How the payment is worked out

A level payment loan has a neat rule behind it. Each month the interest is the balance times 0.5417 percent. The payment is set so that after 48 months the balance lands exactly at zero. Solving for it on $30,000 gives the loan times the monthly rate, divided by one minus one over one plus the monthly rate raised to the power of 48.

Worked example

Work it through with $30,000, 6.5 percent and 4 years. Each payment is $711.45. The first one sends $162.50 to interest and the remaining $548.95 to principal.

Part of the way through, after 2 years, the balance is still $15,971. That is 53 percent of the original loan. Early payments mostly cover interest.

Questions about this calculator

Is 4 years the right length for a $30,000 car loan?

It depends on the monthly payment you can carry. At 6.5 percent this term costs $711.45 a month. A 6-year term would cost $504.30 a month and $6,309 in interest, compared with $4,150 over 4 years.

Does adding a year to a $30,000 car loan over 4 years change the cost much?

Yes. At 6.5 percent a 4-year term costs $4,150 in interest. A 5-year term would lower the payment to $586.98 but raise interest to $5,219.

Should you put more down on a $30,000 car loan over 4 years?

A bigger down payment means borrowing less. On this $30,000 loan, putting down $3,000 more would lower the payment by about $71.14 and the interest by about $415. Sales tax, fees and insurance are not included.

What if the rate on a $30,000 car loan over 4 years were one point higher?

The payment would rise from $711.45 to $725.37, which is $13.92 more each month. One point lower would give $697.69.
