    "summary": "APR is the yearly rate that makes your loan payments worth exactly the money you actually receive. Upfront fees reduce what you receive, so the APR comes out higher than the interest rate.",

    "interpretation": "Compare loans of the same length by APR rather than by interest rate: it puts fees and rate on one scale. Fees weigh more heavily on short loans, so a fee that adds 0.2 points to a 30-year APR can add a full point or more to a 3-year loan.",

            "answer": "APR multiplies the monthly rate by 12. The effective annual rate compounds it: (1 + monthly rate)^12 − 1, which is slightly higher."
