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.
