Multiple Loan Repayment Optimization
Apr 19, 2006
I have 4 Loans of various interest rates, balances, and minimum payments.
Assuming I have a certain amount of money to pay out each month, how can I minimize the total amount I pay over the lifetime of the loans?
Given:
Total Monthly payment: M
Interest Rate for each loan: R1, R2, R3, R4
Initial Principal for each Loan: P1, P2, P3, P4
Minimum Monthly Payment: Min1, Min2, Min3, Min4
Each month, how should I distribute M over the 4 loans?

In a financial environment we have a calculator which uses iteration to allow for a cost being added to loan amount where the cost is based on the total loan amount. Iteration is set to 100 iterations with max change .001
On one PC the first time the calculator is opened it gives a particular (incorrect) result. If the input cells are cleared and the data re-entered, it gives the correct result. This only happens on one particular PC. Is there some other setting , other than the iteration setting, that would cause this?

I have the following rows in my excel sheet:
-Cash needed to start the quarter.
-Net cash position.
-Begining of the quarter debt owed.
-Internal repayment.
I am trying to develop a formula for internal repayment which must fulfill following requirements(Net cash position-cash needed to start the quarter),the remaining amount goes to internal repayment but that must be <=Begining of the quarter debt owed.

Optimize the code below to perform a search function for two variables. Right now it takes a while to execute as it goes through each cell row by row, column by column. It would be nice to optimize it to function a little faster (make that alot faster) . I realize my coding methods are not all best practice habits, so let me know your thoughts, workarounds or adjustments.
In its basic form the code pasted in below is being used to locate data at the intersection of a given row and column. And this data can lie anywhere within this array, unsorted.
Where the Row to search contains a team members name (Derek, John, etc.) D3:D50 and dates in columns Q3 to IU94.
My spreadsheet has a data page with a list of team member names in D3 to D50, and a listing of dates running accross Q3 to IU94. Each members name may appear muliple times through out D3:D50.
So for instance "Derek" (cell D6) worked 40 hours (cell Q6) the week of 9/1/08, it is the 40 that I want returned to a summary page and since the name Derek may show up more than once down the list I want to return all occurances where a date and name instersect on my summary sheet.
[/quote]
Below is my code which is currently used to lookup team member name "Lookup_Value1" for a given date "Lookup_Value2), it indexes the date column to search for data.
Function LOOKUP2(Lookup_Value1 As Variant, Lookup_Value2 As Variant, TABLE_ARRAY As Range)
Dim nRow As Long
Dim nCol As Long
nRow = 0
nCol = 0
With TABLE_ARRAY..............

Can anyone recommend a good source for tips on optimizing VBA code? I'm working on
an application that reads and interprets large text files (3500 lines) and starting to think
about the efficiency of the code inside my read loop.
For example I'm wondering how Excel actually implements access to cells internally. Is a
cell just a variable or part of an array?
If I do something like: range("A1").value = range("A1").value + 1 inside a loop is there a
performance penalty compared with saying: count = count + 1 and then writing this to a
cell outside the loop, eg: range("A1").value = count ?

I use a lot the function “Find” in Excel but the problem is that it takes a lot of time, so I’m searching for another function or code that can be faster than that, the Worksheets that I use in Excel contain thousands of sheets so it takes hours to execute the Macro.

Have an optimization question for you. I'm starting to try to optimize my macros and I've heard/read it's best to not activate or select anything. - I assumed that meant it would be more efficient to run code without it.
I have a loop I run through about 600 times that takes .75 to .85 seconds to run through with the following piece:

Let me first quickly describe the workbook setup. I have a main workbook ("Fees") that acts as a master list for every employee's clients' account numbers. Every month, 30+ workbooks get downloaded from 3rd parties that have the client account numbers, as well as their current account value.
My macro- Loops through every employee's worksheet within the Fees workbook, and loops through every account number. It then compares the account to every account in every other open workbook. Upon a match, it pulls the account value back into the main workbook. After it finishes looping the Fees workbook, it starts to loop every open workbook, and checks every account value against every account in the Fees workbook. If it doesn't find a match, it prints the value on a Missed worksheet within the Fees workbook.
The situation- I know for a fact this a verrry slow way to go about what I need to accomplish. I am very new to writing code, and gladly can take the extra minutes to let the code execute to know 100% nothing was missed. Going forward, I would like to start trimming execution time without jeopardizing the 100% accuracy of my slow macro.
The question- Based on how I execute my loops, what is likely to trim the most time for the range lookups? I have no practical experience with Vlookup, but I understand that is a possibility I should look into. I'm vaguely familiar with Match, and arrays, and I believe they could also trim time. I also realize there are probably at least 15 other ways to go about it I am not even aware of.

