Glossary term
Down Payment
A down payment is the cash you pay upfront toward a purchase, such as a car or home, so you borrow less. A larger down payment reduces the loan principal, the monthly payment and total interest, and it lowers the chance of owing more than the item is worth. It can also help you qualify for a better rate.

How Down Payment works in practice
The amount financed is the price, plus taxes and fees you choose to finance, minus your down payment and any trade-in value. Because interest is charged on that balance for the whole term, every dollar put down saves the interest that dollar would have accrued.
Buy a $32,000 car with a 60-month loan at 7.00%. With 20% down ($6,400), you finance $25,600 at $506.91 a month and pay $4,814.60 in interest. With 10% down ($3,200), you finance $28,800 at $570.27 a month and pay $5,416.20, so the extra $3,200 down saves $601.60 in interest and $63.36 a month.
A bigger down payment is not always better if it drains your emergency fund. The right balance depends on your cash cushion, the loan rate, and how quickly the item loses value.
Down Payment: quick questions
Does a trade-in count as a down payment?
Trade-in equity reduces the amount financed the same way cash does. Negative equity on a trade-in does the opposite.
Is a bigger down payment always better?
It saves interest, but keeping enough cash for emergencies matters too. Weigh both.
Can a down payment lower my interest rate?
Sometimes. A lower loan-to-value ratio reduces the lender's risk, which may earn a better rate.
