The amount
Interest is charged on what you owe, so borrowing less is the only lever that reduces both the payment and the total cost at the same time. Fees and taxes rolled into a loan count as borrowing too.
Calculate it. Understand it. Pay less.
Six fast calculators and plain-English explanations for personal loans, cars, mortgages and debt payoff. No jargon, no sign-up, no credit check — just the honest math behind the monthly payment.

APR is the price of the money. A couple of percentage points sounds small and isn't — over a five-year loan it's often the single largest difference between two otherwise identical offers.
A longer term lowers the monthly payment and raises the total interest, because you carry the balance for more months. A cheaper payment is not the same thing as a cheaper loan.
On an amortized loan every payment is the same size, but its composition changes. Interest is calculated on the outstanding balance, which is at its highest right at the start — so early payments are mostly interest and late payments are mostly principal. That's not a penalty; it's arithmetic. It's also why an extra payment made in year one is worth several made in the final year: it cancels every future month of interest that portion of the balance would have generated. Open any calculator's amortization schedule to watch the split shift row by row.
