Even smart people make insurance mistakes — from choosing the wrong policy to missing renewal dates. These errors cost Americans thousands of dollars each year in denied claims, coverage gaps, and overpayment.
This guide reveals the most common insurance errors and shows you how to fix them before they drain your wallet or leave you unprotected.
The eight most costly insurance mistakes are:
- Buying the wrong policy type for your needs
- Not comparing enough coverage options
- Choosing an unstable insurance company
- Ignoring premium increases at renewal
- Overpaying for unnecessary coverage
- Delaying or incorrectly filing claims
- Forgetting to renew your policy on time
- Never reviewing your plan after purchase
Each mistake is fixable. Read on to learn exactly how.
Mistake 1: Buying the Wrong Policy Type
You need life insurance, but buy term when you need whole life. You think collision coverage protects against theft (it doesn’t). You assume your health plan covers everything your old one did.
Buying the wrong type of coverage creates dangerous gaps. A 2024 study found that 40% of policyholders don’t fully understand what their insurance actually covers.
How This Hurts You
Wrong policy types mean denied claims when you need help most. You pay premiums for years, file a claim and then discover you’re not covered for that specific situation.
The Fix
Before buying any policy, avoid confusion by understanding your insurance type before choosing coverage. Ask your agent three questions:
- What exactly does this policy cover?
- What situations are NOT covered?
- Can you show me a real claim example?
Get answers in writing. If your agent rushes past these questions, that’s a red flag.
Mistake 2: Not Comparing Enough Options
You accept the first quote you receive. You renew automatically without shopping around. You assume all similar policies cost the same.
The same coverage can vary by $500 to $1,200 per year between insurers. Yet 60% of people never compare quotes before buying.
How This Hurts You
You overpay for identical coverage. Your neighbor with the same car and driving record might pay 30% less simply because they compared three companies instead of one.
The Fix
You can save big by comparing insurance plans easily before committing. Get at least three quotes for any insurance purchase. Make sure you’re comparing identical coverage limits and deductibles.
Check quotes every two years, even if you’re happy with your current insurer. Market rates change constantly.
Mistake 3: Choosing the Wrong Insurer
You pick the cheapest company without checking its reputation. You ignore financial stability ratings. You don’t research claim payment history.
Low premiums mean nothing if the company can’t pay your claim or makes you fight for every dollar.
How This Hurts You
Weak insurers delay claim payments for months. Some deny legitimate claims, forcing you to hire lawyers. Others go bankrupt, leaving you scrambling for new coverage.
The Fix
Finding the best insurance company helps you avoid future issues. Check these three things before signing:
- Financial rating — Only choose companies rated A or higher by AM Best
- Claim satisfaction — Read reviews from customers who actually filed claims
- Response time — Ask how quickly they process typical claims
A company charging 15% more but rated A+ beats a B-rated company offering the lowest price.
Mistake 4: Ignoring Renewal Increases
Your premium jumps $200 at renewal and you pay it without asking why. You don’t notice the $30 monthly increase. You assume rate hikes are normal and unavoidable.
Insurance companies count on autopay customers who never review renewal notices. These “silent increases” add up to thousands over time.
How This Hurts You
Unnecessary rate hikes drain your budget. Some increases are justified (you filed a claim, moved to a higher-risk area). Many are not.
The Fix
If your costs suddenly go up, it helps to know why insurance premiums rise. When you receive your renewal notice:
- Compare the new rate to last year’s
- Call and ask specifically why it increased
- Request available discounts you might qualify for now
- Get competing quotes if the increase exceeds 10%
Don’t accept vague answers like “market conditions.” Demand specifics.
Mistake 5: Overpaying for Coverage
You keep collision insurance on a 15-year-old car worth $2,000. You carry a $250 deductible when you have $10,000 in savings. You pay for coverage that duplicates protection you already have elsewhere.
Americans waste an estimated $400 to $600 annually on insurance they don’t need or that provides minimal benefit.
How This Hurts You
Money spent on unnecessary coverage can’t go toward building emergency savings or paying off debt. High premiums with low deductibles mean you’re prepaying for small losses you could easily afford.
The Fix
There are smart ways to save on insurance without cutting corners. Try these adjustments:
Drop These Coverages:
- Collision and comprehensive coverage on cars worth under $3,000
- Rental car insurance is included if your credit card includes it
- Life insurance on children (redirect premiums to your own policy)
Raise These Amounts:
- Increase deductibles to the highest amount you can comfortably pay from savings
- This alone can cut premiums 15-30%
Bundle These Policies:
- Combine home and auto with one insurer for 10-25% discounts
- Add an umbrella policy to existing coverage for cheap extra protection
Mistake 6: Delaying or Misfiling Claims
You wait three months to report damage, thinking you’ll fix it yourself. You throw away receipts and documentation. You accept the first settlement offer without question. You don’t follow the exact claim-filing procedures.
