Calculate Balance To Zero Based On Constant Fix Rate & Withdrawals
Feb 5, 2008
I have a situation where I have to determine the required size of a deposit from which constant withdrawals are to be made until the deposit runs out to ZERO. The deposit earns interest at a fized rate, capitalized monthly after each withdrawal had been made.
In my example case, the target month (The actual cell that needs to have a value of ZERO (when the deposit runs out), or the "Range") is found in cell G16. In another situation, it may be found in cell G19 etc, depending on the situation.
It is this changing of the target cell (the one that needs to be ZERO) that has me stumped. I've been thinking of using VLOOKUP (not trying to lead you ;-)) to determine the actual position of the cell that need to have a value of zero but do not know how to build this into the VBA code of Goalseek. This target cell in the Goalseek code should be the cell in column G opposite the figure 1 in column A.
In my example I simply typed in a figure 1 in column A - in the actual spreadsheet the position of this figure is calculated with a formula and its position moves from situation to situation. If the 1 is in cell A19, the target cell, whose value should be ZERO, will then be cell G19..............

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 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?
A B C

I have 3 sets of data for two different groups:
Group 1 - Inbound
- Total volume
- Gross adds
- Win rate (gross adds/total volume)
Group 2 - Outbound
- Total volume
- Gross adds
- Win rate (gross adds/total volume)
I need to calculate the weighted average of the win rate based on volume of calls. Is there any way to do that?

I am looking to setup a formula to calculate a Fee that is based on the number of users of a service in a month, with the rate varying by the number of users. The first million users in a month will bring in $0.40 per user, for users 1-4M it will bring in $0.30 per user, for users 4M-7M it will bring in .20 per user, and for users beyond 7 million it will be .10 per user. So for example, if a user count was 9 million in a month, the calculation would be ($0.40 x 1 million) + ($0.30 x 3 million) + ($0.20 x 3 million) + ($0.10 x 2 million). I know the answer to the problem is obviously $2,100,000 but I can't build the formula that solves that and can handle instances where the user count is capped in one of the individual brackets. (IE if there are 3.5M users)
I've attached an example spreadsheet : Variable Fee Schedule.xlsx‎

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.
writing a formula to evaluate over 360 periods.

Some years ago I came across a formulae to calculate Daily Interest on a Building Society Savings account in the UK. I have used this since but find my calculations never work out the same as my BS, although to my advantage! It is =B3*B4/360*DAYS360(B5,B6,TRUE) Where:
B3=Capital
B4=Interest Rate
B5=Starting Date
B6=Finishing Date
For some reason the formulae uses 360/year and not 365/year. Using both still gives wrong answer.

I am trying to calculate a new base pay rate, but I need it make sure it is at least brought up the new minimum and capped at the new max of the range where applicable. The increase is based on 10%
So here are the columns used:
L = Current Base Pay
Q = New Min of the range
S = New Max of the range
U = where I want to calculate a 10% increase of L, but ensuring it is brought up to at least the min (Q) or not over Max (S). In other words if my min is $12 and Max $18 and my new base pay is $16 -- then I am good. However it if is $11.50 I need the formula to return at least $12. And visa versa -- if the new rate would be $18.50, I need it to return no more than $18.

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.

I am looking to reassess the useful life of existing fixed assets by one/two years.
For example:-
Original cost $1,727.00
Start Date 30/12/2008
Current End of life 29/12/2013
New End of Life date 29/12/2014
5 year - 20%
NBV as at 30/06/2013 $174.12
How can I calculate the new rate, as I can not change the prior financial years depreciation. I am looking for a calculation, to test the assumptions, and see the overall change. This is just one example.

I have a workbook with rental properties containing 2 sheets. 1 sheet with the general details and the rate sets and 1 sheet where I'm trying to calculate the total price for a period of time between 2 dates. I would like the people who use this workbook to simply enter the dates and get a price based on the amount of days within a rate set.
eg: 1 to 7 days is weekly, 8 to 31 is monthly etc. To display this, I'm using: =LOOKUP(H3,{0,7,30,180,365;"daily","weekly","monthly","6 months","yearly"})
These rates are different for each property, and this formula isn't exactly dynamic; it just displays which rate should be used.
Now my idea is to use IF/THEN kind of a formula, but I'm lost on how to do this. The actual rates are on the other sheet in separate rows and columns belonging to the appropriate property. Also, the rates as they are will probably need to be recalculated to a daily number before it can be used for the price calculation, because a month has either 29, 30 or 31 days.
At the moment the daily rate is diplayed as a daily rate
The weekly as a weekly rate
The Monthly as a monthly rate
The 6-Monthly as a Monthly rate (with a minimum of 6 months of course)
And the yearly also as a Monthly rate (with a minimum of 12 Months)
I've attached the sheet as a reference : Property details import.xlsm‎

