Cash Back vs Low Interest

When purchasing a vehicle, manufacturers often offer a choice between a cash rebate (cash back) or a low-interest financing rate. The best choice depends on the rebate amount, the promotional interest rate, the loan term, and the buyer's ability to invest the rebate or use it as a larger down payment.

As a general rule, the low-interest option is more valuable when the promotional rate is significantly below market rates and the loan amount is large. The cash rebate may be more advantageous when the rebate is substantial, the promotional rate is not much lower than market rates, or the buyer plans to pay cash or has alternative financing.

The calculator helps compare these options by computing the total cost under each scenario, accounting for the time value of money. Buyers with excellent credit who can qualify for the promotional rate may benefit more from financing, while those paying cash or with shorter loan terms may prefer the rebate.
