Does My Spouse’s Credit Score Affect Mine?

Your credit score won’t be affected by simply marrying someone with good or bad credit, but there are scenarios where their credit behavior can affect your credit score and your ability to get a mortgage.

Tying the knot often means tying your finances to your spouse’s. And while there isn’t a direct link between your spouse’s credit score and your credit score -- you won’t have bad credit just because your spouse does -- there are some cases where bad credit management by one spouse can negatively affect the credit score of the other spouse.

Below, I’ll explain the ins and outs of credit scores, ways in which your spouse’s credit can affect yours, and how your spouse’s credit can affect your personal finances in ways beyond just your credit score.

Intro to credit scores

The way to think about credit scores is that they are a “grade” based on the information in your credit report. Credit scoring companies look at what’s on your credit report, and based on that information -- your payment history, your existing balances, credit mix, and so on -- they calculate a numerical value. A FICO® Score can range from 300 to 850, with higher numbers being better.

Here’s a quick guide to the five parts of your credit score:

  • Payment history (35% of your score) -- Do you always pay your bills on time? It’s really that simple. Your most recent payment history will have more impact than old payment history. For example, a 30-day late payment that happened five years ago won’t matter much at all, but a 30-day late payment three months ago can be devastating to your credit.

  • Credit utilization (30%) -- This is based on how much credit you’ve used as a percentage of how much credit you could use. If you have a $1,000 balance on a $5,000 credit card, and it’s your only financial account, then your credit utilization is 20%, which is just fine. Using more than 30% of your credit limits is a warning sign to lenders, and can harm your credit score.

  • Length of credit history (15%) -- Someone who has 15 years of perfect credit history is probably a better risk than someone who has just six months of perfect credit history.

  • New credit (10%) -- Applying for a large number of loans or credit accounts in a short period of time can hurt your credit score because it’s something people often do when they are having financial problems that haven’t yet shown up in their credit reports.

  • Types of credit (10%) -- Having a mix of revolving accounts (credit cards) and installment debt (mortgages, car loans, personal loans, student loans, etc.) is better than having just one type of account, but this factor isn’t that important, and you shouldn’t borrow money just to get a different type of account on your credit report.
