Credit card vs debit card abroad — which is actually better?

The question of credit vs debit for overseas travel sounds simple but has several layers. Forex fees, purchase protection, cash advance traps, ATM access, and insurance benefits all factor in. The right answer depends on your destination and spending pattern.

Forex fees: it depends on the card, not the type

Both credit and debit cards can charge zero forex fees. Starling (debit) charges nothing. Wise (debit) charges nothing on spending. Scapia (credit) charges nothing. Halifax Clarity (credit) charges nothing. The card product matters far more than whether it's credit or debit. However, most standard credit cards from traditional banks charge 2.75–3% on overseas transactions — the same or slightly higher than debit cards.

Purchase protection: credit wins clearly

Section 75 of the Consumer Credit Act (UK) gives credit card holders powerful protection on purchases between £100 and £30,000. If a merchant fails to deliver, goes bust, or provides something materially different from what was sold, your credit card issuer is jointly liable. This applies to overseas purchases too. Debit card chargeback exists (via Visa/Mastercard's rules) but is weaker and more discretionary. For hotels, flights, tours, and high-value purchases, credit card protection is genuinely valuable.

Cash advances on credit cards: a trap to know

Using a credit card at an ATM abroad is almost always a bad idea unless you have a specialist card. Most credit cards treat ATM withdrawals as cash advances — which typically charge 3–5% upfront plus high interest from day one (usually 27–29% APR) with no interest-free period. Even good travel credit cards like Halifax Clarity charge a cash advance fee for ATM use. Use a debit card (Starling, Wise, Monzo) for cash withdrawals abroad — they're designed for it.

ATM access: debit wins

For cash withdrawals abroad, purpose-built travel debit cards are significantly better than credit cards. Starling gives free ATM withdrawals up to £300/day. Wise gives £200/month free. Revolut gives £200–400/month free depending on plan. No credit card matches this for cash. The Charles Schwab Investor Checking (USA) is the gold standard globally — unlimited ATM fee rebates on a debit card.

Insurance and perks: credit often wins

Many premium travel credit cards include travel insurance, flight delay compensation, purchase protection, and lounge access as part of the package. American Express Gold (UK), Chase Sapphire (USA), and similar cards offer substantial travel benefits for their annual fees. If you're spending enough internationally to justify the fee, these perks can outweigh the forex savings from a zero-fee debit card. The calculation depends on your spending volume.

The optimal combination

Most experienced travellers carry two cards: a zero-forex debit card (Starling, Wise, or Revolut) for ATM withdrawals and everyday spending, and a travel credit card (Halifax Clarity for UK travellers, Scapia for Indian travellers) for high-value purchases where Section 75 protection applies. This gives you the best of both: zero fees on spending, purchase protection on big items, and free ATM access for cash.

Specific situations where each wins

Debit is better: ATM withdrawals abroad, everyday spending in cash-heavy destinations, when you don't want to manage credit card bills. Credit is better: booking hotels and flights (Section 75 protection), destinations with poor ATM infrastructure where you'll spend on card, when you want travel insurance bundled in, when you're earning valuable rewards on a high annual spend.