I'm working with a loan amortization worksheet (downloaded from Office Online). Unless I don't understand correctly, the date formula on the worksheet doesn't calculate the way I need it to. I'm not totally sure what the formula they use is doing. It does use a lot of named ranges.
If a user inserts the total "Number of Payments per year", then I want the date to return the proper payment date.
For instance, If the start date is 1/1/07 and the number of payments per year is 24 then the payment dates should be like
1/15/07
1/31/01
2/15/07
2/28/07
It should be the 15th and the last day of the month.
If I put 52 as the number of payments then I want the formula to set the payment dates to every Friday.
I'm still learning formulas so bare with me guys. Attached is the worksheet.

I have used the PMT function but this gives me the total to pay per month.
I want to know what the repayments would be and also allow me to add in each one of the periods and extra repayment option.
So if in the year I wanted to pay an extra $100 per month, I would put $100 next to each period as in a particular period(s) I might not have to put in there but want to predict what the amount owing on the house is.
Is this possible or is this too complicated.

There are various references and links to " mortgage calculators;" though they are specific to the US dollar. Is the formula still the same, irrespective of the currency and why does it come across as quite a complex calculation? i have been taksed with designing a "calculator" and don't seem to know where to start as the currency issue is confusing me.

I currently use goal seek to calculate an interest rate for a loan product. My problem is i would like to have the same function but not through a goal seek. In goal seek i have to set the value i want to achieve but ideally i want it to calculate automatically
I have attached a workbook with details. I use a loan amortization schedule to calculate the interest from parameters set on sheet 1

I have a calculation I do that calculates a clients "effective interest rate" if they make extra payments towards principal.. Calculation works fine.. However, I am now trying to figure out how to amend that code if it's an interest only loan, anyone have any ideas?
Here is the effective rate calcs on a random normal amortization loan:
this is in B2, and answer is 7%
=RATE(B4*B5,-((B3+B7)/B6),B7)*12
B3 = Total*Interest 279017.8
B4 = #*Years*in*Loan 30
B5 = #*Payments*/*Year 12
B6 = Total*Payments 360
B7 = Beginning*Principal 200000
B8 - Ending*Balance 0
problem is when someone is on an interest only loan they pay more interest than a normal amortization because they are not reducing the principal in the first x number of years. So I need to compare the interest only effective rate to an interest only loan.
Here is the example I'm working on... A client's loan is the following:
Loan amount - 131,538
interest rate - 6.15
30 year amortization
10 years interest only
normal client would pay an interest only payment of 674.13, then after i/o period would go to 953.80 for last 20 years of the loan, and they'd pay about $178k in interest.. Now if that client pays an extra 1,000 per year, I can calculate the amount of interest they'd accrue, but have no clue how to back into the "effective interest rate", basically that says you are paying the same amount of interest as someone with a x.xx% interest only loan.

I am running Win XP and Excel 2003.
I have a macro I found here on the boards written by Lenze to delete an entire row based on what is found in column A. I would like to delete any row where Col. B contains 10 or less characters and I have modified it to do so (or at least I think it does). My problem is that it takes about 12 minutes to run the macro (I have about 50k lines to run through). I was wondering if this is the fastest method or if it examines things other than just column B.
Sub Test()
Dim i As Long
LR = Cells(Rows.Count, "B").End(xlUp).Row
For i = LR To 2 Step -1
If Len(Cells(i, "B")) < 11 Then Cells(i, "B").EntireRow.Delete
Next i
End Sub
After this runs, I am left with Columns A to somewhere around AH. The columns are generally in the format of text followed by a numeric column. An individual text column has the same name through all of the rows. The numeric columns have varied values whether negative or positive.
Ideally what I would like: If a given cell (ie. C2) in Row 2 is numeric, then copy the cell to the left (ie. B2) into (ie. C1) and then delete Column B. I need this to work for multiple columns from B to C, skip D and E, and then from F to AG (and maybe beyond).

I have been loaning my brother money over the past 14 months. The loans have been in the form or $1000 per month plus random payments for one-off expenses like doctors fees. He's not paid anything back yet but we want to know what the total owed is for interest of 10% per annum.
I can easily create a table with payments I've made and the dates with a running total of how much I've paid but how to I create a running balance of what he owes over time based on adding in interest. This might end with a one-off payment in a couple of months, I'd like to calculate what is owed there as a minimum.

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?!

