Ola opened a savings account because the bank’s ad screamed “7% annually”. A month later she checked her interest history and the number didn’t match her math at all. The reason: that 7% only applied to the first 15,000 PLN, only for two months, and only to newly deposited funds. The rest of her savings — 60,000 PLN — sat at a rate the bank preferred not to mention in the banner.

That’s not an exception, it’s the norm in the savings-account market. This guide compares actual offers available in July 2026 — not catchy headlines, but effective interest rates once you factor in caps, promo periods, and conditions. If you’re still deciding between a savings account and a fixed-term deposit, start with Savings Account vs Fixed-Term Deposit: Which to Choose? — here we focus on picking a specific account.

How to Read a Ranking Without Getting Fooled

Before the numbers, four fine-print details that decide what you actually earn:

The cap on the amount covered by the high rate — above it, the rate drops, often to 1–2%.
The promo period — 2, 3, or 6 months. After that it reverts to the “standard” rate.
The “new money” condition — the high rate usually applies only to funds deposited after opening the account, not your existing balance.
Activity requirements — e.g. “10 card/BLIK transactions per month” or “salary deposit of at least 2,000 PLN”. Miss it, and you lose the promo.

An account with none of these conditions is rare — and usually means a lower, but more reliable, rate.

Savings Account Ranking — July 2026

As of July 2026, based on roundups from Bankier.pl and Subiektywnie o Finansach. Promotional offers change monthly — treat this as a starting point, not a final decision, and always check the current rate table on the bank’s own site before opening an account.

Bank & product	Rate	Cap	Period	Conditions
BOŚ Bank — Cyfrowy Zysk	7.00% (2% above the cap)	15,000 PLN	until 31.08.2026	New bank customers only
Nest Bank — Savings Account	6.10%	25,000 PLN	90 days	New customers + min. 2,000 PLN inflow and 10 card/BLIK transactions, or salary deposit
Trade Republic — Savings Account	6.00%	no cap	ongoing	No extra conditions, daily accrual
VeloBank — Elastic Account	6.00%	50,000 PLN	3 months	New online customers + min. 5 card/BLIK transactions/month + marketing consent
Bank Pekao — Savings Account	5.70%	100,000 PLN	3 months	Min. 5 card/BLIK transactions per month
Millennium / ING Bank Śląski	5.50%	200,000–400,000 PLN	variable	Various current-account activity requirements

For context: the average standard rate on the market (outside promotions) is around 3.71%, while the average promotional rate is around 4.47%. The NBP reference rate stands at 3.75% in July 2026 and has been stable since March — a useful benchmark: any offer clearly above that level is a promotion, not a lasting state of affairs.

Which Account Fits Your Situation

You have up to 15,000 PLN and don’t mind switching banks: BOŚ Bank offers the highest nominal rate (7%), but only for new customers and only until the end of August 2026 — expect to move your money again once the promo expires.

You have 20,000–50,000 PLN and don’t want to hit 10 card/BLIK transactions a month: Trade Republic (6%, no cap, no conditions) is the clear winner here — the only offer in this roundup with no strings attached.

You have more than 50,000 PLN: no single promo will cover the whole amount. Consider splitting your savings across 2–3 accounts (see the deposit-guarantee section below), or pairing a savings account with a fixed-term deposit — more in Savings Account vs Fixed-Term Deposit.

You don’t want to track any activity requirements: Trade Republic wins again — it’s the only entry in the ranking listed with “none” under requirements.

What You Actually Earn — Effective Rate, Not the Ad

Back to Ola and her 60,000 PLN in BOŚ Bank (7% up to 15,000 PLN, 2% above):

15,000 PLN × 7% = 1,050 PLN gross interest per year
45,000 PLN × 2% = 900 PLN gross interest per year
Total: 1,950 PLN gross — an effective 3.25% annually on the whole balance, not 7%

After the 19% capital gains tax, that leaves 1,579.50 PLN net, or a real 2.63% annually. Still better than a standard current account (0.1–0.5%), but far from the headline number.

The same math applies to every capped promotion. Before comparing offers, calculate the effective rate for your balance — not the advertised one.

Deposit Guarantees and Spreading Your Savings

All banks operating in Poland (including foreign branches like Trade Republic or VeloBank) are covered by the Bank Guarantee Fund (BFG) up to the equivalent of €100,000 per customer per bank (roughly 430,000 PLN at current exchange rates). For typical balances (up to 100,000–150,000 PLN) that’s not a concern — but if your savings approach that threshold, splitting them across 2–3 institutions makes sense regardless of interest rates.

A bonus of splitting: you can use several “new money” promotions at once instead of leaving everything in one bank at the standard rate.

Checklist Before Opening an Account

I’ve checked the standard rate (after the promo ends), not just the headline number
I know the cap covered by the high rate
I know whether it applies only to new money, or to my full balance
I’ve checked the activity requirement (card/BLIK transactions, salary deposit) and can realistically meet it
I’ve calculated the effective annual rate for my own balance, not the advertised one
I know when the promo ends and what I’ll do next (move the funds? stay at the standard rate?)
I’ve checked that my total savings in this bank stay within the BFG guarantee limit

Common Traps

“7% with no conditions at all” — if an offer sounds too good, check the fine print. As of July 2026, the only genuinely condition-free offer is Trade Republic at 6%, not 7%.

Missing the promo expiry date. Without a reminder, your money will quietly drop to the standard rate (often below 1%) and sit there for months before you notice.

Opening an account for the rate alone, without checking the bank. Make sure the institution holds a KNF license and is covered by the BFG — this matters especially for lesser-known players and lending platforms outside the guarantee scheme.

Rate-chasing without doing the math. Moving 50,000 PLN between banks every 3 months for an extra percentage point nets roughly 500 PLN gross a year — plus hours of paperwork. Sometimes worth it, sometimes not.

FAQ

Could savings account rates rise further in 2026?

It depends on Monetary Policy Council (RPP) decisions. The NBP reference rate has held at 3.75% since March 2026, and most analysts don’t expect changes in the near term. Promotional offers well above that level (6–7%) are marketing, not a reflection of market rates — they can disappear as quickly as they appeared.

Yes, as long as you actually calculate the effective rate and factor in the time spent on paperwork. For balances around 20,000–50,000 PLN, a 3-month promo at 6–7% can make a meaningful difference over the standard rate — provided you meet the activity requirement without extra effort.

What’s the difference between a regular savings account and a “no conditions” one?

Accounts like Trade Republic’s don’t require current-account activity, a balance cap, or new-customer status — interest accrues on every złoty, daily. In exchange, the rate is usually lower than headline promotions with conditions (6% vs 7%), but it’s reliable and doesn’t require tracking deadlines.

Interest already accrued stays yours — you don’t lose it. Only the rate used going forward changes. That’s why it’s worth setting a reminder for the promo’s end date and checking whether it’s time to move your funds elsewhere.

Is it better to pick one account with the highest rate, or split savings across several banks?

For balances up to about 50,000 PLN, one well-chosen account (mindful of the cap) is usually enough. Above that, splitting across 2–3 banks lets you use several “new money” promotions at once while staying within BFG guarantee limits.

Summary

A bank ad’s headline “7%” rarely matches what actually lands in your account. Before you decide:

Calculate the effective annual rate for your specific balance, not the advertised one
Check the cap, promo period, and new-money condition
Confirm you can meet the activity requirement without artificially generating transactions
Set a reminder for the promo’s end date so you don’t get stuck at a 1% rate

If you’d rather not track promo deadlines manually, save your savings goal in Plutario and set a reminder for the day your promo ends — that way you make the “stay or move on” decision deliberately, not by accident.
