsNCB DiscountSaving on ₹10,000 OD Premium
1 year20%₹2,000/year
2 years25%₹2,500/year
3 years35%₹3,500/year
4 years45%₹4,500/year
5+ years50%₹5,000/year

Over 5 claim-free years on a ₹10,000 OD premium, the total NCB savings add up to approximately ₹17,500 in cumulative discounts. This makes NCB the single most valuable long-term benefit in motor insurance.

⭐ Real Example

Rohit in Pune has a 5-year-old Honda City with a base OD premium of ₹9,800. After 5 claim-free years, his NCB is 50%, meaning he pays only ₹4,900 in OD premium — saving ₹4,900 every single year.

Key NCB Rules You Must Know

How to Protect Your NCB

Option 1: NCB Protection Add-on

This add-on, available with most comprehensive policies, allows you to make one specified claim per year without losing your NCB. It typically costs 5-8% of the OD premium — so roughly ₹400-800/year on a ₹10,000 premium. Strongly recommended if your NCB is 35% or above.

Option 2: Pay Small Claims Out of Pocket

If the claim amount is small (under ₹15,000-20,000), it may make more financial sense to pay from your pocket and preserve your NCB. Calculate whether the claim amount is less than the NCB discount you'd lose — if yes, don't claim.

Option 3: Renew on Time, Every Time

Set a reminder 30 days before your policy expiry. Never let it lapse beyond 90 days. This is the single most important rule to protect your NCB.

How to Transfer NCB to a New Car

When you sell your old car and buy a new one, you can transfer your accumulated NCB. Here's how:

  1. Get an NCB Certificate from your current insurer (valid for 3 years)
  2. When insuring your new vehicle, submit this certificate to the new insurer
  3. Your NCB discount will be applied on the new vehicle's OD premium
⚠️ Important

NCB cannot be transferred between two simultaneously owned vehicles or transferred to another person. It strictly belongs to the individual policyholder and moves with them to their new vehicle.

Frequently Asked Questions

Does NCB reset to zero if I make a claim?
Yes, under a standard policy, any claim resets NCB to 0% at the next renewal. However, if you have the NCB Protection add-on, you can make one specified claim per year without losing your accumulated NCB.
Can I transfer NCB from one insurer to another?
Yes! NCB is portable across insurers. When switching insurers at renewal, request an NCB certificate from your current insurer and submit it to the new one. They are obligated to honour it.
What happens to NCB if I don't renew my policy?
If you fail to renew within 90 days of expiry, your accumulated NCB is permanently lost. You start from 0% with the new policy. This is one of the most expensive consequences of a policy lapse.
Is NCB Protection worth buying?
Absolutely, if your NCB is 35% or above. At 35% NCB on a ₹10,000 premium, you're saving ₹3,500/year. The NCB Protection add-on costs only ₹400-800/year. One claim without it would wipe out ₹3,500 in annual savings — making the add-on extremely cost-effective.
