The primary rule of thumb for homeowners insurance is to insure your home for at least 80%—though 100% is recommended—of its replacement cost, not its market value or purchase price. This ensures full coverage for damages, as replacing a home (materials and labor) often differs from its selling price.
Full coverage isn't worth it when the annual cost of collision/comprehensive exceeds a significant portion (e.g., 10%) of your car's low market value, you have enough savings to replace or repair it out-of-pocket, or if you have a clear title and don't need it for work/family, while it's still required for leased/financed cars. Key factors include your car's depreciated value, your emergency fund, and your risk tolerance for paying for repairs/replacement yourself.
The 80% rule in homeowners insurance requires you to insure your home for at least 80% of its total replacement cost to receive full coverage for partial losses, preventing underinsurance and significant out-of-pocket costs if damaged; if you fall below this threshold, your insurer pays a proportionate amount of the claim, not the full repair cost. This rule ensures you can rebuild, factoring in current material and labor costs, but excludes land value.
Coverage limits of $250,000 / $500,000 (often written as 250/500) mean your auto liability insurance pays up to $250,000 for bodily injury to one person and up to $500,000 total for all people injured in a single accident, with a third number (e.g., $100,000) usually covering property damage (e.g., 250/500/100). This is a "split limit" policy, defining maximum payouts for specific injury/damage categories, leaving you personally liable for costs exceeding these amounts.
How much liability insurance do I need? Probably more than you think. Generally, we recommend $50,000/$100,000/$50,000 and for people who own a home the recommended amount is $100,000/$300,000/$100,000. Below are some rates for an insurance policy with liability limits set at 100/300/100.
The sum of the value of all your items is how much coverage you need. Often, the amount of personal property coverage is determined by using 50% of your dwelling coverage limit. For example, if your dwelling coverage is $400,000, you'll have $200,000 in personal property coverage.
When talking to a home insurance adjuster, do not admit fault, downplay damages or injuries, speculate on the cause, give recorded statements, or accept quick settlement offers, as these statements can be used to minimize your payout; instead, stick to basic, documented facts, avoid emotional language, and consider consulting an attorney before providing detailed information, even with your own insurer.
Dave Ramsey says homeowners insurance is crucial to rebuild your home and replace belongings, emphasizing guaranteed or extended replacement cost coverage to rebuild fully, even if costs exceed policy limits, alongside a high deductible to lower premiums; he stresses getting enough coverage to rebuild your house and stuff, not just its market value, and recommends using an independent agent for the best options.
If your annual collision premium costs more than 10% of what your vehicle is actually worth, you're probably at the point where dropping this coverage makes financial sense.
The "50% Rule" in insurance primarily refers to a Federal Emergency Management Agency (FEMA) regulation for flood-prone areas, stating that if repairs or improvements to a damaged structure exceed 50% of its pre-damaged market value, the entire building must be brought into full compliance with current flood elevation and construction codes. This rule, also known as the Substantial Damage/Improvement (SD/SD) rule, prevents properties from remaining in high-risk zones without mitigation, potentially affecting flood insurance eligibility if not followed.
You need comprehensive and collision if you have a car loan or lease, as lenders require it; otherwise, it's optional, but recommended if your car is valuable, you can't afford major repairs, or live in an area with high theft/weather risk, though you might drop it if the car's value is low and the cost of coverage outweighs potential repair costs. Collision covers accidents with objects/other cars, while comprehensive covers theft, vandalism, animals, and natural disasters.
What they won't tell you is that their primary job is to save their company money—often at your expense. Insurance adjusters are not your advocates. They're trained professionals whose performance is measured by how much they save their company. Every dollar you don't receive is a dollar their employer keeps.
8 Red Flags That Insurance Companies Aren't Going to Cover Your Bills
Many of the unique qualities in older homes also make them riskier to insure, which can lead to a higher rate and the need for specialized coverage.
The 80/20 rule in insurance refers to two main concepts: the Medical Loss Ratio (MLR) under the Affordable Care Act (ACA), requiring insurers to spend 80% (85% for large groups) of premiums on care or refund the rest, and a common home insurance clause where you must insure your home for at least 80% of its replacement cost to receive full coverage for partial losses, preventing underinsurance. In health insurance, it limits administrative costs and profits, while in homeowners insurance, it ensures adequate dwelling coverage to avoid penalties on claims.
Buildings insurance – this will pay for the repair or rebuilding of your house, in case there is major damage, such as a fire or falling tree. Contents insurance – this covers damage or loss of contents, such as furniture or jewellery, in the case of fire, theft or even accidents.
