What is the 80% rule in homeowners insurance?

The 80% rule in homeowners insurance is a guideline requiring you to insure your home for at least 80% of its total replacement cost to receive full coverage for claims, preventing coinsurance penalties that reduce payouts for underinsured homes, especially for smaller losses. Insuring for less than 80% means you'll bear a proportional share of the loss, even if the damage is minor, forcing you to pay out-of-pocket for a portion of repairs. It's crucial to update your policy for renovations or rising costs to meet this threshold.

What is the 80 20 rule in insurance?

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.

What does it mean if the coverage limits are $250000 / $500,000?

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.
 

At what point is full coverage not worth it?

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.