One in four insurance claim denials happens because of filing errors, missed deadlines, or incomplete documentation.
How This Hurts You
Late claims get denied outright. Missing documentation reduces your payout. Procedural mistakes give insurers grounds to reject legitimate claims.
The Fix
You can avoid rejections by filing an insurance claim correctly and on time. Follow this process:
Within 24 Hours:
- Report the incident to your insurer (even if you’re not sure you’ll file a claim)
- Take photos of all damage from multiple angles
- Get written estimates from repair shops
Within One Week:
- Submit your formal claim with all required documentation
- Keep copies of everything you send
- Get the claim number and adjuster contact information
Until Resolution:
- Respond to adjuster requests within 48 hours
- Document all phone conversations (date, time, person, what was said)
- Don’t accept the first offer if it seems low — get second opinions
Most policies require reporting within 30-90 days. Don’t miss that window.
Mistake 7: Forgetting Policy Renewal
Your coverage lapses because you missed the renewal deadline. Your payment method changed and autopay failed. You ignored renewal reminders ,thinking you had more time.
A lapse in coverage, even for a few days, can increase your rates by 10-20% when you reapply. Some insurers won’t take you back at all.
How This Hurts You
Driving, living, or going without health insurance while uninsured is illegal in most places and leaves you financially exposed. Reapplying costs more than simply renewing on time. Your new insurer sees the lapse and charges higher rates.
The Fix
Renewing your insurance policy on time keeps your coverage active. Set these reminders:
- Calendar alert 60 days before expiration
- Second reminder 30 days before
- Final warning one week before
Enable autopay, but check your account monthly to ensure the payment is processed. Update payment information immediately when you get a new card.
If you do lapse, contact your insurer the same day. Many offer grace periods if you act immediately.
Mistake 8: Not Reviewing Your Plan Yearly
You bought insurance five years ago and haven’t looked at it since. Your life changed — marriage, kids, new house, different job — but your coverage didn’t. You assume “set it and forget it” works for insurance.
Your insurance needs at 25 are completely different from your needs at 35 or 45. Outdated policies either waste money on coverage you don’t need or leave gaps in protection you do need.
How This Hurts You
You’re either overinsured (paying for protection that no longer applies) or underinsured (lacking coverage for new assets and risks). Either way, you’re making a costly mistake.
The Fix
Avoiding mistakes starts with choosing the right plan that truly fits your needs — and then keeping it updated.
Review every policy once per year, ideally 45 days before renewal. Ask yourself:
Life Changes:
- Did you get married, divorced, or have a child?
- Did you buy a home, car, or expensive possessions?
- Did your income increase or decrease significantly?
Coverage Changes:
- Does your home insurance reflect current rebuilding costs?
- Do your liability limits exceed your net worth?
- Have you accumulated assets not listed in your policy?
Cost Changes:
- Are you eligible for new discounts (good driver, security systems, bundling)?
- Can you raise deductibles now that you have more savings?
- Have you asked about loyalty discounts for long-term customers?
Schedule an annual “insurance review day” every January. Spend two hours checking all policies. This simple habit prevents expensive surprises.

FAQs
How long does it take to fix insurance mistakes?
Simple fixes like raising deductibles or adding discounts take 10-15 minutes with a phone call. Switching insurers takes 1-2 weeks. Fixing denied claims can take 30-90 days, depending on complexity.
Will shopping around hurt my insurance score?
No. Unlike credit checks, getting insurance quotes doesn’t impact your rates or score. Companies expect you to compare options and won’t penalize you for doing research.
What happens if I discover I’m underinsured after an incident?
You’ll pay the difference out of pocket. If your home needs $300,000 to rebuild but you only have $200,000 in coverage, you’ll owe $100,000. This is why annual reviews matter — fix gaps before disasters strike.
Can I cancel my policy if I find a better deal mid-term?
Yes, but you may owe a cancellation fee (typically $25-50). Calculate if your savings over the remaining months exceed the fee. Most people save enough to make switching worthwhile.
How do I know if an insurer is financially stable?
Check their AM Best rating (free on ambest.com). Look for A or A+ ratings. Avoid any company rated B+ or lower. Your state insurance department website also lists complaints and actions against insurers in your area.
