Pros and cons
Lunar
Pros
- Interest is paid monthly on all current accounts, and the account is easy access, so the balance stays spendable.
- The monthly fee is DKK 0, so nothing is deducted for keeping the account open.
- Balances are covered by the EU deposit guarantee scheme, with protection of EU DGS up to EUR 100,000.
Cons
- Currency conversion costs 0% to 1%, and an exchange fee applies on non-DKK transfers, so spending abroad is where the cost sits.
- Support runs on email, chat and help centre only, with no phone line listed for problems the app cannot answer.
- The free cash machine allowance is DKK 0, so ATM withdrawals are not part of what the account gives you.
Mercury
Pros
- Business tools and accounting integrations are described.
Cons
- Mercury is a fintech platform, not itself a bank
- partner-bank protections are not platform guarantees.
Who each suits
Lunar
Who it suits
- Students and teens opening a first account, since Lunar lists expats, student and teen as its core groups.
- Expats living in Denmark who want local payment details, since transfers use your own IBAN (iban).
- Couples sharing a balance, since a joint account sits in the feature list (free atm, joint account and digital only).
Who should look elsewhere
- Shoppers chasing the top rate: Plazo ES advertises 24.19% and AXI Card Tarjeta y Credito 21.59%, both far above the 0.25% to 1% paid here.
- Anyone who wants included cash machine use or a phone support line, given the free ATM allowance is DKK 0 and support runs on email, chat and help centre.
Mercury
Who it suits
- US businesses comparing account-management, team-access and accounting-sync tools.
Who should look elsewhere
- Businesses requiring Mercury itself to be the deposit-taking bank or a platform-level protection guarantee.

Questions about each
Lunar
How much does it cost to keep a Lunar account?+
The monthly fee is DKK 0, so there is no charge for keeping the account open. The costs sit on money moving: currency conversion costs 0% to 1%, outgoing transfers carry a small fixed fee, and transfers in SEK, NOK and EUR are free while other currencies cost more. Non-DKK transfers also attract an exchange fee.
Is my money safe and who regulates the bank?+
Deposits are covered by the EU deposit guarantee scheme, with protection of EU DGS up to EUR 100,000. The account comes from Lunar Bank A/S, a bank based in Denmark that is supervised by the Danish Financial Supervisory Authority. The scheme behind it is the same one that backs deposits at other European banks.
When is interest paid and can I take money out?+
Interest is paid monthly on all current accounts, and withdrawals are open whenever you want, so nothing is locked in for a term. The account is easy access by design, and the rate type is variable, which means the interest can move instead of staying fixed.
Can I use cash machines with this account?+
The free cash machine allowance is DKK 0, so ATM use is not part of what this account gives you. That suits people who pay by card or mobile and rarely need notes. If you take cash out often, an account with a free cash machine allowance would serve you better.
