Am trying without success to create a formula to calculate average daily balance from a ledger that has a variable amount of entries per month. The variability of # of entries has me stumped. For example:
date, amount
1/1/2005, 10
1/5/2005, 1
1/10/2005, 4.65
1/18/2005, 7
1/22/2005, 20
Aver Daily Bal = 23.78. and I can get this easily manually, but I'd like a more automated solution. I'm trying a sumproduct angle, to no avail.
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 need to count the daily average of a task to a week ending number.
I need to see the current average after each day during the week. Example – Mon = 2, Tues = 4 AVERAGE is 3 – Wed = 2 AVERAGE IS NOW 2.6…and so on averaging out after each day is added.
How to go about fixing my spreadsheet so I am not having to manually update it each day..here is my forumla I am currently using...=(AVERAGE($D$2:$AH$2)-C5)*AI5...basically i need the cell below in D2 to change as every day a new day rolls off..for example the following day I need this formula to be =(AVERAGE($E$2:$AH$2)-C5)*AI5 ....so just that day changes.....do I need to use an If/then statement? if so how?
I have a table of data covering the last 9 months based on values automatically collated from 15 minute intevals.
The date/time is in column A (01/01/2009 00:00) with the data collected in column D.
My wish is to get the average daily data from column D and I am slowly losing my head!!!
Is there anyway of getting a formula to auto-average the daily values bearing in mind there are currently 96 daily entries.
I have tried converting the first 5 digits of column A to numeric (i.e. 31894 for 01/01) then trying to write a formula saying =average(D1:D24577,if(range="31894",1)).
I can now see a simpler way but am so confused after an hour or so of trying.
Each day has 96 readings so I need an auto adding formula. average column cell A would say =average(D1:D96).
Is there are way to have the cell below auto-update itself to look at the next 96 values and so on and so forth?
For the small database in my example workbook, I would like to apply credits earned at a later date to the oldest charges and create a "To Date" balance. After creating the "To Date" balance, I would like to select the smallest "To Date" balance as a way to identify the first charge that has no payment. Please see the attached for more clarity and additional information. The last column shows the desired results.
View 9 Replies View RelatedI am performing a given exercise every day in the month of march. I have the dates all lined up in my spreadsheet, with the sum at the bottom. What I want to do is have another cell that will give me my daily average of performance. For example today is the 2nd and I have performed this exercise 360 times, making my daily average 130 per day. If I performed 200 of the exercise tomorrow I would have a grand total of 560 repetitions making my daily average roughly 186 per day (the day, march 3 divided by the number of repetitions, 560) and so on and forth.
I need a formula that will automatically calculate that daily average as I progress with the month. But I want the calculation to stop at the end (i.e. I don't want it to continue as the year progresses, meaning the divisor keeps going throughout the rest of the year). Basically, I guess, I am looking to fill in the daily repetition and the divisor to increase each day as I do so. My average is to be displayed in cell B36, so today my formula should read (=2/B36) and on March 31st the formula would be (=31/B36).
I'm working on a time series dataset with a time step of 15 minutes. I need to calculate daily average of the several variables. So let column "A" be the "date-time" column, let column "B" be the "variable column" and column "C" be the "average column", I need a function that calculated in C1 cell the average of B1 to B95 cells, in C2 cell the average of B96 to B190 cells, in C3 cell the average of B191 to B285 etc.
View 3 Replies View RelatedI have a workbook with two sheets - DATA and SUMMARY.
DATA has two columns - date and data_value. Data will be added to this sheet on a regular basis
SUMMARY has two columns - month and average

I have a spreadsheet that contains developer related data. I want to be able to do a weekly analysis of average construction time and costs. The problem I am running into is properties enter rehab phase and exit rehab phase throughout the week.
For example:
I want to know the average $ spent and total rehab time week 1 of april. I may have 4 homes that entered rehab that week and 3 that move out of rehab that week. Moreover, I need to ensure those homes that entered and are still in rehab for that week are counted. How do I accomplish this feat?
I have a set of 7 years daily rainfall data. I need to calculate the daily average of rainfall from this 7 years data set. I don't wanted to calculate it by for example copying and pasting the first day rainfall of each year rainfall to a new sheet and average it for all the days. I need to calculate it all at a time.

View 3 Replies View RelatedI have two time series which span several years. The first series measures stock levels on every Friday (52 values a year). The second series measures the price level every weekday (260 values a year).
I'd like to condense the daily data in to a weekly average, can I do this easily? For example, I could manually use the Weeknum function to calculate the week number of each daily price data, then find the average daily price for each week, thus giving me 52 values which I can compare to the weekly stock series. Is there an automatic, fast way of doing this? Alternatively, I'd be happy to settle with a monthly average. Is this possible via macro's or does VBA need to be used?
I've set up a simple spreadsheet to keep track of my food expenses every month. The first column is for the date, the second is for the daily total expenses and then the next three columns are where I add the data which is then calculated into the daily total column.
I also have a total at the bottom for the entire month. Now what I want to do is I want to also have underneath the grand total, a cell which keeps track of my average daily expenses. Basically I want to divide the total expenses by the number of days which I've entered data. Now normally this would be fine but because I've applied the formula to all the cells in the expense column, it automatically lists every day as "0" rather than leaving it blank. So when it does the average calculation it's dividing my total by 30 days rather than by only the 7 days I have data for.
I need to monitor the average daily usage of a liquid tank for a customer. We fill this tank every few weeks. The formula I am looking for would ignore the fills and just count the daily usage.

