Frequently asked questions

Why is the APR so high?

Because the fee is charged on a very short loan. APR spreads it over a full year to compare with other credit.

What is the effective annual rate?

It compounds the fee over a year, which shows what the cost would be if you kept renewing the loan.

Are there cheaper options?

Often yes: a credit union loan, a payment plan or help from local programs.

Is the APR the same as the fee?

No. The fee is a one-time charge for the loan. APR is the yearly equivalent.
