Basic  Calculating Interest And Time Till Pay Off
Feb 20, 2014
I've uploaded my spreadsheet. I asked my professor if our formula had to take into account whether or not our payment would be changing. As long as I calculated the initial amount  which worked out to be around 30 dollars, I could assume I paid that amount for the entirety.
ASSIGNMENT 4
My latest Mastercard statement shows a balance due of $1,696.96.
Based on recent bills, assume that the minimum payment amount is computed as follows
(balance_owed)*(annual_interest_rate/12) * 2, then rounded to the nearest whole dollar amount.
The minimum payment amount is the amount calculated above or $25.00, whichever is the greater amount.
The annual interest rate for purchases is 11.24%. If I make no more purchases and always pay my bill on time how many years and months will it take be pay it off at the current minimum payment amount each month?
How much total interest would I pay if I repay the loan this way?
What fixed monthly payment amount would pay off the debt in 2 years?
Assume monthly compounding of interest. All calculations are to be done in the Excel worksheet.
The functions NPER() and PMT() will be useful. Note that either the Present Value or Payment amount should be negative (not both) because of conventions concerning the direction of cash flow."

I have a column of years and a column of numbers representing annual
amounts placed in a savings account for the year. I would like to calculate
the balance of interest earned added to the balance of the account and then
calculate the interest earned on the accumulating amounts each year. The
results would be the account balance displayed in an adjoining column. So
far, I have not found a worksheet function for that. Could someone point me
in the right direction? Perhaps there should be several columns of data?

I use Excel 2007 , I created Interest calculator , on Daily basis , to caluculate interest , compounded quarterly.
But I want to make it compact , as d one I created is long enough.
A3 = Principal Amount
B3 = Date of Investment
C3 = Interest as on Date
D3 = Number of Days , amount Invested {comes out of formula set}
E3 = Rate of Interest
Now in F3 I want the Interest amount , compunded quarterly.
Some times NUMBER OF INVESTED CAN BE LESS THAN 90 DAYS TOO...then what ?

If I invested $350 per hectare into a project and at the end of 12 years that investment yielded me $150,000, what would my rate of return be over the life of the project?

I have developed a financial calculator that asks the user for the "input date" which is used to record balances as of the input date. My interest calculation for the first year is based on the current date compared to the input date. For example, if the user is keying in a current balance of 10,000 @ 10% interest, and the "statement date" or "input date" is 12/30/2013, and the current date is today, 2/4/2014, then it should calculate interest for the entire year of 2014. It is not doing that. It calculates $3 interest.
But if input date is 6/30/2013 with current date of 2/4/2014, it seems to work OK. It calculates interest of $504 in that case. It appears to get messed up with the year transition between current date and input date. The formulas I have listed below appear to work fine except when the input date is 2013 for the year and the current date is 2014. The formula does not "see" that input date was last year. There must be a minor tweak to formula I am overlooking.
Cell C2 = Today's Date=TODAY()
Cell C3 = Input date (user keys in date in mm/dd/yyyy format)
Cell E2 = "translate input date to year format" =DATE(YEAR(C3),12,31)C3
Cell E3 = Investment Rate
Cell G2 = yr 1 interest rate adjusted =(E3/1)*($E$2/365)
Cell C21 = Current Balance
Cell D21 = Interest Yr1 = C21*G2
I need the interest calculation to account for partial year accrual.

I keep coming across bonds having different annual interest rates and different compounding frequencies (quarterly, half yearly and yearly).
I know there is a YIELD function, but it requires so many inputs. I was wondering whether we can calculate cumulative yields just from annual interest rates, compounding frequency and investment duration?

I create this spreadsheet as a loan schedule using average daily balance method. (1/payment is constant, fortnightly 2/interest is 5.5% per annum)
In the interest column, at the beginning of each month ( when the day is 1) the interest will be added up from calculation of previous month daily balance.
My idea is that at interest column(let start at 1/08/2013) if (day(A49)=1, average the 30 or 31 cells above E49, 0).
I will manually make adjustment for February where 28 or 29 days applicable.

I have a problem calculating a total interest for an input period that has different interest rates. You can see the attached file: INTEREST.xls
I have used a function but the result comes out wrong. Can I fine tune it or do I have to change my method of calculating.

I am having a little trouble with a spreadsheet I am creating, the formulas and cell formatting I should be using to enable this to work.
Here goes:
in cell E3 I have a time started (e.g 12:45 pm), In F3 i have time finished (e.g 2:30 pm)
So, what i'm wanting is the time taken in G3 and also, i have the amount of units that is entered manually in H3. I would like I3 to show the time taken per unit.

I know the title is a bit vague, but I cant think how else to word it!
I have a sheet (attached) which works out hours worked, and if the amount is under a specified target, it counts how much time is owed. The problem occurs when someone works more hours than the specified target.
I guess I need an IF formula of some kind, to say if the figure is over the target, to put zero in the hours owed column.

