APR solved from the daily payment stream over 21 business days a month. Weekly schedules give a slightly lower APR for the same factor.

In short

A factor rate multiplied by the amount borrowed gives the total repayment. A $50,000 advance at a 1.3 factor repays $65,000. Spread over 9 months of daily payments that is roughly an 80% APR; the same factor over 18 months is about 40% APR. The shorter the term, the higher the APR for the same factor rate.

How to use this calculator

Advance amount

What you receive before any origination fee is deducted.

Factor rate

Usually 1.1 to 1.5. Multiply by the amount to get total repayment.

Repayment period

How many months the daily or weekly payments run. Shorter periods mean a higher APR.

Origination fee

Often 2% to 5%, deducted from proceeds. It increases the effective APR.

If a provider shortens your term as a favor, your APR goes up, not down. The factor rate does not change.
Compare the APR here against the online term loans and lines of credit on our best-of pages before accepting.

Frequently asked questions

What is a factor rate?
A flat multiplier on the amount borrowed, expressed as a decimal such as 1.3. Unlike APR it does not account for time, so it understates the cost of short-term products.
Is a 1.2 factor rate good?
It depends on the term. Over 12 months, 1.2 is roughly 36% to 40% APR. Over 4 months it is well over 100% APR.
