Marital status affects car insurance rates at most major insurers, with married drivers paying roughly 15% less than single drivers for the same coverage, according to a Consumer Federation of America analysis of six of the largest U.S. carriers.1Consumer Federation of America. New Research Shows That Most Major Auto Insurers Vary Prices Considerably Depending on Marital Status How much your own premium moves when you marry, divorce, or lose a spouse depends heavily on which company you’re with and which state you live in. A few states restrict the practice; most don’t.
How Big the Gap Actually Is
The size of the married-versus-single price difference varies sharply by carrier. CFA found that Farmers charged single, separated, and divorced drivers an average of 22% more than married drivers for identical coverage. Progressive’s gap averaged 19%. Nationwide came in at 9%, Liberty Mutual at 8%.1Consumer Federation of America. New Research Shows That Most Major Auto Insurers Vary Prices Considerably Depending on Marital Status State Farm was the only major insurer in the sample that charged the same rate regardless of marital status.
GEICO’s pricing was the most unpredictable of the group. In some cities, the single-driver surcharge was slight; in others, it was dramatic. The gap also doesn’t close with age. When CFA ran the same comparison for a 50-year-old sample driver, the price differences between married and single drivers persisted at most companies.1Consumer Federation of America.

Why Insurers Price This Way
Insurance companies price policies by grouping drivers who look similar on paper and predicting how often that group files claims. Their internal data shows married drivers file fewer claims involving high-speed collisions and impaired driving, and insurers treat marriage as a proxy for lifestyle stability.
The marital discount by itself is often modest. One estimate puts it around 5% just for being coupled.2United Policyholders. Divorce and Auto Insurance: Splits Boost Cost The larger savings come from what marriage usually makes possible alongside it: putting two cars on one policy and bundling auto with homeowners or renters coverage. Those stacked discounts do most of the work.
What Changes When You Get Married
Combining two drivers onto a single household policy typically triggers a multi-car discount, generally in the 8% to 25% range depending on the carrier. Bundling that policy with homeowners or renters coverage through the same company can shave another 10% to 25% off. Add the marital status adjustment on top, and the combined effect on a household’s premiums can be substantial.
Your spouse’s record comes with them. Marrying someone with a clean driving history improves the overall risk profile the insurer uses to price your policy. If your spouse has accidents or violations, your combined premium can go up instead of down. Insurers rate every driver on the policy, not just the primary name on it.
Your Spouse’s Credit Can Move the Price Too
Most states let insurers use credit-based insurance scores when setting premiums. When you move to a joint policy, a spouse’s poor credit can lift the price even if their driving record is clean. California, Hawaii, Massachusetts, and Michigan prohibit insurers from using credit information in auto pricing, so this isn’t a concern in those states.3Massachusetts Division of Insurance. Massachusetts Consumer Bill of Rights for Automobile Insurance Everywhere else, it’s worth looking at both credit profiles before combining policies.
Telling Your Insurer
Contact your carrier to update your marital status within 30 days of the wedding. Most companies require a legal marriage certificate to apply the married rate. Living together, even for years, generally won’t qualify. If you and your spouse have different last names, the insurer may specifically ask for marriage documentation to verify eligibility.
What Happens After Divorce
Divorce usually unwinds the savings that marriage created. The marital rate goes away, and splitting into separate policies strips out the multi-car discount, which on its own can run from 10% to 20%.2United Policyholders. Divorce and Auto Insurance: Splits Boost Cost Combined with losing the marital rate, newly divorced drivers often see noticeable premium jumps.
What forces the split isn’t always the divorce decree. For most insurers, what matters is where each vehicle is parked overnight. If one spouse moves out and keeps their car at a new address, the vehicles need to be on separate policies whether or not the divorce is final. If both cars still sleep at the same address during a separation, the shared policy may be able to continue for the time being.
Each driver also loses the combined purchasing power of a household account. Without the other spouse’s vehicles and bundled coverage attached, each person has to qualify for the insurer’s minimum premium alone. The hit people underestimate isn’t one discount disappearing; it’s several at once.
Remove your ex from the policy promptly once the split is in motion. If they cause an accident while still listed on your account, it can affect your rates and claims history.
