# Formula To Calculate Monthly Deduction Based On Date

Jan 30, 2013

I'm looking for a function that calculates a fee deduction based on the 28th of each month.

I'm paying back £200 on 28th of every month starting 28th Feb and was hoping that a formula could keep track of this...

How to do it but basically I'm trying to put a formula in D2 as follows:

If Today's date (C1) equals C2 I need B1 to reduce by the amount in B2

How to continue it calculating reductions per month by duplicating the formula...

## Writing Formula To Calculate Monthly Returns Based On Annual Growth Rate

Jul 10, 2014

I have a model that makes projections based on annual growth rates. However, I need to evaluate the data based on monthly intervals. With an 8% return on an investment of \$1,000,000 my ending balance at the end of the year should be \$1,080,000 and in year 2 it would be \$1,166,400 and so on. In order to evaluate the monthly data I need each month in year 1 to be based off \$1,000,000, so it would be 8%/12=.006666% or \$6,666.66 per month. The next year would be based off \$1,000,000 + (6,666.66*12) = \$1,080,000 and each month would be \$7,200.

## How To Calculate Future Dates From Start Date On A Monthly Cycle

Sep 16, 2009

I'm trying to combine monthly calculations with "today" and with "workdays"

Example:

start date = 01/01/2009

today's date 09/16/2009

formula result = 10/01/2009 ; or if 10/01/2009 is a Sunday, result = 09/29/2009 (not 02/01/2009, 03/01/2009, etc)

=edate gives me a month but it doesn't skip weekends or calculate beyond today's date

## Formula To Identify Data Type And Calculate Monthly And Cumulative Figures?

Jun 7, 2014

I receive monthly expenditure returns from different departments which I have to consolidate. The problem I'm encountering is that some departments submit their data as a monthly figure and some as the cumulative position. It would be useful if I had a formula that identified what data type was submitted and from that calculate both the monthly and cumulative figure.

If you look at the attached example I'd like to input a formula in columns I and J that uses the data contained in columns B to E to calculate the monthly and cumulative expenditure figures.

## Automating Monthly Budget Averages Based On Start And End Date

Jan 30, 2014

I am trying to create a document that takes our client PO amounts, tactics/spend line items, and dates from one sheet and averages them across the months that it is eligible, so we can know the total amount of money we can expect to go out from our clients each month.

For example:
Client1 Tactic1 StartDate EndDate TotalAmount
Client1 Tactic2 StartDate EndDate TotalAmount
Client1 Tactic3 StartDate EndDate TotalAmount
Client2 Tactic1 StartDate EndDate TotalAmount
Client2 Tactic2 StartDate EndDate TotalAmount

I have mostly figured this out in a really complicated way with many nested if statements, but there HAS to be a simpler way. There will be lots of hands in this document, so I would like to make it as simple and easy as possible.

## Producing Table Of Monthly Values Based On Monthly Growth Rate And Yearly Total

Mar 6, 2013

I have a table of yearly totals for the amount spent by x. I also have a growth rate for each month so for example in 2001 in jan the growth rate might have been 0.3% and feb 0.5% What I want to do is for each month based on the growth rate and the total produce a value for each month which sum to the total amount. It's also important to note that it restarts each year.

## Calculate Next Due Date Based On Start Date Frequency And Current Date?

Mar 9, 2014

I'm trying to workout how to take a known initial date a repeating frequency and work out the next due date from today.

Example

Initial Date :- 1st of January 2014

Frequency :- every 5 weeks

Current Date :- 9th of March 2014

Next Due date should be :-12th of March 2014 (if I worked it out correctly from my paper calendar)

I want to use a cell formula to do this for different initial dates and varying frequency periods (the frequency will always be whole weeks i.e. 1,2,3,4,5,6,7,8,8,10)

## Calculate Working Shifts Per Day From Monthly Report

Dec 31, 2009

I have table and need to take out montly total for each worker...

Now...
Each hours in day have own factor. (I need total hours per day but for illustration)...

