Bank Deposit Calculator 2026

Calculation Result

After 18 months of saving 25,000 zł at an interest rate of 5.2% compounded monthly, your total savings will grow to approximately 27,301.50 zł. When considering an inflation rate of 3.8%, the real value of your savings will be around 26,244.36 zł.

This means that while your nominal savings increase, inflation will slightly decrease the purchasing power of your money. It's important to consider both aspects when planning your savings strategy.

How the Calculator Works

The Bank Deposit Calculator uses the formula for compound interest to estimate how much your investment will grow over a specified period. You input the initial amount, the interest rate, and the length of time you plan to save. The calculator then computes the total amount you will have at the end of the period, accounting for monthly compounding and inflation effects.

Example Calculation

Let's say you deposit 30,000 zł at an interest rate of 4.5% for 24 months. The calculation steps would be:

1. Calculate the monthly interest rate: 4.5% / 12 = 0.375%
2. Apply the compound interest formula: A = P(1 + r/n)^(nt)
3. After 2 years, your total amount would be approximately 32,695.50 zł.

Additional Tips

Consider setting aside a portion of your savings for emergencies, and review your investment strategy regularly. Compare different savings accounts to find the best interest rates and terms, as even a small difference can significantly impact your final amount.
