Use a free monthly savings calculator to see how much to save monthly for 10k, 30k or 50k PLN and why interest and loan costs matter.

The UOKiK launched a free monthly savings calculator that shows how much you must save each month to hit a financial target. Consequently, it turns vague intentions into clear monthly numbers.

How the monthly savings calculator works

The tool lets you pick a goal and a time horizon. Moreover, it then computes the exact monthly contribution. For example, without interest you divide the goal by months. To reach 10,000 PLN you save 833 PLN per month for one year. Alternatively, you save 278 PLN for three years or 167 PLN for five years. For 30,000 PLN the same horizons need 2,500 PLN, 833 PLN and 500 PLN respectively. For 50,000 PLN you need 4,167 PLN for one year, 1,389 PLN for three years and 833 PLN for five years.

Interest matters, especially over time

An interest-bearing account reduces monthly needs. However, the effect grows with time. At 4% yearly interest you need about 818 PLN to reach 10,000 PLN in one year. Furthermore, saving for five years toward 50,000 PLN cuts the monthly payment from 833 PLN to about 754 PLN. Therefore, compound interest saves money across many payments. UOKiK gives a clear example. Buying a 10,000 PLN trip on credit costs 12,133 PLN in total. Instead, saving in advance and adding interest can reduce the real cost to about 9,782 PLN. Consequently, you avoid loan fees and interest that often exceed bank earnings.

What rates to expect in Poland

Actual bank rates vary a lot. In August 2026 standard savings offers range from about 1.4% to 4% typically. In contrast, welcome promotions can reach 6–7% for a short initial period. However, banks usually apply the high rate only for the first three or four months. In addition, promotions often limit the amount that earns the higher rate. Therefore, plan long-term saving on a conservative, non-promotional rate.

Using the UOKiK tool and related calculators

The UOKiK calculator lets you add irregular top-ups. Also, it produces a downloadable PDF plan you can save or share. Moreover, the same website offers a tool for early loan repayment calculations. It also includes a calculator to model loan payments under different interest rates. All three tools remain free and require no account creation.

💡 GOOD TO KNOW: If you are an expat, know that Poland applies a 19% tax on bank interest (the so-called “Belka” tax). Also, banks may ask for a PESEL (national ID number) or proof of residency for full account functions. ZUS means social security and NFZ means the public health insurer, so budget for social contributions if you work here. In addition, many promotion rates end early, so check standard rates. Finally, avoid impulse purchases on credit; saving first usually saves you money.
