Does a longer loan term really make borrowing cheaper?
A longer term can make a monthly payment easier to manage while increasing the interest paid over time. Compare the payment and the total cost as separate results.

Hold the amount borrowed, contractual rate, interest convention and fee treatment constant, then change only the term. A smaller monthly bill on a larger or differently priced loan does not reveal which offer costs less. The basic calculator assumes monthly amortizing payments; a contract with daily accrual or a final balloon may need a different model.
Start with a zero-interest illustration
Borrowing 24,000 for 24 months at zero interest produces payments of 1,000. Spreading the same principal across 48 months gives 500 per month. Both repay 24,000, so the lower payment alone says nothing about a cheaper purchase. With a positive rate, the balance that remains outstanding for longer continues to generate interest. Run the two actual rates and terms to see the cost of that extra time.
Record three numbers before choosing
Write down the monthly payment, total interest and number of payments for each scenario. If the longer term creates useful cash-flow headroom, identify its purpose and check whether voluntary extra payments are permitted without charges. Do not apply a fixed-payment result unchanged to variable-rate, interest-only or balloon-payment borrowing. Any upfront fees should also be compared outside the interest-only model.
