What Is NJM Insurance? A Century-Old Mutual With a New Reach
NJM Insurance Group was founded on June 7, 1913, as the New Jersey Manufacturers Casualty Insurance Company. It was created to write workers' compensation policies after New Jersey passed the Workmen's Compensation Act, which required employers to insure injured workers. The company added property, private auto, and commercial auto coverage in 1921, and by 1922 it was already the largest workers' comp provider in the state.
Headquartered in West Trenton, New Jersey since 1966, NJM employs roughly 2,500 people and operates as a true mutual insurance company. That structure matters. A mutual insurer is owned by its policyholders instead of outside shareholders, so profits either strengthen reserves or return to customers through dividends and low rates.
For decades, NJM was famously exclusive. You needed a connection to the New Jersey Education Association, a state agency, or a partner employer to get in. Today, that requirement is gone. Any qualifying resident of NJM's five personal-auto states can apply directly through the company's website.

Where NJM Is Available and Who Can Buy It
NJM currently sells personal auto, home, condo, renters, and umbrella insurance to residents of five states:
- New Jersey (original state)
- Pennsylvania (added 2018)
- Connecticut (added 2019)
- Ohio (added 2021)
- Maryland (added 2021)
NJM also writes workers' compensation and commercial auto in New York and Delaware, but those states are not eligible for personal car insurance. If you move outside NJM's footprint, you will need to shop for a new carrier from a state-approved list.
Eligibility is now straightforward: you need to be a resident of one of the five states, have a private-passenger vehicle, and meet standard underwriting criteria (driving record, prior insurance history, and, where legal, credit-based insurance score). NJM welcomes the general public, not just union members or specific employers.