What Happens When a Spouse Dies
Widowed drivers face increases similar to those after divorce, despite the entirely different circumstances. CFA found that four of six major insurers raised rates for widowed drivers by an average of 20% on mandatory liability coverage.1Consumer Federation of America. New Research Shows That Most Major Auto Insurers Vary Prices Considerably Depending on Marital Status Across all six carriers, the average increase for widowed drivers was 14%, with GEICO averaging a 29% increase and Farmers 22%.
State Farm again charged widowed drivers the same rate as married ones. Nationwide raised rates for widows only in certain cities. The spread across carriers means shopping after a spouse’s death can matter a great deal: the same driver might pay 29% more at one company and nothing extra at another.
Domestic Partnerships and Unmarried Couples
Whether you qualify for a marital-type discount without a marriage certificate depends on your insurer and your state. Most carriers require either a legal marriage certificate or a state-recognized domestic partnership to apply the married rate. Couples who live together without any formal legal arrangement generally don’t qualify, no matter how long the relationship has lasted.
If your state recognizes domestic partnerships or civil unions, your insurer may extend the same discount, but it isn’t guaranteed. Insurance companies are not legally required to treat domestic partnerships identically to marriages for rating purposes in most states. Ask your carrier directly whether they recognize your partnership and what proof they need. A domestic partnership registration certificate is typically the minimum.
Common-law marriage adds complication. Only a small number of states still recognize it, and proving it to an insurer without a certificate can be difficult. Some form of official documentation makes the process considerably smoother.
States That Restrict the Practice
A few states limit or prohibit insurers from using marital status in auto pricing, but fewer than most people assume. Massachusetts is the clearest example. The state explicitly prohibits insurance companies from using sex, marital status, race, religion, age (except for a senior discount), occupation, income, education, or homeownership as rating factors.3Massachusetts Division of Insurance. Massachusetts Consumer Bill of Rights for Automobile Insurance
California takes a different route. Under Proposition 103, auto insurance rates must be set primarily by three factors in order of importance: driving safety record, annual miles driven, and years of driving experience. Any additional rating factor must be approved by the insurance commissioner and must have a “substantial relationship to the risk of loss.”4California Legislative Information. California Insurance Code 1861.02 That framework limits the role marital status can play, though the statute doesn’t name it as a prohibited factor.
Hawaii prohibits insurers from refusing to continue a policy based solely on marital status, among other factors.5Justia Law. Hawaii Revised Statutes 431-10C-111 – Cancellation and Refusal to Continue That protection covers cancellation and nonrenewal rather than initial pricing, so it’s narrower than a full rating ban.
Montana used to broadly prohibit the use of sex and marital status across insurance lines, but repealed that ban through HB 379 in 2021, and the repeal was later upheld in court.6Montana Commissioner of Securities and Insurance. State Auditor James Brown Successfully Defends the Constitutionality of HB 379 Montana insurers can now use marital status in pricing.
Outside these states, your marital status is fair game.
How to Soften a Rate Change
Whether you’re getting married, divorced, or dealing with a spouse’s death, a few steps can limit the premium swing:
- Shop aggressively after any status change. The CFA data shows the penalty varies wildly between companies. State Farm charges the same rate regardless of status; Farmers and GEICO impose some of the steepest surcharges. Getting quotes from at least three carriers after a divorce or widowhood is the single most effective move.
- Keep bundling where you can. Even after a divorce, pairing your own auto with renters insurance at one company preserves part of the multi-policy discount you’d otherwise lose.
- Review who’s listed. After a divorce, confirm your ex-spouse is removed from the policy promptly to avoid their incidents affecting your record.
- Ask about behavior-based discounts. Defensive driving courses, low-mileage discounts, and telematics programs that track actual driving can partially offset the loss of a marital discount. In states that restrict demographic rating factors, these programs carry extra weight.
- Check your credit. In most states, your credit-based insurance score matters as much as or more than marital status. Cleaning up credit issues during a divorce, when joint accounts are being separated, can prevent a second premium hit on top of the status change.
Marital status is one lever among many, and its impact ranges from zero at some companies to more than 20% at others. Knowing which carriers penalize your status most heavily is what keeps you from overpaying.
