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.

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?

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 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?

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.

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

1Loan Amount$10,500,000 0.0730041581143804

2Term 10 years

3Rate

4Amortization30 years

5Constant (K) =PMT(B3/12,(B4*12),-1000)*0.012

6Annual Payment$766,544

7Monthly Payment$63,879

Example is attached.

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%.

In between the process involves changing the currency from US$ to PKR, make some calculations, and changing back the currency again to US$.

The default rate of currency exchange is set to ave 60 (C12). However if the user knows the current rate he can put it manually in C6 and sheet will make all the calcs on this instead of using the default rate.

Problem:

Everything is working just too perfect. But probs occur when i manually enters the exchange rate.

It does successfully changes the US$ to PKR and calculates everything perfectly but doesnt reverts the final cost back to US$ successfully instead it keeps using the default value instead of user's value

My problem is trying to identify the applicable rate in a range of dates that are not consistent in every case. I have a number of orders that span 4 years. The rate charged has changed over time and therefore I'm trying to find what the applicable rate would be for that time frame. For example one of my orders was created on 2/27/2012 with a specific item, then again the same item was ordered on 9/10/2013 and I need to find what the rate should have been for both of those orders during those rate periods. I've attached a sample sheet with the 2 tables I've been trying to assess. I've tried using mulitple IF and VLOOKUP formula's but it doesn't work they way I need it to due to the inconsistency in Table 2. H

I have a problem calculating a total interest for an input period that has different interest rates. You can see the attached file: INTEREST.xls

I have used a function but the result comes out wrong. Can I fine tune it or do I have to change my method of calculating.

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%

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.

View 6 Replies View RelatedI am having a bit of a problem creating a formula for this report that I have to update every week. I need to be able to find the room nights and net room revenue values for the specific rate code in the "MATRIX" workbook.

On "CURRENT REPORT," I need D4 to pull up the value on "MATRIX" that equals "Room Nights" in column H and "CONABC" in column J. The same thing needs to happen for F4 but with "Net Room Revenue" in column H. The full report has about 500 of these codes in column J, and I need a formula that I can copy easily and will not be affected if codes are added or removed. This is super last minute - I need to finish this report by tomorrow morning, so take a look at the attachments.

(1) I need to work out the value of 2 years worth of interest on a loan - details would be

Loan = 30,180.00

interest = 14.90% pa (calculated daily)

term of loan would be 60 months

I am currently using an ammortisation speadsheet which calculates the interest per month etc ... at this time I simply highlight and calculate the interest which would be two years worth ...

the problem is this calculation varies from the bank interest calculations (although the repayments are the same and the total interest payable amounts are the same)

The banks calculations are said to be done on the basis that the minimum monthly repayment is met and there are no additional fees thrown in ... so I cant understand the difference ...

(2) In addition to the above question, but working on the same loan, traditionally amortisation tables calculate the amount of the repayments, the interest component and the principal component ... some include a column where you can factor in additional repayments on a row by row basis (like the one I am referring to) the table assumes that the payment is made on the due date ...

what I would like to be able to do is

(a) insert the actual payment dates

(b) if no payment is recorded for that period, automatically insert an overdue fee

I'm trying to find a formula that will give me the following:

Rent is $2.00 a month with a 3% escalation each year. What is my Rent after 5 years?

Now the other thing is that I need the number of years to be a formula that counts the number of columns with data up to the column with $0.00.

I have a macro that formats a spreadsheet to show outstanding invoices, grouped and subtotalled by month. To add to this I need VBA code that will use the subtotals to calculate interest on overdue accounts.

Interest becomes due a calender month after the month in which the invoice is dated. So for example a January invoice would start to accrue interest on 1st March.

Below is the subtotals code (sadly the totals don't adjust if data is added or removed but perhaps that is another question for another day.)