NJM Auto Insurance Coverage Options
NJM offers the same core coverages you would expect from a major carrier, plus a few state-specific extras like PIP for no-fault New Jersey drivers. Available coverages include:
- Bodily injury and property damage liability
- Collision and comprehensive
- Uninsured and underinsured motorist
- Personal injury protection (PIP) and MedPay
- Rental reimbursement and roadside assistance
- Gap coverage on financed or leased vehicles
Through a partnership with American Modern Insurance Group, NJM policyholders can also insure motorcycles, ATVs, boats, and collector cars. The NJM SafeDrive telematics app is voluntary and tracks acceleration, braking, cornering, distracted driving, and speed. Uniquely, participation gives you a discount and NJM will not raise your rate based on SafeDrive data, even if you have an accident during the monitoring period.
How Much Does NJM Car Insurance Cost in 2026?
NJM is consistently one of the cheapest carriers in every state it serves, and the numbers back it up. In New Jersey, InsuranceQuotes.com's 2026 analysis found NJM's average full-coverage premium is $2,166 per year, roughly 40% below the $3,579 statewide average. U.S. News reports NJM at $2,355 annually versus a $3,268 New Jersey average, making it the second-cheapest insurer in the state.
Here is how NJM compares to the three biggest national carriers in New Jersey for 2026:
| Insurer | Minimum Liability (Annual) | Full Coverage (Annual) |
|---|---|---|
| NJM | $759 | $2,166 |
| Geico | $931 | $3,046 |
| Progressive | $1,158 | $2,642 |
| State Farm | $2,829 | $6,050 |
| NJ Average | $1,411 | $3,579 |
The gap widens when you have a recent at-fault accident. LendingTree's 2026 data shows NJM at $148/month after an accident, compared to $182 at Geico, $311 at Progressive, and $408 at State Farm. That is a real advantage if you have a blemish or two on your record.
NJM Dividends: A Perk Most Insurers Do Not Offer
Because NJM is a mutual company, New Jersey policyholders may be eligible for dividends. Dividends are calculated as a percentage of the premium paid on your previous policy term and are typically applied as a credit toward next year's premium. In some cases, NJM pays them by check.
Dividends are not guaranteed and the amount fluctuates based on NJM's financial results and board decisions, but the program has been a fixture for decades. Similar dividend perks exist at other mutuals like Amica Mutual, though NJM's dividends are currently limited to New Jersey drivers.
NJM Discounts
NJM's list of discounts is not the longest in the industry, but it is meaningful. Depending on your state, you may qualify for:
- Multi-car discount
- Multi-policy (bundling auto with home, renters, or umbrella)
- Pay-in-full and paperless / autopay discounts
- Good student
- Newer vehicle (two model years or less)
- Vehicle safety features (anti-lock brakes, passive restraints, anti-theft)
- Coverage-combination (buying both collision and comprehensive)
- Driver training (CT, MD, NJ, PA)
- Defensive driving course (New Jersey only)
- Accident prevention course for older drivers (CT, MD, OH, PA)
- NJM SafeDrive telematics participation
Bundling is one of the biggest wins. If you own a home, stacking your homeowners policy with auto typically produces the largest single discount. See our guide to bundling home and auto insurance for more strategies to squeeze savings out of a mutual insurer like NJM.
Customer Satisfaction, Claims, and Complaints
NJM has one of the strongest service reputations in the industry, particularly for a regional carrier.
- 2025 J.D. Power U.S. Auto Insurance Study (Mid-Atlantic): NJM ranked #1 with a score of 721 out of 1,000, sitting 65 points above the regional average.
- 2025 J.D. Power U.S. Auto Claims Satisfaction Study: NJM ranked #2 nationally with a score of 731, trailing only Erie Insurance at 743 and beating Liberty Mutual, State Farm, and every other major national carrier.
- Third-party recognition: NerdWallet named NJM its #1 car insurance company out of 24 insurers reviewed, with a full 5-star rating.
That claims record matters. J.D. Power's methodology grades insurers on trust, fairness of settlement, time to settle, communication, and ease of resolving claims, so a #2 national score signals the process is not just fast, it is fair. If claims service is your top priority, also check our Erie Insurance review, which took first place in the same study.
Regulatory complaint data for NJM is not fully published for 2026 yet, but the company has historically posted below-average complaint ratios with state departments of insurance. High J.D. Power satisfaction scores typically correlate with fewer regulatory complaints.
Pros and Cons of NJM Car Insurance
NJM vs Geico, Progressive, and State Farm
Each of the three biggest national insurers has advantages, but NJM tends to win on price and claims service in the states it serves. Here is how the four stack up head to head.
Compared with Progressive's auto insurance, NJM typically prices lower for full coverage and after accidents, though Progressive has a more sophisticated telematics program (Snapshot) and the Name Your Price tool. Against State Farm's massive agent network, NJM offers dramatically lower rates in New Jersey (about $2,166 vs $6,050 annually for full coverage) but no in-person representation.
If you value the ability to walk into a local office, State Farm wins. If you want the lowest rates and best claims experience, NJM wins in every one of its states. For a broader comparison of the biggest national carriers, see our Geico car insurance review and our Travelers review.
Frequently Asked Questions
Is NJM car insurance good?
Yes. NJM ranked #1 in the Mid-Atlantic in the 2025 J.D. Power Auto Insurance Study and #2 nationally for auto claims satisfaction, ahead of every large national carrier except Erie. It also holds strong financial ratings and consistently posts below-average complaint ratios. For residents of its five personal-auto states, NJM is one of the best options available.
Do you have to be a teacher or state employee to get NJM?
No. NJM used to require membership in the New Jersey Education Association or affiliation with certain employers, but that restriction has been eliminated. Any qualifying resident of New Jersey, Pennsylvania, Ohio, Maryland, or Connecticut can apply for a personal auto policy directly through the company.
How much does NJM car insurance cost?
In New Jersey, NJM averages about $2,166 per year for full coverage and $759 for minimum liability in 2026, according to InsuranceQuotes.com.

Does NJM pay dividends to auto policyholders?
Yes, but only in New Jersey. New Jersey NJM policyholders may receive a dividend calculated as a percentage of their previous term's premium.