So when worker works day shift from 8:00 to 16:00 it's easy... 8 hours
When works from 8:00 to 20:00 it's 8 hours + 4 afternoon hours
When works from 20:00 to 8:00 it's 2 afternnoon hours + 8 night hours + 2 day hours

Aditional problem is when day intercept holliday or sunday when that factors need to be included (if holliday is at sunday then it's like holliday).

Here is some attachment:

Book1.xls

I've also added last day of previous month and first day of next month because of night shifts than need to be calulcated. Therefore correct number of hours is 168 and not 188.

Below I calculated manually those numbers wich I want to be automated...

Also.. This is table I get.. If it's easier to make it somehow else, OK by me. And any number of aditional columns is not problem...

I only used Jan and Feb as an example. So as you see on the right side I will have all 12 months for the year and I just want all the totals for each month to auto calculate. I will have between 15 and 30 entries each month.

## Monthly Depreciation Of An Asset To Automatically Calculate

Jan 25, 2010

I am working on a depreciation schedule in which I want the monthly depreciation of an asset to automatically calculate and, if the asset is fully depreciation, caclulate a zero or the balance to be depreciation (if less than the monthly depreciation). Please see below example. As you can see my asset is fully depreciated at the end of February but because there remains a \$0.01, the formula is calculating another month in March and then reversing it in April (less the \$0.01). Here's the formula I'm using. What am I doing wrong?

Column H is March, Column C is my monthly depreciation, and column E is my beginning book value:

=-IF(ABS(SUM(\$F2:H2))>=\$E2,(SUM(\$F2:H2)+\$E2),IF(\$E2=\$C2,\$C2,\$E2)))

## Calculate The Monthly Repayments On A Loan Taken Out Over A Certain Amount Of Years

Feb 21, 2010

I need to calculate the monthly repayments on a loan taken out over a certain amount of years, which I can do fine.

I just cant get my head around how to calculate monthly repayments over a certain amount of years when the intrest is compounding annualy.

What I have so far:

p*(1+(r/100))^n
Where p is value of original loan, r is annual intrest rate, n is amount of years, and I am hoping I am right in saying this is the total repayable amount of the loan?

Then putting that aside I created a amortization table. (which I am certain i forgot to include compound intrest in!)

To keep it short i followed this guide for the amortization table.

and now I am so confused about if I should be using PMT, PPMT, NPER?!

## Calculate Monthly & Annual Returns Of Security Or Index

Jan 3, 2007

I feel pretty dumb asking a basic math question but I couldn't find the answer anywhere. I would like to calculate the monthly & annual returns of a security or index. When trying to calculate various indexes to insure my math was correct, my numbers never match that of yahoo or bloomberg's. If you could just start me down the path,

## Calculate Monthly Standard Deviation From Daily Data

May 11, 2008

I've daily data of a stock indices returns and I would like to calculate the monthly standard deviation. Currently, I'm using the following worksheet functions: =STDEVP(C2:C20)*SQRT(COUNT(C2:C20))

However, the range changes from month to month, which makes the process of calculating the monthly standard deviation to be quite tedious if I've about 10 years worth of data. I assume I could somehow substitute the range with a dynamic range, but I'm struggling to come up with the correct formulation that would do that.

## Calculate Future Value Of Monthly Recurring, Annually Increasing Payments

Sep 19, 2007

follows in paragraph 5 - but first, background!

I have a specific formula (received courtesy of some clever person here at Ozgrid (thanks!)) which I use to calculate the Future Value of a series of future payments that increase at a fixed annual rate and earn interest at a fixed rate.

Here it is: =Pmt1* SUMPRODUCT((1+Increase_in_payment)^(ROW( OFFSET(\$A\$1,0,0,Term,1))-1),(1+Return_on_investment)^(Term-ROW(OFFSET(\$A\$1,0,0,Term,1))+1))

(Example: \$1000 per annum (Pmt1) is invested for 20 years (Term). The interest earned on the \$1000 is 10% per annum (Return_on_investment). The \$1000 increases by 5% (Increase_in_payment) each year - i.e. 19 increases - answer: \$89,632 (rounded))

This formula assumes that the payment is made at the beginning of the period.

