Calculating Auto Insurance: A Quick Guide To The 10% Rule

The 20/4/10 rule of thumb is a general guideline for car buyers to determine whether they can afford a car. It suggests that you can afford a car if you meet the following three requirements: put down a 20% down payment, take out a car loan with a term of four years or less, and keep your total transportation costs to less than 10% of your monthly income. This rule helps ensure that you can afford the down payment, limit the interest you pay by paying off the loan relatively quickly, and keep your car from dominating your budget. However, it is not a one-size-fits-all solution and may not work for everyone, especially those with limited incomes or those just starting their financial journey.

10/20/10 insurance: the maximum an insurance company will pay out per accident

10/20/10 insurance is a type of auto insurance policy that represents the limits on your liability coverage. These numbers are the maximum that an insurance company will pay out per accident, in tens of thousands of dollars. In other words, the policy covers up to $10,000 per person for bodily injury, $20,000 total for bodily injury, and $10,000 for property damage.

The first number, $10,000, is the maximum amount that the insurance company will pay out per person for bodily injury. This means that if you injure someone in an accident, your insurance company will pay up to $10,000 for their medical bills. If the injured person's medical bills exceed $10,000, you will be responsible for paying the additional costs out of pocket.

The second number, $20,000, represents the total limit on bodily injury claims. This means that if multiple people are injured in an accident, the insurance company will pay up to a maximum of $20,000 for all the claims combined. For example, if two people are injured in an accident, each person could recover up to $10,000, exhausting the policy limits. If three people are injured, any one of them could recover up to $10,000, and the remaining $10,000 would be shared between the other two people.

The third number, $10,000, is the maximum amount that the insurance company will pay for property damage in an accident. This includes damage to another person's vehicle or property. If you are at fault for an accident that results in damage to multiple vehicles, the $10,000 limit may not be sufficient to cover all the damages, and you may have to pay additional costs out of pocket.

It is important to note that 10/20/10 insurance is the minimum amount of coverage required by most states for registering and legally operating a vehicle. However, this level of coverage may not be adequate in the event of a major accident, especially if multiple people are injured or there is significant property damage. Therefore, it is recommended to purchase a higher level of coverage if possible, such as 100/300/50, to ensure sufficient protection.

Down payment: 20% down on a car with a four-year loan

A down payment of 20% on a car with a four-year loan is a good rule of thumb to follow when buying a new car. This rule of thumb is based on the size of your down payment, the length of your loan term, and the percentage of your income that goes towards transportation costs.

• 20% Down Payment: Aim to make a 20% down payment on your new car. A larger down payment will lower the overall amount you borrow and reduce the interest you'll pay over the life of the loan. It will also reduce the likelihood of owing more on the car than it is worth, also known as becoming upside down on your car loan.
• 4-Year Repayment Term: Choose a repayment term of four years or less on your auto loan. A shorter-term car loan will result in higher monthly payments but will save you money in interest in the long run. By limiting the length of your loan term, you will avoid spending more on interest over time and own your car sooner.
• 10% Transportation Costs: Keep your total transportation costs, including auto loan payments, car insurance, fuel, and repairs, to 10% or less of your monthly income. In 2022, US households spent an average of $12,295 on transportation. Keeping your transportation costs below 10% will help you afford unexpected costs and stay within your budget.

Lucy wants to buy a new car and has $500 saved up for a down payment. Her current car is paid off and has a trade-in value of $2,000.

Calculate a 20% Down Payment:

• Down payment = $2,000 (trade-in value) + $500 (savings) = $2,500
• Down payment x 5 = $2,500 x 5 = $12,500 maximum car-buying budget

Choose a 4-Year Loan Term:

Lucy chooses a 48-month loan at a 5% interest rate for her new car.

Figure Out 10% Transportation Costs:

• Lucy's monthly income is $4,200.
• Transportation costs should be kept below $420 ($4,200/10) per month.

By following the 20/4/10 rule, Lucy can make a financially sound decision when buying her new car, ensuring she doesn't overspend on a depreciating asset.

It is important to note that this rule of thumb may not work for everyone and should be adjusted based on individual financial situations.

Monthly income: spend no more than 10% of your monthly income on transportation costs

The 20/4/10 rule is a common guideline that can help you calculate whether you can afford your ideal car. The rule suggests that you can afford a car if you meet the following three requirements:

• You can make a down payment of 20% or more when purchasing the car
• You can take out a car loan with a term of four years or less
• You can keep your total transportation costs—not just your car loan—to less than 10% of your monthly income

This rule can help you in multiple ways. Firstly, it ensures that you can afford a down payment on the car. This is important because new cars begin to depreciate as soon as you drive them off the lot. Secondly, a four-year car loan can help you limit the interest you pay because you'll pay off the loan relatively quickly. Finally, keeping your total transportation costs to less than 10% of your monthly income can help ensure that a car doesn't dominate your budget and leaves room for other expenses.

For example, if your monthly salary is $4,000, then you should spend no more than $400 on transportation. This includes car payments, insurance, and fuel.

It's important to note that this rule is just a guideline and may not fit every person's situation. You may decide to spend more or less on a car depending on your values and financial situation. Additionally, this rule doesn't take into account all situations, such as car enthusiasts who are willing to spend more on a car and reduce their spending on housing.

