Differences in creditworthiness results between banks are normal. Each bank has its own risk policy, safety buffers and approach to income sources. That is why you should compare — not rely on a single result.

If you need the basics, see: Creditworthiness — how banks assess it.

Why results differ

Common reasons include:

  • different treatment of income (self‑employment, civil contracts),
  • different living‑cost assumptions,
  • different rate‑stress buffers,
  • different treatment of card limits and overdrafts,
  • different requirements for down payment.

Additional criteria that may differ

Banks can also assess age, job tenure, industry or employment stability differently. Some differences stem from internal risk policies that are not visible in simple calculators.

How to compare banks properly

For a fair comparison:

  • use one consistent data set (income, costs, liabilities),
  • compare the same term and rate assumptions,
  • include APR (RRSO) and total cost,
  • check if extra collateral is required.

Use the Loan calculator and APR guide for orientation.

Use one consistent data set

For comparisons, keep one coherent set of inputs: net income, fixed living costs, card limits and existing instalments. Changing inputs between banks makes the comparison meaningless.

Make preliminary comparisons without submitting formal applications — use calculators and informational talks instead. This helps avoid a large number of credit inquiries.

Mortgage vs cash‑loan capacity

Differences are usually larger for mortgages due to collateral and down payment. For cash loans, see: Cash‑loan creditworthiness.

Down payment and LTV in practice

For mortgages, the down payment often changes not only pricing but also availability. Banks treat LTV thresholds differently, which affects capacity and the final offer.

Joint applications

Some banks treat co‑borrowers more favorably than others. Check how joint income and liabilities are assessed before applying.

How to prepare for bank discussions

  • calculate capacity in several variants,
  • clean up limits and liabilities,
  • prepare a complete document set,
  • review your BIK history,
  • select 2–3 banks for comparison.

Documents worth preparing

In practice, the process is faster when you have up‑to‑date income confirmations, account statements, a list of liabilities and data about the loan purpose. The more organised the set, the fewer manual adjustments are needed.

Practical scenarios

Scenario 1: two applicants with stable income. One bank shows higher capacity because it uses lower living‑cost assumptions.

Scenario 2: self‑employment income. Bank A applies a conservative coefficient; bank B is more flexible — hence different results.

Interpreting results vs final decision

Calculator results or initial conversations are only indicative. Final decisions depend on full document verification, risk policy and loan parameters. Treat early simulations as a starting point, not a guarantee.

Instalment vs total cost

A lower instalment does not always mean a better offer. A longer term can raise the total cost, so always compare APR (RRSO) and the total amount to repay. This often explains why banks assess “affordability” differently for the same amount. Remember that capacity is not fixed — it changes with income, living costs and market conditions. Refresh your simulations before applying.

Common mistakes

  • comparing banks with different assumptions,
  • submitting many applications at once,
  • ignoring total cost,
  • no safety buffer.

Frequently asked questions (FAQ)

Czy banki liczą zdolność według tych samych zasad?+
Nie. Różnią się polityką ryzyka, buforami i podejściem do dochodu.
Dlaczego w jednym banku mam wyższą zdolność?+
Bank mógł inaczej potraktować dochód, koszty lub okres kredytu.
Czy warto składać wnioski do wielu banków?+
Lepiej porównać oferty i składać wnioski rozsądnie, aby nie generować wielu zapytań naraz.
