How the $1,680 splits
- $1,050 Primary Card
- $630 Secondary Card
Or, without paying: a higher limit
About $18,667 more in total credit limit, on Primary Card, would bring your overall ratio into the 1–9% range with no payment. Secondary Card would still be above it, because a higher limit on one card does not change another card’s ratio. It only helps if the new limit is not spent.
Most issuers report the balance on your statement closing date, so a payment made before that date is usually the one that counts.
Why there is no score estimate here
Neither FICO nor Experian publishes how many points a score moves when utilization changes, so this calculator does not estimate one. FICO says keeping utilization below 10% can help build and maintain a good score. Experian describes 30% as the point where the effect becomes more pronounced, and says the exact impact depends on your current score, the scoring model and the rest of your credit report.
With $8,000 in total credit limits and a $2,400 balance, your utilization is 30.0%. Keep utilization under 30% for good credit; 1–9% is ideal for top scores. Credit utilization is the second most important factor in your FICO score (30% of the calculation).

Understanding Credit Utilization
What is Credit Utilization?
Your credit utilization ratio is the percentage of your available credit that you're currently using. It's calculated by dividing your total credit card balances by your total credit limits.
Why Ratio Beats Total Debt
Owing $500 on a $1,000 limit (50% utilization) hurts your score more than owing $2,000 on a $10,000 limit (20% utilization), even though the dollar debt is higher.
Statement Date Matters
Your balance is reported on your statement closing date, not your due date. Paying down balances before the statement closes lowers your reported utilization.
Why Closing Cards Hurts
Closing a credit card reduces your total available credit, which can increase your utilization ratio even if your balances stay the same.
Understanding Credit Score Factors
Your credit score is a three-digit number that represents your creditworthiness to lenders. The most widely used scoring model is the FICO Score, which ranges from 300 to 850. Understanding what affects your credit score can help you take targeted actions to improve it and qualify for better interest rates on loans and credit cards.
The 5 Credit Score Factors
FICO scores are calculated using five categories of information from your credit report. Each factor carries a different weight in determining your overall score:
| Factor | Weight | What It Measures |
|---|---|---|
| Payment History | 35% | On-time payments, late payments, collections |
| Credit Utilization | 30% | How much of your available credit you're using |
| Length of Credit History | 15% | Age of your oldest and newest accounts |
| Credit Mix | 10% | Types of credit accounts you have |
| New Credit | 10% | Recent credit applications and inquiries |
Payment History (35%)
Payment history is the most important factor in your credit score. Lenders want to know if you pay your bills on time because past behavior predicts future behavior.
What affects payment history:
- On-time payments — Every payment made by the due date helps build positive history
- Late payments — Payments 30+ days late are reported to credit bureaus and damage your score
- Severity of lateness — 30 days late is less damaging than 60, 90, or 120+ days late
- Collections and charge-offs — Unpaid debts sent to collections severely hurt your score
- Bankruptcies and foreclosures — These stay on your report for 7–10 years
| Lateness | Score Impact | Time on Report |
|---|---|---|
| 30 days late | -60 to -110 points | 7 years |
| 60 days late | -70 to -120 points | 7 years |
| 90+ days late | -80 to -150 points | 7 years |
| Collection account | -50 to -150 points | 7 years |
| Bankruptcy | -130 to -240 points | 7–10 years |
Credit Utilization (30%)
Credit utilization measures how much of your available revolving credit you're using. It's calculated by dividing your credit card balances by your credit limits. The calculator above helps you determine your current utilization ratio.
Key utilization thresholds:
- 1–9% — Excellent: Shows responsible use without over-reliance on credit
- 10–29% — Good: Generally considered healthy credit behavior
- 30–49% — Fair: May signal higher risk to lenders
- 50–74% — Poor: Indicates potential financial stress
- 75%+ — High Risk: Significantly hurts your score
Credit scoring models look at both your overall utilization across all cards AND the utilization on each individual card. Having one maxed-out card can hurt your score even if your overall utilization is low. Aim to keep each card below 30% utilization.
Strategies to lower utilization:
- Pay down balances — The most direct way to reduce utilization
- Request credit limit increases — Higher limits lower your ratio (without increasing spending)
- Pay before statement closes — Balance at statement close is what gets reported
- Make multiple payments per month — Keep balances low throughout the billing cycle
- Keep unused cards open — Closing cards reduces available credit and raises utilization
Length of Credit History (15%)
Longer credit history generally means better scores because it gives lenders more data to assess your reliability. This factor considers:
- Age of oldest account — How long you've had credit
- Age of newest account — Recent accounts lower your average age
- Average age of all accounts — The key metric (aim for 7+ years)
- Account activity — How long since you used certain accounts
Tips for building credit history:
- Keep old accounts open — Even if you don't use them often, old accounts boost your average age
- Don't open too many new accounts at once — This lowers your average account age
- Become an authorized user — Being added to a parent's or spouse's long-standing account can help
- Start early — Consider a secured credit card or student card to begin building history
Credit Mix (10%)
Credit mix refers to the variety of credit accounts you have. Lenders like to see that you can manage different types of credit responsibly.
