Frequently asked questions

What APR is good for a personal loan?

It depends on credit; compare the APR, which includes fees, across several lenders.

Can I pay off a personal loan early?

Most lenders allow it without penalty; check the agreement for a prepayment fee.

Is this interest simple or compound?

Payments follow the standard amortization formula, with interest charged monthly on the remaining balance.
