Domande frequenti
What's the difference between APR and interest rate?
APR includes fees and is more realistic. Nominal rate = APR without fees. APR typically higher.
How is credit card interest calculated?
Daily balance method: (balance × daily APR × days in period). APR / 365 = daily rate.
Can paying minimum balance avoid interest?
No. Interest accrues on remaining balance. Minimum payments mostly cover interest, little principal.
