Mortgage Calculator Poland 2026: How Much Can You Borrow?

Quick Answer

With a net income of 7,000 PLN (~€1,600) and no existing debts, you can borrow approximately 350,000–420,000 PLN for a mortgage in Poland in 2026 (25–30 year term). The exact amount depends on your bank, WIBOR rate, DTI ratio, and down payment size.

Read on for the full calculator, comparison tables, and step-by-step guide.

How Polish Banks Calculate Your Borrowing Power

Polish mortgage affordability is determined by four key factors:

1. Net income — your take-home pay after tax and ZUS contributions
2. Debt-to-Income ratio (DTI) — maximum share of income that can go toward all loan payments
3. Interest rate — WIBOR (reference rate) + bank margin
4. Loan term — longer = higher borrowing capacity (but more interest paid)

The KNF Regulation (Polish Financial Supervision Authority)

KNF recommends maximum DTI limits:

In practice, most banks cap DTI at 40–50% regardless of income level.

Step-by-Step Mortgage Calculator

Step 1: Determine Your Qualifying Income

Banks accept different income sources with varying requirements:

For expats: Most Polish banks accept foreign income, but you'll need translated and apostilled documents. Some banks (mBank, ING) have dedicated expat mortgage programs.

Step 2: Subtract Existing Obligations

Banks count all monthly commitments:

• Existing loan installments
• Credit card limits (3–5% of limit counted as monthly obligation)
• Store "0% installments" — yes, these count!
• Leasing payments (if personal, not business)

Example: You earn 10,000 PLN net but have a 500 PLN car loan and a credit card with 15,000 PLN limit. Bank counts: 500 + 600 (4% of limit) = 1,100 PLN in obligations.

Step 3: Calculate Maximum Monthly Payment

Max payment = Net income × DTI − Existing obligations

For our example (DTI 50%):

10,000 × 50% − 1,100 = 3,900 PLN maximum monthly payment

Step 4: Convert Payment to Loan Amount

Current rates (Q1 2026):

At 8.0% interest over 25 years, here's what your maximum payment gets you:

Step 5: Factor in the Down Payment

Minimum down payment in Poland (2026): 20% of property value (or 10% with low-equity insurance).

With 10% down (+ insurance ~0.1% of loan/year):

• 400,000 PLN loan → apartment worth ~444,000 PLN

Borrowing Power by Income — Quick Reference Table

Assumptions: no existing debts, single applicant, DTI 50%, WIBOR 5.80% + 2.20% margin, 25-year term.

Couples combine incomes. A couple earning 7,000 + 6,000 PLN net (13,000 total) can borrow ~845,000 PLN.

What Reduces Your Borrowing Power?

1. Existing Debts & Credit Cards

Every unused credit card limit reduces capacity by 300–500 PLN/month. Close cards you don't use before applying.

2. Number of Dependents

Banks subtract living costs per household:

• Single: ~1,000–1,500 PLN
• Couple: ~1,800–2,200 PLN
• Couple + 1 child: ~2,500–3,000 PLN
• Couple + 2 children: ~3,200–3,800 PLN

3. Employment Type

B2B/self-employment requires 12–24 months of history. Fixed-term contracts need 6+ months remaining.

4. Credit History (BIK)

Late payments — even small ones (phone bills, store installments) — can reduce your BIK score and cut available credit by 10–20%.

5. Age

Banks require repayment before age 65–70. A 50-year-old gets a maximum 15–20 year term → lower borrowing capacity.

How to Maximize Your Mortgage Capacity

1. Close unused credit cards and limits — each one costs you ~30,000 PLN in borrowing power
2. Pay off small loans — even a 200 PLN/month payment reduces capacity by ~26,000 PLN
3. Extend the term — 30 years instead of 25 adds ~8–10% capacity
4. Add a co-borrower — partner or parent
5. Increase down payment — 30% down = better margin + higher scoring
6. Apply to 3+ banks — affordability varies by 15–20% between banks
7. Wait for WIBOR cuts — each 0.5 p.p. drop adds ~5% capacity

WIBOR Impact Simulation

How WIBOR changes affect borrowing power (8,000 PLN net income, DTI 50%, 25 years):

Every 1 percentage point of WIBOR = ~50,000–70,000 PLN less borrowing power at typical income levels.

Bank-by-Bank Comparison (Q1 2026)

Borrowing power differs by 15–20% across banks:

💡 Always apply to at least 3 banks — the differences can be surprising.

Hidden Costs Beyond the Mortgage Payment

Total additional costs on a 400,000 PLN loan for a 500,000 PLN property: approximately 15,000–25,000 PLN in the first year.
