I uncovered the hidden debt-to-income ratio impact of Buy Now, Pay Later accounts. Here is how I account for BNPL and why lenders now care.

I learned about the hidden debt-to-income ratio: accounting for “Buy Now, Pay Later” the hard way. I was applying for a home loan, and I thought I had done everything right. I had a good deposit, a steady income, and I had paid down my credit cards. But the lender came back with a question I did not expect. They asked for a list of all my Buy Now, Pay Later accounts. I had a few.
A dress from Afterpay. Some sneakers from Zip. A small appliance from a retailer. I thought these were harmless. I paid them off on time. But the lender saw them differently. They added up every outstanding balance and every monthly payment, and my debt-to-income ratio shot up. I almost lost the loan over a few small purchases.
That experience taught me the importance of the hidden debt-to-income ratio: accounting for “Buy Now, Pay Later” . These accounts look like convenience, but they are debt. And lenders now treat them seriously. In this post, I will share what I learned, how BNPL affects your borrowing power, and how to calculate your true DTI including these hidden debts.
Why BNPL Is Now Considered Debt: Accounting for “Buy Now, Pay Later”
For years, Buy Now, Pay Later services operated in a grey area. They were not regulated like credit cards or personal loans. They did not appear on credit reports. Many people, including me, thought they were just a payment method, not a loan. But that changed in June 2025 .
In Australia, new regulations came into effect requiring BNPL providers to comply with responsible lending obligations . This means they must now conduct credit checks and assess whether you can afford the repayments . These checks appear on your credit report as enquiries . More importantly, lenders now consider BNPL accounts when assessing home loan applications .
This is the core of the hidden debt-to-income ratio: accounting for “Buy Now, Pay Later” . Even if you pay on time, the accounts exist. They represent a financial commitment. Lenders must include them in your DTI calculation .
How Lenders Calculate BNPL in DTI
When I asked my mortgage broker how BNPL affected my application, he explained the math. Lenders look at BNPL in two ways.
First, they look at the outstanding balance. If you have a balance on Afterpay or Zip, that is debt. It reduces your borrowing power just like a credit card balance .
Second, they look at the monthly repayments. Even if you pay off each purchase quickly, the regular payments reduce your disposable income . Lenders calculate these payments as an ongoing expense. For example, if you have four BNPL plans each requiring $50 a month, that is $200 a month less available for a mortgage.
This is the hidden debt-to-income ratio: accounting for “Buy Now, Pay Later” in action. These small amounts add up. They can push your DTI over the lender’s limit.
The Data on BNPL Usage: Accounting for “Buy Now, Pay Later”
I was shocked when I saw the statistics about BNPL usage in Australia. According to research, almost 1 in 4 Americans have used BNPL, and similar trends exist in Australia . More importantly, 60% of BNPL users have multiple simultaneous loans . This is called “debt stacking,” and it is a red flag for lenders.
The data also shows that BNPL is increasingly used for everyday expenses like groceries and household items, not just for big purchases . This means the debt can be ongoing and harder to track.
But here is the surprising part. Despite the negative perception, the average credit score of an Afterpay customer is 743, which is considered very good . Gen Z Afterpay users actually have higher average scores than their peers applying for credit cards . This suggests that many BNPL users are responsible borrowers. However, lenders still need to account for the debt when assessing a mortgage .
This makes the hidden debt-to-income ratio: accounting for “Buy Now, Pay Later” a challenge. Responsible users get penalized even though they manage their payments well.
The Credit Reporting Changes: Accounting for “Buy Now, Pay Later”
Another factor I had to understand was how BNPL now appears on credit reports. Under Comprehensive Credit Reporting (CCR), BNPL providers can now share both positive and negative repayment information with credit bureaus .
If your BNPL provider participates in CCR and you make on-time payments, this can actually help your credit score . It shows you are reliable. However, if you miss payments, those defaults will appear and hurt your score .
But even if your provider does not report to credit bureaus, lenders can still see BNPL activity on your bank statements . When you apply for a home loan, you must provide several months of bank statements. Lenders scan these for regular payments to BNPL services . This is another way the hidden debt-to-income ratio: accounting for “Buy Now, Pay Later” becomes visible.
How I Calculate My True DTI Including BNPL
After my near-miss with the home loan, I created a system to ensure I never underestimate my debt again. Here is how I calculate my true DTI including BNPL.
First, I list all my traditional debts. Mortgage or rent, car loan, student loans, credit card minimum payments.
