The method, explained
For each offer, calculate its amortizing payment. Total cost = payment × months + upfront fees. Difference = offer B total cost − offer A total cost; a positive difference means A has the lower undiscounted total.
Using amount borrowed = 20000 money, offer a annual interest rate = 6 %, offer a term in months = 48, offer a upfront fees = 500 money, offer b annual interest rate = 7 %, offer b term in months = 60, offer b upfront fees = 100 money, the result is 815.810362 currency. Change these example inputs to match your task; use the method above to check each step.