When applying this rule, it's recommended that you use your best judgment and consider your individual circumstances. For instance, if you cannot afford to replace your car, dropping collision insurance could leave you stranded or in debt. Similarly, if you have a history of at-fault accidents or a teenager learning to drive, you may need to keep collision insurance.

In general, this rule can help prevent you from overspending when purchasing a car. However, it may be seen as unreasonable by people on limited incomes or those just starting as adults. Adjustments may be needed to find a car that fits their needs and budget.

Insurance policy: when to change it

An insurance policy is a safety net that provides financial protection in the event of unforeseen circumstances. However, insurance needs can change over time, and it's important to review and update your policy to ensure it remains aligned with your evolving requirements. Here are some detailed guidelines on when to reevaluate and modify your insurance coverage:

Marriage or Significant Life Events:

Significant life events, such as getting married, relocating, or experiencing a change in employment status, are pivotal moments to reassess your insurance policy. Combining vehicle insurance policies with your partner or taking advantage of bundled home and car insurance plans can lead to significant savings. Additionally, updating your address with your insurer is crucial, as location plays a significant role in determining insurance rates.

Aging Vehicle:

As your car gets older, it may not be financially prudent to maintain comprehensive insurance coverage, especially if the vehicle's book value has significantly decreased. In such cases, reviewing and adjusting your policy can help ensure that you're not paying excessive premiums for an older vehicle.

Teenage Drivers:

Adding a teenage driver to your insurance policy can significantly increase premiums. However, it is generally more cost-effective to add them to your existing policy than to insure them separately. Many insurers offer discounts for teen drivers who maintain good grades or leave the family car at home while away at college.

Retirement:

Retirement often brings a change in driving habits, with seniors typically enjoying lower insurance rates due to reduced mileage. If you're retiring and will no longer be commuting daily, consider reviewing your policy to take advantage of low-mileage insurance options.

Dissatisfaction with Current Insurer:

While cost is a significant factor when switching insurance providers, it's not the only reason. If you're unhappy with the customer service or claims handling of your current insurer, it may be time to explore alternative options. Comparing insurance companies can help you find a provider that better meets your needs and expectations.

Changes in Income or Budget:

Your financial situation can fluctuate over time, and it's important that your insurance policy aligns with your budget. If your income has increased, you may consider enhancing your coverage or raising your deductible to maintain adequate protection. On the other hand, if your budget has tightened, reviewing your policy can help identify areas where you can cut back, such as dropping add-ons or adjusting coverage limits.

Open Enrollment or Special Enrollment Period:

For health insurance and certain other types of insurance, keep an eye out for open enrollment periods, which typically occur annually. During this time, you can freely change your insurance plan. Additionally, special enrollment periods may be triggered by specific life events, such as losing health coverage, moving, getting married, or having a baby. These periods provide an opportunity to reevaluate and change your insurance coverage.

Remember, while these guidelines offer a helpful structure, your unique circumstances should always be the primary driver when deciding to change your insurance policy. Regularly reviewing your coverage ensures that it remains responsive to your evolving needs and financial situation.

Car value: when your car is worth less than $3,000

When it comes to auto insurance, there are various factors that influence the cost, and the value of your car is one of the key considerations. If your car is worth less than $3,000, there are a few things to keep in mind when calculating your insurance needs and determining the right coverage for your vehicle.

Firstly, it's important to understand the different types of car insurance coverages available. The most basic coverages are bodily injury liability, property damage liability, collision coverage, and comprehensive coverage. Bodily injury liability covers the medical costs and lost wages of other drivers if you cause an accident, while property damage liability pays for damage to other people's property, such as another car or object. Collision coverage pays to repair your car after an accident, regardless of who is at fault, and comprehensive coverage takes care of repairs for damages caused by something other than a collision, like hail or vandalism.

When your car is worth less than $3,000, you may want to consider forgoing collision and comprehensive coverage, especially if your car is older. These coverages can be expensive, often doubling the cost of insurance, and may not be worth it for a less valuable vehicle. However, if you have a loan or lease on the car, you will likely need to maintain these coverages. Additionally, if you live in an area with severe weather conditions or high crime rates, comprehensive coverage could be beneficial to protect against weather-related damage or theft.

Another factor to consider is your state's minimum insurance requirements. Most states mandate bodily injury liability coverage and property damage liability coverage, with minimum limits ranging from $20,000 to $25,000 for bodily injury per person and $40,000 to $50,000 per accident, and $10,000 to $25,000 for property damage liability. Some states also require uninsured motorist coverage or personal injury protection (PIP). While these minimums provide a starting point, it's generally recommended to get as much liability insurance as you can afford to ensure adequate protection in the event of an accident.

When deciding on insurance coverage for a car worth less than $3,000, it's crucial to weigh factors such as the age of your car, your state's requirements, and your budget. While you may opt to forego certain coverages to save on costs, it's important to ensure you have sufficient liability coverage to protect yourself financially in case of an accident. Additionally, consider shopping around for quotes from multiple insurance companies and taking advantage of any available discounts to get the best rates for your needs.

In summary, when dealing with a car worth less than $3,000, carefully assess your specific circumstances, compare insurance options, and choose a coverage plan that balances cost and adequate protection for your vehicle.
