Building credit as a student feels like one of those “adult things” you’re supposed to figure out eventually, until you realise it’s already shaping your financial future.
Even in 2025, students are still making the same five avoidable mistakes that quietly hold their credit scores back.

Here’s what’s really going wrong — and how to fix it before it costs you an apartment, a loan, or even a job. 

1. Thinking You Need a Credit Card to Build Credit

Most students still believe credit cards are the only way to start building credit. But here’s the truth: traditional credit cards are not beginner-friendly.
They often require a credit history to apply, come with interest rates over 25%, and make it easy to fall into debt before you even realise it.

What actually works:
Modern debit-linked credit builders like Fizz flip the model. Fizz works on debit rails but functions like a credit card — giving you a line of credit that’s automatically repaid daily from your linked bank account. You spend only what you have, avoid interest, and still report to Experian and TransUnion to build real credit history.

No credit check. No interest. No debt traps.
It’s the easiest way to build credit safely as a student.

2. Paying Late (Even Once)

Late payments are one of the biggest score killers, and even one missed due date can stay on your credit report for up to seven years.
For students juggling classes, rent, and internships, missing a due date usually isn’t about carelessness; it’s about chaos.

Fix it:

• Automate payments. Set every bill to autopay — even the small ones.
  
  

• Use daily autopay tools. Fizz’s daily Autopay clears your balance automatically every day, so you literally can’t forget to pay on time.
  
  

• Track your due dates in one place. Apps like Mint or Notion templates for bills can help.

Pro tip: Payment history makes up 35% of your credit score, so even tiny charges paid consistently matter more than big payments made late.

3. Ignoring Credit Utilization

Credit utilization (how much of your available credit you use) makes up another 30% of your credit score.
The rule of thumb: try to keep it below 30% — but most students don’t even know what that means.

Example:
If you have a $1,000 limit and spend $600, that’s 60% utilisation — and your score will likely drop.

Fix it:

• Make multiple smaller payments each month instead of one big one.
  
  

• Keep your spending modest relative to your limit.
  
  

• Or, better yet, use a debit-linked builder like Fizz that repays daily — your utilization resets every 24 hours, keeping it naturally low.
  
  

4. Not Starting Early Enough

Many students think credit is something to worry about after graduation.
But starting early gives your score more time to mature — and “length of credit history” makes up 15% of your FICO score.

If you start building credit in your freshman year, you’re already years ahead when you graduate.

Fix it:

• Open a credit-building account as soon as you have a checking account.
  
  

• Use it regularly for small, manageable purchases (like coffee or textbooks).
  
  

• Always repay in full and on time.

Fizz makes this frictionless. You can use the Fizz card daily for small expenses, and it reports your responsible behaviour automatically — no loans, no deposits, no waiting until you’re “ready.”

5. Overlooking How Credit Is Reported

Here’s one mistake even smart students make: not all tools report to all three credit bureaus.
Some “credit builders” only report to one, meaning your hard work doesn’t fully show up when lenders check your profile.

Fix it:
Use platforms that report to at least two major bureaus.
Fizz reports to Experian and TransUnion, giving your credit score a broader foundation across the systems most lenders use.

Other common missteps:

• Using BNPL (“Buy Now, Pay Later”) services, thinking they help credit (they usually don’t).
  
  

• Cancelling your oldest account too early — which shortens your credit history.
  
  

• Not checking your credit report for errors — 1 in 5 reports has at least one mistake.
