Fact checked

When your credit prevents you from qualifying for a traditional personal loan, an installment loan might be your only option when you need money fast. But with APRs in the triple digits, it can mean paying back double or even triple what you borrowed.

Before taking out an installment loan, use our calculator to ensure you can afford the monthly repayments. If not, you might want to continue comparing lenders to find one that better fits your budget.

Key takeaways

  • Use this calculator before you borrow — installment loans often carry triple-digit APRs, meaning you could end up repaying double or even triple the original loan amount.
  • Enter your loan amount, repayment term and interest rate to see your estimated monthly payment, total interest and full loan cost side by side.
  • Installment loans suit larger amounts over longer terms — for smaller needs under $500 repayable within a month, a payday loan may be more appropriate. Compare lenders once you know what you can afford.
