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.

Am trying without success to create a formula to calculate average daily balance from a ledger that has a variable amount of entries per month. The variability of # of entries has me stumped. For example:

Formula to calculate a daily compound interest based on the higher rate of the two rates for the first 5 years, then after 5 years the calculation would only be based solely on the blocked rate.

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.

What I am trying to do is to create a formula for the attached spreadsheet - that calculates the daily compounding interest based on the higher rate of the two rates for the first five years then after 5 years the calculation should only be based solely on the blocked rate.

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 ?

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?

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 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 data was taken in 15 min intervals and is organized by date. I have one column with the date and time and another column with the data. I need to find the average for each day. I have almost a years worth of data. Is there any formula I can enter to find the values in a given day and return the average of the values (without having to select the data for each day)? I want to be able to copy the formula down a column with the value per day.

Charter default premium is a calculated as a rate on outstanding charter hire.

Therefore if charter period is 1 year and daily hire is 20,000, outstanding charter hire (policy limit) at inception would be 20,000 x 365 = $7,300,000

However, by day 365 outstanding charter hire and prevailing policy limit would only be 20,000 x 1 day = $20,000

The premium is calculated on a daily pro rata basis on the reducing outstanding amounts.

I've calculated the premium on the attached spreadsheet assuming hire is monthly not daily, but it would be too laborious to try and calculate that for 12 months or more on a daily basis. What I'm hoping is that there's a formula, covering the range of data, presumably using the calculation on the first day and the last day, but which cuts out all the intermediate steps.

I have a sheet with daily data starting from 01/01/2000. I want to calculate daily averages for each quarter (i.e 2000Q1 value will be the average of values between 01/01/2000-31/03/2000, 2000Q2 will be average of values between 01/04/2000-31/06/2000, 2000Q3 average(01/07/2000-31/09/2000) and 2000Q4 will be the average of (01/10/2000-31/12/2000) etc. for all years afterwards.

I want to have the values in the corresponding cells starting with range ("e2")

I have a table of data covering the last 9 months based on values automatically collated from 15 minute intevals. The date/time is in column A (01/01/2009 00:00) with the data collected in column D.

My wish is to get the average daily data from column D and I am slowly losing my head!!!

Is there anyway of getting a formula to auto-average the daily values bearing in mind there are currently 96 daily entries.

I have tried converting the first 5 digits of column A to numeric (i.e. 31894 for 01/01) then trying to write a formula saying =average(D1:D24577,if(range="31894",1)).

I can now see a simpler way but am so confused after an hour or so of trying.

Each day has 96 readings so I need an auto adding formula. average column cell A would say =average(D1:D96).

Is there are way to have the cell below auto-update itself to look at the next 96 values and so on and so forth?

I need to count the daily average of a task to a week ending number. I need to see the current average after each day during the week. Example – Mon = 2, Tues = 4 AVERAGE is 3 – Wed = 2 AVERAGE IS NOW 2.6…and so on averaging out after each day is added.

I'm trying to build a formula that allows me to see which item is the highest trending over a period of time I input.

I figured out the way how to select data between specific Start and End dates, but don't know how to interpret "trending" in a formula.

I was thinking maybe highest jump from beginning to end of interval, but what if it's a new item that was launched halfway through the interval and does poorly throughout, that would still be "trending" under that rationale....

For the small database in my example workbook, I would like to apply credits earned at a later date to the oldest charges and create a "To Date" balance. After creating the "To Date" balance, I would like to select the smallest "To Date" balance as a way to identify the first charge that has no payment. Please see the attached for more clarity and additional information. The last column shows the desired results.

I am performing a given exercise every day in the month of march. I have the dates all lined up in my spreadsheet, with the sum at the bottom. What I want to do is have another cell that will give me my daily average of performance. For example today is the 2nd and I have performed this exercise 360 times, making my daily average 130 per day. If I performed 200 of the exercise tomorrow I would have a grand total of 560 repetitions making my daily average roughly 186 per day (the day, march 3 divided by the number of repetitions, 560) and so on and forth.

I need a formula that will automatically calculate that daily average as I progress with the month. But I want the calculation to stop at the end (i.e. I don't want it to continue as the year progresses, meaning the divisor keeps going throughout the rest of the year). Basically, I guess, I am looking to fill in the daily repetition and the divisor to increase each day as I do so. My average is to be displayed in cell B36, so today my formula should read (=2/B36) and on March 31st the formula would be (=31/B36).

I'm working on a time series dataset with a time step of 15 minutes. I need to calculate daily average of the several variables. So let column "A" be the "date-time" column, let column "B" be the "variable column" and column "C" be the "average column", I need a function that calculated in C1 cell the average of B1 to B95 cells, in C2 cell the average of B96 to B190 cells, in C3 cell the average of B191 to B285 etc.

How to go about fixing my spreadsheet so I am not having to manually update it each day..here is my forumla I am currently using...=(AVERAGE($D$2:$AH$2)-C5)*AI5...basically i need the cell below in D2 to change as every day a new day rolls off..for example the following day I need this formula to be =(AVERAGE($E$2:$AH$2)-C5)*AI5 ....so just that day changes.....do I need to use an If/then statement? if so how?

I have a workbook with two sheets - DATA and SUMMARY. DATA has two columns - date and data_value. Data will be added to this sheet on a regular basis

SUMMARY has two columns - month and average

In the column for average I would like a formula to calculate the average of data_value for each month without having to manually determine the range for the particular month.

I have data in the following format (columns A & B):

Code: Day Value 1/1/2002 2.1 2/1/2002 4.8 3/1/2002 0.1 " " " " " " 31/12/2011 5.2

I'd like to be able to write a formula so that I can get the daily data averaged over each month, e.g so that I have something like:

Code: Day Value Jan 2002 3.3 Feb 2002 4.3 Mar 2002 3.1 " " " " " " Dec 2011 4.2

I'd like the data in monthly averages so that I can graph them. I have read about array formulas and averageif statements, but I can't seem to combine them to make them work.

I have a spreadsheet that contains developer related data. I want to be able to do a weekly analysis of average construction time and costs. The problem I am running into is properties enter rehab phase and exit rehab phase throughout the week.

For example:

I want to know the average $ spent and total rehab time week 1 of april. I may have 4 homes that entered rehab that week and 3 that move out of rehab that week. Moreover, I need to ensure those homes that entered and are still in rehab for that week are counted. How do I accomplish this feat?

I have a set of 7 years daily rainfall data. I need to calculate the daily average of rainfall from this 7 years data set. I don't wanted to calculate it by for example copying and pasting the first day rainfall of each year rainfall to a new sheet and average it for all the days. I need to calculate it all at a time.

I have two time series which span several years. The first series measures stock levels on every Friday (52 values a year). The second series measures the price level every weekday (260 values a year).

I'd like to condense the daily data in to a weekly average, can I do this easily? For example, I could manually use the Weeknum function to calculate the week number of each daily price data, then find the average daily price for each week, thus giving me 52 values which I can compare to the weekly stock series. Is there an automatic, fast way of doing this? Alternatively, I'd be happy to settle with a monthly average. Is this possible via macro's or does VBA need to be used?
