# Calculating Annual Interest Rate

Aug 18, 2009

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?

## Calculating YIELD From Interest Rate And Tenure

Jul 6, 2013

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?

## Compound Rate: Annual Growth Rate %

Jun 4, 2007

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%

## How To Calculate Trend Line Growth Rate (as Annual Percentage Growth Rate)

Feb 13, 2014

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.

## How To Determine Annual Rate Increase

Jan 12, 2014

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?

## Calculate APR (Annual Percentage Rate)

Feb 13, 2010

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.

## Median Hourly & Annual Rate In Same Column

Mar 24, 2008

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.

## How To Calculate Percentage Rate Increase With Annual Summary

Jun 6, 2014

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.

## Interest Rate Function

Mar 6, 2007

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?

## Calculate Daily Interest Rate

Nov 8, 2008

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.

## Compound Interest Rate Formula

Jan 27, 2007

I 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

## How To Calculate Interest Rate For Loan Product

Jan 31, 2014

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

## VBA Code For NPV Function With Variable Interest Rate?

Feb 2, 2014

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?

## Interest Rate Calculation With Payment Increases

Mar 4, 2014

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?

## Effective Rate Calculation, Interest Only Loan

Aug 27, 2008

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.

## 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.

## Finding Interest Rate Using Loan Constant - Iterative Calculation

Apr 9, 2014

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

## Calculate 10% Or 20% On Investment Form Depending On Interest Rate In Column

May 25, 2009

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%.

## Excel 2010 :: Multiplying Price By Variable Number Of Years And Annual Compounding Interest To Price

Sep 5, 2012

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.

## Calculating Compound Interest

Aug 6, 2006

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?

## Quarterly Interest Calculating Formula

Oct 21, 2009

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 ?

## Formula For Calculating Partial Year Interest

Feb 4, 2014

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.

## Basic - Calculating Interest And Time Till Pay Off

Feb 20, 2014

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."

## Average Daily Balance - Recursive Equation For Calculating Interest

May 21, 2013

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.

## Formula For Calculating Warehouse Picking Rate?

Mar 11, 2014

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.

## Excel 2007 :: Calculating IRR Using Rate Function?

Aug 11, 2012

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.

## Excel 2007 :: Calculating Sales Close Rate?

Jun 13, 2014

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.

## Calculating Annual Return On Investment For Real Estate Investment?

May 5, 2012

What formula to use to show the Annual ROI for a real estate investment property (single family). I believe I have all my figures to calculate WITH (acquisition amount, annual net income, etc.) -- but I can't figure out how to determine the ROI.

Or - is determining that % even possible/logical?

## Calculate Of Interest With Different Interest Rates Per?

Dec 29, 2013

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.