Question: I would like to change the formula to use MONTHLY payments made in advance, and interest earned on a monthly basis.

Because I REALLY do not know what the formula does, maybe I could ask for a detailed explanation thereof - maybe even from the person who supplied it to me (I cannot see who did!) - and then I can start fiddling with it myself if answers do not come.

Two previous posts of mine that dealt with somewhat different issues on the same formula are:

Determine Present Value From Future Value

## Calculate Formula According To Date

Aug 15, 2007

I am creating a proforma income statement for a business plan and need the cell values to calculate (or not) depending on the startup date that is entered on another sheet.

The following formula works if the value of Startup!\$C64 is "March", but if it's "February" it returns 0.

=IF(AND(Startup!\$C64<="March",Startup!\$D64=2008),Assumptions!\$S17*P\$3,0)

What I'm trying to do is have the cell on the income statement only perform the calculation if the startup date is earlier or the same as the month referenced in the formula.

Perhaps I can't use the "<" with text?

## How To Calculate The Week Number Of The Month Based On A Date

Dec 30, 2013

I would like to calculate the week number of the month based on a date.

Now my days would only include working weeks (Monday - Friday).

Supposed the date is 12/31/2012:

M
31-Dec
T
1-Jan
W
2-Jan
TH
3-Jan
F
4-Jan

Since it only occupies 1 day of the workweek, then it will be considered as Week 1 of January. If the date is 1/28/2012:

M
28-Jan
T
29-Jan
W
30-Jan
TH
31-Jan
F
1-Feb

It will be considered as Week 5 of January since it occupies 4 days of the working week. If the date is 4/29/2013:

M
29-Apr
T
30-Apr
W
1-May
TH
2-May
F
3-May

It will be considered as Week 1 of May since it occupies only 2 days of the working week.

Basically if the date's month occupies 3 or more of the working days of the workweek then it will be considered as part of that month's working week. Is this possible with formulas? I tried to explain it the best I can.

## Calculate Numer Of Paychecks Based On Date Of Hire

Aug 22, 2009

I have a business and i run payroll for my employees twice a month (semimonthly).
Date of paycheck will be 16th and 31st.

(1st paycheck from 7/1/2009 to 7/15/2009
2nd Paycheck from 7/16/2009 to 7/31/2009
3rd Paycheck from 8/1/2009 to 8/15/2009)

i need to know the # of pay checks for each employee computed in Cell C3 to C7.

## Calculate Holidays Remaing Based On Start Date

Nov 21, 2007

I want to create a formula that will do the following Each worker is entitled to 21 days holiday per year this will run from 8 Jan 08 to 7 Jan 09. But if a worker starts say 15 Apr 08 he would be entitled to less than 21 days. I would just like to be able to put his start date in a cell and then automatically generate how many days holiday he would be entitled to from 15 Apr to 7 Jan.

## Date/calculate Elapsed Time Formula

Feb 16, 2010

I have been asked to make some ammendements to a workbook currently in use.

I have to calculate elapsed time, and my formula is giving me odd results. I have a start time (cell B5), and an end time (cell F5). The formula being used was =IF(F5>0,((F5-B5)*24)) which gave the correct result. The cell is formatted as general. It didn't alot for the situation where the end time has not happened yet.

I changed the formula to =IF(F5>0,((F5-B5)*24),(K5-B5)*24) where cell K5 is the current time. The results are coming out with 6 - 9 decimal places. It makes no sense as I've tried setting the times to be exactly 24 or 48 hours to the minute. I've also tried replacing K5 in the formula to now(),

## Formula To Calculate Date End Of Prev Month

Feb 22, 2008

I have a worksheet where the current months date is entered in cell E1 (format dd/mm/yyyy) , using an input box.

I need a formula the will calculate the previous months month end date in cell A6 and the month end prior to the date calculated in A6 in cell A13.

where the dates start with 31 for eg 31/01/2008 , then my formula works, but if it starts with 30, 29 or 28, then obviously it does not work.

I would like a formula that will calculate these previous month end dates correctly.

See example below ....
