Full Coverage vs Liability Auto Insurance: Which One Saves You More Money?
When shopping for auto insurance, one of the biggest questions drivers ask is:
Should I choose full coverage insurance or liability insurance?
At first glance, liability insurance looks cheaper, while full coverage insurance seems expensive. But does cheaper always mean better? And which type of insurance actually saves you more money in the long run?
In this detailed guide, we’ll explain full coverage vs liability auto insurance in simple words, using real-life examples. By the end, you’ll clearly know which insurance option fits your budget, car, and lifestyle in 2025.
What Is Auto Insurance? (Quick Refresher)
Auto insurance is a contract between you and an insurance company. You pay a monthly or yearly premium, and in return, the insurance company helps pay for damages, injuries, or losses after an accident or covered event.
In the U.S., auto insurance is not optional — most states legally require at least liability insurance. But many drivers choose full coverage insurance for extra protection.
What Is Liability Auto Insurance?
Liability insurance is the most basic and legally required type of auto insurance in most states.
What Liability Insurance Covers
Liability insurance pays for:
- Injuries to other people
- Damage to other people’s property
- Legal costs if you’re sued after an accident
It does NOT pay for:
- Damage to your own car
- Your medical bills
- Theft, fire, or weather damage
Types of Liability Coverage
- Bodily Injury Liability – Covers medical expenses, lost wages, and legal fees for others
- Property Damage Liability – Covers repairs or replacement of the other person’s car or property
Why Liability Insurance Is Cheaper
Because liability insurance offers limited protection, insurance companies charge lower premiums. This makes it attractive for drivers on a tight budget.
Average Cost of Liability Insurance (2025)
In 2025, the average liability auto insurance cost in the USA is roughly:
- $600–$900 per year
- Around $50–$75 per month
Costs vary based on:
- State requirements
- Driving record
- Age
- Vehicle type
Liability insurance is clearly the cheapest insurance option upfront — but cheap doesn’t always mean cost-effective.
What Is Full Coverage Auto Insurance?
Full coverage insurance is not a single policy. It’s a combination of multiple types of insurance coverage.
What Full Coverage Insurance Includes
✔ Liability insurance
✔ Collision coverage
✔ Comprehensive coverage
Some policies also include:
- Medical payments coverage
- Uninsured/underinsured motorist insurance
- Roadside assistance
What Full Coverage Insurance Covers
- Damage to your car after an accident
- Theft or vandalism
- Fire, flood, hail, storms
- Hit-and-run accidents
- Collisions with animals
In short, full coverage insurance protects both you and your car.
Average Cost of Full Coverage Insurance (2025)
In 2025, the average full coverage auto insurance cost is approximately:
- $1,800–$2,300 per year
- Around $150–$190 per month
While full coverage insurance costs more monthly, it can save thousands of dollars after an accident.

Which Insurance Saves You More Money? (The Real Answer)
The truth is:
👉 The cheapest insurance is not always the one that saves you the most money.
Let’s break it down by situation.
When Liability Insurance Saves You Money
Liability insurance can be the smarter financial choice if:
🚗 You Drive an Older Car
If your car is worth less than $4,000, full coverage insurance may not be worth the cost. Insurance companies might total the car after a minor accident.
💸 You Want the Lowest Monthly Payment
Liability insurance keeps your monthly insurance bill low — helpful if money is tight.
🚦 You’re a Low-Risk Driver
If you drive very little and have a clean record, liability insurance might be enough.
🧰 You Can Afford Repairs
If you have savings to repair or replace your car after an accident, liability insurance could work.
Bottom line:
Liability insurance saves money upfront, but offers limited protection.
When Full Coverage Insurance Saves You Money
Full coverage insurance is often the better financial choice if:
🚘 You Own a New or Expensive Car
New cars are costly to repair or replace. Full coverage insurance protects your investment.
🏦 You Have a Car Loan or Lease
Lenders usually require full coverage insurance until the loan is paid off.
🌪 You Live in High-Risk Areas
If your area has high theft, flooding, or storms, comprehensive insurance can save you thousands.
🚑 You Want Peace of Mind
One accident without full coverage can wipe out years of savings.
Bottom line:
Full coverage insurance costs more monthly, but can prevent major financial loss.
Real-Life Cost Example
Let’s compare two drivers:
Driver A: Liability Insurance
- Pays $65/month = $780/year
- Gets into a $6,000 accident
- Pays $6,000 out of pocket
Driver B: Full Coverage Insurance
- Pays $170/month = $2,040/year
- Same accident
- Insurance covers repairs (minus deductible)
👉 Driver B saves thousands of dollars, even with higher premiums.
How Insurance Deductibles Affect Savings
A deductible is what you pay before insurance kicks in.
- Higher deductible = lower insurance premium
- Lower deductible = higher insurance premium
Choosing the right deductible can make full coverage insurance more affordable.
Tip:
Many drivers save money by choosing a $1,000 deductible instead of $500.
How Insurance Companies Decide What You Pay
Insurance companies look at:
- Driving history
- Age and experience
- Location
- Credit history (in most states)
- Vehicle value
- Coverage type
Full coverage insurance costs more because it covers more risk.
Can You Switch Between Liability and Full Coverage?
Yes! Many drivers:
- Start with full coverage insurance
- Switch to liability insurance as their car ages
This is a smart insurance strategy and can save money over time.
Common Insurance Mistakes to Avoid
❌ Choosing liability insurance just because it’s cheaper
❌ Paying for full coverage on a car worth very little
❌ Not reviewing insurance annually
❌ Ignoring deductibles
❌ Skipping uninsured motorist insurance
How to Decide Which Insurance Is Best for You
Ask yourself:
- How much is my car worth?
- Can I afford repairs after an accident?
- Do I have a loan or lease?
- How much risk am I comfortable with?
Your answers will point you toward the right insurance choice.
Quick Decision Guide
- Choose Liability Insurance if:
✔ Your car is old

✔ Your car is new or valuable

Final Thoughts: Which Insurance Really Saves You More Money?
There’s no one-size-fits-all answer.
- Liability insurance saves money short term
- Full coverage insurance saves money after accidents
The best insurance decision balances cost, protection, and peace of mind.
If you’re unsure, compare insurance quotes side by side — many drivers are surprised how affordable full coverage insurance can be when discounts are applied.
