- FICO scores are the most widely used — 670+ is ‘good’, 740+ is ‘very good’, 800+ is ‘exceptional’.
- Payment history (35%) is the biggest factor — always pay at least the minimum on time.

What Is a Credit Score?
A credit score is a three-digit number that represents your creditworthiness — essentially, how likely you are to repay borrowed money on time.
In the United States, credit scores typically range from 300 to 850. The higher your score, the more trustworthy you appear to lenders.
Credit scores are used by:
- Banks and credit unions when approving loans
- Credit card issuers when setting your credit limit
- Landlords when reviewing rental applications
- Some employers during background checks
The most widely used credit scoring model in the U.S. is the FICO Score, developed by the Fair Isaac Corporation.
Credit Score Ranges
| Score Range | Rating |
|---|---|
| 800 – 850 | Exceptional |
| 740 – 799 | Very Good |
| 670 – 739 | Good |
| 580 – 669 | Fair |
| 300 – 579 | Poor |
Most lenders consider a score of 670 or above to be acceptable. Scores above 740 typically qualify for the best interest rates.
How Is a Credit Score Calculated?
Your FICO Score is calculated using five factors, each carrying a different weight.
1. Payment History (35%)
This is the most important factor. It tracks whether you pay your bills on time. A single missed payment can significantly lower your score.
2. Credit Utilization (30%)
This is the percentage of your available credit that you are currently using. For example, if your credit card limit is $5,000 and your balance is $1,500, your utilization rate is 30%.
Keeping your utilization below 30% is generally recommended.
3. Length of Credit History (15%)
The longer your credit accounts have been open, the better. This includes the age of your oldest account, your newest account, and the average age of all accounts.
4. Credit Mix (10%)
Having a variety of credit types — such as credit cards, auto loans, and mortgages — can positively impact your score. However, you should never take on debt just to improve your mix.
5. New Credit Inquiries (10%)
Every time you formally apply for credit, a hard inquiry is recorded. Multiple hard inquiries in a short period can temporarily lower your score.
Where Do Credit Scores Come From?
Your credit score is calculated based on information in your credit report, which is maintained by the three major credit bureaus in the U.S.:
- Equifax
- Experian
- TransUnion
Each bureau may have slightly different information, which means your score can vary slightly between them.

What Does NOT Affect Your Credit Score?
Many people are surprised to learn that the following do NOT affect your FICO Score:
- Your income or salary
- Your age
- Your employment status
- Your savings or bank account balances
- Soft credit inquiries (such as checking your own score)
How to Improve Your Credit Score
Improving your credit score takes time, but consistent habits make a significant difference:
- Pay every bill on time — set up automatic payments if needed
- Keep credit card balances low — aim for under 30% utilization
- Avoid opening too many new accounts at once
- Keep old accounts open — even if you don’t use them regularly
- Check your credit report for errors and dispute any inaccuracies
Frequently Asked Questions (FAQs)
How long does it take to build a good credit score?
Building a score above 670 typically takes 6 to 12 months of responsible credit use. Reaching 740 or above may take several years of consistent on-time payments and low utilization.
Does checking my score affect what is a credit score calculation?
No. Checking your own credit score is a soft inquiry and does not affect your score in any way.
Can I have a credit score with no credit history?
No. You need at least one open account that has been active for six months before a FICO Score can be generated. This is why building credit early is important.

Frequently Asked Questions
What is a good credit score?
FICO score ranges: 300–579 (Poor), 580–669 (Fair), 670–739 (Good), 740–799 (Very Good), 800–850 (Exceptional). For most financial goals — mortgages, car loans, credit cards with rewards — a score of 700+ is sufficient. 750+ gets you the best interest rates.
How long does it take to build credit from scratch?
You can establish a basic credit score within 3–6 months of opening your first credit account. Building a strong score (700+) typically takes 1–2 years of consistent on-time payments and responsible credit usage.
Does checking my own credit score hurt it?
No. Checking your own credit score is a ‘soft inquiry’ and does not affect your score. Only ‘hard inquiries’ — when a lender pulls your credit for a loan or credit card application — temporarily lower your score by a few points.
How can I build credit with no credit history?
Start with a secured credit card (you deposit money as collateral). Become an authorised user on a family member’s account. Apply for a credit-builder loan from a credit union. Make all payments on time and keep utilisation below 30%.
How many credit cards should I have?
There is no perfect number. Having 2–3 cards with low balances and on-time payments is generally positive for your score. More cards can help by increasing your total available credit (lowering utilisation), but only if you manage them responsibly.
