How to Build Credit Score Using Your UnionBank Credit Card

Your UnionBank Credit Card isn’t just for spending — it’s your key to building a strong credit score in the Philippines.

For many Filipinos, especially first-time credit card holders, the term “credit score” might sound intimidating or something only banks care about. But here’s the truth: your credit score affects your financial future — from getting approved for a car loan, housing loan, or even another credit card with better rewards and higher limits.

If you just got your UnionBank credit card (congrats!), this guide will teach you how to use it smartly to build and maintain a great credit score — step by step.

🏦 What Is a Credit Score and Why Does It Matter?

Your credit score is a number that shows how responsible you are with credit. In the Philippines, credit bureaus like CIBI and TransUnion track your borrowing behavior and give lenders a score that represents your trustworthiness as a borrower.

A high credit score means:

You pay your bills on time.
You use your credit wisely (not too much, not too little).
You’ve built trust with financial institutions.

If you ever plan to apply for a car loan, housing loan, or another credit card, this score can make or break your application.

💳 How a UnionBank Credit Card Helps You Build Credit

Your UnionBank Credit Card is reported to credit bureaus each month. That means every swipe, payment, and late fee (if any) can affect your score.

Here’s how it helps you:

Builds your payment history — the biggest factor in your credit score.
Shows responsible usage — how much of your credit limit you use.
Establishes credit age — the longer you use it wisely, the stronger your credit record becomes.

Pro Tip: Think of your credit card as a tool for showing responsibility — not for spending money you don’t have.

⚙️ How to Use Your UnionBank Credit Card to Build Credit (Step-by-Step)

1. Use Your Credit Card Regularly — But Wisely

Use your card for daily purchases like groceries, utilities, or fuel. Regular usage helps build your history.
However, don’t max out your credit limit. Try to use only 30% or less of your available credit.

Example: If your limit is ₱20,000, keep your monthly spending below ₱6,000.

This shows UnionBank (and the credit bureau) that you can handle credit responsibly.

2. Always Pay on Time

Nothing damages your credit score faster than missed or late payments. Even one late payment can stay on your record for years.

✅ Set up reminders on your phone.
✅ Enable auto-debit from your UnionBank account if possible.
✅ Always aim to pay on or before the due date.

💡 Tip: Your due date is usually around 20 days after your statement date. Check your billing cycle carefully so you don’t miss it.

3. Pay the Full Amount (or As Much as You Can)

Paying only the minimum amount due keeps your account active, but it also means you’ll carry interest.
Carrying a balance month after month can hurt your credit score and make you pay more than you borrowed.

To see how much interest affects your payments, try the
👉 Credit Card Cost Calculator.
This free tool helps you estimate how much you’ll pay in interest if you don’t pay in full.

Example: If you owe ₱10,000 and only pay the minimum ₱500, you could end up paying thousands more over time.

4. Keep Your Credit Utilization Low

This is one of the most overlooked factors.
Credit utilization = (Amount you owe ÷ Credit limit) × 100%

If you keep this number below 30%, it tells lenders that you’re not over-reliant on credit.

Example:
If your limit is ₱30,000, and you spend ₱9,000, your utilization is 30% — perfect!

UnionBank and credit bureaus love to see low utilization because it signals you’re in control of your spending.

5. Don’t Apply for Too Many Cards at Once

Each time you apply for a new credit card or loan, banks do a “hard inquiry” on your credit report. Too many inquiries in a short time can lower your score.

Start with one — like your UnionBank card — and use it responsibly for at least 6 to 12 months before considering another.

6. Review Your Billing Statements Carefully

Your UnionBank eStatement or paper statement includes:

Statement date
Due date
Minimum and total amounts due
List of your transactions

Always review it monthly to check for:

Billing errors
Unauthorized charges
Late posting of payments

By catching issues early, you protect both your money and your credit reputation.

7. Don’t Close Your First Credit Card

Even if you’ve paid off your balance, keeping your first card active helps your credit age.
Older accounts show long-term reliability — an important factor in maintaining a high score.

If you’re not using it much, charge a small recurring bill (like your Netflix subscription or postpaid plan) to keep it active.

💡 Example Scenario: From Beginner to Excellent Credit

Let’s say Maria just got her UnionBank Classic Credit Card with a ₱20,000 limit.

She uses it monthly for groceries and bills — around ₱6,000 per month (30% utilization).
Every month, she pays the full balance before the due date.
After 12 months, Maria’s credit score improves significantly.

Later, she applies for a UnionBank Rewards Plus Card and easily gets approved with a higher credit limit — thanks to her good credit history.

📊 Why Good Credit Score Matters in the Philippines

A strong credit score gives you:
