Best savings accounts and deposits in Poland — October 2026 ranking

Data checked 1 October 2026

This month’s comparison looks at savings accounts and short-term deposits available in Poland, ranked by a published scoring system that weighs interest rates, balance limits and how clearly the rate conditions are stated.

Most of the products listed offer a promotional rate that applies only for a set period, after which a lower standard rate usually takes over. Where a provider does not publish a standard rate or guarantee details, this tends to pull its score down rather than suggesting any hidden problem.

Readers should check each provider’s current terms before opening an account, since promotional periods and balance limits can change.

Questions

What is the difference between a promotional and a standard interest rate?

A promotional rate applies for a limited period stated in the provider’s terms, after which the account typically reverts to a lower standard rate. Readers should check each provider’s terms for the exact switch-over point.

How long do the promotional rates in this comparison last?

The length varies by provider; some use a fixed number of days such as the periods noted for Credit Agricole, Pekao and mBank, while others such as BNP Paribas apply the rate only during a specific part of the deposit term. The provider’s terms should be checked for exact dates.

Are savings held in these accounts protected?

Only one entry in this comparison explicitly states a guarantee scheme. For the others, the comparison does not include this detail, so readers should check the relevant provider’s terms directly.