Dim LastRow As Long

Dim NextMonth As String

Dim R As Long

Dim Rng As Range

Dim SubAmount As Currency

Dim ThisMonth As String

Dim TotalAmount As Currency

Dim Wks As Worksheet

Set Wks = Worksheets("Reconciliation")

LastRow = Wks.Cells(Rows.Count, "A").End(xlUp).Row

Set Rng = Wks.Range(Cells(2, "A"), Cells(LastRow, "D"))

attached the spreadsheet that I need help with in that same thread. Please check out the spreadsheet via: [url]

Here's my issue:

I'm trying to be debt free roughly around 10-11 years years based on my current plan. SO, what I am trying to do is figure out what I can do with my savings at 1, 2, and a 3 % rate of return in a savings account that is compounded monthly after that debt free point. My time frame for results are 5-10-15-and 20 years.

In column B I could have blank, text or text containing the word "track" or "Track". In column C I could have Blank, "yes" or "Yes" or "no" or "No"

Only if B text contains "track" or "Track" and/or C contains "yes" or "Yes" I want to conditionally format B.

This does not work:-

=OR(FIND("track",B1,1),FIND("Track",B1,1),C1="yes",C1="Yes")

I have a person who was paid £1000 pension pa for ten years. I've found out that the pension should have been split 50/50 with half increasing by 5% pa. Thus in year 1 total pension would be £1000. In year 2 the total pension would be £1025 ((£500 x 1.05) plus £500)

I know that in year 10 the total pension should be £500 (non increasing) plus £814 (£500 x 1.05 to the power of ten). My problem is how do I work out a formula which calculates the total arrears due in year ten? I'm thinking the arrears due after the ten years is £314 but something is telling me it's a lot more.

I have created a template that I use to determine interest calculations (it is based on simple daily interest, but monthly compounding and adjusts for any variations in interest rates during the month), and it seems to work fine so far.

However, I am trying to make it better and would like to eliminate as much manual input as possible. I have attached an example of the template to help explain what I would like to achieve

The Running Balance is dependant on column "J" - Interest for the Month. At the moment, I am manually adding up interest accumulated for the month, however if I add one cell too high or miss a cell when adding, it can lead to compounded problems further down. So in short I am looking for a method that would automatically calculate "interest for the month" by adding all the amounts in column "I" (Interest Daily) at month end for that month only (dates are entered in Column B)

In the attached template, grey areas indicate capital movements and/or interest rate changes that may occur during a month (ie movement in the month in question that affects the daily interest calculated)

I hope I've covered everything!

Any help in this regard comes most appreciated. If anything is unclear, I will do my best to explain what I am trying to achieve in greater detail.

I have a column of years and a column of numbers representing annual

amounts placed in a savings account for the year. I would like to calculate

the balance of interest earned added to the balance of the account and then

calculate the interest earned on the accumulating amounts each year. The

results would be the account balance displayed in an adjoining column. So

far, I have not found a worksheet function for that. Could someone point me

in the right direction? Perhaps there should be several columns of data?

How can I find the total of interest (or and expense) during a given calendar range

Data is as follows

Date Type Amount

4/1/11 Interest 4.00

4/15/11 charge 22.00

5/1/11 interest 3.00

I want a cell to compute the interest in april only.

I have tried =sumif(range, end date, amount_range)- sumif(range, beg date, amount_range)

but how do I nest the type argument into the argument

Possible approaches advanced filter? and function? add another column that uses an if statement to do interest only and do the sumif statement above I was hoping to have a drop down box that could have interest, COGS, beside it and april, may, june above it

I am trying to set up a budget for my self. Of course I am trying to make it as complicated as possible.

I have done searches online and that is how I found this forum. I am finding amortization formulas, but not what I want

Here is my question.

I have two fields, Mortgage and auto loan

I want to have a field that does a calculation for me.

I know following fields as an example making numbers up

Interest rate is fixed at 5.5%

Amount left on loan is 150,000

Loan is fixed at 30 years with 28 years left

I want to run a formula so when I make a monthly payment of 1000 dollars how much of that goes to interest, how much to principle (not to make this complicated even more, but let say that I have 200 escrowed which I am not sure if that has interest calculated on(I don’t think so as it is property tax?))

Same example for car loan.

5 year loan, 4.5% interest, payment 438 a month.

does anyone know how to calculate the interest so it matches this? .......
