Brin Noren   My daily periodic rate is 0.02164% and my APR is 7.9%. What would be the interest/fee charged after 30 days on a %100 balance? - 11/18/2017 10:24:10 AM

Tom Boucek   My bank is offering 0% daily periodic rate on as much as a $10k loan until 11/2018. Does this mean no interest charged until 11/2018? - 4/12/2017 2:21:11 PM

Annie   APR - is the rate for the year not accounting for compounding interest DPR - is the rate for the day Effective interest rate - is the rate that accounts for the compounding effects of interest If you incl. interest applied on interest you will be paying more than the APR. Most credit cards calculate the rate daily and compound monthly because your closing balance at the end of each day could be different as you make additional purchases or payments. Jose you are paying far too much interest to carry a balance on your credit card. I suggest you switch or call the company to see what other options they have available to you. - 9/17/2014 9:03:13 PM

Reno   Jon, the banks use a calendar of 360 days to calculate DPR. - 2/14/2013 12:05:20 PM

aMINE   Or you can use the 'Effect' function in Excel as: =Effect(rate,365) - 2/20/2011 7:13:03 PM

Steve Shebroe   If I make a monthly payment at the begining part of the billing cycle instead of by the due date are there any interest savings on a card with a daily periodic rate. Thank you. Steve. - 7/13/2010 4:48:35 PM

Jason   You have to understand that credit Interest accrues daily. So for example if your Interest rate is 9.99 you daily periodic rate is 0.0274% or $3.12. So if you take $3.12 x 30, for 30 days in a month your monthly Interest is $93.60 a. - 10/28/2009 12:24:23 PM

Jose   My credit card charges me and APR 29.99%, the DPR is 0.08217%, my average daily principal balance is $1,913.62 so this month my finance charge was $157.42; Is that correct? I know how they got it 1913.62 x 0.08217 = 157.42 but shoudn't it be 1913.62 x (0.08217/100) x 30 = 47.17. - 9/9/2009 3:59:04 PM

Jon   My credit card company charges an APR of 7.99%, but the daily periodic rate they are charging me is 0.02218%. According to your calculator I am being charged an APR of 8.09%, not 7.99%. Are they cheating me? - 1/20/2009 2:07:54 PM

Bill T.   Phil, if you have not got your answer, you can take the DPR%, times 365 = APR% really close. - 11/3/2008 5:30:36 PM

phil   How do you convert the Daily Periodic Rate to the APR? - 9/18/2008 5:43:28 PM

Bill Tarvin   I just happen to find this tool, and have used it about 20 times in just a few days, it is very useful ...thanks for letting us use it free!! BT - 7/8/2008 9:04:51 AM
