Auto Loan Payment Chart: Monthly Payment per $1,000 Borrowed

Quick answer: To estimate any car payment, multiply the amount financed (in thousands) by the factor in the chart — e.g. a $25,000 loan at 7% for 5 years is 25 × $19.80 ≈ $495/month. The second table shows total interest on a $30,000 loan: the same 7% loan costs $5,642 over 5 years but $8,034 over 7 years.

Every fixed-rate auto or personal loan follows the same amortization math, which means you can estimate any monthly payment from one small table. These figures are computed with the standard formula lenders use.

Monthly payment per $1,000 borrowed

Multiply the factor by your loan amount in thousands. A $25,000 loan at 7% over 5 years: 25 × $19.80 ≈ $495/month.

APR	3 yr	4 yr	5 yr	6 yr	7 yr
4%	$29.52	$22.58	$18.42	$15.65	$13.67
5%	$29.97	$23.03	$18.87	$16.10	$14.13
6%	$30.42	$23.49	$19.33	$16.57	$14.61
7%	$30.88	$23.95	$19.80	$17.05	$15.09
8%	$31.34	$24.41	$20.28	$17.53	$15.59
9%	$31.80	$24.89	$20.76	$18.03	$16.09
10%	$32.27	$25.36	$21.25	$18.53	$16.60
12%	$33.21	$26.33	$22.24	$19.55	$17.65

Total interest on a $30,000 loan

The same loan gets dramatically more expensive as the term stretches:

APR	3 yr	4 yr	5 yr	6 yr	7 yr
4%	$1,886	$2,514	$3,150	$3,794	$4,445
5%	$2,369	$3,162	$3,968	$4,787	$5,617
6%	$2,856	$3,818	$4,799	$5,797	$6,814
7%	$3,347	$4,483	$5,642	$6,826	$8,034
8%	$3,843	$5,155	$6,498	$7,872	$9,277
9%	$4,344	$5,834	$7,365	$8,935	$10,544
10%	$4,849	$6,522	$8,245	$10,016	$11,835
12%	$5,871	$7,921	$10,040	$12,228	$14,485

The headline finding: at 7% APR, taking a $30,000 loan over 7 years instead of 3 lowers the payment by about $500/month — but costs an extra $4,687 in interest (from $3,347 to $8,034), 2.4× as much.

How to use these tables

Budget-check a car before the dealership. Work out the payment yourself so the finance office can't hide a longer term behind a "low monthly."
See what a rate change is worth. On $30,000 over 5 years, dropping from 10% to 7% saves about $2,603 in interest — that's what refinancing or a better credit tier buys you.
Choose the shortest term you can afford. The second table is the real cost of stretching payments — see short vs. long terms.

Frequently asked questions

How do I estimate a car payment quickly?

Multiply the amount financed in thousands by the per-$1,000 factor for your rate and term. Example: $20,000 at 8% for 6 years = 20 × $17.53 ≈ $351/month.

How much more does a longer car loan cost?

On a $30,000 loan at 7% APR, total interest is $3,347 over 3 years, $5,642 over 5 years, and $8,034 over 7 years — the 7-year loan costs about 2.4× the interest of the 3-year loan for the same money.
