  • What is APRC?

    Annual Percentage Rate of Charge (APRC) is a calculation of the overall cost of a loan expressed as an annual rate. It takes into account all costs involved over the term of the loan, such as the interest rate, valuation fee and mortgage charge paid to the Property Registration Authority. We calculate it to a standard set out in consumer protection legislation.
