The two numbers that decide
If you spend abroad or online in foreign currency, a card with ~0% FX markup saves more than any cashback program. Domestically, fee-free cards with modest rewards win for typical spending levels. Premium travel cards only pay off with genuinely high, frequent travel spend.
The traps
Partial payment (revolving credit) at 10–12% interest is the expensive trap – always pay the full monthly balance. Watch dynamic currency conversion abroad: always choose to pay in local currency.
One card, full visibility
Whatever card you pick, its statement belongs in your budget monthly – card spending is where budgets quietly leak.

The two numbers that decide everything
First, the annual fee. Swiss cards range from free basic cards to premium cards well above CHF 300 a year. A fee is only justified if the benefits you actually use – insurance, lounge access, cashback – exceed it in francs. Most people overestimate their use of exactly those benefits.
Second, the foreign exchange markup. This is the quiet one: a markup of 1.5 % to 2.5 % applies to every purchase in another currency, on top of any interbank spread. Someone spending CHF 8'000 a year abroad pays CHF 120 to 200 in invisible costs – often more than the annual fee that everyone compares carefully.
Everything else – points, cashback percentages, welcome offers – is secondary. Get these two numbers right for your own spending pattern and the ranking of cards usually reverses compared with the marketing material.
Credit card, debit card or neither
Swiss debit cards now work almost everywhere and carry lower or no fees, which makes them the better default for everyday domestic spending. Credit cards keep two genuine advantages: they are required for many hotel and car-rental deposits, and they offer chargeback protection when a merchant does not deliver.
Prepaid and multi-currency cards from neobanks are strong for travel because they cut the FX markup dramatically, but they rarely qualify for deposits and reservations. The practical setup for many households is two cards: one Swiss credit card for deposits and protection, one low-FX card for travel spending.
For expats, one warning: some Swiss cards require a residence permit of a certain type or a minimum period of residence before issuing a full credit card. A prepaid card as a bridge for the first months is normal, not a rejection.
Interest, instalments and the one rule that matters
Swiss credit card interest is capped by law but still high – substantially above any savings rate you can earn. Partial payment options are marketed as flexibility; in practice they turn a convenience product into an expensive short-term loan, and the balance can persist for years.
The single rule that keeps credit cards harmless: always pay the full statement, always by direct debit (Lastschrift). Automating it removes the decision entirely, which is the point – the risk with credit cards is never the card, it is the monthly choice about how much to pay.
In your budget, record card purchases in the month they occur, not in the month the statement is settled. Otherwise the budget lags reality by up to six weeks – long enough for a comfortable month to hide an uncomfortable one.
