What a personal loan costs in Antioch
Personal loans are closed-end installment debt, so the monthly payment and the payoff date are known from the start.
Because the APR includes origination and finance charges, it is the honest comparison number; the personal loan calculator turns an APR and term into a monthly payment.
Stretching the term lowers the monthly payment but raises the total interest you pay, so the smallest payment is not automatically the cheapest loan.
If you are consolidating debt, the loan only helps if you stop adding to the balances it clears; otherwise the total debt grows.
