I would like a function which works like the NPV function except that the interest rate should be variable and a range rather than a single number.
Is it possible to see the code for the excel NPV function so that I can modify it?
Or alternatively has seen such a function?
Is there a function that calculates what interest rate is needed to turn a $2000 investment into $9000000 in 30 years based on compounding interest?
View 9 Replies View RelatedSome 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.

View 9 Replies View RelatedI am trying to calculate the effective annual interest rate earned on an investment and find the results are close but not really accurate. I suspect because I have not included the frequency of interest in my existing formula
r = n * nt root (A/P-1)
where;
r = the effective interest rate
n = the number of times interest is added per year
t = the total number of years
A = the current value
P = the original value
The 2 problems I face are;
1. Confirming this formula would provide the correct answer (need maths expert here) &
2. How would "nt root" (as in sqr root, but using the product of the years and frequency) be used in Excel
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 keep coming across bonds having different annual interest rates and different compounding frequencies (quarterly, half yearly and yearly).
I know there is a YIELD function, but it requires so many inputs. I was wondering whether we can calculate cumulative yields just from annual interest rates, compounding frequency and investment duration?
I have a capital lease amortization schedule with annual increases to monthly rent that I am trying to solve for an interest rate such that the balance nets to zero at the end of the term. I am calculating on a monthly basis; in other words, principal minus monthly payment plus monthly interest expense equals ending monthly balance is calculated in each row each month. The present value is known, payment term is known, future value is zero, and the payment amounts increase annually. These assumptions may change for new leases so ideally the solution would be dynamic, adjusting for shorter/longer terms, etc. Here is an example of my assumptions:
Payment start date: 8/1/13
Term end date: 10/31/2025
Rent length in months: 144
1st months rent: $500,000 - payments are due at the beginning of the month and are paid monthly
Annual rent escalation: 3% - i.e. 1st 12 months is $500k/month, 2nd 12 months at $515K, etc.
Beginning NPV: $75M
Ending value: $0
Imputed annual interest rate: UNKNOWN
I'm not sure if this is relevant, but the monthly payment is allocated between principal and interest. Monthly interest expense is calculated as the current balance * (imputed interest rate / 12).
Currently, I've plugged the interest rate such that my ending balance is 0, however I was hoping to calculate it on the fly as opposed to manually plugging it.
how to calculate annual interest rate with these inputs? Is there a way to make the rate function work with payment increases?
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.

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%.

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 a way to calculate commission for my sales reps. The commission is based off a calculated value in H39 of a sheet that I have developed.
They get 7.5% of the value when between $1 - $100,000, example: sales of $50,000 = $3,750 in commission.
If the value in H39 is > $100,000 but $250,000 but $500,000 they get 7.5% on the first $100,000 plus 5% on the amount between $100,001 and $250,000 plus 3% on the remainder between $250,001 and $500,000 plus 2% on any amount >$500,000 example: sales of $800,000 = $7,500 (7.5% on first $100,00) plus $7,500 (5% on the next $150,000) plus $7,500 (3% on the next $250,000) plus $6,000 (2% on the sales >$500,000 for a total of $28,500.
I am having to copy and paste rows of data into a new worksheet where the rows sizes change and I am wanting to add a new row at the end of the pasted rows but with the sumation formula to add the relevant column
e.g copy range B14:AA17 with in this case columns E to AA holding the numerical values. Therefore I wish in cell E18 to sum the value of E14:E17 and so on ending with cell AA18 holding the sum of AA14:AA17
As these vary I have all relevant variables, Range to add sumation values to eg E18:AA18
Start Cell E14 and so on.
I tried adding "=SUM(x:d)" where x and d are vars relating the the column cell required eg x = E14 and d = E17

View 2 Replies View RelatedI 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 am using excel 2007. I am trying to calculate the internal rate of return, without creating an array. I figured out that I can use the rate function to give me the same answer as the IRR function if I have one payment stream of say 36 months @ 1000. Where I am an running into trouble is if I have second payment stream of 6 months extension of 1500. Rate # pay 36 amt 75 PV = 5000 FV 500 , How to handle the the last 6 months ?
This is the situation
asset costs is 5000
monthly lease is 75 for 36 months
extension for 6 months is 125
end of lease buyout is 500
what is the internal rate of return without creating an array.
I need J22 to multiply based on years in B22 AND increase 5% for each of those years (compounding) after two years (excludes year 1 from 5% increase). In addition the cell needs to remain blank if D22 is blank. B22 = 1, then the stockprice needs to remain the same, and only increase by 5% after year 1.
Currently...
B22 = a number of years indicated by the formula: =IF(A22="","",DATEDIF(A22,I3,"y"))
J22 =IF(ISNA(VLOOKUP(D22,stockprices,2,FALSE)),"",VLOOKUP(D22,stockprices,2,FALSE))
Example:
If J22 stockprice lookup is $1000.00, and the number of years listed in B22 is 6, then the reported value in J22 needs to be $1494.40.

View 1 Replies View RelatedThe 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%

Is it possible to use a variable in Countif?
See attached sheet. When a number repeats for the 3rd time, I need to reset the
Countif function.
For example;
Countif($A$5:A20,A20).

We are counting numbers until they repeat for a 3rd time and then we start the count again at that point.
I'd like to compare values from different sheets. My sheets contain data from different years. I have sheets named 2000, 2001, 2002, 2003.... I also have a sheet named "compare". Now I'm using functions like: =('2008'!J13/'2007'!J13)-1
which gives me the relative change between years 2007 - 2008 in the cell J13.
I'd like to use the sheet name as variable. For example: "year 1" is given in cell A1 and "year 2" given in cell A2. Then I could enter (for example) 2007 in cell A1 and 2008 in cell A2. How can I use these cell values in the function? I’ve tried something like: =('A2'!J13/'A1'!J13)-1. I assumed that 'A2'!J13 would be the same as '2008'!J13. It didn’t take me long to figure out that doesn’t work. What would be the right way to do this?
MAX function with a variable range. I want find the highest value in a changeable range in a column. The problem for me is, how can I automatically change the range where the highest value is returned.
Here is an example:
Cell A1: 14
In cell A1 is the number entered that specifies the range. In this example the range is 14 rows =MAX(A18:A31).
A2 126.36
A3 126.16
A4 124.93
A5 126.09
A6 126.82
A7 126.48
[Code] .....
Using =MAX(A18:A31) returns 128.57. So far so fine.
But what is the MAX function if the range value refers to the number entered in cell A1? If I change the value in A1 from 14 to 20 how can I make the MAX function flexible that it refers to cell A1 as the range value?
Using the value 20 in cell A1 the MAX function would be =MAX(A12:A31). I can change this manually of course but I want a MAX function that refers to cell A1 as the range value.
I want also mention that the data series is update every day, so that each day a new value is added in column A, e.g. A32, A33, A34. and so on.

It does not work.
