Banks and licensed lenders are two different worlds, even though the same KNF supervises both. A bank has higher requirements, a longer procedure, but a lower RRSO. A lender approves faster, accepts a less-than-perfect profile, but the RRSO climbs.

When a bank

You have a regular employment contract or you've been self-employed for over a year. Your BIK is clean or has minor positive entries. You need 10 000 PLN or more. You can wait two-three days for a decision. Under these conditions, a bank almost always comes out cheaper.

When a KNF-licensed lender

You need a small amount for a short period. The Vivigo offer checked on 8 October 2026 provides a first loan of 100–5,000 PLN for 61 days at 0% RRSO if repaid on time. Check the current terms and plan how to repay the whole amount before applying.

When neither

You don't know how you'll pay it back. You're taking out a loan to pay off an earlier loan („rolling"). Your monthly payments already eat more than 50% of your net income. Those are signs that the problem is not a missing loan — it's the structure of your spending or income, and a new loan will deepen it.

How to check a lender is legitimate

Look it up in the public KNF register at rpkip.knf.gov.pl. Every lender operating in Poland has to be listed there. If they aren't — don't borrow. On top of the register, the Polish anti-usury act of 18 December 2022 caps the non-interest costs that can be charged. Both rules apply at the same time.

Real 2026 cost gaps

The Vivigo offer checked on 8 October 2026 covers a first loan of 100–5,000 PLN for 61 days at 0% RRSO. Representative example: 1,100 PLN for 61 days, zero cost and 1,100 PLN to repay. The promotion applies to the first loan repaid on time. Repeat loans have different costs. A 36-month instalment loan is a different product; the monthly payment alone does not make the two comparable.

My advice: compare the total repayment and its due date. Zero cost will not help if you cannot repay the loan after 61 days.

How to choose between the two, step by step

Three questions: Do you need money today or in 3 days? What is your BIK score (check at bik.pl)? How much income surplus do you have after existing payments? A bank is the answer if you can wait, your score is 400+, and after existing payments at least 30% of income is left. A non-bank lender — if any of these conditions is not met.