Second, I open every BNPL app on my phone. Afterpay, Zip, Klarna, Paypal Pay in 4. I check each one for outstanding balances. I also check for open but unused accounts. Even if I am not using them, the available credit can be considered a liability .
Third, I calculate the total monthly payments for all active BNPL plans. I add this to my monthly debt total.
Fourth, I divide by my gross monthly income : Accounting for “Buy Now, Pay Later”
This simple process gives me the hidden debt-to-income ratio: accounting for “Buy Now, Pay Later” . It is always higher than my traditional DTI. But it is the real number. It is what lenders will see.
A Real Example from My Life
Let me share a real example from when I did this calculation last year.
My traditional debts:
- Rent: $1,400
- Car payment: $320
- Student loans: $180
- Credit card minimum: $60
Total traditional: $1,960
My BNPL accounts (at the time):
- Afterpay: $120 balance, $40/month payments
- Zip: $80 balance, $30/month payments
- PayPal Pay in 4: $60 balance, $20/month payments
Total BNPL monthly: $90
New total monthly debt: $2,050
Gross monthly income: $5,200
True DTI: 39.4%
Without BNPL, my DTI was 37.7%. With BNPL, it was 39.4%. That 1.7% difference might not seem huge, but for a lender, it matters. It pushed me closer to the 43% limit. If I had more BNPL plans, I could have crossed the threshold.
This is the reality of the hidden debt-to-income ratio: accounting for “Buy Now, Pay Later” .
The Impact on Mortgage Applications: Accounting for “Buy Now, Pay Later”
Mortgage brokers and lenders now specifically ask about BNPL. According to one broker, using credit services too much or having too high limits can be a red flag for lenders as it indicates financial instability and living beyond one’s means . This includes BNPL.
Some borrowers are even told to close their BNPL accounts before applying for a mortgage . However, closing a well-managed BNPL account with a strong repayment history can actually remove valuable evidence of financial responsibility from your credit picture . There is no rule that requires closing BNPL accounts before applying for a home loan .
What matters most is how you manage your credit overall . But lenders will include active BNPL loans in your DTI calculation . This means the hidden debt-to-income ratio: accounting for “Buy Now, Pay Later” is now standard practice.
New Rules for 2026: Accounting for “Buy Now, Pay Later”
As of 2026, the rules have become even clearer. BNPL is now fully integrated into the credit system. The regulatory changes that began in June 2025 are now standard across the industry .
This means that every BNPL application results in a credit enquiry . Multiple enquiries in a short time can negatively impact your credit score . It can also cause lenders to perceive you as a greater lending risk .
For anyone planning to apply for a mortgage in 2026, understanding the hidden debt-to-income ratio: accounting for “Buy Now, Pay Later” is essential. You cannot afford to ignore these accounts.
What About HECS Debt?: Accounting for “Buy Now, Pay Later”
While researching DTI, I also learned about recent changes to HECS debt treatment. From September 2025, HECS/HELP debts are excluded from DTI calculations for lending purposes . This is great news for borrowers with student debt. However, HECS repayments still reduce your take-home income, so they affect serviceability .
But BNPL is treated differently. Unlike HECS, BNPL is still counted in full. This makes the hidden debt-to-income ratio: accounting for “Buy Now, Pay Later” even more critical. It is one of the few debts that borrowers often forget to include.
Tips for Managing BNPL Before a Home Loan
Based on my experience and the research, here are my tips for managing BNPL if you plan to apply for a mortgage.
First, reduce the number of active BNPL accounts . Fewer accounts signal stronger control over your finances. Aim to have no more than one or two at a time.
Second, always pay on time . Late or missed payments can negatively impact your credit score and will appear on your credit report . Set up reminders or automatic payments.
Third, avoid opening new BNPL accounts in the six months before applying for a home loan . Each application creates a credit enquiry, which can lower your score.
Fourth, check your credit report regularly . Make sure all your BNPL accounts are accurately reported. If you see errors, dispute them.
Fifth, be transparent with your mortgage broker. Tell them about all your BNPL accounts upfront. They can help you calculate the hidden debt-to-income ratio: accounting for “Buy Now, Pay Later” and advise on the best strategy.
The Bottom Line on BNPL and DTI
Buy Now, Pay Later is convenient, but it is not free money. It is debt. And in 2026, it is debt that lenders will find.
I learned this lesson through almost losing a home loan. Now I track every BNPL account like I track my credit cards. I know my true DTI, including every small payment. It has saved me from surprises and helped me stay in control.
If you are using BNPL, do not assume it is invisible. Assume lenders will see it. Assume it will affect your borrowing power. Calculate your true DTI today.
