Frequently Asked Questions
What's the difference between APR and interest rate?
APR (Annual Percentage Rate) includes the interest rate plus fees and charges, giving you the true cost of borrowing. The interest rate is just the percentage charged on the loan amount. UK lenders must display the representative APR.
How do I convert monthly to annual percentage?
Multiply the monthly percentage by 12. For example, 2% per month = 24% per year. Note: This is a simple multiplication and doesn't account for compound interest.
Is this calculator suitable for UK loan calculations?
This calculator provides basic conversions. For UK loan calculations, always use the representative APR provided by the lender, which includes all fees and charges as required by UK financial regulations.
