What has to be true?

Short, practical breakdowns of the numbers hiding inside familiar money advice.
$83 less per month≈$999 more interest
A lower payment can still cost more.
On the same $30,000 auto loan at 6% APR, 72 months lowers the payment compared with 60 months—but adds 12 payments and about $999 in interest. Compare total cost, not only the payment.
