# Car Loan Calculator

- **URL:** https://codeasystem.com/calculators/finance/car-loan-calculator/
- **Category:** finance
- **Description:** Estimate the monthly payment and true total cost of financing a car, including the effect of your down payment.
- **Primary output:** Monthly car payment: $557.08

## Inputs
- Car price (name: `price`, type: number, prefix: $, example: 32000)
- Down payment (name: `down`, type: number, prefix: $, example: 4000)
- Interest rate (name: `rate`, type: number, example: 7.2)
- Term (name: `termMonths`, type: number, example: 60)

## Outputs
- Monthly car payment: $557.08
- Amount financed: $28,000.00
- Total interest: $5,424.77
- Total cost of the car: $37,424.77

## Formula / methodology
```
M = (Price − Down) · r / (1 − (1 + r)^−n)
```

Your down payment is subtracted from the price first; the remainder is financed with a standard amortizing loan. The “total cost” row adds your down payment back to all loan payments so you can see what the car really costs you.

## Assumptions & limitations
- Fixed APR, equal monthly payments.
- Taxes, title, registration and dealer fees are not included; add them to the price if you finance them.
- No trade-in or rebate modeled; fold those into the down payment.

## Example
A $32,000 car with a $4,000 down payment financed for 60 months at 7.2% APR runs $557.08 per month; $37,424.77 all-in including the down payment.

Result for these inputs:

```
Monthly car payment: $557.08
```

## About this calculator
### How much car can you afford?

A common guideline keeps total vehicle costs; payment, insurance, fuel; under about 15–20% of take-home pay. Long 72–84 month terms lower the payment but leave you owing more than the car is worth for years.

### Depreciation meets interest

Cars lose value fastest in the first years while interest charges are highest; the opposite of a house. Bigger down payments protect you from being underwater on the loan.

## FAQs
### Should I finance through the dealer or a bank?

Get pre-approved with a bank or credit union first, then let the dealer try to beat that rate. Compare APRs, not monthly payments.

### Is a longer term cheaper?

The monthly payment is lower, but total interest is higher. A 72-month loan at the same APR costs noticeably more overall than a 48-month loan.

### Do I need a down payment?

Some lenders allow zero down, but you start underwater due to depreciation and may face higher rates. Even 10% down meaningfully improves the deal.
