APR vs AER

APR applies to borrowing. AER (Annual Equivalent Rate) applies to savings. Both allow like-for-like comparison on their respective sides of your finances.

How to Use APR to Save Money

Always compare APR not just the monthly payment
For 0% cards check the revert rate when the deal ends
For mortgages compare APRC not just the headline rate
Always check total amount repayable alongside APR

Bottom line: APR is the most important number when comparing borrowing. A loan with a lower monthly payment but higher APR costs more overall. Always compare APR and total amount repayable before committing.