I would like to do is develop a stand alone program in Visual Basic ( not in Excel VBA) to update the price file in our Portfolio system automatically using the downloaded Excel format file csv extention file from the BigCharts. But before that, I need to export the *.pri file from our Portfolio system in to Excel which still saves as *.pri extention. Then once it updates, I import the updated *.pri file back in our Portfolio program. I understand that the Excel VBA code can be incorporated in Visual Basic code provided there is an object declaration for Excel file (In this case eventhough the both files are in Excel format, they don't have xls extention). how to use external files and Excel VBA code in Visual Basic?
Below is the code that I currently have in Visual Basic. What I'm trying to accomplish is using the ticker (eg. msft) as a keyword search to look up in the price file. If found , the price of that ticker from the test.csv file will be copied in to the price file which is test.pri. I haven't ran it yet.
Sub UpdatePrice(BigChartPath As String, BigChartName As String, AxysPricePath As String, AxysPriceName As String)
'Below are Excel VBA codes
'Uses the test.csv to look up tickers in test.pri and update the price in it
Dim PriceFile As Workbook, BigChartFile As Workbook
Dim PriceFileSheet As Worksheet, BigChartSheet As Worksheet
Dim MaxRows As Long
Dim PriceFileRow As Long
Dim BigChartRow As Long
Dim BigChartFound As Boolean
Call CheckBookOpen(BigChartPath & BigChartName)
Call CheckBookOpen(AxysPricePath & AxysPriceName)
Set BigChartFile = Workbooks(BigChartName) 'Big Chart website imported CSV file saved as test.csv...............

Firstly, i'd like cell G5 to show the amount of time worked i.e diff between E6 & F6. Secondly I'd like help with the formula for cells AF6 & AG6 which would require AB6AC6 divided by the frames, every time I try it I get a messed up answer.

=INDEX({"$5.00","$3.00","You Were Late"},MATCH(L17,{7:00am,7:05am,7:06am},1))
i have this formula in excel...this formula sanrv1f posted to help with another question (values changed) but i thought i would work with what i wanted but i get a (Value) error
so what im trying to do is base on the system time is if the person typed in
if they were early 6:45am to 7am they get Extra $5 on top of the $5 they get for being on time.
6:55am gets $5
7:00am they get $5.00 for being on time
if they type 7:01am to 7:05am they get $3.00
if they type 7:06 to 7:10am would return You Were Late
after 7:10am would return No Pay
so Ex
D4 *answers in E4 *
7am would get $5
7:03am am would get $3
7:07am would get You Were Late
7:11am Would get No Pay
if they were on time 5 times (ie 5days in a row) they would get a bonus of $20 i tried factoring this in could not do it :/

basically I need an excel sheet to calculate the period of time between cells.
For instance, in A1 I write:
18Feb10
In A2 I write:
13:00
Unfortunately I cannot write 18Feb09 13:00 in just one cell because it doesn't work.
Now, in B1 I write 19Feb10
and in B2 I write 15:14
Now we know that 26 hours and 14 minutes have elapsed between these two times. So if I want this to automatically be calculated in B3, what do I do?
Also, how do I apply the formula to all cells in column 3 so all I have to type in is the date (in column 1) and the time (in column 2)?

I'm having a DICKENS of a time on this one. To explain, I have 3 columns where time is entered: a 'Time of Call', 'Time of Arrival', and 'Response Time'. The 'Response Time' cell autcalculates by simply subtracting the 'Time of Arrival' form the 'Time of Call' and using the difference to show the response time. To make time entry into the 'Time of Call' and 'Time of Arrival' simplier for my coworkers, I formatted those cells as 00:00 so that anytime you enter a number it will convert it to a time format (i.e., if you enter in the numbers 745, it will show as 7:45 in the cell). Because of this, when the response time is configured, it does it in hundreds instead of time format. So, if you enter in 7:45 as your time of call and 8:15 as your time of arrival, it shows 70 minutes as a response time because it sees the 7:45 as a whole number...745. Therefore, 815745 DOES equal 70, but...that's not what I'm looking for. I want it too configure this as time...not as whole numbers.

I'm trying to calculate the variance between planned date & time of arrival vs actual date & time of arrival.
I attach the workbook as am a bit useless at explaining myself....
What I've done is in H14 subtract the actual date of arrival (F14) from planned date of arrival (C14). This result is the only way I could think of dealing with crossing over midnight. As a result I14 should subtract the actual time of arrival (E14) from planned time of arrival (B14):
=SUM(E14B14,H14)
This method works well when the arrival was later than expected but doesn't work if the arrival was sooner than expected.

I'm calculating the difference in time:
9:549:45 = 0:09
Now to convert this in minutes (in number format), I multiply this number with 1440:
0:09*1440 = 9
When I click the cell this number is actually 9.0000005, rather than exact 9. I need it to be exact 9 since I have to match this number from other excel sheet.
To sum up:
This is what I expect:
31.99999 should be changed to 32
10.000001 should be changed to 10.

