Understanding UK Credit Card Debt in 2026
Credit card debt can be costly, but balances, rates and repayment terms vary between people and providers. What makes UK credit cards expensive: Interest, fees and charges depend on the card agreement, so check the provider’s current terms rather than relying on market averages. The FCA describes persistent debt as paying more in interest, fees and charges than in principal over 18 months. Firms have staged duties to contact affected customers and offer appropriate help, but this does not create an automatic right to an interest freeze. Regional debt patterns: Household circumstances and borrowing needs can differ across the UK, but unsupported regional balance estimates should not be treated as benchmarks. Age and debt trends: Credit use also varies with individual circumstances; age alone does not determine a typical balance or cause of borrowing. This calculator models one balance using an unchanged APR divided by 12, with no new spending, fees or rate changes. Its results are illustrations, not market statistics or affordability predictions.
