What is Cash Back or Low Interest Calculator?
A Cash Back or Low Interest Calculator helps you compare two popular car buying incentives: taking a cash rebate or accepting a low-rate auto loan. It instantly calculates the total cost and interest paid for both scenarios based on your actual values.
This tool simplifies side-by-side analysis, offering a clear “best option” in seconds. You need only enter the car price, cash back offer, standard and low interest rates, loan term, and down payment—everything else is automatic.
Formula Behind Cash Back or Low Interest Calculator
The calculator computes monthly and total payments for both cases using the standard car loan formula: M = P × r × (1 + r)n / [(1 + r)n - 1], with 'P' as principal, 'r' as the monthly interest rate, and 'n' as number of payments. The “Cash Back” case deducts the rebate before financing at the normal rate; the “Low Interest” scenario uses the full price but at the special low rate. The option with the lower total paid is your winner.
