First of all, I want you to know this: what we call a credit score is actually an indicator of how much banks trust you. In Turkey, this score is maintained by the Findeks (Credit Bureau) system and is given a point between 1 and 1900. The higher your score, the easier banks open credit for you, interest rates decrease, and your credit card limits increase. In short, life becomes easier.
So how is this score calculated? Here are the factors that roughly affect it:
As you can see, the largest slice is payment history. In other words, whether you pay your debts on time comes before everything else. Now let's talk about each one individually.
📅 Never Delay Your Payments
The most critical rule, it determines 35% of your score alone.
The thing I need to tell you first is this: even a single late payment can seriously lower your credit score. Credit card payments, personal loan installments, phone bills, even an item you bought in installments from a shopping site... All of these are recorded.
The bank gives you a due date; when this date comes, pay at least the minimum amount. Of course, the ideal is to pay the entire debt, but if you are tight that month, paying even the minimum amount prevents it from being recorded as a "delay."
💳 Don't Max Out Your Card Limit
The credit utilization rate, how much of your limit you use, is important.
Let's say your credit card limit is 20,000 TL. If you spend 18,000-19,000 TL every month, the bank thinks: "This person is pushing their limit to the end, they are not financially comfortable." And this thought is reflected negatively on your score.
The general acceptance is this: use a maximum of 30% of your limit. So if you have a 20,000 TL limit, your monthly spending should not exceed 6,000 TL. But if you say "I spend more," the solution is simple: request a limit increase from your bank. Even if your spending remains the same, your utilization rate decreases when your limit increases.
🔍 Don't Constantly Apply for Credit
Every application creates an "inquiry" record.
Many people are not aware, but every time you apply for credit, the bank queries your Findeks report. These inquiries are recorded. If you apply for credit to 5-6 different banks in a short time, the system reads it like this: "This person is very desperate for money, they are knocking on every door."
Therefore, make a credit or credit card application when you really need it and after doing your research and choosing the most suitable bank. Instead of applying to five banks at the same time, compare interest rates and make a single application to the most suitable one.
Info: Querying your Findeks report yourself (looking at your own score) does not lower your score. Only inquiries made by banks and financial institutions affect it. So you can check it if you're curious, it won't be a problem.
🏛️ Don't Close Your Old Cards
The length of credit history builds trust.
Let's say you have a credit card you've been using for 8 years. You don't use it anymore and say "I'll close it." Stop! If you close that card, you also delete your 8-year credit history. From the system's perspective, it looks as if you've had a financial life for a shorter period.
Old accounts represent your reliability history. The longer you have a trouble-free credit history, the more banks trust you. Even if you don't use the card, keep it open; make a small purchase a few times a year so the bank doesn't close it itself due to inactivity.
Tip: If you have an old card with an annual fee, call the bank and ask for it to be converted to a free card. This way, the account stays open and it doesn't cost you anything.
📊 Use Different Types of Credit
Diversity is an indicator of financial maturity.
Just using a credit card is a start, but banks want to see that you can also successfully manage different types of credit. For example, you took out a personal loan and are paying your installments regularly — this reflects positively on your score.
But beware: don't take out unnecessary credit just to raise your score. If there is something you already need (car, house, education) and you can afford the installments, this diversity will occur naturally. The goal is to appear as "someone who can manage different financial responsibilities" in the eyes of the system.
Credit types: Credit card, personal consumer loan, housing loan, vehicle loan, tradesman loan... If you pay more than one of these regularly, the system gives you a higher score.
📉 Reduce Your Existing Debts
The debt/income ratio is an important indicator for banks.
If your monthly income is 15,000 TL but your total debt installments are 12,000 TL, banks find you risky. Because a large part of your income already goes to debt, there is a high probability that you will not be able to pay a new loan.
What you need to do is simple but requires discipline: close your highest interest debts first. Credit card debts usually have the highest interest, start with them. Then clear small debts. Every closed debt pulls your score up.
Tip: Try the "snowball method," close the smallest debt completely first, then move on to the next one. Every closed debt increases your motivation. Alternatively, apply the "avalanche method": start from the debt with the highest interest, it is mathematically more advantageous.
🔎 Check Your Findeks Report Regularly
Erroneous records might be unfairly lowering your score.
Sometimes there can be errors in the Findeks report. A debt you closed might still appear as "open," an installment you paid might be recorded as "delayed." Such errors lower your score for no reason.
You can get your free report once a year from findeks.com. Examine the report carefully. If you see an erroneous record, contact the relevant bank or financial institution and request a correction. If the bank does not make the correction, you can appeal directly to the KKB.
✓ Checklist - Look for these in the report:
- ✓ Do debts you closed still appear as "open"?
- ✓ Is there an installment written as "delayed" even though you paid on time?
- ✓ Is there a credit or card record you never applied for? (Could be fraud)
- ✓ Is there an inquiry record from an organization you don't recognize?
- ✓ Is your personal information (name, ID, address) correct?
⏳ Be Patient, the Process Takes Time
Credit score is a marathon, not a sprint.
Finally, the most important fact: raising your credit score doesn't happen overnight. When you start implementing the steps above, you can see the first positive changes within 2-3 months. But a serious, permanent improvement usually takes 6-12 months.
It's very easy to lower, it takes time to raise. But once you reach a good level, you stay there as long as you maintain the right habits. And believe me, life is much more comfortable with a high credit score: lower interest, higher limit, faster loan approval.
Increasing Credit Limit with Claude
🧮 Create a Personal Budget Plan
Tell Claude your monthly income and expenses, and it will create a detailed budget plan for you. It calculates which items you can save on, your debt payment priorities, and the amount you can save monthly.
Example prompt: "My monthly income is 25,000 TL, rent is 8,000 TL, groceries 4,000 TL, credit card debt 15,000 TL, personal loan installment 3,200 TL. Create a budget plan for me with debt payment priority."
📉 Determine a Debt Eradication Strategy
If you have more than one debt, Claude calculates which one is more suitable for you by applying the snowball and avalanche methods to your debts. When you enter the interest, maturity, and monthly installment of each debt, it offers you the roadmap where you will pay the fastest and least interest.
Example prompt: "I have 3 different debts: Bank A credit card 12,000 TL 4.5% monthly interest, Bank B personal loan 30,000 TL 18 months left monthly 2,100 TL, Bank C credit card 5,000 TL 3.8% interest. Compare the snowball and avalanche methods."
📋 Have Your Findeks Report Interpreted
If you have difficulty understanding the terms and records in the Findeks report, you can learn what they mean and the points you should pay attention to by explaining the information in the report to Claude. When you see an erroneous record, you can have an appeal letter written.
Example prompt: "In my Findeks report, a loan I closed in 2024 still appears as 'open'. Can you write an official appeal/correction request letter to send to the bank?"
🎯 Have Your Credit Card Utilization Rate Calculated
Give Claude the limits and monthly expenditures of all your credit cards, and it will calculate your total utilization rate and the individual rate of each card. It allows you to optimize how much you should spend from which card.

📊 Create a Monthly Tracking Table
Ask Claude to prepare a monthly debt tracking chart, payment schedule, and credit score progress table in Excel or table format. Regular tracking is the biggest supporter of discipline.
Example prompt: "Create a 12-month debt tracking table for me. Prepare an Excel showing how much I will pay to which debt each month, the remaining balance, and my total utilization rate."
