FAQ
When would I need APR from APY?
When calculating periodic interest payments or comparing products that quote APR (like loans) with those quoting APY (like savings).
What is the periodic rate?
The periodic rate is the APR divided by the number of compounding periods. It's the rate applied each period before compounding.
Does compounding frequency matter?
Yes, more frequent compounding creates a larger gap between APR and APY for the same quoted rate.