View 5 Replies View RelatedIn a sheet showing 4 columns,a debit column,a credit column,a sold and a 4th column.I need in D3 a formula which calculates the balance of the first in first out balance,by diminishing the credits from the first debit and therefore to sold what remains from the 1st debit,once the first debit is settled ,then to sold the remaining from 2nd debit and so on,beside the formula in E3 I need a formula which returns the reference of the cell of which the remaining sold refers to.
I am ready to mail the sheet if possible.
example:
A2=100; A5=50; A7=10
B3= 20; B4= 50; B6= 40; B8=40
C2=A2; C3=C2+A3-B3; C4=C3+A4-B4; C5=C4+A5-B5; C6= C5+A6-B6; C7=C6+A7-B7
Results should be in D2=100; D3=80; D4=30; D5=30; D6=40; D7=40; D8=10
Let's say I have the numbers 1-10 in A1 to A10.
I want to create a formula in A1 to automatically add each number (1+2+....)without creating a new formula every time. I want to start this operation in B1.
Using the declining balance depreciation formula how can I have the individual time frame results put into to cells?
View 9 Replies View RelatedI need to locate/write a formula that can calculate the declining balance on revolving interest loans, such as a credit card. The formula needs to calculate the number of remaining monthly payments based on a stated interest rate and payment amount (i.e., present balance $2000, annual interest rate 18.99%, payment $60 per month). And then, if possible, the formula also needs to translate the answer into a definite Month and Year going forward from today's date (or calculated in another cell of the worksheet for display).
In essence the formula would begin as
(2000 + (2000 * (.1899/365)) * 30) - 60 =
then repeat the calculation using the answer above, and so on, until the original principal amount had declined to $0, and finally count the number of months it do to get there. This is essentially a mortgage type of calculation.
I know I could write the formula repeatdly one month at a time across a few hundred/thousand cells, but there must be a more economical way to do so.
I want it to average based on month and year. I have daily data and want to average everything for say January 2000 into one cell and February of 2000 and so on. Column A has date (mm/dd/yy) and column B has data.
View 13 Replies View RelatedI have the following scenario:
Cell A1 shows a specific value (pivot table value), but same A1 cell value might change if pivot table is refreshed.
So I am trying to automatically copy A1 value to another cell but I need to keep track of each value when pivot table is refreshed.
I have been researching about =Value formula, but it does not work properly since A1 cell reference will change each time pivot table is refreshed.
I have a table which contains Day, Projects, Proj Completed and % completed. I would need to get the target % starting thu so that I can end the week completing 90% of all my projects. Fri - Sun would show the same targets as Thu. Once Fri comes, i just need to update Thu with the actual projects I completed and Fri - Sun will show me my new target % to achieve 90%. Just in case hitting 100% will not achieve the 90%, it will just show 100% for the remaining days.

Im trying to come up with a password that changes daily that contains 2 constant numbers and some multiplication:
The formual would need to be like a string for example:
1 (the day * a number) 2 (the month * a number)
The numbers 1 and 2 are always the same.
I have a spreadsheet that has the month (number) in one cell.
The days are in columns A1 - A31
Everytime i try to do this in Excel, it trys to multiply every number.
What I am trying to do is to create a formula for the attached spreadsheet - that calculates the daily compounding interest based on the higher rate of the two rates for the first five years then after 5 years the calculation should only be based solely on the blocked rate.
View 5 Replies View RelatedI have create an excel formula that I need to input data daily.
Every day, I need to insert a line and input my new data.
Below is my formula
=IF(V159="Skip","Go",IF(P160>0,IF(COUNTIF(C60:D154,">"&H159+3),"Good"),IF(COUNTIF(C60:D154,"<"&H159-3),"Good")))
The problem is that when I insert a line. Most of my variable will change according except C60:D154
As you can see below
V159 change to V160 = This is good
C60:D154 do not change accordingly. How can I make it change accordingly ?? Why it is not changing when I insert a line ?
=IF(V160="Skip","Go",IF(P161>0,IF(COUNTIF(C60:D154,">"&H160+3),"Good"),IF(COUNTIF(C60:D154,"<"&H160-3),"Good")))
I'm using the formula =AVERAGE(B16:L16) to give me the average.
However I have a couple of problems with this. Firstly I would like to exclude the value zero from the average. Secondly to also ignore the lowest and highest values.
Example, if the values in the cells are 0,1,2,3,4,5,6,7,8,9,10 then the current result shows 5, by ignoring the 0 and lowest value 1 and highest value 10 the average should be 4.5.
I have a running balance that works beautifully in my spreadsheet, but I cannot get it to display my balance on a line above my spreadsheet. I have attached a copy of my spreadsheet to make understanding my question easier. I have a sell price that will remain the same and as the bill is paid the balance should work itself down to $0. Currently I have three deductions in my spreadsheet but the balance only shows the first deduction.
