PLN 20,000 Savings - Fixed Deposit or Savings Account?
Twenty thousand złoty is one of the most common savings amounts among Polish savers - large enough to be worth shopping around for the best rate, yet still comfortably within the deposit limits of nearly every promotional offer on the market. I checked BankSorter's live data as of September 22, 2026 for both fixed deposits and savings accounts to answer one concrete question: where does PLN 20,000 earn the most?
Best Fixed Deposits for PLN 20,000 - September 2026
Good news first: none of the fixed deposits in our database have an amount cap that would exclude PLN 20,000 - every offer's minimum-maximum range comfortably covers it, so they can all be compared head to head.
Highest-rate deposits
- Nest Bank - Nest Lokata Witaj: 6.1% for 6 months (PLN 1,000–25,000)
- VeloBank - VeloLokata dla Aktywnych: 6.0% for 6 months (PLN 1,000–50,000)
- Crédit Agricole - Lokata Powitalna: 5.5%, but only for 1 month (PLN 1,000–100,000)
- Inbank - Lokata na Start: 4.5% for 6 months (PLN 1,000–50,000)
- Erste Bank Polska - Lokata na Powitanie: 4.5% for 3 months (PLN 1,000–50,000)
Nest Bank offers the nominally highest rate at 6.1%, closely followed by VeloBank at 6.0%. On PLN 20,000 deposited for 6 months, the difference between the two comes to a symbolic PLN 10 gross, so in practice both can be treated as joint leaders.
How much you would actually earn on PLN 20,000
I calculated the estimated gross return (amount × rate × months/12) for three comparable 6-month offers:
- Nest Bank (6.1%, 6 months): approx. PLN 610 gross
- VeloBank VeloLokata dla Aktywnych (6.0%, 6 months): approx. PLN 600 gross
- Inbank Lokata na Start (4.5%, 6 months): approx. PLN 450 gross
These are rough estimates - I am not assuming any specific interest-capitalisation method, since not every offer's terms specify one in the data available to me, and the 19% Belka tax still needs to be deducted from the gross figure. After tax, the Nest Bank deposit leaves roughly PLN 494 in your pocket, not PLN 610.
Watch out for one trap: Crédit Agricole advertises an attractive 5.5% rate, but its term is just 1 month - on PLN 20,000 that works out to only around PLN 92 gross, far less than the 6-month deposits despite the higher headline rate. A high percentage means little without checking the period it actually applies to.

Savings Accounts - the Fully Liquid Alternative
Before locking PLN 20,000 into a fixed deposit, it is worth checking savings accounts - because here there is an interesting finding. Every promotional savings account in our database sets its full-rate threshold at PLN 100,000 or higher (the lowest threshold, PLN 100,000, belongs to Bank Pekao and Crédit Agricole). That means the entire PLN 20,000 qualifies for the top promotional rate on every one of these accounts - you do not need to worry about part of your savings falling below the threshold and earning a lower rate.
Best savings accounts for PLN 20,000
- Bank Pekao - Konto oszczędnościowe: 5.7% (PLN 100,000 threshold), 92-day promotion, new/inactive clients only, requires min. 5 card/BLIK transactions per month
- Crédit Agricole - Rachunek Oszczędzam Plus: 5.5% (PLN 100,000 threshold), 100-day promotion, only for new clients opening a full account+card+marketing-consent package
- Bank Millennium - Konto Oszczędnościowe Profit: 5.25% (PLN 200,000 threshold), 91-day promotion, new funds only, min. 5 transactions per month
For PLN 20,000 deposited for the full promotional period, the estimated gross return looks like this: Bank Pekao approx. PLN 287 (92 days), Crédit Agricole approx. PLN 301 (100 days), Millennium approx. PLN 262 (91 days). That is less in absolute terms than the best 6-month deposits, but keep in mind the promotional period on savings accounts is shorter, and the rate typically drops once it ends.
Mind the conditions: several of these offers (Pekao, Crédit Agricole, UniCredit) are reserved strictly for new clients or require opening an additional personal account - this is not a "deposit and forget" option for everyone. Always check the specific promotion's terms before opening an account. The full list with conditions and a net-return calculator is available in our savings accounts overview, while the shorter best savings accounts ranking shows the leaders in one place.
Fixed Deposit or Savings Account - Which to Choose for PLN 20,000?
The choice mainly comes down to one question: can you afford to lock the money away for several months?
- A fixed deposit usually offers a higher rate but locks your funds for the full contract term. Breaking a deposit early usually means losing the interest owed - check this in the terms before depositing.
- A savings account lets you withdraw money at any time without losing already-accrued interest, giving you a safety net for unexpected expenses - at the cost of a somewhat lower, typically shorter promotional rate.
If you are certain you will not need the PLN 20,000 for the next 6 months, a deposit at Nest Bank or VeloBank will earn you more. If you would rather keep access to your cash "just in case," a savings account at Bank Pekao or Crédit Agricole is a reasonable compromise - lower return, but full liquidity.
Summary - What You Should Do
For PLN 20,000 in September 2026, the highest real deposit rates come from Nest Bank (6.1%, 6 months) and VeloBank (6.0%, 6 months) - both within their offers' limits. Among savings accounts, PLN 20,000 always qualifies for the full promotional rate, since the lowest threshold on the market is PLN 100,000 - Bank Pekao leads here at 5.7%. Before deciding, compare current deposits and savings accounts on BankSorter, check the exact terms of your chosen promotion, and remember to factor in the Belka tax when calculating your real return.
