# Calculating Annual Interest Rate

Aug 18, 2009If 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?

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?

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.

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?

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.

View 6 Replies View RelatedWhat 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: 8ยข/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.

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 4 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 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 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.

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

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%.

View 5 Replies View RelatedI 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.

Windows 7 Ultimate / Excel 2010

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?

I use Excel 2007 , I created Interest calculator , on Daily basis , to caluculate interest , compounded quarterly.

But I want to make it compact , as d one I created is long enough.

A3 = Principal Amount

B3 = Date of Investment

C3 = Interest as on Date

D3 = Number of Days , amount Invested {comes out of formula set}

E3 = Rate of Interest

Now in F3 I want the Interest amount , compunded quarterly.

Some times NUMBER OF INVESTED CAN BE LESS THAN 90 DAYS TOO...then what ?

I have developed a financial calculator that asks the user for the "input date" which is used to record balances as of the input date. My interest calculation for the first year is based on the current date compared to the input date. For example, if the user is keying in a current balance of 10,000 @ 10% interest, and the "statement date" or "input date" is 12/30/2013, and the current date is today, 2/4/2014, then it should calculate interest for the entire year of 2014. It is not doing that. It calculates $3 interest.

But if input date is 6/30/2013 with current date of 2/4/2014, it seems to work OK. It calculates interest of $504 in that case. It appears to get messed up with the year transition between current date and input date. The formulas I have listed below appear to work fine except when the input date is 2013 for the year and the current date is 2014. The formula does not "see" that input date was last year. There must be a minor tweak to formula I am overlooking.

Cell C2 = Today's Date=TODAY()

Cell C3 = Input date (user keys in date in mm/dd/yyyy format)

Cell E2 = "translate input date to year format" =DATE(YEAR(C3),12,31)-C3

Cell E3 = Investment Rate

Cell G2 = yr 1 interest rate adjusted =(E3/1)*($E$2/365)

Cell C21 = Current Balance

Cell D21 = Interest Yr1 = C21*G2

I need the interest calculation to account for partial year accrual.

I've uploaded my spreadsheet. I asked my professor if our formula had to take into account whether or not our payment would be changing. As long as I calculated the initial amount - which worked out to be around 30 dollars, I could assume I paid that amount for the entirety.

ASSIGNMENT 4

My latest Mastercard statement shows a balance due of $1,696.96.

Based on recent bills, assume that the minimum payment amount is computed as follows

(balance_owed)*(annual_interest_rate/12) * 2, then rounded to the nearest whole dollar amount.

The minimum payment amount is the amount calculated above or $25.00, whichever is the greater amount.

The annual interest rate for purchases is 11.24%. If I make no more purchases and always pay my bill on time how many years and months will it take be pay it off at the current minimum payment amount each month?

How much total interest would I pay if I repay the loan this way?

What fixed monthly payment amount would pay off the debt in 2 years?

Assume monthly compounding of interest. All calculations are to be done in the Excel worksheet.

The functions NPER() and PMT() will be useful. Note that either the Present Value or Payment amount should be negative (not both) because of conventions concerning the direction of cash flow."

I create this spreadsheet as a loan schedule using average daily balance method. (1/payment is constant, fortnightly 2/interest is 5.5% per annum)

In the interest column, at the beginning of each month ( when the day is 1) the interest will be added up from calculation of previous month daily balance.

My idea is that at interest column(let start at 1/08/2013) if (day(A49)=1, average the 30 or 31 cells above E49, 0).

I will manually make adjustment for February where 28 or 29 days applicable.

I am trying (and failing miserably) to create a fomula to 'score' my pickers in a warehouse environment.

The basic variables are;

1) Units (Total quantity of units on picklist)

2) Lines (Number of different products on picklist)

3) Time (Total time to complete pick)

To give an example, if Units = 8, Lines = 1 and Time = 00:01, I want 'Score' to = 100.

(Based on benchmark, rounded down to lowest common denominators)

The added complication I face is the relationship between Lines and Units; it would take someone longer to pick 1 unit from 10 lines than 10 units from 1 line.

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 want to set up an Excel spread sheet where I can put my total number of sales appointments for the month and the percentage of those I closed. I've done this before, but for the life of me I can't remember the formula I used & I know it's a very simple one! I'm using Office 2007.
