Rebate or low interest rate? Which is Better: A Rebate or a Low Introductory Interest Rate? Automobile manufacturers and dealers use a variety of marketing devices to sell cars. Among these are rebates and low-cost dealer-arranged financing packages. To determine which method of reducing the vehicles cost is better, you can use the following equation that considers the amount borrowed (D), the interest rate on the loan (APR), the number of payments made each year (Y), the total number of scheduled payments (P), and any finance charged in the transaction (F): APR APR = = Y (95P+9) F12P (P+1) (4D+F) Y 95P + 9 F 12P P + 1 4D + F You and your friend, Danny, have been shopping for your new car for several weeks.
