Definition
Credit utilization is the percentage of your available credit that you're currently using across all your credit accounts. This ratio is calculated by dividing your total outstanding balances by your total credit limits, and it's one of the most important factors affecting your credit score—typically accounting for about 30% of your FICO score.
For example, if you have $5,000 in total credit card balances and $20,000 in total credit limits, your credit utilization is 25%. Financial experts generally recommend keeping your credit utilization below 30%, with under 10% being ideal for the best credit scores. This applies to both your overall utilization across all accounts and your individual account utilization on each credit card or line of credit.
Credit utilization is particularly important because it shows lenders how you manage available credit in real-time. Unlike payment history, which reflects past behavior, utilization demonstrates your current financial habits and debt management skills. High utilization can signal financial stress to lenders, even if you always make payments on time.
How It Applies to HELOCs
HELOCs function as revolving credit lines secured by your home, which means your credit utilization on a HELOC directly impacts your credit score just like credit cards do. During the draw period (typically 10 years), you can borrow and repay funds repeatedly, and your utilization will fluctuate based on your outstanding balance versus your credit limit.
For example, if you have a $100,000 HELOC and currently owe $30,000, your HELOC utilization is 30%. This gets reported to credit bureaus and affects your overall credit profile. Many homeowners don't realize that maxing out their HELOC—even for home improvements—can significantly hurt their credit score and make it harder to qualify for other loans or get the best rates on future financing.
How It Applies to DSCR Loans
For real estate investors, credit utilization becomes more complex when managing multiple properties and credit lines. DSCR lenders often look at your overall credit profile, including utilization across all accounts, when qualifying you for investment property loans. High credit utilization can signal overleveraging, which may concern lenders even when your rental income covers debt payments.
Investors who use HELOCs or business lines of credit to fund down payments or renovations need to carefully manage utilization timing. If you're planning to apply for a DSCR loan, consider paying down revolving balances beforehand to improve your credit profile. Some investors strategically time their credit utilization around loan applications, ensuring their credit reports show low balances when lenders pull their credit for new investment property financing.
Example Calculation
Sarah's Credit Utilization Calculation:
Sarah has the following credit accounts:
- Credit Card A: $2,500 balance / $10,000 limit
- Credit Card B: $1,200 balance / $8,000 limit
- HELOC: $25,000 balance / $75,000 limit
Step 1: Calculate total balances $2,500 + $1,200 + $25,000 = $28,700 total balances
Step 2: Calculate total credit limits $10,000 + $8,000 + $75,000 = $93,000 total limits
Step 3: Calculate overall utilization $28,700 ÷ $93,000 = 30.8% overall credit utilization
Individual account utilization:
- Credit Card A: $2,500 ÷ $10,000 = 25%
- Credit Card B: $1,200 ÷ $8,000 = 15%
- HELOC: $25,000 ÷ $75,000 = 33.3%
Sarah's overall utilization is slightly high at 30.8%, and her HELOC utilization of 33.3% could be impacting her credit score.
