Spouses share a lot, but regardless of your relationship status, your credit score is yours and yours alone. Even if you are 100% financially supported by your spouse or partner, establishing and building your own credit score is essential.
It can benefit both of you as you navigate financial decisions together. But if you get divorced or your spouse dies, good or excellent credit can help you as you begin to make financial decisions on your own.
Also, maintaining some money independence can keep both of you on the same level in your relationship.
“Household financial dependence on a single income earner can foster unhealthy relationship control dynamics,” said Catherine Fox, a certified financial planner, founder and consultant at Sunnybranch Wealth in Portland, Oregon, in an email. “Stay-at-home spouses who take steps to protect their credit scores and financial literacy are doing their part to maintain healthy financial attitudes and dynamics in their relationship.”
Why your credit score is equally important
Whenever you and your spouse apply for a joint loan, such as a mortgage, both of your credit scores are evaluated by the lender. Lenders may use a person’s score that falls on the lower end to determine your eligibility. Ideally, the lowest score between the two of you is still in good standing as this can affect the terms of the loan, such as the interest rate, you qualify for together. A low credit score can make borrowing money more expensive.
Your credit score also comes into play when you apply for a credit card in your own name, which you can do even if you have no income. As long as you are 21 or older, you can include your spouse’s income on the card application.
Moreover, being single again unexpectedly is one of the most difficult reasons non-working spouses need to build their credit.
“Having a solid foundation will help if you’re single and need capital to get started,” says Brittany Davis, a certified financial advisor based in Memphis, Tennessee, who is an associate financial planner for Brunch & Budget, a registered investment advisor. “I know some people are pessimistic about credit and debt, but there are many things that credit can be used for.”
Davis compares credit access to insurance—it’s something that’s good to have, whether you need it now or not.

Even if you are not earning an income and your spouse is supporting you financially, it is important to build your own credit score. Not only will your score come into play when you apply for a joint loan, but you may need to fall back on it if you’re ever single again. You can build credit by using your spouse’s income on a credit card application or by becoming an authorized user on one of their cards and making on-time payments each month.

Ways to build credit without income
In addition to applying for your own credit card using your spouse’s income in your application, there are other ways to build your credit.
You can be an authorized user on your spouse’s credit card. They will be responsible for making the payments, but if they pay on time each month and you both avoid charging more than 30% of the credit limit, it can build your credit score over time. Applying for a loan under both of your names, such as an auto loan or mortgage, can also be helpful because on-time payments will be reflected on both of your credit reports.
“Very rarely, stay-at-home spouses should be joint account holders or have their spouse’s credit card added to them to help them build and maintain their own credit score,” says Fox.
Also ensure timely payment of utility bills and other household bills including rent payments. In some cases, it is also reported to the credit bureaus.
How you can affect each other’s credit scores
Although you each have your own credit scores, your money habits can help or hurt each other, especially when you have joint loans or share credit cards.
As a credit card authorized user, you are at the mercy of the behavior of the primary cardholder. If your spouse makes late payments, it can negatively affect your credit. You’ll want to set a budget with each other, because when more than one person uses the same card, it’s very easy to overspend. Becoming an authorized user is an exercise in trust and communication.
Where you live can also be a factor in how you can influence each other. According to Fox, in community property states, you are generally not responsible for any debts your spouse incurred before you were married, but you are responsible for each other’s debts after the marriage. But in non-community property states, you only share joint responsibility for accounts and debts.
And if you are the income earner, proceed with caution before co-signing a loan for your non-working spouse or other loved one. It is not like a joint loan, where both parties share the burden of paying the debt but may also share ownership of the assets.
“Co-signing is more risky in my eyes because you don’t have a secured interest in the item you’re co-signing the loan for,” says Davis. “If that person fails to pay, you become responsible for the loan, but as the owner you have no interest.”
How the credit scores of new auto loan borrowers have changed over the past 10 years
How the credit scores of new auto loan borrowers have changed over the past 10 years

Someone wants to lend you money. If they don’t know you, how will they know you can trust them to pay you in full? Commercial lenders look to credit scores to get a sense of your creditworthiness and calculate how likely you are to repay a loan on time. These cores are a way of measuring the risk associated with the lender lending you money.
A FICO score, one of the types of credit scores, is calculated by looking at your personal profile of your payment history, length of credit history, new credit and mix of credit accounts, which is a combination of the loans you have. Such as mortgages, student loans and credit cards.
When buying a car and getting an auto loan, it’s important to have a good credit score to get the most competitive interest rates from lenders. The exact rate will depend on many factors, including how much money you are borrowing, the terms of the loan and your lender. However, the scale here is clear: the lower your credit score, the more challenging it is to get a loan with a low interest rate.
For those who fit into the fair-to-low credit score range (699 or lower) or have a limited credit history, subprime auto loans are often the best or only option. “Subprime” means a borrower with a below-average credit rating. Subprime auto loans became big business from 2001-2004 as banks and other lenders became flush with cash and were willing to open up loan options to less-than-desirable borrowers. Strictly speaking, there is no official subprime auto loan rate, but it is usually 3-5 times higher than the prime loan rate. During the Great Recession of 2008, when consumer debt and defaults increased, particularly on mortgage debt, subprime loans in the housing market both contributed to and continued to fuel the financial turmoil. One result of the recession was an increase in subprime lending for auto loans.
RateGenius studied data from the New York Federal Reserve’s Quarterly Report on Household Debt and Credit to see how credit scores among auto loan borrowers have changed over the past 10 years. For this list, only credit scores from the fourth quarter of each year are included. According to the New York Fed, there were more than $733 billion in auto loan originations in 2021. As average credit scores declined following the Great Recession, scores have returned to primarily the range of the late 2000s.
Since 2012, the credit score of auto loan borrowers has increased nearly 2%, and during the first quarter of 2021, the average credit score of auto loan borrowers reached 720, a record high since the NY Fed began charting credit.
