Pay Off a $15,000 Personal Loan at 18% APR

At 18% APR, a $15,000 personal loan accrues interest fast enough that the term length matters a lot. A shorter term on $15,000 costs more per month but meaningfully less in total interest at 18%.

$15,000 at 18% APR on a personal loan is calculated with standard monthly amortization, not daily compounding. First-month interest on $15,000 comes to around $225, and each subsequent month's interest charge shrinks as the balance is paid down on schedule.

Where a card lets you choose any payment level, a personal loan on $15,000 at 18% APR has one lever: paying more than the required amount toward principal.

One phone call settles whether extra principal on this $15,000 personal loan at 18% APR triggers any fee, most lenders on a personal loan like this don't charge one, but the note itself is the only source that actually confirms it.
