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 420,000–500,000 PLN for a mortgage in Poland in 2026 (25–30 year term). Borrowing power rose during 2026 as the NBP cut rates: WIBOR 3M fell to ~3.84% and effective mortgage rates to ~6.0% (from ~8% a year earlier), which lifts capacity by roughly 15–18%. 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 (mid-2026, after the NBP cut to a 3.75% reference rate in March 2026):

At ~6.1% 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 3.84% + 2.20% margin (~6.1% total), 25-year term.

Couples combine incomes. A couple earning 7,000 + 6,000 PLN net (13,000 total) can borrow ~1,000,000 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. The 2025–early 2026 easing has already added roughly 100,000 PLN of capacity at this income level versus the peak.

Bank-by-Bank Comparison (mid-2026)

Borrowing power differs by 15–20% across banks (capacity shown at the current ~6.1% effective rate):

💡 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.

FAQ

How much can I borrow on 5,000 PLN net salary?

With no existing debts, single applicant — approximately 384,000 PLN over 25 years at the current ~6.1% effective rate (WIBOR 3M ~3.84%). That's up from ~325,000 PLN at the 2024–25 peak rate of ~8%.

Can foreigners get a mortgage in Poland?

Yes. EU citizens face no restrictions. Non-EU citizens may need a permit from the Ministry of Internal Affairs for certain property types.

Does B2B income count?

Yes, but banks require 12–24 months of business history and count income after costs and ZUS.

Is a fixed-rate mortgage better for affordability?

Usually no — fixed rates are higher (9–10%), reducing borrowing power. But they offer payment certainty.

Will WIBOR fall further?

Most of the easing has already happened: the NBP cut its reference rate to 3.75% in March 2026 and WIBOR 3M dropped to ~3.84%. The MPC's current guidance signals a pause, with the next cut unlikely before 2027 — so don't count on another big near-term boost to borrowing power.

Should I close credit cards before applying?

Yes — the effect is visible within 1–3 months after closing (BIK update).

Summary

Your mortgage borrowing power in Poland in 2026 depends mainly on income, existing debts, WIBOR, and loan term. At the median salary (~7,000 PLN net), expect to borrow 420,000–500,000 PLN at the current ~6.1% effective rate — meaningfully more than a year ago thanks to the NBP's 2025–early-2026 rate cuts.
