I have a contract start date. The payment is due every seven days. I have entered the start date. i need the "next due date" to automatically calculate in the "due date column". here is my problem if a customer has a due date say on 2/15/2014 his next due date should be 2/22/2014. regardless if he pays on the 14th or 21st. i need this date to change each time a payment is made.

I am trying to get the formula for calculating yearly rental imcome. The range is 10 years and the interest is 34%. The first year payment is 42,000 and the 10th year payment is 56,000. I can't figure out how to do the other years. The principal is 325,000 and the sale value is 425,000.

I just started a boat rental business and I would like to create a booking sheet for a small fleet of boats. Some of the boats can be rented on half hourly basis and for longer periods (in hours only not days).

I would like to have a sheet to maintain a booking system and to calculate the total income per day as well as keeping the basic information of the booking clients (names, numbers etc..).

(I hope the ... is okay, couldn't figure out how to make the columns line up.)

I can use Sheet Two for the next part, but I don't know how to to get a total time per month for each seperate jeep. Most of the time, there will only be one record per month per jeep, like the second line above. But lines one and three are for the same jeep, and so I need the formula to add column E up only for those two lines.

I am trying to track installation of equipment in excel, I know what I want done, but not how to do it. I have 8 columns, and I want a yes in each column to equal 12.5% and a column to show progress at the end, I also want to show total progress for installation of all equipment at the bottom of the page

I have a list of equipment and want to select from three criteria to obtain the result; indoor1, Type and Power (all drop down) I have used index and match to get results in various cells but can't get a correct result for Outdoor and Indoor2, Indoor3, and Indoor4 (all coloured red).

I have difficulty to generate sheets on the Status of Equipment from the master sheet. I need to manage the maintenance and diagnostics of a plant, and I have a whole list of equipment, thus when any of those goes faulty, I want to enter the word "Fault" in Column G, Then It must automatically generate the Template for that tag, and name the sheet same as the Tag.

I have added an Attachment : Template for MnD_ExpertQ.xlsxâ€Ž

I have a table with average temperatures(120,125,130...220) on the vertical axis and equipment sizes across the horizontal access (size 1,2,3...11). At the intersections is the amount of heat given off the equipment. This table is used as a reference for another sheet in the same workbook.

Basically what the sheet is for is to look up the average temperature of a piece of equipment (given the size and exact heat given off). In order to do this, I need to interpolate using the 2 closest energy values and their associated temperatures. There's a better explanation in the file and it makes for sense when you're looking at it. Attached is the table.

I have been using Excel to create equipment lists for my work. The forum has helped me by creating a visual basic macro to create a 'final list' sheet compiled from the other source worksheets.

On my 'final list' sheet I need the first 10 rows to be left out of the macro’s so that I can add header information like job reference etc. I have tried altering the visual basic code by adjusting the row numbers in it so that it starts at row 10 but this keep's on producing error codes. This is due to my limited knowledege of what each line does.

I also wish to be able to paste new equipment into the final list sheet. When I do this at the moment the code does not recognise it is there and does not carry the information accross back into the source sheet. It is the same when I block select an area and delete the code does not recognise I have done this which is fustrating.

I work for a equipment hire company, where various computers and structure are hired out on different jobs. We are getting to a point where keeping track of stock is a problem, we need to quickly be able to check if an item is already booked on an upcoming job, and keep track of home many are in stock. ETC.

Macro to find data from a huge database of items of equipment and find certain ones relevant to an area. I am using Excel 2003.

I have a spreadsheet which has three tabs.

Tab one has a list of equipment with a Ref (Col A), ID (Col B), mile (Col C) and chain (Col D) start and a mile (Col E) and chain (Col F) finish.

There are about 25 different Refs and IDs, but all rows have different Mile and Chains.

The second tab is an identical template of the third tab which is where I want the results to go (see below)

The third tab is raw data which list thousands of items but I want the macro to find the items which are in the first tab using the ref, ID, mile and chain information.

how to calculate the age from the date of birth and was given these two responses

1) I may be way off here but all that coding seems a waste !

I have in cell A1 = BLANK <--- enter your DOB here

I have in cell A2 =NOW()

in cell A3 do = A2-A1

Format that to General

In Cell A4 do =A3/365

Format that to no deciamal places and you get the age - this one is adding a year to everyones age?

2) Alternatively, if the DOB is A1 :-

=INT(YEARFRAC(A1,TODAY(),1)) - This one does not work it is saying there is an error with the "yearfrac"?