I managed to put together an array formula to calculate the last date that a rep made a sale. It checks two other tabs in the workbook to find the date, and if none is found, it leaves the cell empty.
{=IF(MAXA(IF('Daily Compliance'!A:A=B48,'Daily Compliance'!O:O),IF('Daily Compliance 1107 to 408'!B:B=B48,'Daily Compliance 1107 to 408'!A:A))=0,"",MAXA(IF('Daily Compliance'!A:A=B48,'Daily Compliance'!O:O),IF('Daily Compliance 1107 to 408'!B:B=B48,'Daily Compliance 1107 to 408'!A:A)))}
But it takes sometimes up to 45 minutes to make the calculations. Is there possibly a way to simplify it so that it calculates faster, with the same results?

I need to calculate an SLA.
I have 1 column called 'Date/Time Requested' containing the time and the date together, as in:
dd/mm/yy hh:00
I also have a second column called 'Date/Time Completed' containing the date and time in the same format as above.
I need a macro that compares the two and works out the following:
< 48 hours = "Within SLA"
> 48 hours = "Outside SLA"

I have a sheet to calculate Time Elapsed based on StartDT & EndDt taking into consideration the actual working hours in any working day and the function exclude the weekend. I am not a guru in excel but i found this formula in this website .
=IF(AND(INT(StartDT)=INT(EndDT),NOT(ISNA(MATCH(INT(StartDT),HolidayList,0)))),0,ABS(IF(INT(StartDT)=INT(EndDT),ROUND(24*(EndDTStartDT),2),
(24*(DayEndDayStart)*
(MAX(NETWORKDAYS(StartDT+1,EndDT1,HolidayList),0)+
INT(24*(((EndDTINT(EndDT))
(StartDTINT(StartDT)))+(DayEndDayStart))/(24*(DayEndDayStart))))+
MOD(ROUND(((24*(EndDTINT(EndDT)))24*DayStart)+
(24*DayEnd(24*(StartDTINT(StartDT)))),2),
ROUND((24*(DayEndDayStart)),2))))))
the formula works perfectly except for the fact that in our part of the world we have "Friday & Saturday" as the weekend days instead of Saturday and Sunday.
is there a way to get this formula or any similar formula to take different weekend days and do exactly what i need?

I am trying to calculate the amount of time in blocks, using a predetermined spread. For example:
AM block is anytime between 06001230
PM block is anytime between 12301830
Evening block is anytime between 18300000 and the Overnight block is anytime between 00000600
Sounds easy enough, yeah? Let me paint an example of how I want it to calculate though:
If an employee starts at 0600 and finishes at 1400, then the AM total is 6.5 and the PM total is 1.5.
If an employee starts at 1100 and finishes at 1900, then the AM total is 1.5, the PM is 6 and the Evening is 0.5.
If an employee starts at 2200 and finishes at 0800, then all of the 10 hours must report to the Overnight total, even though some of them fall within the Evening and AM blocks.
I just can't seem to get each block to show the accurate number of hours...and to bring in the rules that I require.

I am trying to write what I believe is a fairly simple set of calculations to determine nonqualified stock option values. Before this digresses into a discussion of the merits of BlackSholes methodology, I must tell you that this is a "101" type sheet. I'm not an economist.
The deal is that my sister (for whom I'm constructing this worksheet), gets employer stock options which vest at different intervals.
In the past year, she's gotten some options that vest in two, four, and five year increments. I'm using Excel 2002, with the analysis toolpak, and stock pricing addin from MS.
Have today's date, date of option grant, and can easily compute time (in years) until options are fully vested.
The trick is that options with a 2year vesting period are 50% excerciseable in one year, 100% in two.
Fouryear options are excerciseable 25% per year for 4 years; 5year are 20% for 5 years, etc.
I'm trying to write a single datedriven formula to take each grant (individually), and divide it by the appropriate divisor (based on the current date), to figure out the current value.
I can't seem to quite figure it out how to write a formula which can handle:
Shares Strike Price Date of Grant Years Until Vested Value
100 26.57 1/4/2003 5
245 45.67 2/6/2001 4
Value should equal =
(if today's price is grater than Strike Price)
(Current Price * (Shares * (% vested which is based on "date of grant" + "years until vested")) )

(Strike Price * Shares * (% vested which is based on "date of grant" + "years until vested") )
how the math to make the "% vested multiplier" work...

I have redundant system groups. One group may have (for example) two computers running. Another group may have eight computers running. But within any group only one computer needs to be running for the system to be operational.
I have a row with down start date/time (ColumnA) and down end date/time (ColumnB) for each downtime event. In then next columns I have the start times and end times for the other computer(s) in the group.
Finally, I have a date column to the right of all others (one row per day). Next to the date column I need to have the value that represents the common time all computers in that group were down.
I don't much care if this is done with a formula or by VBA. I can split the date and time values into separate columns and format the values however needed to facilitate the calculation.
I've placed an example workbook at the following location. [URL] ...
