These defaults use a 6.5% sales-tax assumption, $700 in fees, $186/month insurance, 1,000 miles/month, 25 MPG and a $900/year maintenance reserve.
Down-payment comparison on a $35,000 vehicle
These examples isolate the loan math. Taxes, registration, dealer fees, insurance, fuel and maintenance can increase the real monthly cost.
| Scenario | Amount financed | APR | Term | Payment | Total interest |
|---|---|---|---|---|---|
| $0 down | $35,000 | 7.0% | 60 mo | $693/mo | $6,583 |
| $3,500 down (10%) | $31,500 | 7.0% | 60 mo | $624/mo | $5,924 |
| $7,000 down (20%) | $28,000 | 7.0% | 60 mo | $554/mo | $5,266 |
| $10,000 down | $25,000 | 7.0% | 60 mo | $495/mo | $4,702 |
A down payment changes more than the payment.
Cash down reduces the loan balance dollar for dollar before interest is applied. That normally lowers both the required monthly payment and the total interest paid when the APR and term stay the same.
Do not empty your cash reserves just to hit a percentage.
A large down payment can make the financing look stronger while leaving you short on cash for insurance, registration, tires, repairs or an unexpected expense. The best amount depends on the rest of your balance sheet, not a single rule.
Cars can depreciate quickly. Putting more cash down can reduce the chance that the loan balance stays above the vehicle's value, but the tradeoff is tying more cash up in a depreciating asset.
FAQ
Is 20% down required on a car?
No. Twenty percent is a common budgeting guideline, not a universal lender requirement. Actual minimums depend on the lender, borrower, vehicle and loan.
Can I buy a car with zero down?
Some borrowers can qualify for zero-down financing, but financing more of the purchase usually means a higher payment, more interest and a greater chance of owing more than the vehicle is worth.
Should I put cash down or keep an emergency fund?
That is a personal cash-flow decision. Compare the interest saved by a larger down payment with the value of keeping enough liquid cash for emergencies and near-term vehicle costs.