What I need is a worksheet which will generate fields from a set of variables (similar to a loan amortization schedule).
I don't know how to write the field code to include the annual percentage rate increase based on that additional input variable.
Input variables would be:
starting rate: (ex: 8¢/kilowatt hour)
starting date: (ex: July 2013)
average kw hours/month: (ex: 1062.5 kw hours)
annual rate increase: (ex: 3% *default 0%)
years to display: (ex: 25 years, *shown in months in fields below)
service months per year: (ex: 12 *default 12)
[code].....
So, data fields below the variables would be blank until these are entered.
Assume I would protect the sheet to avoid messing it up.
this would generate a chart showing rates over time from the fields below.
Also it would generate fields in a summary area to show the rate per year for future years.
Secondary, if there were a way to input actual usage and rates from specific months in the past, that would be useful but not part of this forecast model.
The goal of this model is to forecast electrical costs for residential power users compared to independent solar power generation to 25 years forward.
I want to make this because I am skeptical of the advertised savings that solar installers use to convince clients that their return on investment is so high. I believe their data to be greatly inflated projections.
Using this in comparison with other data such as inflation and wages will allow me to get a very good economic picture of the future of independent solar energy generation and its impact on the average home owner.

The way I have this sheet setup is to calculate a 20% fee off the interest earned column "D". Say you earned 6.5% on a beginning balance so the interest earned is in col "D". This works fine for a 20% fee but I need the fee to calculate a 10% fee if the interest in column "C" hit 4% or below and it also needs to be able to calculate a 20% fee if the interested earned is above 4%.

Our office has a vacation days accrual policy based on number of years worked. We have a vacation days number, based on year of employment, the employee earns monthly. I need help with a worksheet, formulas, to document each employee, the year of employment they're in, # of days they have available based on the current month (which would need to add up automatically as the year progresses), then any days they request off, and finally a remaining balance of days left.

I have a userForm (Form1) that contains a persons name that I would like to reference in a separate UserForm (Form2). In the separate UserForm (Form2) I need to reference this persons name many times, so I was wondering if there was a was to declare this name in the separate UserForm (Form2) as a constant. Only thing is that a constant, to the best of my knowledge, must be an expression and not a variable. Mainly, I'm trying to avoid declaring the myName variable in each Sub within Form2, which it will be needed for a ton of Sub's.
Code for Form2: Const myName As String = Form1.txtName.Value

I have a list of data which which has repeated supplier numbers in column A. For instance
A123
A123
A123
X456
x456
x456
x456
The information in other 13 columns is variable and I need to be able to move all the rows which start with the first supplier number to another sheet which I will rename to that name, then move the second set of supplier numbers to a second sheet etc. So in my above mini example I would have one sheet named A123 with 3 rows of data and another sheet named X456 with 4 rows of data.
The number of supplier codes will be different every day and the number of rows within each supplier number will also vary. Each new datafile that comes in daily creates a new file do I do not have to worry about existing values only what the current file contains. I have used the following code to move data based on a known constant before but dont know how to tell the macro "move all the data while the value stays the same"
Sub DiffOrderNo()
Dim totalrows As Long, row As Long
Cells.Sort Key1:=Range("A1")
totalrows = ActiveSheet.UsedRange.Rows.Count

I am trying to apply a multiplication factor that would vary depending on the sum of a particular cell. For example let's say the value of cell A5 is the SUM of A1:A4. Let's say the value is 255,000,000. my multiplication factor table looks like this:
1 - 50,000,000.........................(0.17)/1000
50,000,001 – 100,000,000..........(0.13)/1000
100,000,001 – 250,000,000.........(0.10)/1000
250,000,001 – 500,000,000.........(0.08)/1000
500,000,001 – 750,000,000.........(0.07)/1000
750,000,000 ++ .......................(0.05)/1000
So depending on the range the cell sum falls into I need the formula to apply the appropriate multiplication factor and divide by 1000. I'm trying to avoid manually inputting the (0.XX)/1000 based on the formula identifying which range the sum falls into and automatically applying the appropriate multiplication factor. In the example above the formula would be applied to the A6 cell and identify the A5 sum as falling into the 250,000,001 - 500,000,000 "range" and automatically apply the corresponding multiplication factor.

The formula I am looking for would tell me what annual growth rate % I would need to achieve to make any investment reach a set target, for instance, what % of fixed annual growth would I need to make 200K grow to 750k in say 10 yrs or any time scale. I was given the formula below but Excel tells me it's wrong, I have tried putting 10 before ^ and the 10 after but to no avail, could some kind soul please put me straight.
r = 100((Y/X)^(1/n))-1)
So for X = 200, Y = 750, n = 10, we have
r = 100((750/200)^(0.1))-1) = 14.1309%

I am looking for a formula which will compute interest earned (not ending account balance) for the following scenario:
1) Set $ amount (say 19250) is deposited on January 1.
2) Annual interest rate is .95%
3) Interest is compounded daily
4) Fixed withdrawals of $1750 are taken each and every month on the first day of each month
What is the total interest earned on the account? Basically, it is a issue where each month diminishes the "pool" of money earning interest. I get what's going on conceptually, but can't figure out which Excel function to use.