Types of credit:
- Revolving credit — Credit cards, store cards, lines of credit (variable balance)
- Installment loans — Mortgages, auto loans, personal loans, student loans (fixed payments)
- Open credit — Charge cards that require full payment each month
While having a healthy credit mix helps, don't open accounts you don't need just to improve this factor. Credit mix is only 10% of your score, and unnecessary debt can backfire. Focus on payment history and utilization first.
New Credit (10%)
Opening several new accounts in a short period represents greater risk to lenders. This factor tracks:
- Hard inquiries — When lenders check your credit for applications (stays 2 years, impacts score for 1 year)
- Soft inquiries — Background checks, pre-approvals, checking your own credit (no impact)
- New accounts opened — Recent accounts can temporarily lower your score
| Inquiry Type | Examples | Score Impact |
|---|---|---|
| Hard Inquiry | Credit card applications, loan applications, apartment rentals | Typically fewer than 5 points per inquiry (per FICO) |
| Soft Inquiry | Checking your own credit, pre-approval offers, employer background checks | No impact |
When shopping for mortgages, auto loans, or student loans, multiple inquiries within a 14–45 day window (depending on the scoring model) count as just one inquiry. This allows you to compare rates from multiple lenders without hurting your score. The FICO model uses a 45-day window for rate shopping.
Credit Score Ranges
Understanding where your score falls helps you know what rates and terms to expect:
| Score Range | Rating | What to Expect |
|---|---|---|
| 800–850 | Exceptional | Best rates, highest approval odds, premium card offers |
| 740–799 | Very Good | Excellent rates, easy approvals, most products available |
| 670–739 | Good | Competitive rates, standard approval process |
| 580–669 | Fair | Higher rates, limited options, may require deposits |
| 300–579 | Poor | Difficulty qualifying, high rates, secured products only |
How to Improve Each Factor
Focus your efforts based on each factor's weight:
| Factor | Quick Wins | Long-Term Strategies |
|---|---|---|
| Payment History (35%) | Set up autopay, payment reminders | Build 12+ months of on-time payments |
| Credit Utilization (30%) | Pay before statement closes, request limit increase | Pay down debt, keep utilization under 10% |
| Credit History (15%) | Keep old cards open, become authorized user | Maintain accounts for 7+ years average |
| Credit Mix (10%) | Consider credit-builder loan if needed | Naturally diversify over time |
| New Credit (10%) | Space out applications, use rate-shopping window | Only apply for credit you need |
Payment history (35%) and credit utilization (30%) together account for 65% of your FICO score. If you're working to improve your credit, prioritize making every payment on time and keeping your credit card balances low. These two actions will have the biggest impact on your score.
Frequently Asked Questions
A good credit utilization ratio is generally under 30%. However, for the best credit scores, experts recommend keeping utilization between 1–9%. Lower utilization demonstrates responsible credit management to lenders.
While 0% utilization is not harmful, having 1–9% utilization typically shows active, responsible credit use and may be viewed more favorably than complete inactivity. Using your cards occasionally and paying them off demonstrates good credit habits.
Changes to your credit utilization ratio typically appear on your credit report within 1–2 billing cycles after your card issuer reports the new balance. Credit score improvements can happen as soon as the lower utilization is reflected in your report.
Both matter! Credit scoring models look at your overall utilization across all cards and the utilization on each individual card. It's best to keep both your overall ratio and individual card ratios below 30%.
How This Calculator Works
This calculator divides your total revolving balances by your total credit limits to get your overall utilization percentage, and repeats the same balance-over-limit division for each card you enter to find your per-card utilization. FICO and VantageScore both weigh utilization as a share of your credit score, so the calculator also compares your ratio against commonly cited score-impact bands published by the credit bureaus. It does not pull your real balances or limits — every result depends only on the numbers you type in.
The plan under “What would it take?” works two ways. For a target, each card pays its balance minus the target share of its limit, and nothing if it is already there; the plan is the sum of those payments, which is never less than the overall ratio alone would need. “Under 30%” plans to 29.9% and “1–9%” plans to 9%, so the result reads the way its name says on this page. For a fixed amount, the money always goes to the card whose ratio is highest at that moment, so the cards that are paid end at the same ratio. Payments for a target are rounded up to the cent. The limit-increase figure is your total balance divided by the target, minus your total limit. The plan does not estimate a score change.
