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.
From a chart in Excel I need to automatically calculate what the annual percentage growth rate is of a trend line. How to automate this in Excel? I've attached a sample so you can see what I'm trying to accomplish.
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.
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.
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,
I am trying to calculate APR (Annual Percentage Rate) for a mortgage loan that has a balloon feature. I have tried to the the RATE function but it only gives me the APR for a loan that is ammortized over 30 yrs and paid in 30 years. I need the APR for a loan that is ammortized for 30 years with a baloon in 5 years.
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.
I've got a spreadsheet where the start date is amendable and this is what I wanted. E.g. start date is Jun-14 and I want the formula to to calculate annual salary divided by 12 in each month from June onwards until Mar-15 (Financial year is April to Mar) and the same way to not show anything in April or May as they started in June... How can i achieve this please as I tried IF statements and it doesn't recognise dates and years...
I am trying to figure a formula that will give me a monthly increase with a annual target. Example:
2006 sales were $100,000 and December 2006 sales were $9,000.
For 2007 I would like a 10% increase in sales which means I should end up with $110,000 at the end of 2007.
The formula should figure a gradual sales increase each month until December 2007. I am assuming the business sales trend is upward with no seasonality so that January 2007 should be the annualized increase over December 2006. . I have used the formula =100000*((1+.1)^(1/12)-1) which works for 2007, but it gives me a large jump between December 2006 and January 2007 and then a slight increases each month.
I am trying to calculate the compound annual growth and my starting point is a negative number. The example is that I have (273,000) for the YE 2003 and have Growth to the amount of +767,000 at YE 2006. The formula I have been using for other calculations where the starting point is positive is =POWER(J23/C23,1/O$1)-1. Where J23 = a positive amount and C23 = a positive number. This formula works fine, but when C23 = a negative number the formula does not work and the % does not make sense.
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 have US money supply data, arranged monthly from 1975-2008. I need to calculate the monthly growth rates. I would really appreciate some help as I have no clue how to do this.
here is a link to a text version of the data I am using: [url]
I'm doing an exercise for school and I'm totally confused here. I have to:
With the original assumptions, goal seek to determine what the Annual Rate Increase would be for the total expenses to be $175,000 (answer = 20.77%). Here's what I have: through the process?
If I invested $350 per hectare into a project and at the end of 12 years that investment yielded me $150,000, what would my rate of return be over the life of the project?
How can I get the median of a column that contains both hourly and annual rates? I would like to either multiply the hourly rate * 2080 or divide the annual rate by 2080 then get the median.
I have been trying to compile some monthly and annual data from our main sheet to a FY09 sheet (for the fiscal year 2009). The 2 tabs in the uploaded example are the Distribution tab which we use to track the status of every item and the FY09 tab where I need the totals to be calculated for each month as well as the entire year. I have tried several formulas I found while searching the forum but I can not seem to get any of them to work, (I am sure it is because I don't understand them very well).
Since any formulas used will need to be copied 200 or so times, I would really like a VB solution which should also reduce the physical size of the file. I also tried a pivot table but I do not think it will show everything I need.
Basically, I need all the items separated by month on the FY09 tab. Then column 'F' on the Distribution tab needs to be summed up for each item in column 'D' of the FY09 tab for the respective month and multiplied by the respective item price in column'C' with the total value going in column 'E'. Column 'D' and 'E' need to be summed up for each month and cumulative for the entire year. There needs to be an average items and value for each month as well as for the year.
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.
I have downloaded .csv files with my phone call costs. I want to compare phone companies, so I need to calculate the h:mm:ss amounts to $ based on flagfall and rate per 30 seconds. I can open the .csv files in Excel but I do not know anything about Excel.
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 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.
I have a list of dates with respective balances. I am wondering how to get Excel to determine if the end of the month has passed after a certain date and then calculate the return for that month. What is the most efficient way in your opinion?
I want to calculate the subscription rate as follows:- Subscription is fixed at the minimum rate of Rs.200 and is incremented at the rate of Rs.10/- for every Rs.200/- thereafter?
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 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)
