mBank vs. PKO BP — Which Polish Bank Is Better in 2026?

mBank and PKO BP represent two philosophies of Polish banking. mBank was born digital — one of Europe's earliest online-only banks, now with minimal physical presence. PKO BP is Poland's largest bank by assets, the state-controlled giant with over 900 branches and the legacy systems to match. Choosing between them depends on what you value most.

Quick Answer

There is no single winner — it depends on what you value. Choose mBank for the best digital experience: a top-rated app, a no-conditions free eKonto, and faster online onboarding for expats. Choose PKO BP for branch access (900+ branches), the largest ATM network, and mortgage support; its Konto za Zero is free with 1,000 PLN/month income. Many Poles simply use both.

Account Fees

mBank eKonto: Zero monthly fee with no conditions. Free PLN transfers (domestic), free card transactions, free ATM withdrawals at mBank ATMs and partner networks. Foreign ATM withdrawals: free up to 3 per month, then 5–9 PLN each.

PKO BP Konto za Zero: Zero monthly fee if you receive at least 1,000 PLN/month (salary, pension, or other regular income). Without the income condition: 8 PLN/month. Free domestic transfers. ATM withdrawals: free at PKO and BZ WBK ATMs (largest network in Poland — over 3,000 machines), 5 PLN at other ATMs.

Verdict: mBank wins on simplicity — no conditions for free banking. PKO BP's income requirement is easy to meet for most working adults, and their ATM network is larger.

Mobile and Online Banking

mBank app: Consistently ranked among the best banking apps in Poland and Europe. Clean interface, fast biometric login, instant transfers (Express Elixir), mobile payments (BLIK, Google Pay, Apple Pay), investment access, and spending categorization. The app feels like it was designed by people who actually use mobile banking.

PKO BP iPKO / IKO app: Significantly improved in recent years but still feels more complex. Full BLIK support (PKO invented BLIK), mobile payments, investment access. The interface has more layers and menus — reflecting the bank's broader product range but at the cost of simplicity.

Online banking (browser): mBank's web interface is modern and responsive. PKO BP's iPKO portal works but looks dated compared to neobank standards. Both support full functionality — transfers, standing orders, investment products, loan applications.

Verdict: mBank has the better app and online experience. PKO BP is adequate and improving but not best-in-class.

Savings and Deposit Rates

Savings rates in Poland fluctuate with NBP interest rate decisions. As of early 2026:

mBank: Standard savings account (eMax): approximately 3.0–4.0% for new funds (promotional rate for 3–4 months), then drops to 0.5–1.5%. Term deposits: 4.0–5.5% for 3–12 month terms.

PKO BP: Savings account: approximately 2.5–3.5% promotional for new funds. Term deposits: 4.0–5.0% for standard terms. PKO occasionally offers competitive rates on structured deposits but typically lags behind mBank and newer competitors.

Verdict: Rates are competitive and change frequently. Neither bank offers best-in-class savings rates — for pure savings optimization, smaller banks (Toyota Bank, Nest Bank, Credit Agricole) and neobanks often offer higher promotional rates. Both mBank and PKO are adequate if you want your savings alongside your primary account.

Credit and Loan Products

Mortgages: PKO BP is the largest mortgage lender in Poland. Their process is well-established, and branch access makes document submission easier. mBank offers competitive mortgage rates but the primarily online process can be frustrating for a product as complex as a mortgage.

Consumer loans: Both banks offer personal loans with rates of 8–15% APR depending on amount, term, and creditworthiness. mBank's fully online application process is faster (decision in minutes for existing customers). PKO BP may require a branch visit for larger amounts.

Credit cards: Both offer standard and premium cards. mBank's cashback options are slightly more competitive. PKO BP's premium cards come with lounge access and travel insurance that appeal to frequent travelers.

Verdict: PKO BP for mortgages (experience and branch support). mBank for quick consumer credit (speed and convenience).

Investment Products

mBank: Access to stocks (GPW and foreign), ETFs, bonds, mutual funds, and IKE/IKZE accounts through eMakler (their brokerage platform). Pricing is competitive — 0.29% commission on GPW trades, access to several foreign exchanges.

PKO BP: PKO BP Biuro Maklerskie is one of the largest brokers in Poland. GPW access, foreign markets, bonds, IPO participation, and IKE/IKZE. The full-service brokerage is more suited to traditional investors who may want phone or branch-based advisory services.

Verdict: mBank for self-directed digital investors. PKO BP for those who want advisory support or prefer a full-service brokerage.

Customer Service

mBank: Primarily phone and chat. No branches (effectively). Response times for chat: typically 5–15 minutes. Phone support: adequate but can involve long hold times during peak periods. The trade-off of being a digital bank — when you need human help, it is less accessible.

PKO BP: Over 900 branches nationwide — you can walk in and talk to someone. Phone and chat support available. Branch access is the decisive advantage for complex issues: mortgage modifications, estate matters, account disputes, and anything requiring document signing.

Verdict: PKO BP wins decisively for anyone who values in-person service. mBank is fine for routine needs.

For Expats and English Speakers

mBank: Full English interface available (app and web). Account opening possible online with a Polish PESEL. English-language customer support: limited but available.

PKO BP: English interface available. Account opening may require a branch visit. Some branches in major cities (Warsaw, Krakow, Wroclaw) have English-speaking staff. Documentation in English: available for basic products.

Verdict: mBank is slightly easier for English speakers due to the fully digital process.

Integration with Financial Tools

Both banks support CSV statement exports compatible with budgeting apps. Freenance supports imports from both mBank and PKO BP, allowing you to aggregate accounts and track spending automatically.

Who Should Choose Which?

Choose mBank if: You want a modern digital banking experience, prefer managing everything on your phone, do not need branch access, and value a clean and fast interface.

Choose PKO BP if: You want branch access, are applying for a mortgage, prefer a traditional banking relationship, or live outside major cities where mBank's digital-only approach may feel limiting.

Use both: Many Poles maintain a PKO BP account for the branch network and ATM access alongside an mBank account for daily digital banking. There is no rule against having accounts at both banks.