I have a created a Data Chart Below. A - C are the columns and 1-7 are the rows. I have hard-coded the equation in cell B5 that I am using.
What I want to do is input an number into B3 that automatically makes Cell B5 equal to Cell C1. Is there a process in excel you can use to do this. Or do you just have to use trial and error?

I have uploaded a sample amortization schedule.
1. I require the table to adjust itself based on the loan period and number of payments per year entered in D14 and D15 respectively.
2. Also, if a value is entered in column E, then i require the whole table to update as well.

Trying to automate the period part of the impt function
To calculate current value of loan i have the below formula below with the 3 being the current period
=IPMT(4.3%/12,3,5*12,-7000)/(4.3%/12)
What i would like to do is for the period to be self calcuating from current date and the loan start date. I can return a value in days using start date - today() and aware month function returns the month number but stuggling to find a way to work out cumulative month from the start date.

I'm developing a loan processing system for members of a club. When an applicant asks for a loan, the club will calculate 10 % of that interest and the applicant will have to pay it back in 5 successive fortnightly instalments. If he asks for a loan in the first fortnight (1), for example, he will have to start paying instalments in fortnights 2,3,4,5,6 to pay it all back.
The system currently has 4 worksheets. The first sheet is a the loan application form. The cells outlined in thicker border, are the cells in which details must be input. Once it is input, the data will be automatically placed in the Processing worksheet using IF and VLookup functions (See spreadsheet attached), which is used as a basis for the loan schedule Worksheet. What I need is a macro that will copy the range filled in the Processing worksheet, and copy it to the exact same location in the Loan schedule worksheet (The cells with the same fortnight columns and the same member name. This is how the loans are to be filed.

I'm currently doing a survey using an excel workbook that contains multiple questions across multiple worksheets using radio buttons linked to certain cells.
I have around 400 workbooks coming back to me, so what i want to do is take specific values from across many worksheets within each workbook and combine them into a large master table in a seperate workbook.
I've tried using VBA, but not being very proficient at it i've hit a brick wall with that, so i'm hoping that there is an easier way to do it than what i'm currently pursuing.

I've got data being scraped from a site, putting 1 new workbook in a folder each day
each workbook has 40 sheets in it.
i need to run 5 modules in sequence on a sheet then loop to the next sheet and run the same 5 modules.
ive writen all the modules, and can loop them through the sheets in sequence but i cant work out how to loop them through the each workbook in the folder..
is there an easy way to do this or can it not be done because it would need access to the folder that holds all the wordbooks which lives outside of excel on the desktop ?

I maintain the data flow at my work. We send and receive the data using excel files with specific formatting that I then upload to the database. Each time I send or receive the excel file I must log them, this is what my code question refers to.
I use RDBMerge to merge all the contents of the 100 plus excel files into one worksheet. The first part of the macro cleans up the merge data for use in the log (i have attached an example of the clean data and finished log).
The blue shaded area of the "Raw_Data" is what the clean data looks like, the yellow column is what current macro records for each record.
As you can see by the example the Raw_Data is only two files LL_LLL_BOB_ToLLLLL_20121228_01 & LL_LLL_BOB_ToLLLLL_20121230_01, each with more that one record.
The log code in column "H" Is based on this criteria:
First Letter of the Unique ID in column "E" - O, M, or L
Program Type in Column "F" - U or R
1. O-U = U
2. O-R = RU
3. M-U = U2
4. M-R = R2U
5. L-R = R
You will note that Columns G-R of the "Log Sheet" correspond to the "Record Type" found in Column "G" of the "Raw_Data" sheet.
This is the area where my skill at using scripting dictionaries fails.
The results for the log list each file only once, but the log code for each corresponding "Record Type" in columns G-R of the "Log Sheet" must contain each unique instance of the code. In other words
if LL_LLL_BOB_ToLLLLL_20121228_01 contains an O-U with an "A" Record Type and an M-R with an "A" Record Type; then, on the log sheet there needs to be the codes "U/R2U" in the cell intersection of the LL_LLL_BOB_ToLLLLL_20121228_01 record row and "A" column (which is column "G")
So, If the File contains one of each code for each Record Type the corresponding cell must house one of each code separated by a "/" without any spaces. This means the cell value could no code, or one code and all the variations in between to all five codes. Also, for ease of human reading the log codes should be concatenated in the 1-5 order that I listed them in (U/RU/U2/R2U/R)
Here is my code so far.
VB:
Option Explicit
Sub test()
Dim dic As Object, a, i As Long, rng As Range, e, w, n As Long
Set dic = CreateObject("Scripting.Dictionary")
[Code].....