It is also when I am trying to put these into a pivot table, the pivot table is listing these down to 5 decimal places( when I have formatted to zero)????

I have a list of several hundred loan recipients who are all starting to pay their loans back on different dates. I am able to get the calculation to work so that I just need to put in the start date and excel works out the other 5 or 6 payment dates.The problem is, some people pay back on the 29th, 30th of the month which is giving me a headache when they are supposed to pay in February. The formula I am using calculates the next date of payment to be on the 3rd March (skipping the February payment all together).

The formula I am using is : =DATE(YEAR(A10),MONTH(A10)+1,DAY(A10))

I am trying to create a formula that returns the date on the friday (ie last working day) of whatever week I am currently in. So, for example, I guess I would use the 'TODAY' or 'NOW' function somewhere to determine the present date - but how do I then determine the date on the Friday of the current week?

I was trying to figure out how you could caluculate a project end date, based on a start date (dd,mmm,yyyy) and a project duration of lets say 5 work day and the work week is five days long (monday to friday). If i have a leave on the week days like tuesday is bank holiday then it should give be the date excluding that tuesday and wednesday leave and caluculate 5 working days and shoule give the project end date.

Example date: 5-Oct-09

Project end date:09-Oct-09

If i have bank leave on 06-Oct-09 means.

My project end date:12-Oct-09

Note:Bank holidays are fixed date example(every year bank holiday 06-oct-09,02-Dec-09,25-Dec-09)

I have dates listed in column A indicating the day an action was performed. In column B I need to have the date in column A changed to a Friday. If the date in column A is not a Friday, then the date in column B needs to fall back to the previous Friday. For example, if the date entered in column A is today, Monday August 7, then the date in column B that I would be Friday August 4. Can anyone think of code that determine this and place the value in column B? Currently I use vlookup to go to another sheet where all the possible dates are listed with their respective Fridays, but this slows down the calculation worksheet as the file is quite large.

I have a truck log. Every time some comes in to take a truck they must log the truck out with the millage. After a week, I am supposed to find out how many miles my trucks ran for that week. What would be the code to....

In K column, calculate the milage that is in row F; which is A3 - A2 and so on down. But it would have to skip a line every time the truck number changes (in column C) it would skip that line. It would go until a blank cell.

Within 4 columns, I have a series of: Start Dates / Start Times / End Dates / End Times I need to create a formula which will give me the sum total of the difference between the data sets.

For example, the time difference between 8am on the 20th March and 1pm on the 21st March is 29 hours OR 1 day and 5 hours. I need a formula which will calculate this for me.

I am trying to calculate dates that will happen 16 days from date specified in column A (A23:A200), based off a certain entry in Column B (B23:B200), which is named in cell P5. I can get the date by doing the specified date + 16, e.g. =IF($B$23:$B$200=$P$5,$A23+16,"")

The trouble I am running into is not having the date populate until it has reached 16 days from the dates in column A, show blank if possible until 16 days from date in column A. The dates in column A will always be previous to todays date.

I am trining to calculate SLA times based on P2, P3 & P4 calls, the only issue is with P2's as the SLA includes the weekend, how to include the weekends into my formula?

AE2 = Priority U2 = START DATE & TIME V2 = END DATE & TIME

I've managed to sort the first half of this issue, in that I can calculate the number of days within a given month which fall inside specified to and from date parameters..

This examines a date value (A13 in this case) and assess whether any days within that month are between the two date parameters specified in H9 and I9.

H9 = 01/01/2011 I9 = 15/05/2011 Jan-11 31

[Code]....

What I need to do now is specify a second set of date parameters in H10 and I10 and add those into the assessment. The dates will NOT overlap.

So, for example, if I were to set H10 as 01/07/2011 and I10 as 15/07/2011, the results would appear as below

I want to find the hours worked in day shift and night shift. Day shift is from 06:30 to 18:30 and night shift is from 18:30 to 06:30. Listed below is an example of my date/times.

Note that the night shift carries over to the next day.

I'm having trouble with a complex Excel formula. I'm calculating child support owed based on the current date coupled with future child support owed. My columns are as follows:

On the first of each new month, the Future Amount Owed should decrease by 508. Altering the Total Amount Paid should decrease the Debt column. Progressing another month without altering the Total Amount Paid column should add 508 to the Debt column while subtracting 508 from the Future Amount Owed column.
