It’s hard to do anything in the 21st century without getting your credit involved. 

Buying a car? Your credit score will influence both the terms of your loan and your auto insurance premiums. 

Moving to a new apartment? Don’t be surprised if the leasing company runs a credit check. 

Starting a new job? Yes, even your employer might be interested in seeing your credit history before making an offer.

Whether you’re just starting to build credit for the first time or are hoping to rehabilitate your credit score, this guide to building credit has everything you need to know about the steps you’ll follow along the way. 

We’ll also show you how to protect your credit from potential negative effects brought on by the recent financial crisis surrounding COVID-19.

Understand Your Credit Report

If you’ve ever signed up for a credit card, bought a house, paid utility bills, or participated in the U.S. economy in any formal way, you have a credit report. 

A credit report is a deep dive into your history of paying bills and maintaining past and current accounts. It details the amount of debt you owe, to whom, how much has been paid back, and how effective you are at paying your bills. Also listed on your report: car insurance, apartment rentals, and retail credit card accounts. Lenders will use this information to determine how risky of an investment you are.

The details on your credit report also affect how your credit score is calculated. There are five main factors listed on your credit report. Each factor carries a different weight in terms of importance to lenders and its influence on your score, which is expressed in a three-digit number between 300 and 850. 

1. Payment history. Paying your creditors on time and in full is the most weighted factor in your credit report; it accounts for 35% of your total credit score. If your payment history includes late or insufficient payments, this will appear on your credit report as a derogatory mark.

2. Balances owed. Your total debt determines another 30% of your credit score. This includes your credit utilization ratio and other factors, such as the number of accounts that have balances. 

3. Age of credit history. A long history of making consistent payments is a positive sign to lenders, which is why the length of your credit history is included in your credit report. The longer your accounts have been open, the better they look on your report. This factor accounts for 15% of your credit score.

4. Credit mix. Lenders like to see a mix of three types on your credit report as proof you’ve used various types of debt responsibly. The mix of different account types determines 10% of your credit score. The three types of credit are installment credit, revolving credit, and open credit.  

5. Recent activity. The final 10% of your credit score looks at how much new credit you have taken on recently. If you open too many accounts in a short time, it may signal you’re experiencing financial difficulty, and your score will be negatively affected.

Know The Difference Between a Credit Score and Credit Report 

Your credit report records your history of credit use while outlining your effectiveness as a borrower. The information on your credit report will then be used to determine your three-digit credit score

The three major credit bureaus — Experian, Equifax, and Transunion — gather the information from your credit report. But your credit score is typically determined by FICO (Fair Isaac Corporation) which developed the most popular model for credit scoring. 

Both your credit score and credit report may be accessed by banks, auto lenders, mortgage lenders, credit card companies, collection agencies, insurance companies, rental agencies, utility providers, and landlords. One exception is employers, who can only access your report, not your score. Whether they can use your credit report in hiring decisions depends on which state you reside in; all employers that are able to use your credit report in hiring must get your consent to do so. 

What Are the Credit Bureaus and How Do They Work

You may already be familiar with the three credit bureaus: Experian, Equifax, and TransUnion. These reporting agencies formed throughout the 20th century as a way for merchants to share lists of customers who had failed to pay their debts. In 1970, the Fair Credit Reporting Act was signed into U.S. law, creating an official set of standards for credit reporting. The act mandated consumers were entitled to a free copy of their report once per year, a law which still exists today.

The credit bureaus function as data collection agencies that compile information on your credit activity into a report. Lenders can then access these reports and use them to gauge how risky you are as a borrower. With the information in a credit report, lenders decide whether or not to offer you credit and what interest rate you qualify for. This information typically includes your repayment history, current and past accounts, and whether you’ve been delinquent or filed for bankruptcy in the past several years. 

It doesn’t include things like parking tickets, tax liens, and civil judgments.

Why This Matters 

If credit scores and credit reports are separate entities, which should you check? Ideally both, but experts say you should start with your credit report, which you can now pull for free on a weekly basis through April 2021. “Because all of your credit scores are based on that information, the focus should, at the very least, be on your reports,” says credit expert John Ulzheimer, formerly of FICO and Equifax. But, Ulzheimer points out, “there are also numerous ways to get free scores, so there’s no reason to not remain engaged with both your scores and reports.”
